📖 What it is MedlinePlus · NLM

Metformin is used alone or with other medications, including insulin, to treat type 2 diabetes (condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood). Metformin is in a class of drugs called biguanides. Metformin helps to control the amount of glucose (sugar) in your blood. It decreases the amount of glucose you absorb from your food and the amount of glucose made by your liver. Metformin also increases your body's response to insulin, a natural substance that controls the amount of glucose in the blood. Metformin is not used...

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

1.1Limitations of Use Saxagliptin and metformin hydrochloride extended-release tablets are not recommended for the treatment of type 1 diabetes mellitus or diabetic ketoacidosis.

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Administer once daily with the evening meal. ( 2.1 ) Individualize the starting dosage based on the patient’s current regimen then adjust the dosage based on effectiveness and tolerability. ( 2.1 ) Do not exceed a daily dosage of 5 mg saxagliptin/2,000 mg metformin HCl extended-release.

( 2.1 ) Swallow whole. Never crush, cut, or chew. ( 2.1 ) Limit the saxagliptin dosage to 2.5 mg daily for patients also taking strong cytochrome P450 3A4/5 inhibitors (e.g., ketoconazole).

( 2.3 , 7.1 ) Assess renal function prior to initiation of saxagliptin and metformin hydrochloride extended-release tablets and periodically thereafter. ( 2.2 ) o Do not use in patients with eGFR below 30 mL/min/1.73 m 2 . o Initiation is not recommended in patients with eGFR between 30 to 45 mL/min/1.73 m 2 . o Assess risk/benefit of continuing if eGFR falls below 45 mL/min/1.73 m 2 . o Limit the saxagliptin component to 2.5 mg daily if eGFR is less than 45 mL/min/1.73 m 2 . o Discontinue if eGFR falls below 30 mL/min/1.73 m 2 .

Saxagliptin and metformin hydrochloride extended-release tablets may need to be discontinued at time of, or prior to, iodinated contrast imaging procedures. ( 2.4 )

2.1Recommended Dosage and Administration Individualize the starting dosage of saxagliptin and metformin hydrochloride extended-release tablets based on the patient’s current regimen and the available strengths of saxagliptin and metformin hydrochloride extended-release tablets [see Dosage Forms and Strengths ( 3 )] . Administer saxagliptin and metformin hydrochloride extended-release tablets once daily with the evening meal, with gradual dose titration to reduce the gastrointestinal side effects associated with metformin HCl [see Adverse Reactions ( 6.1 )] .

The recommended starting dosage of saxagliptin and metformin hydrochloride extended-release tablets in patients who need 5 mg of saxagliptin and who are not currently treated with metformin HCl is one saxagliptin and metformin hydrochloride extended-release tablet containing 5 mg saxagliptin and 500 mg metformin HCl extended-release once daily with gradual dose escalation to reduce the gastrointestinal side effects due to metformin HCl. In patients treated with metformin HCl, the recommended starting dosage of saxagliptin and metformin hydrochloride extended-release tablets should provide metformin HCl at the dose already being taken, or the nearest therapeutically appropriate dose.

Following a switch from metformin HCl immediate-release to saxagliptin and metformin hydrochloride extended-release tablets, closely monitor glycemic control and adjust the dosage accordingly. Patients who need 2.5 mg saxagliptin in combination with metformin HCl extended-release may be treated with saxagliptin and metformin hydrochloride extended-release tablets 2.5 mg/1,000 mg. Patients who need 2.5 mg saxagliptin who are either metformin HCl naive or who require a dose of metformin HCl higher than 1,000 mg should use the individual components.

Gradually titrate the dosage of saxagliptin and metformin hydrochloride extended-release tablets, as needed, after assessing therapeutic response and tolerability, up to a maximum recommended dosage of saxagliptin and metformin hydrochloride extended-release tablets (5 mg for saxagliptin and 2,000 mg for metformin HCl extended-release orally once daily). Inform patients that saxagliptin and metformin hydrochloride extended-release tablets must be swallowed whole and never crushed, cut, or chewed. Occasionally, the inactive ingredients of saxagliptin and metformin hydrochloride extended-release tablets will be eliminated in the feces as a soft, hydrated mass that may resemble the original tablet.

If a dose is missed, advise patients not to take an extra dose. Resume treatment with the next dose.

4 CONTRAINDICATIONS Saxagliptin and metformin hydrochloride extended-release tablets are contraindicated in patients with: Severe renal impairment (eGFR below 30 mL/min/1.73 m 2 ). Acute or chronic metabolic acidosis, including diabetic ketoacidosis. Diabetic ketoacidosis should be treated with insulin.

A history of a serious hypersensitivity reaction to saxagliptin, metformin HCl, or any of the ingredients in saxagliptin and metformin hydrochloride extended-release tablets. Reactions such as anaphylaxis, angioedema, or exfoliative skin conditions have been reported [see Warnings and Precautions ( 5.6 ) and Adverse Reactions ( 6.2 )]. • Severe renal impairment (eGFR below 30 mL/min/1.73 m 2 ). ( 4 ) • Metabolic acidosis, including diabetic ketoacidosis.

( 4 ) • History of a serious hypersensitivity reaction (e.g., anaphylaxis, angioedema, exfoliative skin conditions) to saxagliptin, metformin HCl, or any of the ingredients in saxagliptin and metformin hydrochloride extended-release tablets. ( 4 )

⚠️ Warnings and Cautions ~2 min read ▾

5 WARNINGS AND PRECAUTIONS • Pancreatitis : There have been postmarketing reports of acute pancreatitis. If pancreatitis is suspected, promptly discontinue saxagliptin and metformin hydrochloride extended-release tablets. ( 5.2 ) • Heart Failure : Consider the risks and benefits of saxagliptin and metformin hydrochloride extended-release tablets in patients who have known risk factors for heart failure.

Monitor patients for signs and symptoms. ( 5.3 ) • Vitamin B 12 Deficiency : Metformin may lower vitamin B 12 levels. Measure hematological parameters annually.

( 5.4 ) • Hypoglycemia with Concomitant Use of Insulin or Insulin Secretagogues: Consider a lower dosage of insulin or insulin secretagogue when used in combination with saxagliptin and metformin hydrochloride extended-release tablets. ( 5.5 ) • Hypersensitivity-Related Events: There have been post-marketing reports of serious hypersensitivity reactions, such as anaphylaxis, angioedema, and exfoliative skin conditions in patients treated with saxagliptin. If hypersensitivity reactions occur, discontinue saxagliptin and metformin hydrochloride extended-release tablets, treat promptly, and monitor until signs and symptoms resolve.

( 5.6 ) • Arthralgia : Severe and disabling arthralgia has been reported in patients taking DPP4 inhibitors. Consider as a possible cause for severe joint pain and discontinue drug if appropriate. ( 5.7 ) • Bullous Pemphigoid : There have been postmarketing reports of bullous pemphigoid requiring hospitalization in patients taking DPP-4 inhibitors.

Tell patients to report development of blisters or erosions. If bullous pemphigoid is suspected, discontinue saxagliptin and metformin hydrochloride extended-release tablets ( 5.8 ).

5.1Lactic Acidosis There have been postmarketing cases of metformin-associated lactic acidosis, including fatal cases. These cases had a subtle onset and were accompanied by nonspecific symptoms such as malaise, myalgias, abdominal pain, respiratory distress, or increased somnolence; however, hypothermia, hypotension and resistant bradyarrhythmias have occurred with severe acidosis. Metformin-associated lactic acidosis was characterized by elevated blood lactate concentrations (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), and an increased lactate: pyruvate ratio; metformin plasma levels generally >5 mcg/mL.

Metformin decreases liver uptake of lactate increasing lactate blood levels which may increase the risk of lactic acidosis, especially in patients at risk. If metformin-associated lactic acidosis is suspected, general supportive measures should be instituted promptly in a hospital setting, along with immediate discontinuation of saxagliptin and metformin hydrochloride extended-release tablets. In saxagliptin and metformin hydrochloride extended-release tablets-treated patients with a diagnosis or strong suspicion of lactic acidosis, prompt hemodialysis is recommended to correct the acidosis and remove accumulated metformin (metformin HCl is dialyzable, with a clearance of up to 170 mL/minute under good hemodynamic conditions).

Hemodialysis has often resulted in reversal of symptoms and recovery. Educate patients and their families about the symptoms of lactic acidosis and if these symptoms occur instruct them to discontinue saxagliptin and metformin hydrochloride extended-release tablets and report these symptoms to their health care provider. For each of the known and possible risk factors for metformin-associated lactic acidosis, recommendations to reduce the risk of and manage metformin-associated lactic acidosis are provided below: Renal Impairment : The post-marketing metformin-associated lactic acidosis cases primarily occurred in patients with significant renal impairment.

The risk of metformin accumulation and metformin-associated lactic acidosis increases with the severity of renal impairment because metformin is substantially excreted by the kidney. Clinical recommendation… [Excerpted — this section continues on DailyMed.]

Adverse Reactions in Placebo-Controlled Trials in Adults with Type 2 Diabetes Mellitus Metformin HCl In placebo-controlled monotherapy trials of metformin HCl extended-release, diarrhea and nausea/vomiting were reported in >5% of metformin-treated patients and more commonly than in placebo-treated patients (9.6% versus 2.6% for diarrhea and 6.5% versus 1.5% for nausea/vomiting).

Diarrhea led to discontinuation of trial medication in 0.6% of the patients treated with metformin HCl extended-release. Saxagliptin The data in Table 1 are derived from a pool of 5 placebo-controlled clinical trials [see Clinical Studies ( 14 )]. These data shown in the table reflect exposure of 882 patients to saxagliptin and a mean duration of exposure to saxagliptin of 21 weeks.

The mean age of these patients was 55 years, 1.4% were 75 years or older and 48.4% were male. The population was 67.5% White, 4.6% Black or African American, 17.4% Asian, 10.5% other races and 9.8% were of Hispanic or Latino ethnicity. At baseline the population had diabetes for an average of 5.2 years and a mean HbA1c of 8.2%.

Baseline estimated renal function was normal or mildly impaired (eGFR ≥60mL/min/1.73m 2 ) in 91% of these patients. Table 1 shows common adverse reactions, excluding hypoglycemia, associated with the use of saxagliptin. These adverse reactions occurred more commonly on saxagliptin than on placebo and occurred in at least 5% of patients treated with saxagliptin.

🔄 Drug Interactions ~2 min read ▾

7 DRUG INTERACTIONS Strong CYP3A4/5 inhibitors (e.g., ketoconazole) : Coadministration with saxagliptin and metformin hydrochloride extended-release tablets significantly increases saxagliptin concentrations. Limit saxagliptin and metformin hydrochloride extended-release tablets dosage to 2.5 mg/1,000 mg once daily when coadministered with a strong CYP3A4/5 inhibitor. ( 2.3 , 7.1 ) Carbonic anhydrase inhibitors: May increase risk of lactic acidosis.

Consider more frequent monitoring. ( 7.2 ) Drugs that reduce metformin clearance: May increase risk of lactic acidosis. Consider benefits and risks of concomitant use.

( 7.3 ) See full prescribing information for additional drug interactions. ( 7 )

7.1Strong Inhibitors of CYP3A4/5 Enzymes Ketoconazole significantly increased saxagliptin exposure. Similar significant increases in plasma concentrations of saxagliptin are anticipated with other strong CYP3A4/5 inhibitors (e.g., atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, ritonavir, saquinavir, and telithromycin). The dose of saxagliptin and metformin hydrochloride extended-release tablets should be limited to 2.5 mg of saxagliptinwhen coadministered with a strong CYP3A4/5 inhibitor [see Dosage and Administration ( 2.3 ) and Clinical Pharmacology ( 12.3 )] .

7.2Carbonic Anhydrase Inhibitors Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide) frequently causes a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with saxagliptin and metformin hydrochloride extended-release tablets may increase the risk for lactic acidosis.

7.3Drugs that Reduce Metformin Clearance Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2]/multidrug and toxin extrusion [MATE] inhibitors such as ranolazine, vandetanib, dolutegravir, and cimetidine) could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology ( 12.3 )]. Consider the benefits and risks of concomitant use.

7.4Alcohol Alcohol is known to potentiate the effect of metformin on lactate metabolism. Warn patients against excessive alcohol intake while receiving saxagliptin and metformin hydrochloride extended-release tablets.

7.5Insulin or Insulin Secretagogue s Insulin and insulin secretagogues are known to cause hypoglycemia. Concomitant use of saxagliptin and metformin hydrochloride extended-release tablets with insulin or an insulin secretagogue may require lower dosages of insulin or the insulin secretagogue to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.5 )] .

7.6Drugs Affecting Glycemic Control Certain drugs tend to produce hyperglycemia and may lead to loss of glycemic control. These medications include the thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blocking drugs, and isoniazid. When such drugs are administered to a patient receiving saxagliptin and metformin hydrochloride extended-release tablets, observe the patient closely for loss of blood glucose control.

When such drugs are withdrawn from a patient receiving saxagliptin and metformin hydrochloride extended-release tablets, observe the patient closely for hypoglycemia.

8.1Pregnancy Risk Summary Limited available data with saxagliptin and metformin hydrochloride extended-release tablets or saxagliptin in pregnant women are not sufficient to determine a drug-associated risk for major birth defects and miscarriage. Published trials with metformin use during pregnancy have not reported a clear association with metformin and major birth defect or miscarriage risk [see Data] . No adverse developmental effects independent of maternal toxicity were observed when saxagliptin and metformin were administered separately or in combination to pregnant rats and rabbits during the period of organogenesis [see Data] .

The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with an HbA1c greater than 7 and has been reported to be as high as 20 to 25% in women with an HbA1c greater than 10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Considerations Disease-associated maternal and/or embryo/fetal risk Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, still birth and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Data Animal Data Saxagliptin In embryo-fetal development studies, saxagliptin was administered to pregnant rats and rabbits during the period of organogenesis, corresponding to the first trimester of human pregnancy.

No adverse developmental effects were observed in either species at exposures 1,503- and 152-times the 5 mg clinical dose in rats and rabbits, respectively, based on AUC. Saxagliptin crosses the placenta into the fetus following dosing in pregnant rats. In a prenatal and postnatal development study, no adverse developmental effects were observed in maternal rats administered saxagliptin from gestation day 6 through lactation day 21 at exposures up to 470-times the 5 mg clinical dose, based on AUC.

Metformin HCl Metformin HCl did not cause adverse developmental effect when administered to pregnant Sprague Dawley rats and rabbits up to 600 mg/kg/day during the period of organogenesis. This represents an exposure of about 2-and 6-times a 2,000 mg clinical dose based on body surface area (mg/m 2 ) for rats and rabbits, respectively. Saxagliptin and Metformin Saxagliptin and metformin coadministered to pregnant rats and rabbits during the period of organogenesis did not result in adverse developmental effects considered clinically relevant in either species.

Doses tested in rats provided exposure up to 100- and 10-times clinical exposure, and doses tested in rabbits provided exposure up to 249- and 1-times clinical exposure relative to the clinical dose of 5 mg saxagliptin and 2,000 mg metformin. Minor skeletal abnormalities associated with maternal toxicity were observed in rats. In rabbits, coadministration was poorly tolerated in a subset of mothers (12 of 30), resulting in death, moribundity, or abortion.

However, among surviving mothers with evaluable litters, maternal toxicity was limited to marginal reductions in body weight over the course of gestation days 21 to 29, associated with fetal body weight decrements of 7%, and a low incidence of delayed ossification of the fetal hyoid bone.

🧓 Geriatric Use 186 words ▾

8.5Geriatric Use Saxagliptin and Metformin Hydrochloride Extended-Release Tablets Elderly patients are more likely to have decreased renal function. Assess renal function more frequently in the elderly [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )]. Saxagliptin In the seven, double-blind, controlled clinical safety and efficacy trials of saxagliptin, a total of 4,751 (42%) of the 11,301 patients randomized to saxagliptin were 65 years and over, and 1,210 (10.7%) were 75 years and over.

No overall differences in safety or effectiveness were observed between patients 65 years of age and older and younger adult patients. Metformin HCl Controlled clinical trials of metformin did not include sufficient numbers of elderly patients to determine whether they respond differently than younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy and the higher risk of lactic acidosis.

Assess renal function more frequently in elderly patients [see Warnings and Precautions ( 5.1 ) ].

🆘 Overdosage 180 words ▾

10 OVERDOSAGE Saxagliptin In a controlled clinical trial, once-daily, orally administered saxagliptin in healthy subjects at doses up to 400 mg daily for 2 weeks (80-times the MRHD) had no dose-related clinical adverse reactions and no clinically meaningful effect on QTc interval or heart rate. In the event of an overdose, initiate appropriate supportive treatment as dictated by the patient’s clinical status. Saxagliptin and its active metabolite are removed by hemodialysis (23% of dose over 4 hours).

Contact the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Metformin HCl Overdose of metformin HCl has occurred, including ingestion of amounts greater than 50 grams. Hypoglycemia was reported in approximately 10% of cases, but no causal association with metformin HCl has been established.

Lactic acidosis has been reported in approximately 32% of metformin overdose cases [see Warnings and Precautions ( 5.1 )] . Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful for removal of accumulated drug from patients in whom metformin overdosage is suspected .

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Saxagliptin and Metformin Hydrochloride Extended-release Tablets Saxagliptin and metformin hydrochloride extended-release tablets contains two antihyperglycemic medications: saxagliptin, a dipeptidyl-peptidase-4 (DPP4) inhibitor, and metformin HCl, a biguanide. Saxagliptin Increased concentrations of the incretin hormones such as glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are released into the bloodstream from the small intestine in response to meals.

These hormones cause insulin release from the pancreatic beta cells in a glucose-dependent manner but are inactivated by the DPP4 enzyme within minutes. GLP-1 also lowers glucagon secretion from pancreatic alpha cells, reducing hepatic glucose production. In patients with type 2 diabetes mellitus, concentrations of GLP-1 are reduced but the insulin response to GLP-1 is preserved.

Saxagliptin is a competitive DPP4 inhibitor that slows the inactivation of the incretin hormones, thereby increasing their bloodstream concentrations and reducing fasting and postprandial glucose concentrations in a glucose-dependent manner in patients with type 2 diabetes mellitus. Metformin HCl Metformin improves glucose tolerance in patients with type 2 diabetes mellitus, lowering both basal and postprandial plasma glucose. Metformin decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization.

Unlike sulfonylureas, metformin does not produce hypoglycemia in patients with type 2 diabetes mrllitus or in healthy subjects except in unusual circumstances [see Warnings and Precautions ( 5.5 )] and does not cause hyperinsulinemia. With metformin therapy, insulin secretion remains unchanged while fasting insulin levels and day-long plasma insulin response may actually decrease.

12.2Pharmacodynamics Saxagliptin In patients with type 2 diabetes mellitus, administration of saxagliptin inhibits DPP4 enzyme activity for a 24-hour period. After an oral glucose load or a meal, this DPP4 inhibition resulted in a 2- to 3-fold increase in circulating levels of active GLP-1 and GIP, decreased glucagon concentrations, and increased glucose-dependent insulin secretion from pancreatic beta cells. The rise in insulin and decrease in glucagon were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal.

Cardiac Electrophysiology Saxagliptin In a randomized, double-blind, placebo-controlled, 4-way crossover, active comparator trial using moxifloxacin in 40 healthy subjects, saxagliptin was not associated with clinically meaningful prolongation of the QTc interval or heart rate at daily doses up to 40 mg (8 times the MRHD).

12.3Pharmacokinetics Saxagliptin and Metformin Hydrochloride Extended-release Tablets Bioequivalence and food effect of saxagliptin and metformin hydrochloride extended-release tablets was characterized under low calorie diet. The low calorie diet consisted of 324 kcal with meal composition that contained 11.1% protein, 10.5% fat, and 78.4% carbohydrate. The results of bioequivalence studies in healthy subjects demonstrated that saxagliptin and metformin hydrochloride extended-release combination tablets are bioequivalent to coadministration of corresponding doses of saxagliptin (ONGLYZA ® ) and metformin HCl extended-release as individual tablets under fed conditions.

Saxagliptin The pharmacokinetics of saxagliptin and its active metabolite, 5-hydroxy saxagliptin were similar in healthy subjects and in patients with type 2 diabetes mellitus. The C max and AUC values of saxagliptin and its active metabolite increased proportionally in the 2.5 to 400 mg dose range. Following a 5 mg single oral dose of saxagliptin to healthy subjects, the mean plasma AUC values for saxagliptin and its active metabolite were 78 ng•h/mL and 214 ng•h/mL, resp… [Excerpted — this section continues on DailyMed.]

💬 Information for Patients ~3 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide). Lactic Acidosis The risks of lactic acidosis due to the metformin component, its symptoms and conditions that predispose to its development, as noted in Warnings and Precautions ( 5.1 ), should be explained to patients. Patients should be advised to discontinue saxagliptin and metformin hydrochloride extended-release tablets immediately and to promptly notify their health care provider if unexplained hyperventilation, myalgia, malaise, unusual somnolence, dizziness, slow or irregular heartbeat, sensation of feeling cold (especially in the extremities), or other nonspecific symptoms occur.

Gastrointestinal symptoms are common during initiation of metformin treatment and may occur during initiation of saxagliptin and metformin hydrochloride extended-release tablets therapy; however, patients should consult their physician if they develop unexplained symptoms. Although gastrointestinal symptoms that occur after stabilization are unlikely to be drug related, such an occurrence of symptoms should be evaluated to determine if it may be due to lactic acidosis or other serious disease. Patients should be counseled against excessive alcohol intake while receiving saxagliptin and metformin hydrochloride extended-release tablets.

Patients should be informed about the importance of regular testing of renal function and hematological parameters when receiving treatment with saxagliptin and metformin hydrochloride extended-release tablets. Instruct patients to inform their doctor that they are taking saxagliptin and metformin hydrochloride extended-release tablets prior to any surgical or radiological procedure, as temporary discontinuation of saxagliptin and metformin hydrochloride extended-release tablets may be required until renal function has been confirmed to be normal [see Warnings and Precautions ( 5.1 )] .

Pancreatitis Inform patients that acute pancreatitis has been reported during post-marketing use of saxagliptin. Educate patients that persistent severe abdominal pain, sometimes radiating to the back, which may or may not be accompanied by vomiting, is the hallmark symptom of acute pancreatitis. Instruct patients to promptly discontinue saxagliptin and metformin hydrochloride extended-release tablets and contact their health care provider if persistent severe abdominal pain occurs [see Warnings and Precautions ( 5.2 )].

Heart Failure Inform patients of the signs and symptoms of heart failure. Before initiating saxagliptin and metformin hydrochloride extended-release tablets, ask patients if they have a history of heart failure or other risk factors for heart failure including moderate to severe renal impairment. Instruct patients to contact their health care provider as soon as possible if they experience symptoms of heart failure, including increasing shortness of breath, rapid increase in weight or swelling of the feet [see Warnings and Precautions ( 5.3 )].

Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues Inform patients that hypoglycemia can occur, particularly when insulin or an insulin secretagogue is used in combination with saxagliptin and metformin hydrochloride extended-release tablets. Educate patients about the risks, symptoms and appropriate management of hypoglycemia [see Warnings and Precautions ( 5.5 )]. Hypersensitivity Reactions Patients should be informed that serious allergic (hypersensitivity) reactions, such as angioedema, anaphylaxis, and exfoliative skin conditions, have been reported during post-marketing use of saxagliptin.

If symptoms of these allergic reactions (such as rash, skin flaking or peeling, urticaria, swelling of the skin, or swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing) occur, patients must stop taking saxagliptin and metformin hydrochloride extended-release tablets and seek medical advice promptly [s… [Excerpted — this section continues on DailyMed.]

MEDICATION GUIDE Saxagliptin and Metformin Hydrochloride (sax-a-GLIP-tin and met-FOR-min hye-droe-KLOR-ide) Extended-Release Tablets, for oral use What is the most important information I should know about saxagliptin and metformin hydrochloride extended-release tablets? Serious side effects can happen in people taking saxagliptin and metformin hydrochloride extended-release tablets, including: 1. Lactic acidosis.

Metformin, one of the medicines in saxagliptin and metformin hydrochloride extended-release tablets, can cause a rare but serious condition called lactic acidosis (a build-up of an acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital. Stop taking saxagliptin and metformin hydrochloride extended-release tablets and call your healthcare provider right away or go to the nearest hospital emergency room if you have any of the following symptoms of lactic acidosis: feel very weak or tired you have unusual (not normal) muscle pain you have trouble breathing you have stomach pains, nausea, vomiting or diarrhea have unusual sleepiness or sleep longer than usual feel cold, especially in your arms and legs feel dizzy or lightheaded have a slow or irregular heartbeat Most people who have had lactic acidosis with metformin have other things that, combined with the metformin, led to the lactic acidosis.

Tell your doctor if you have any of the following, because you have a higher chance for getting lactic acidosis with saxagliptin and metformin hydrochloride extended-release tablets if you: have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye have liver problems drink alcohol very often, or drink a lot of alcohol in short-term "binge" drinking get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. Dehydration can also happen when you sweat a lot with activity or exercise and do not drink enough fluids are 65 years of age or older have a genetically inherited disease affecting mitochondria (the energy-producing parts within cells) such as mitochondrial encephalomyopathy with lactic acidosis, and stroke-like episodes (MELAS) syndrome and maternally inherited diabetes and deafness (MIDD). have surgery have a heart attack, severe infection, or stroke The best way to keep from having a problem with lactic acidosis from metformin is to tell your doctor if you have any of the problems in the list above.

Your doctor may decide to stop your saxagliptin and metformin hydrochloride extended-release tablets for a while if you have any of these things. Saxagliptin and metformin hydrochloride extended-release tablets can have other serious side effects. See “What are the possible side effects of saxagliptin and metformin hydrochloride extended-release tablets?

2. Inflammation of the pancreas (pancreatitis) which may be severe and lead to death. Certain medical problems make you more likely to get pancreatitis.

🧬 Pharmacokinetics ~3 min read ▾

12.3Pharmacokinetics Saxagliptin and Metformin Hydrochloride Extended-release Tablets Bioequivalence and food effect of saxagliptin and metformin hydrochloride extended-release tablets was characterized under low calorie diet. The low calorie diet consisted of 324 kcal with meal composition that contained 11.1% protein, 10.5% fat, and 78.4% carbohydrate. The results of bioequivalence studies in healthy subjects demonstrated that saxagliptin and metformin hydrochloride extended-release combination tablets are bioequivalent to coadministration of corresponding doses of saxagliptin (ONGLYZA ® ) and metformin HCl extended-release as individual tablets under fed conditions.

Saxagliptin The pharmacokinetics of saxagliptin and its active metabolite, 5-hydroxy saxagliptin were similar in healthy subjects and in patients with type 2 diabetes mellitus. The C max and AUC values of saxagliptin and its active metabolite increased proportionally in the 2.5 to 400 mg dose range. Following a 5 mg single oral dose of saxagliptin to healthy subjects, the mean plasma AUC values for saxagliptin and its active metabolite were 78 ng•h/mL and 214 ng•h/mL, respectively.

The corresponding plasma C max values were 24 ng/mL and 47 ng/mL, respectively. The average variability (%CV) for AUC and C max for both saxagliptin and its active metabolite was less than 25%. No appreciable accumulation of either saxagliptin or its active metabolite was observed with repeated once-daily dosing at any dose level.

No dose- and time-dependence were observed in the clearance of saxagliptin and its active metabolite over 14 days of once-daily dosing with saxagliptin at doses ranging from 2.5 to 400 mg. Metformin HCl Metformin extended-release C max is achieved with a median value of 7 hours and a range of 4 to 8 hours. At steady state, the AUC and C max are less than dose proportional for metformin extended-release within the range of 500 to 2,000 mg.

After repeated administration of metformin extended-release, metformin did not accumulate in plasma. Metformin is excreted unchanged in the urine and does not undergo hepatic metabolism. Peak plasma levels of metformin extended-release tablets are approximately 20% lower compared to the same dose of metformin immediate-release tablets, however, the extent of absorption (as measured by AUC) is similar between extended-release tablets and immediate-release tablets.

Absorption Saxagliptin The median time to maximum concentration (T max ) following the 5 mg once daily dose was 2 hours for saxagliptin and 4 hours for its active metabolite. Metformin HCl Following a single oral dose of metformin extended-release, C max is achieved with a median value of 7 hours and a range of 4 to 8 hours. Effect of Food Saxagliptin Administration with a high-fat meal resulted in an increase in T max of saxagliptin by approximately 20 minutes as compared to fasted conditions.

There was a 27% increase in the AUC of saxagliptin when given with a meal as compared to fasted conditions. Food has no significant effect on the pharmacokinetics of saxagliptin when administered as saxagliptin and metformin hydrochloride extended-release combination tablets. Metformin HCl Although the extent of metformin absorption (as measured by AUC) from the metformin extended-release tablet increased by approximately 50% when given with food, there was no effect of food on C max and T max of metformin.

Both high and low fat meals had the same effect on the pharmacokinetics of metformin extended-release. Food has no significant effect on the pharmacokinetics of metformin when administered as saxagliptin and metformin hydrochloride extended-release combination tablets. Distribution Saxagliptin The in vitro protein binding of saxagliptin and its active metabolite in human serum is negligible.

Therefore, changes in blood protein levels in various disease states (e.g., renal or hepatic impairment) are not expected to alter the disposition of saxagliptin. Metformin HCl Distr… [Excerpted — this section continues on DailyMed.]

🧬 Pharmacodynamics 131 words ▾

12.2Pharmacodynamics Saxagliptin In patients with type 2 diabetes mellitus, administration of saxagliptin inhibits DPP4 enzyme activity for a 24-hour period. After an oral glucose load or a meal, this DPP4 inhibition resulted in a 2- to 3-fold increase in circulating levels of active GLP-1 and GIP, decreased glucagon concentrations, and increased glucose-dependent insulin secretion from pancreatic beta cells. The rise in insulin and decrease in glucagon were associated with lower fasting glucose concentrations and reduced glucose excursion following an oral glucose load or a meal.

Cardiac Electrophysiology Saxagliptin In a randomized, double-blind, placebo-controlled, 4-way crossover, active comparator trial using moxifloxacin in 40 healthy subjects, saxagliptin was not associated with clinically meaningful prolongation of the QTc interval or heart rate at daily doses up to 40 mg (8 times the MRHD).

14 CLINICAL STUDIES

14.1Glycemic Efficacy Trials The effectiveness of saxagliptin and metformin extended-release has been established in clinical trials of coadministration of oral saxagliptin and metformin HCl immediate-release tablets in adults with type 2 diabetes mellitus inadequately controlled on metformin HCl alone and in treatment-naive patients inadequately controlled on diet and exercise alone. In these two trials, treatment with saxagliptin dosed in the morning plus metformin HCl immediate-release tablets at all doses produced statistically significant improvements in A1C, fasting plasma glucose (FPG), and 2-hour postprandial glucose (PPG) following a standard oral glucose tolerance test (OGTT), compared to control.

Reductions in A1C were seen across subgroups including gender, age, race, and baseline BMI. In these two trials, decrease in body weight in the treatment groups given saxagliptin in combination with metformin HCl immediate-release was similar to that in the groups given metformin HCl immediate-release alone. Saxagliptin plus metformin HCl immediate-release was not associated with significant changes from baseline in fasting serum lipids compared to metformin HCl alone.

The coadministration of saxagliptin and metformin HCl immediate-release tablets has also been evaluated in an active-controlled trial comparing add-on therapy with saxagliptin to glipizide in 858 patients inadequately controlled on metformin HCl alone, in a placebo-controlled trial where a subgroup of 314 patients inadequately controlled on insulin plus metformin HCl received add-on therapy with saxagliptin or placebo, a trial comparing saxagliptin to placebo in 257 patients inadequately controlled on metformin HCl plus a sulfonylurea, and a trial comparing saxagliptin to placebo in 315 patients inadequately controlled on dapagliflozin and metformin HCl.

In a 24-week, double-blind, randomized trial, patients treated with metformin HCl immediate-release 500 mg twice daily for at least 8 weeks were randomized to continued treatment with metformin HCl immediate-release 500 mg twice daily or to metformin HCl extended-release either 1,000 mg once daily or 1,500 mg once daily. The mean change in A1C from baseline to Week 24 was 0.1% (95% confidence interval 0%, 0.3%) for the metformin HCl immediate-release treatment arm, 0.3% (95% confidence interval 0.1%, 0.4%) for the 1,000 mg metformin HCl extended-release treatment arm, and 0.1% (95% confidence interval 0%, 0.3%) for the 1,500 mg metformin HCl extended-release treatment arm.

Results of this trial suggest that patients receiving metformin HCl immediate-release treatment may be safely switched to metformin HCl extended-release once daily at the same total daily dose, up to 2,000 mg once daily. Following a switch from metformin HCl immediate-release to metformin HCl extended-release, glycemic control should be closely monitored and dosage adjustments made accordingly. Saxagliptin Morning and Evening Dosing A 24-week monotherapy trial was conducted to assess a range of dosing regimens for saxagliptin.

Treatment-naive patients with inadequately controlled diabetes (A1C ≥7% to ≤10%) underwent a 2-week, single-blind diet, exercise, and placebo lead-in period. A total of 365 patients were randomized to 2.5 mg every morning, 5 mg every morning, 2.5 mg with possible titration to 5 mg every morning, or 5 mg every evening of saxagliptin, or placebo. Patients who failed to meet specific glycemic goals during the trial were treated with metformin HCl rescue therapy added on to placebo or saxagliptin; the number of patients randomized per treatment group ranged from 71 to 74.

Treatment with either saxagliptin 5 mg every morning or 5 mg every evening provided significant improvements in A1C versus placebo (mean placebo-corrected reductions of −0.4% and −0.3%, respectively). Coadministration of Saxagliptin with Metformin HCl Immediate-Release in Treatment-Naive Patients A total of 1,306 treatment-naive pati… [Excerpted — this section continues on DailyMed.]

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Saxagliptin and Metformin Hydrochloride Extended-release Tablets No animal studies have been conducted with the combined products in saxagliptin and metformin hydrochloride extended-release tablets to evaluate carcinogenesis, mutagenesis, or impairment of fertility. The following data are based on studies with saxagliptin and metformin administered individually. Saxagliptin Carcinogenesis Carcinogenicity was evaluated in 2-year studies conducted in CD-1 mice and Sprague-Dawley rats.

Saxagliptin did not increase the incidence of tumors in mice dosed orally at 50, 250, and 600 mg/kg up to 870-times (males) and 1,165-times (females) the 5 mg/day clinical dose, based on AUC. Saxagliptin did not increase the incidence of tumors in rats dosed orally at 25, 75, 150, and 300 mg/kg up to 355-times (males) and 2,217-times (females) the 5 mg/day clinical dose, based on AUC. Mutagenesis Saxagliptin was not mutagenic or clastogenic in a battery of genotoxicity tests (Ames bacterial mutagenesis, human and rat lymphocyte cytogenetics, rat bone marrow micronucleus and DNA repair assays).

The active metabolite of saxagliptin was not mutagenic in an Ames bacterial assay. Impairment of Fertility Saxagliptin administered to rats had no effect on fertility or the ability to maintain a litter at exposures up to 603-times and 776-times the 5 mg clinical dose in males and females, based on AUC. Metformin HCl Carcinogenesis Long-term carcinogenicity studies have been performed in rats (dosing duration of 104 weeks) and mice (dosing duration of 91 weeks) at doses up to and including 900 mg/kg/day and 1,500 mg/kg/day, respectively.

These doses are both approximately 4 times the maximum recommended human daily dose of 2,000 mg based on body surface area comparisons. No evidence of carcinogenicity with metformin was found in either male or female mice. Similarly, there was no tumorigenic potential observed with metformin in male rats.

There was, however, an increased incidence of benign stromal uterine polyps in female rats treated with 900 mg/kg/day. Mutagenesis There was no evidence of a mutagenic potential of metformin in the following in vitro tests: Ames test (S. typhimurium), gene mutation test (mouse lymphoma cells), or chromosomal aberrations test (human lymphocytes). Results in the in vivo mouse micronucleus test were also negative.

Impairment of Fertility Fertility of male or female rats was unaffected by metformin when administered at doses as high as 600 mg/kg/day, which is approximately 3 times the maximum recommended human daily dose based on body surface area comparisons.

13.2Animal Toxicology and/or Pharmacology Saxagliptin Saxagliptin produced adverse skin changes in the extremities of cynomolgus monkeys (scabs and/or ulceration of tail, digits, scrotum, and/or nose). Skin lesions were reversible within exposure approximately 20-times the 5 mg clinical dose, but in some cases were irreversible and necrotizing at higher exposures. Adverse skin changes were not observed at exposures similar to (1- to 3-times) the 5 mg clinical dose.

Clinical correlates to skin lesions in monkeys have not been observed in human clinical trials of saxagliptin.

Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for this package alone, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
