🩺 Clinical
Glipizide is used along with diet and exercise, and sometimes with other medications, 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). Glipizide is in a class of medications called sulfonylureas. Glipizide lowers blood sugar by causing the pancreas to produce insulin (a natural substance that is needed to break down sugar in the body) and helping the body use insulin efficiently. This medication will only help lower blood sugar in people whose bodies produce insulin naturally. Glipizide is not...

⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Recommended starting dose is 5 mg once daily. Dose adjustment can be made based on the patient’s glycemic control. Maximum recommended dose is 20 mg once daily ( 2.1 ). Administer with breakfast or the first meal of the day ( 2.1 ). For combination therapy with other blood-glucose-lowering agents, initiate the agent at the lowest recommended dose, and observe patients for hypoglycemia ( 2.2 ).
2.1Recommended Dosing Glipizide extended-release tablets should be administered orally with breakfast or the first main meal of the day. The recommended starting dose of glipizide extended-release tablets is 5 mg once daily. Start patients at increased risk for hypoglycemia (e.g. the elderly or patients with hepatic insufficiency) at 2.5 mg [see Use in Specific Population (8.5 , 8.6) ] .
Dosage adjustment can be made based on the patient’s glycemic control. The maximum recommended dose is 20 mg once daily. Patients receiving immediate release glipizide may be switched to glipizide extended-release tablets once daily at the nearest equivalent total daily dose.
2.2Use with Other Glucose Lowering Agents When adding glipizide extended-release tablets to other anti-diabetic drugs, initiate glipizide extended-release tablets at 5 mg once daily. Start patients at increased risk for hypoglycemia at a lower dose. When colesevelam is coadministered with glipizide extended-release tablets, maximum plasma concentration and total exposure to glipizide is reduced.
Therefore, glipizide extended-release tablets should be administered at least 4 hours prior to colesevelam.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Hypoglycemia: May be severe. Ensure proper patient selection, dosing, and instructions, particularly in at-risk populations (e.g., elderly, renally impaired) and when used with other anti-diabetic medications ( 5.1 ). Hemolytic Anemia: Can occur if glucose 6-phosphate dehydrogenase (G6PD) deficient.
Consider a non-sulfonylurea alternative ( 5.2 ). Potential Increased Risk of Cardiovascular Mortality with Sulfonylureas: Inform patient of risks, benefits and treatment alternatives ( 5.3 ). Macrovascular Outcomes: No clinical studies have established conclusive evidence of macrovascular risk reduction with glipizide extended-release tablets or any other antidiabetic drug ( 5.4 ).
5.1Hypoglycemia All sulfonylurea drugs, including glipizide, are capable of producing severe hypoglycemia [see Adverse Reactions (6) ] . Concomitant use of glipizide extended-release tablets with other anti-diabetic medication can increase the risk of hypoglycemia. A lower dose of glipizide extended-release tablets may be required to minimize the risk of hypoglycemia when combining it with other anti-diabetic medications.
Educate patients to recognize and manage hypoglycemia. When initiating and increasing glipizide extended-release tablets in patients who may be predisposed to hypoglycemia (e.g., the elderly, patients with renal impairment, patients on other anti-diabetic medications) start at 2.5 mg. Debilitated or malnourished patients, and those with adrenal, pituitary, or hepatic impairment are particularly susceptible to the hypoglycemic action of anti-diabetic medications.
Hypoglycemia is also more likely to occur when caloric intake is deficient, after severe or prolonged exercise, or when alcohol is ingested. The patient’s ability to concentrate and react may be impaired as a result of hypoglycemia. Early warning symptoms of hypoglycemia may be different or less pronounced in patients with autonomic neuropathy, the elderly, and in patients who are taking beta-adrenergic blocking medications or other sympatholytic agents.
These situations may result in severe hypoglycemia before the patient is aware of the hypoglycemia. These impairments may present a risk in situations where these abilities are especially important, such as driving or operating other machinery. Severe hypoglycemia can lead to unconsciousness or convulsions and may result in temporary or permanent impairment of brain function or death.
5.2Hemolytic Anemia Treatment of patients with glucose 6-phosphate dehydrogenase (G6PD) deficiency with sulfonylurea agents, including glipizide extended-release tablets, can lead to hemolytic anemia. Avoid use of glipizide extended-release tablets in patients with G6PD deficiency. In post marketing reports, hemolytic anemia has also been reported in patients who did not have known G6PD deficiency.
5.3Increased Risk of Cardiovascular Mortality with Sulfonylureas The administration of oral hypoglycemic drugs has been reported to be associated with increased cardiovascular mortality as compared to treatment with diet alone or diet plus insulin. This warning is based on the study conducted by the University Group Diabetes Program (UGDP), a long-term prospective clinical trial designed to evaluate the effectiveness of glucose-lowering drugs in preventing or delaying vascular complications in patients with type 2 diabetes mellitus.
The study involved 823 patients who were randomly assigned to one of four treatment groups. UGDP reported that patients treated for 5 to 8 years with diet plus a fixed dose of tolbutamide (1.5 grams per day) had a rate of cardiovascular mortality approximately 2½ times that of patients treated with diet alone. A significant increase in total mortality was not observed, but the use of tolbutamide was discontinued based on the increase in cardiovascular mortality, thus limiting the opportunity for the study to show an increase in overall mortality.

🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following serious adverse reactions are discussed in more detail below and elsewhere in the labeling: Hypoglycemia [see Warnings and Precautions (5.1) ] Hemolytic anemia [see Warnings and Precautions (5.2) ] Most common adverse reactions (incidence > 3%) are dizziness, diarrhea, nervousness,tremor, hypoglycemia and flatulence ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Rising Pharma Holdings, Inc. at 1-844-874-7464 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. In clinical trials, 580 patients from 31 to 87 years of age received glipizide extended-release tablets in doses from 5 mg to 60 mg in both controlled and open trials. The dosages above 20 mg are not recommended dosages.
In these trials, approximately 180 patients were treated with glipizide extended-release tablets for at least 6 months. Table 1 summarizes the incidence of adverse reactions, other than hypoglycemia, that were reported in pooled double-blind, placebo-controlled trials in ≥3% of glipizide extended-release tablets-treated patients and more commonly than in patients who received placebo. Table 1: Incidence (%) of Adverse Reactions Reported in ≥3% of Patients Treated in Placebo-Controlled Clinical Trials and More Commonly in Patients Treated with glipizide extended-release tablets (Excluding Hypoglycemia) Adverse Effect Glipizide Extended-Release Tablets (%) (N=278) Placebo (%) (N=69) Dizziness 6.8
5.8Diarrhea 5.4
0.0Nervousness 3.6
2.9Tremor 3.6
0.0Flatulence 3.2
1.4Hypoglycemia Of the 580 patients that received glipizide extended-release tablets in clinical trials, 3.4% had hypoglycemia documented by a blood-glucose measurement <60 mg/dL and/or symptoms believed to be associated with hypoglycemia and 2.6% of patients discontinued for this reason. Hypoglycemia was not reported for any placebo patients. Gastrointestinal Reactions In clinical trials, the incidence of gastrointestinal (GI) side effects (nausea, vomiting, constipation, dyspepsia), occurred in less than 3% of glipizide extended-release tablets -treated patients and were more common in glipizide extended-release tablets -treated patients than those receiving placebo.
Dermatologic Reactions In clinical trials, allergic skin reactions, i.e., urticaria occurred in less than 1.5% of treated patients and were more common in glipizide extended-release tablets treated patients than those receiving placebo. These may be transient and may disappear despite continued use of glipizide extended-release tablets; if skin reactions persist, the drug should be discontinued. Laboratory Tests Mild to moderate elevations of ALT, LDH, alkaline phosphatase, BUN and creatinine have been noted.
The relationship of these abnormalities to glipizide is uncertain.
6.2Postmarketing Experience The following adverse reactions have been identified during post approval use of glipizide extended-release tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Abdominal pain Cholestatic and hepatocellular forms of liver injury accompanied by jaundice Leukopenia, agranulocytosis, thrombocytopenia, hemolytic anemia [see Warnings and Precautions (5.2) ] , aplastic anemia, pancytopenia Hepatic porphyria and disulfiram-like reactions Hyponatremia and the syndrome of inappropriate antidiuretic hormone (SIADH) secretion Rash There have been reports of gastrointestinal irritation and gastrointestinal bleeding with use of another drug with this non-dissolvable extended release formulation.

🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Certain medications may affect glucose metabolism, requiring glipizide extended-release tablets dose adjustment and close monitoring of blood glucose (7.1). • Miconazole: Monitor patients closely. Severe hypoglycemia can occur when glipizide tablets and oral miconazole are used concomitantly ( 7.2 , 12.3 ). • Fluconazole: Monitor patients closely. An increase in glipizide tablets AUC was seen after fluconazole administration ( 7.3 , 12.3 ). • Colesevelam: Glipizide extended-release tablets should be administered at least 4 hours prior to colesevelam (7.4 , 12.3 ).
7.1Drugs Affecting Glucose Metabolism A number of medications affect glucose metabolism and may require glipizide extended-release tablets dose adjustment and close monitoring for hypoglycemia or worsening glycemic control. The following are examples of medication that may increase the glucose lowering effect of glipizide extended-release tablets, increase the susceptibility to and/or intensity of hypoglycemia: antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, propoxyphene, salicylates, somatostatin analogs (e.g., octreotide), sulfonamide antibiotics, nonsteroidal anti-inflammatory agents, chloramphenicol, probenecid, coumarins, voriconazole, H2 receptor antagonists, and quinolones.
When these medications are administered to a patient receiving glipizide extended-release tablets, monitor the patient closely for hypoglycemia. When these medications are discontinued from a patient receiving glipizide extended-release tablets, monitor the patient closely for worsening glycemic control. The following are examples of medication that may reduce the glucose-lowering effect of glipizide extended-release tablets, leading to worsening glycemic control: atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), thyroid hormones, phenytoin, nicotinic acid, and calcium channel blocking drugs.
When such drugs are administered to patients receiving glipizide extended-release tablets, monitor the patients closely for worsening glycemic control. When these medications are discontinued from patients receiving glipizide extended-release tablets, monitor the patients closely for hypoglycemia. Alcohol, beta-blockers, clonidine, and reserpine may lead to either potentiation or weakening of the glucose-lowering effect.
Increased frequency of monitoring may be required when glipizide extended-release tablet is co-administered with these drugs. The signs of hypoglycemia may be reduced or absent in patients taking sympatholytic drugs such as beta-blockers, clonidine, guanethidine, and reserpine. Increased frequency of monitoring may be required when glipizide extended-release tablet is co-administered with these drugs.
7.2Miconazole Monitor patients closely for hypoglycemia when glipizide extended-release tablet is co-administered with miconazole. A potential interaction between oral miconazole and oral hypoglycemic agents leading to severe hypoglycemia has been reported [see Clinical Phamacology (12.3 )].
7.3Fluconazole Monitor patients closely for hypoglycemia when glipizide extended-release tablet is co-administered with fluconazole. Concomitant treatment with fluconazole increases plasma concentrations of glipizide, which may lead to hypoglycemia [ see Clinical Pharmacology (12.3 )].
7.4Colesevelam Glipizide extended-release tablets should be administered at least 4 hours prior to the administration of colesevelam. Colesevelam can reduce the maximum plasma concentration and total exposure of glipizide when the two are coadministered [ see Clinical Pharmacology (12.3)].

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Geriatric, Hepatically Impaired Patients: At risk for hypoglycemia with glipizide extended-release tablets. Use caution in dose selection and titration, and monitor closely ( 8.5 , 8.6 ).
8.1Pregnancy Risk Summary Available data from a small number of published studies and postmarketing experience with glipizide extended-release tablets use in pregnancy over decades have not identified any drug associated risks for major birth defects, miscarriage, or adverse maternal outcomes. However, sulfonylureas (including glipizide) cross the placenta and have been associated with neonatal adverse reactions such as hypoglycemia. Therefore, glipizide extended-release tablets should be discontinued at least two weeks before expected delivery ( see Clinical Considerations ).
Poorly controlled diabetes in pregnancy is also associated with risks to the mother and fetus ( see Clinical Considerations ). In animal studies, there were no effects on embryofetal development following administration of glipizide to pregnant rats and rabbits during organogenesis at doses 833 times and 8 times the human dose based on body surface area, respectively. However, increased pup mortality was observed in rats administered glipizide from gestation day 15 throughout lactation at doses 2 times the maximum human dose based on body surface area ( see Data ).
The estimated background risk of major birth defects is 6-10% in women with pre-gestational diabetes with a HbA1c >7 and has been reported to be as high as 20-25% in women with HbA1c >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 2-4% and 15-20%, respectively.
Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Poorly-controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, miscarriage, preterm delivery, stillbirth, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity. Fetal/Neonatal Adverse Reactions Neonates of women with gestational diabetes who are treated with sulfonylureas during pregnancy may be at increased risk for neonatal intensive care admission and may develop respiratory distress, hypoglycemia, birth injury, and be large for gestational age.
Prolonged severe hypoglycemia, lasting 4-10 days, has been reported in neonates born to mothers receiving a sulfonylurea at the time of delivery and has been reported with the use of agents with a prolonged half-life. Observe newborns for symptoms of hypoglycemia and respiratory distress and manage accordingly. Dose adjustments during pregnancy and the postpartum period Due to reports of prolonged severe hypoglycemia in neonates born to mothers receiving a sulfonylurea at the time of delivery, glipizide extended-release tablets should be discontinued at least two weeks before expected delivery ( see Fetal/Neonatal Adverse Reactions ).
Data Animal Data In teratology studies in rats and rabbits, pregnant animals received daily oral doses of glipizide during the period of organogenesis at doses up to 2000 mg/kg/day and 10 mg/kg/day (approximately 833 and 8 times the human dose based on body surface area), respectively. There were no adverse effects on embryo-fetal development at any of the doses tested. In a peri-and postnatal study in pregnant rats, there was a reduced number of pups born alive following administration of glipizide from gestation day 15 throughout lactation through weaning at doses ≥5 mg/kg/day (about 2 times the recommended maximum human dose based on body surface area).
8.2Lactation Risk Summary Breastfed infants of lactating women using glipizide extended-release tablets should be monitored for symptoms of hypoglycemia ( see Clinical Considerations ). Although gl…
🆘 Overdosage ▾
10 OVERDOSAGE Overdosage of sulfonylureas including glipizide can produce severe hypoglycemia. Mild hypoglycemic symptoms without loss of consciousness or neurologic findings should be treated with oral glucose. Severe hypoglycemic reactions with coma, seizure, or other neurological impairment are medical emergencies requiring immediate treatment.
The patient should be treated with glucagon or intravenous glucose. Patients should be closely monitored for a minimum of 24 to 48 hours since hypoglycemia may recur after apparent clinical recovery. Clearance of glipizide from plasma may be prolonged in persons with liver disease.
Because of the extensive protein binding of glipizide, dialysis is unlikely to be of benefit.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Glipizide primarily lowers blood glucose by stimulating the release of insulin from the pancreas, an effect dependent upon functioning beta cells in the pancreatic islets. Sulfonylureas bind to the sulfonylurea receptor in the pancreatic beta-cell plasma membrane, leading to closure of the ATP-sensitive potassium channel, thereby stimulating the release of insulin.
12.2Pharmacodynamics The insulinotropic response to a meal is enhanced with glipizide extended-release tablets administration in diabetic patients. The postprandial insulin and C-peptide responses continue to be enhanced after at least 6 months of treatment. In two randomized, double-blind, dose-response studies comprising a total of 347 patients, there was no significant increase in fasting insulin in all glipizide extended-release tablets-treated patients combined compared to placebo, although minor elevations were observed at some doses.
In studies of glipizide extended-release tablets in subjects with type 2 diabetes mellitus, once daily administration produced reductions in hemoglobin A1c, fasting plasma glucose and postprandial glucose. The relationship between dose and reduction in hemoglobin A1c was not established, however subjects treated with 20 mg had a greater reduction in fasting plasma glucose compared to subjects treated with 5 mg.
12.3Pharmacokinetics Absorption The absolute bioavailability of glipizide was 100% after single oral doses in patients with type 2 diabetes mellitus. Beginning 2 to 3 hours after administration of glipizide extended-release tablets, plasma drug concentrations gradually rise reaching maximum concentrations within 6 to 12 hours after dosing. With subsequent once daily dosing of glipizide extended-release tablets, plasma glipizide concentrations are maintained throughout the 24 hour dosing interval with less peak to trough fluctuation than that observed with twice daily dosing of immediate release glipizide.
The mean relative bioavailability of glipizide in 21 males with type 2 diabetes mellitus after administration of 20 mg glipizide extended-release tablets, compared to immediate release glipizide tablets (10 mg given twice daily), was 90% at steady-state. Steady-state plasma concentrations were achieved by at least the fifth day of dosing with glipizide extended-release tablets in 21 males with type 2 diabetes mellitus and patients younger than 65 years. No accumulation of drug was observed in patients with type 2 diabetes mellitus during chronic dosing with glipizide extended-release tablets.
Administration of glipizide extended-release tablets with food has no effect on the 2 to 3 hour lag time in drug absorption. In a single dose, food effect study in 21 healthy male subjects, the administration of glipizide extended-release tablets immediately before a high fat breakfast resulted in a 40% increase in the glipizide mean C max value, which was significant, but the effect on the AUC was not significant. There was no change in glucose response between the fed and fasting state.
Markedly reduced GI retention times of the glipizide extended-release tablets over prolonged periods (e.g., short bowel syndrome) may influence the pharmacokinetic profile of the drug and potentially result in lower plasma concentrations. In a multiple dose study in 26 males with type 2 diabetes mellitus, the pharmacokinetics of glipizide were linear with glipizide extended-release tablets in that the plasma drug concentrations increased proportionately with dose. In a single dose study in 24 healthy subjects, four 5-mg, two 10-mg, and one 20-mg glipizide extended-release tablets were bioequivalent.
In a separate single dose study in 36 healthy subjects, four 2.5-mg glipizide extended-release tablets were bioequivalent to one 10-mg glipizide extended-release tablets.

📋 Description ▾
11 DESCRIPTION Glipizide extended-release tablets,USP contain glipizide which is an oral sulfonylurea. The Chemical Abstracts name of glipizide is 1-cyclohexyl-3-[[p-[2-(5-methylpyrazinecarboxamido) ethyl] phenyl]sulfonyl]urea. The molecular formula is C 21 H 27 N 5 O 4 S; the molecular weight is 445.55; the structural formula is shown below: Glipizide is a whitish, odorless powder with a pKa of 5.9. It is insoluble in water and alcohols, but soluble in
0.1N NaOH; it is freely soluble in dimethylformamide. Each extended-release film-coated tablet contains 2.63 mg glipizide, USP to provide a 2.5 mg dose. Each extended-release film-coated tablet contains 5.25 mg glipizide, USP to provide a 5 mg dose.
Each extended-release film-coated tablet contains 10.50 mg glipizide, USP to provide a 10 mg dose. Inert ingredients in the 2.5 mg, 5 mg and 10 mg formulations are: cellulose acetate, ferrosoferric oxide, hypromellose, magnesium stearate, polyethylene glycol, polyethylene oxide, propylene glycol, red ferric oxide, shellac, sodium chloride, titanium dioxide. The 2.5 mg tablet also contains: FD&C blue#2, lactose monohydrate and triacetin.
System Components and Performance Glipizide extended-release tablets are similar in appearance to a conventional tablet. It consists, however, of an osmotically active drug core surrounded by a semipermeable membrane. The core itself is divided into two layers: an “active” layer containing the drug, and a “push” layer containing pharmacologically inert (but osmotically active) components.
The membrane surrounding the tablet is permeable to water but not to drug or osmotic excipients. As water from the gastrointestinal tract enters the tablet, pressure increases in the osmotic layer and “pushes” against the drug layer, resulting in the release of drug through a small, laser-drilled orifice in the membrane on the drug side of the tablet. The function of the glipizide extended-release tablets depends upon the existence of an osmotic gradient between the contents of the bi-layer core and fluid in the GI tract.
The biologically inert components of the tablet remain intact during GI transit and are eliminated in the feces as an insoluble shell. structural-formula
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Inform patients of the potential adverse reactions of glipizide extended-release tablets including hypoglycemia. Explain the risks of hypoglycemia, its symptoms and treatment, and conditions that predispose to its development to patients and responsible family members.
Also inform patients about the importance of adhering to dietary instructions, of a regular exercise program, and of regular testing of glycemic control. Inform patients that glipizide extended-release tablets should be swallowed whole. Inform patients that they should not chew, divide or crush tablets and they may occasionally notice in their stool something that looks like a tablet.
In the glipizide extended-release tablets, the medication is contained within a non-dissolvable shell that has been specially designed to slowly release the drug so the body can absorb it. Pregnancy Advise females of reproductive potential to inform their prescriber of a known or suspected pregnancy [see Use in Specific Populations (8.1 )] . Lactation Advise breastfeeding women taking glipizide extended-release tablets to monitor breastfed infants for signs of hypoglycemia (e.g., jitters, cyanosis, hypothermia, excessive sleepiness, poor feeding, seizures) [see Use in Specific Populations (8.2 )].
