🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Diclofenac sodium and misoprostol delayed-release tablets are indicated for treatment of the signs and symptoms of osteoarthritis or rheumatoid arthritis in patients at high risk of developing NSAID-induced gastric and duodenal ulcers and their complications. For a list of factors that may increase the risk of NSAID-induced gastric and duodenal ulcers and their complications [see Warnings and Precautions (5.2) ]. Diclofenac sodium and misoprostol delayed-release tablets are a combination non-steroidal anti-inflammatory and prostaglandin E 1 analog drug indicated for the treatment of signs and symptoms of osteoarthritis (OA) or rheumatoid arthritis (RA) in patients at high risk of developing NSAID-induced gastric and duodenal ulcers and their complications ( 1 )
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION
2.1Important Dosage Information • Carefully consider the potential benefits and risks of diclofenac sodium and misoprostol delayed-release tablets and other treatment options before deciding to use diclofenac sodium and misoprostol delayed-release tablets. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5)]. • After observing the response to initial therapy with diclofenac sodium and misoprostol delayed-release tablets, the dose and frequency should be adjusted to suit an individual patient’s needs. • Diclofenac sodium and misoprostol delayed-release tablets are not recommended for patients who would not receive the appropriate dosage of both active ingredients. • Diclofenac sodium and misoprostol delayed-release tablets, a fixed combination product, are administered as diclofenac sodium and misoprostol delayed-release tablets (50 mg diclofenac sodium/0.2 mg misoprostol) or as diclofenac sodium and misoprostol delayed-release tablets (75 mg diclofenac sodium/0.2 mg misoprostol).
2.2Recommended Dosage in Patients with Osteoarthritis The recommended dosage for the treatment of osteoarthritis for maximal GI mucosal protection is diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg three times a day. For patients who experience intolerance, diclofenac sodium and misoprostol delayed-release tablets 75 mg/0.2 mg two times a day or diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg two times a day can be used, but these dosages are less effective in preventing ulcers.
A daily dosage of diclofenac sodium greater than 150 mg/day is not recommended. Daily doses of the components delivered with these regimens are as follows:
2.3Recommended Dosage in Patients with Rheumatoid Arthritis The recommended dosage for the treatment of rheumatoid arthritis is diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg three or four times a day. For patients who experience intolerance, diclofenac sodium and misoprostol delayed-release tablets 75 mg/0.2 mg two times a day or diclofenac sodium and misoprostol delayed-release tablets 50 mg/0.2 mg two times a day can be used, but are less effective in preventing ulcers. A daily dosage of diclofenac sodium greater than 200 mg/day is not recommended.
Daily doses of the components delivered with these regimens are as follows:
2.4Additional Dosage Recommendations Diclofenac sodium and misoprostol delayed-release tablets contain misoprostol, which provides protection against gastric and duodenal ulcers [see Clinical Studies (14)]. For gastric ulcer prevention, the 200 mcg four and three times a day regimens are therapeutically equivalent, but more protective than the two times a day regimen. For duodenal ulcer prevention, the four times a day regimen is more protective than the three or two times a day regimens.
However, the four times a day regimen is less well tolerated than the three times a day regimen because of usually self-limited diarrhea related to the misoprostol dose [see Adverse Reactions (6.1)], and the two times a day regimen may be better tolerated than three times a day in some patients. Dosages may be individualized using the separate products (misoprostol and diclofenac sodium), after which the patient may be switched to the appropriate diclofenac sodium and misoprostol delayed-release tablets dosage. If clinically indicated, misoprostol co-therapy with diclofenac sodium and misoprostol delayedrelease tablets to optimize the misoprostol dose and/or frequency of administration, may be appropriate.
Do not exceed a total misoprostol dose of 800 mcg/day and do not administer more than 200 mcg of misoprostol at any one time. When concomitant use of CYP2C9 inhibitors is necessary, the maximum total daily dose of diclofenac is 100 mg per day. Do not exceed a dosage of diclofenac sodium and misoprostol delayed-release tablets… [Excerpted — this section continues on DailyMed.]

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Embryo-Fetal Toxicity with NSAIDs: Use of NSAIDs, including diclofenac in women at about 20 weeks gestation and later in pregnancy may cause oligohydramnios/fetal renal dysfunction and premature closure of the fetal ductus arteriosus. (4, 5.1, 8.1) Hepatotoxicity : Inform patients of warning signs and symptoms of hepatotoxicity. Discontinue if abnormal liver tests persist or worsen or if clinical signs and symptoms of liver disease develop ( 5.3 ) Hypertension : Patients taking some antihypertensive medications may have impaired response to these therapies when taking NSAIDs.
Monitor blood pressure ( 5.4 , 7 ) Heart Failure and Edema : Avoid use of diclofenac sodium and misoprostol delayed-release tablets in patients with severe heart failure unless benefits are expected to outweigh risk of worsening heart failure ( 5.5 ) Renal Toxicity : Monitor renal function in patients with renal or hepatic impairment, heart failure, dehydration, or hypovolemia. Avoid use of diclofenac sodium and misoprostol delayed-release tablets in patients with advanced renal disease unless benefits are expected to outweigh risk of worsening renal function ( 5.6 ) Anaphylactic Reactions : Seek emergency help if an anaphylactic reaction occurs ( 5.7 ) Exacerbation of Asthma Related to Aspirin Sensitivity : Diclofenac sodium and misoprostol is contraindicated in patients with aspirin-sensitive asthma.
Monitor patients with preexisting asthma (without aspirin sensitivity) ( 5.8 ) Serious Skin Reactions : Discontinue diclofenac sodium and misoprostol delayed-release tablets at first appearance of skin rash or other signs of hypersensitivity ( 5.9 ) Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS): Discontinue and evaluate clinically. (5.11) Hematologic Toxicity : Monitor hemoglobin or hematocrit in patients with any signs or symptoms of anemia ( 5.11 , 7 )
5.1Uterine Rupture, Abortion, Premature Birth, or Birth Defects with Misoprostol and Embryo-Fetal Toxicity with NSAIDs Misoprostol Administration of misoprostol, a component of diclofenac sodium and misoprostol delayed-release tablets, to pregnant women can cause uterine rupture, abortion, premature birth, or birth defects. Uterine rupture has occurred when misoprostol was administered to pregnant women to induce labor or an abortion. Diclofenac sodium and misoprostol delayed-release tablets are contraindicated in pregnant women.
Diclofenac sodium and misoprostol delayed-release tablets are not recommended in women of childbearing potential. Patients must be advised of the abortifacient property and warned not to give the drug to others [see Use in Specific Populations (8.1)]. If diclofenac sodium and misoprostol delayed-release tablets are prescribed, verify the pregnancy status of females of reproductive potential prior to initiation of treatment and advise the use effective contraception during treatment with diclofenac sodium and misoprostol delayed-release tablets [see Use in Specific Populations (8.3)].
Diclofenac Premature Closure of Fetal Ductus Arteriosus NSAIDs, including diclofenac, a component of diclofenac sodium and misoprostol delayed-release tablets, increase the risk of premature closure of the fetal ductus arteriosus at about 30 weeks of gestation and later. Oligohydramnios/Neonatal Renal Impairment Use of NSAIDs, including diclofenac, at about 20 weeks gestation or later in pregnancy may cause fetal renal dysfunction leading to oligohydramnios and, in some cases, neonatal renal impairment. These adverse outcomes are seen, on average, after days to weeks of treatment, although oligohydramnios has been infrequently reported as soon as 48 hours after NSAID initiation.
Oligohydramnios is often, but not always, reversible with treatment discontinuation. Complications of prolonged oligohydramnios may, for example, include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures… [Excerpted — this section continues on DailyMed.]

6 ADVERSE REACTIONS The following adverse reactions are discussed in greater detail in other sections of the labeling: Cardiovascular Thrombotic Events [see Warnings and Precautions (5.1) ] GI Bleeding, Ulceration and Perforation [see Warnings and Precautions (5.2) ] Hepatotoxicity [see Warnings and Precautions (5.3) ] Hypertension [see Warnings and Precautions (5.4) ] Heart Failure and Edema [see Warnings and Precautions (5.5) ] Renal Toxicity and Hyperkalemia [see Warnings and Precautions (5.6) ] Anaphylactic Reactions [see Warnings and Precautions (5.7) ] Serious Skin Reactions [see Warnings and Precautions (5.9) ] Hematologic Toxicity [see Warnings and Precautions (5.11) ] Most common adverse reactions (incidence greater than 2% from clinical trials) are: abdominal pain, diarrhea, dyspepsia, nausea, flatulence, gastritis, vomiting, constipation, headache, dizziness, alanine aminotransferase increased, hematocrit decreased ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AvKARE 1-855-361-3993 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. Adverse reaction information for diclofenac sodium and misoprostol is derived from Phase III multinational controlled clinical trials in over 2,000 patients receiving diclofenac sodium and misoprostol delayed-release tablets, 50 mg/0.2 mg or diclofenac sodium and misoprostol delayed-release tablets, 75 mg/0.2 mg, as well as from blinded, controlled trials of diclofenac delayed-release tablets and misoprostol tablets.
Gastrointestinal GI disorders had the highest reported incidence of adverse events for patients receiving diclofenac sodium and misoprostol. These events were generally minor, but led to discontinuation of therapy in 9% of patients on diclofenac sodium and misoprostol and 5% of patients on diclofenac. For GI ulcer rates, [see Clinical Studies (14) ] .
GI disorder Diclofenac Sodium and Misoprostol Diclofenac Abdominal pain 21% 15% Diarrhea 19% 11% Dyspepsia 14% 11% Nausea 11% 6% Flatulence 9% 4% Diclofenac sodium and misoprostol can cause more abdominal pain, diarrhea, and other GI symptoms than diclofenac alone. Diarrhea and abdominal pain developed early in the course of therapy, and were usually self-limited (resolved after 2 to 7 days). Rare instances of profound diarrhea leading to severe dehydration have been reported in patients receiving misoprostol.
Patients with an underlying condition such as inflammatory bowel disease, or those in whom dehydration, were it to occur, would be dangerous, should be monitored carefully if diclofenac sodium and misoprostol is prescribed. The incidence of diarrhea can be minimized by administering diclofenac sodium and misoprostol with food and by avoiding coadministration with magnesium-containing antacids. Gynecological Gynecological disorders previously reported with misoprostol use have also been reported for women receiving diclofenac sodium and misoprostol (see below).
Postmenopausal vaginal bleeding may be related to administration of diclofenac sodium and misoprostol. If it occurs, diagnostic workup should be undertaken to rule out gynecological pathology [see Boxed Warnings , Contraindications (4) and Warnings and Precautions (5) ] . Other adverse experiences reported occasionally with diclofenac sodium and misoprostol, diclofenac or other NSAIDs, or misoprostol are: Body as a whole: asthenia, fatigue, malaise.
Central and peripheral nervous system: dizziness, drowsiness, headache, insomnia, paresthesia, vertigo. Digestive: anorexia, appetite changes, constipation, dry mouth, dysphagia, esophageal ulceration, oesophagitis, eructation, gastritis, gastroesophageal reflux, GI neoplasm benign, peptic ulcer, tenesmus, vomiting.

8 USE IN SPECIFIC POPULATIONS Infertility : NSAIDs are associated with reversible infertility. Consider withdrawal of diclofenac sodium and misoprostol in women who have difficulties conceiving ( 8.3 )
8.1Pregnancy Risk Summary Diclofenac sodium and misoprostol is contraindicated in pregnant women [see Contraindications (4) ] . There are no adequate and well-controlled studies of diclofenac sodium and misoprostol in pregnant women; however, there is information available about the active drug components of diclofenac sodium and misoprostol delayed-release tablets, misoprostol and diclofenac sodium. Administration of misoprostol to pregnant women can cause abortion, premature birth, or birth defects.
Congenital anomalies sometimes associated with fetal death have been reported subsequent to the unsuccessful use of misoprostol as an abortifacient, but the drug’s teratogenic mechanism has not been demonstrated. Use of NSAIDS, including diclofenac, during the third trimester of pregnancy increases the risk of premature closure of fetal ductus arteriosus [see Data ] . There are clinical considerations when misoprostol and diclofenac are used in pregnant women [see Clinical Considerations ] .
In reproduction studies with pregnant rabbits, there were no skeletal or visceral malformations when the combination of diclofenac sodium and misoprostol was administered during organogenesis at doses less than the maximum recommended human doses (MRHD); however, embryotoxicity was observed at this exposure [see Data ] . Based on animal data, prostaglandins have been shown to have an important role in endometrial vascular permeability, blastocyst implantation, and decidualization. In animal studies, administration of prostaglandin synthesis inhibitors such as diclofenac, resulted in increased pre- and post-implantation loss.
If a woman becomes pregnant while taking diclofenac sodium and misoprostol, discontinue the drug and advise the woman of the potential risks to her and to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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 Maternal Adverse Reactions Misoprostol may produce uterine contractions, uterine bleeding, and expulsion of the products of conception. Misoprostol has been used to ripen the cervix, to induce labor, and to treat postpartum hemorrhage, outside of its approved indication. A major adverse effect of these uses is hyperstimulation of the uterus.
Uterine rupture, amniotic fluid embolism, severe bleeding, shock, and maternal death have been reported when misoprostol was administered to pregnant women to induce labor to induce abortion beyond the eight week of pregnancy. Higher doses of misoprostol, including the 100 mcg tablet, may increase the risk of complications from uterine hyperstimulation. Diclofenac sodium and misoprostol delayed-release tablets, which contains 200 mcg of misoprostol, is likely to have a greater risk of uterine hyperstimulation than the 100 mcg tablet of misoprostol.
Abortions caused by misoprostol may be incomplete. Cases of amniotic fluid embolism, which resulted in maternal and fetal death, have been reported with use of misoprostol during pregnancy. Severe vaginal bleeding, retained placenta, shock, and pelvic pain have also been reported.
These women were administered misoprostol vaginally and/or orally over a range of doses. If a woman is or becomes pregnant while taking this drug, the drug should be discontinued and the patient apprised of the potential hazard to the fetus. Diclofenac sodium and misoprostol is contraindicated in pregnant women [see Contraindications (4) ] .
Fetal/Neonatal Adverse Reactions Misoprostol Misoprostol may endanger pregnancy (may cause abortion) and thereby cause harm to the fetus when administered to a pregnant woman. Use of misopros… [Excerpted — this section continues on DailyMed.]

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of diclofenac sodium and misoprostol in pediatric patients have not been established.
🧓 Geriatric Use ▾
8.5Geriatric Use Geriatric patients (those 65 years of age and older), compared to younger adult patients, are at greater risk for NSAID-associated serious cardiovascular, gastrointestinal, and/or renal adverse reactions [see Warnings and Precautions (5.2, 5.3, 5.7)]. In addition, the risk of diclofenac-associated adverse reactions may be greater in geriatric patients with renal impairment or those taking concomitant ACE inhibitors or ARBs [see Drug Interactions (7) and Use in Specific Populations (8.6)]. Avoid use of diclofenac sodium and misoprostol delayed-release tablets in geriatric patients with cardiovascular and/or renal risk factors.
If use cannot be avoided, use the lowest recommended dosage for the shortest duration and monitor for cardiac and renal adverse reactions [see Dosage and Administration (2.1)]. Monitor renal function in geriatric patients during treatment with diclofenac sodium and misoprostol delayed-release tablets, especially in patients with concomitant use of ACE inhibitors or ARBs. Of the 2,184 patients in clinical studies with diclofenac sodium and misoprostol delayed-release tablets, 557 (25.5%) were 65 years of age and over.
No overall differences in effectiveness were observed between these patients and younger adult patients, and other reported clinical experience has not identified differences in effectiveness between geriatric patients and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out. No clinically meaningful differences in the pharmacokinetics of diclofenac and misoprostol were observed in geriatric patients compared to younger adult patients [see Clinical Pharmacology (12.3)].
🆘 Overdosage ▾
10 OVERDOSAGE Manage patients with symptomatic and supportive care following an acute NSAID overdosage. There are no specific antidotes. It is advisable to contact a poison control center (1-800-222-1222) to determine the latest recommendations because strategies for the management of overdose are continually evolving.
The toxic dose of diclofenac sodium and misoprostol delayed-release tablets has not been determined. However, signs of overdosage from the components of the product have been described. Diclofenac Symptoms following acute NSAID overdosages have been typically limited to lethargy, drowsiness, nausea, vomiting, and epigastric pain, which have been generally reversible with supportive care.
Gastrointestinal bleeding has occurred. Hypertension, acute renal failure, respiratory depression, and coma have occurred, but were rare [see Warnings and Precautions (5.2, 5.3, 5.5, 5.7)]. Clinical signs that may suggest diclofenac sodium overdose include GI complaints, confusion, drowsiness, or general hypotonia.
If gastric decontamination may be potentially beneficial to the patient, e.g., short time since ingestion or a large overdosage (5 to 10 times the recommended dosage), consider emesis and/or activated charcoal (60 grams to 100 grams in adults, 1 gram to 2 grams per kg of body weight in pediatric patients) and/or an osmotic cathartic in symptomatic patients. Forced diuresis, alkalinization of urine, hemodialysis, or hemoperfusion may not be useful due to high protein binding. Misoprostol The toxic dose of misoprostol in humans has not been determined.
Cumulative total daily doses of 1600 mcg have been tolerated, with only symptoms of GI discomfort being reported. Clinical signs that may indicate an overdose are sedation, tremor, convulsions, dyspnea, abdominal pain, diarrhea, fever, palpitations, hypotension, or bradycardia. Diclofenac Sodium and Misoprostol Delayed-Release Tablets Symptoms of acute overdosage with diclofenac sodium and misoprostol delayedrelease tablets should be treated with supportive and symptomatic therapy.
There are no specific antidotes. In case of acute overdosage, emesisis and/or gastric lavage may be considered dependent upon amount ingested and time since ingestion. The use of oral activated charcoal may help to reduce the absorption of diclofenac sodium and misoprostol.
Induced diuresis may be beneficial because diclofenac sodium and misoprostol metabolites are excreted in the urine. The effect of dialysis or hemoperfusion on the elimination of diclofenac sodium (99% protein bound) and misoprostol acid remains unproven.

12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Diclofenac/misoprostol is a combination product containing diclofenac, a nonsteroidal anti-inflammatory drug (NSAID) with analgesic, anti-inflammatory and antipyretic properties, and misoprostol, a GI mucosal protective prostaglandin E 1 analog. Diclofenac The mechanism of action of diclofenac, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2). Diclofenac is a potent inhibitor of prostaglandin (PG) synthesis in vitro .
Diclofenac concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation.
Because diclofenac is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues. Misoprostol Misoprostol is a synthetic prostaglandin E 1 analog with gastric antisecretory and mucosal protective properties. NSAIDs inhibit prostaglandin synthesis.
A deficiency of prostaglandins within the gastric and duodenal mucosa may lead to diminishing bicarbonate and mucus secretion and may contribute to the mucosal damage caused by NSAIDs. Misoprostol can increase bicarbonate and mucus production, but it has been shown at doses 200 mcg and above that are also antisecretory. It is therefore not possible to differentiate whether the ability of misoprostol to reduce the risk of gastric and duodenal ulcers is the result of its antisecretory effect, its mucosal protective effect, or both.
In vitro studies on canine parietal cells using titrated misoprostol acid as the ligand have led to the identification and characterization of specific prostaglandin receptors. Receptor binding is saturable, reversible, and stereo-specific. The sites have a high affinity for misoprostol, for its acid metabolite, and for other E type prostaglandins, but not for F or I prostaglandins and other unrelated compounds, such as histamine or cimetidine.
Receptor-site affinity for misoprostol correlates well with an indirect index of antisecretory activity. It is likely that these specific receptors allow misoprostol taken with food to be effective topically, despite the lower serum concentrations attained. Misoprostol, over the range of 50 to 200 mcg, inhibits basal and nocturnal gastric acid secretion, and acid secretion in response to a variety of stimuli, including meals, histamine, pentagastrin, and coffee.
Activity is apparent 30 minutes after oral administration and persists for at least 3 hours. In general, the effects of 50 mcg were modest and shorter-lived, and only the 200 mcg dose had substantial effects on nocturnal secretion or on histamine- and meal-stimulated secretion. Misoprostol also produces a moderate decrease in pepsin concentration during basal conditions, but not during histamine stimulation.
It has no significant effect on fasting or postprandial gastrin nor intrinsic factor output.
12.3Pharmacokinetics General pharmacokinetic characteristics The pharmacokinetic profiles of diclofenac and misoprostol administered as the fixed combination diclofenac sodium and misoprostol delayed-release tablets, 50 mg/0.2 mg or diclofenac sodium and misoprostol delayed-release tablets, 75 mg/0.2 mg are similar to the profiles when the two drugs are administered as separate tablets (see Table 2). No pharmacokinetic interaction between the two drugs has been observed following multiple dosing. The diclofenac total exposure [area under the curve (AUC)] is dose-proportional within the range of 25 mg to 150 mg.
Approximately dose-proportional increase in misoprostol exposure was also observed within the range of 200 to 400 mcg. Neither diclofenac nor misoprostol accumulated in plasma following repeated doses of diclofenac sodium and misoprostol given every 12 hours under fasted conditions.

Medication Guide for Diclofenac Sodium (dye kloe’ fen ak soe’ dee um) and Misoprostol (mye’ soe pros’ tol) Delayed-Release Tablets for oral use What is the most important information I should know about diclofenac sodium and misoprostol delayed-release tablets? Diclofenac sodium and misoprostol delayed-release tablets contain diclofenac (a nonsteroidal anti-inflammatory drug (NSAID)) and misoprostol, and can cause uterus to tear (uterine rupture), abortion, premature birth, or birth defects. The risk of uterine rupture increases as your pregnancy advances, if you have given birth to 5 or more children, and if you have had surgery on the uterus, such as a cesarean delivery.
Do not take diclofenac sodium and misoprostol delayed-release tablets if you are pregnant. • Tell your healthcare provider if you become pregnant or think you may be pregnant during treatment with diclofenac sodium and misoprostol delayedrelease tablets. If you are able to become pregnant, your healthcare provider should do a pregnancy test before you start treatment with diclofenac sodium and misoprostol delayed-release tablets. Females who are able to become pregnant should use an effective form of birth control (contraception) during treatment with diclofenac sodium and misoprostol delayed-release tablets.
What is the most important information I should know about medicines containing Nonsteroidal Anti-inflammatory Drugs (NSAIDs)? NSAIDs can cause serious side effects, including: • Increased risk of a heart attack or stroke that can lead to death. This risk may happen early in treatment and may increase: • with increasing doses of NSAIDs • with longer use of NSAIDs Do not take NSAID containing medicines right before or after a heart surgery called a “coronary artery bypass graft (CABG)." Avoid taking NSAID containing medicines after a recent heart attack, unless your healthcare provider tells you to.
You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack. • Increased risk of bleeding, ulcers, and tears (perforation) of the esophagus(tube leading from the mouth to the stomach), stomach and intestines: • anytime during use • without warning symptoms • that may cause death NSAID containing medicines should only be used: ○ exactly as prescribed ○ at the lowest dose possible for your treatment ○ for the shortest time needed What is diclofenac sodium and misoprostol delayed-release tablets?
Diclofenac sodium and misoprostol delayed-release tablets contains 2 medicines: 1. Diclofenac is a non-steroidal anti-inflammatory drug (NSAID). See “What is the most important information I should know about medicines called Nonsteroidal Anti-inflammatory Drugs (NSAIDs)?
2. Misoprostol is a medicine used to protect the lining of the esophagus, stomach and intestines while taking diclofenac. Diclofenac sodium and misoprostol delayed-release tablets is a prescription medicine used to treat: • symptoms of osteoarthritis or rheumatoid arthritis in adults at high risk of developing stomach (gastric) and intestinal (duodenal) ulcers while taking NSAIDs.
It is not known if diclofenac sodium and misoprostol delayed-release tablets are safe and effective for use in children. What are NSAIDs? NSAIDs are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as different types of arthritis, menstrual cramps, and other types of short-term pain.

🧬 Pharmacokinetics ▾
12.3Pharmacokinetics General pharmacokinetic characteristics The pharmacokinetic profiles of diclofenac and misoprostol administered as the fixed combination diclofenac sodium and misoprostol delayed-release tablets, 50 mg/0.2 mg or diclofenac sodium and misoprostol delayed-release tablets, 75 mg/0.2 mg are similar to the profiles when the two drugs are administered as separate tablets (see Table 2). No pharmacokinetic interaction between the two drugs has been observed following multiple dosing. The diclofenac total exposure [area under the curve (AUC)] is dose-proportional within the range of 25 mg to 150 mg.
Approximately dose-proportional increase in misoprostol exposure was also observed within the range of 200 to 400 mcg. Neither diclofenac nor misoprostol accumulated in plasma following repeated doses of diclofenac sodium and misoprostol given every 12 hours under fasted conditions. Absorption Diclofenac: Diclofenac is completely absorbed from the GI tract after oral administration under fasted condition, and peak plasma levels are achieved in 2 hours (range 1 to 4 hours), and the area under the plasma concentration curve (AUC) is dose-proportional within the range of 25 mg to 150 mg.
Peak plasma levels are less than dose-proportional and are approximately 1.5 and 2.0 mcg/mL for 50 mg and 75 mg doses, respectively. The diclofenac in diclofenac sodium and misoprostol is in a pharmaceutical formulation that resists dissolution in the low pH of gastric fluid but allows a rapid release of drug in the higher pH environment of the duodenum. Only 50% of the absorbed dose is systemically available due to first pass metabolism (i.e., oral bioavailability is 50%).
Misoprostol: Misoprostol is rapidly absorbed following oral administration of diclofenac sodium and misoprostol , and misoprostol acid (active metabolite) reaches a maximum plasma concentration in approximately 20 minutes. Maximum plasma concentrations of misoprostol acid are diminished when the dose is taken with food, and total availability of misoprostol acid is reduced by use of concomitant antacid. Clinical trials were conducted with concomitant antacid; this effect does not appear to be clinically important.
Food decreases the multiple-dose bioavailability profile of diclofenac sodium and misoprostol delayed-release tablets, 50 mg/0.2 mg and diclofenac sodium and misoprostol delayed-release tablets, 75 mg/0.2 mg. Distribution Diclofenac: The volume of distribution of diclofenac is approximately
0.55L/kg. More than 99% of diclofenac is bound to plasma albumin. Misoprostol: The plasma protein binding of misoprostol acid is less than 90% and is concentration-independent in the therapeutic range.
After a single oral dose of misoprostol to nursing mothers, misoprostol acid was excreted in breast milk. The maximum concentration of misoprostol acid in expressed breast milk was achieved within 1 hour after dosing and was 7.6 pg/mL (CV 37%) and 20.9 pg/mL (CV 77%) after single 200 mcg and 600 mcg misoprostol administration, respectively. The misoprostol acid concentrations in breast milk declined to less than 1 pg/mL at 5 hours post-dose.
These data may not reflect drug level in mature milk and in a daily dosing regimen for osteoarthritis or rheumatoid arthritis. Metabolism Diclofenac: Diclofenac metabolism is predominantly mediated via CYP2C9 in the liver. Five metabolites (4'hydroxy-, 5-hydroxy-, 3'-hydroxy-, 4',5-dihydroxy- and 3'-hydroxy-4'-methoxy diclofenac) have been identified.
The major metabolite (4'-hydroxy-diclofenac) has very weak pharmacologic activity. Both diclofenac and its oxidative metabolites undergo glucuronidation or sulfation followed by biliary excretion. Acylglucuronidation mediated by UGT2B7 and oxidation mediated by CYP2C8 may also play a role in diclofenac metabolism.
CYP3A4 is responsible for the formation of minor metabolites, 5-hydroxy and 3'-hydroxy-diclofenac. Misoprostol: It undergoes rapid and extensive metabolism to its biologically ac… [Excerpted — this section continues on DailyMed.]
🔬 Clinical Studies ▾
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. Adverse reaction information for diclofenac sodium and misoprostol is derived from Phase III multinational controlled clinical trials in over 2,000 patients receiving diclofenac sodium and misoprostol delayed-release tablets, 50 mg/0.2 mg or diclofenac sodium and misoprostol delayed-release tablets, 75 mg/0.2 mg, as well as from blinded, controlled trials of diclofenac delayed-release tablets and misoprostol tablets.
Gastrointestinal GI disorders had the highest reported incidence of adverse events for patients receiving diclofenac sodium and misoprostol. These events were generally minor, but led to discontinuation of therapy in 9% of patients on diclofenac sodium and misoprostol and 5% of patients on diclofenac. For GI ulcer rates, [see Clinical Studies (14) ] .
GI disorder Diclofenac Sodium and Misoprostol Diclofenac Abdominal pain 21% 15% Diarrhea 19% 11% Dyspepsia 14% 11% Nausea 11% 6% Flatulence 9% 4% Diclofenac sodium and misoprostol can cause more abdominal pain, diarrhea, and other GI symptoms than diclofenac alone. Diarrhea and abdominal pain developed early in the course of therapy, and were usually self-limited (resolved after 2 to 7 days). Rare instances of profound diarrhea leading to severe dehydration have been reported in patients receiving misoprostol.
Patients with an underlying condition such as inflammatory bowel disease, or those in whom dehydration, were it to occur, would be dangerous, should be monitored carefully if diclofenac sodium and misoprostol is prescribed. The incidence of diarrhea can be minimized by administering diclofenac sodium and misoprostol with food and by avoiding coadministration with magnesium-containing antacids. Gynecological Gynecological disorders previously reported with misoprostol use have also been reported for women receiving diclofenac sodium and misoprostol (see below).
Postmenopausal vaginal bleeding may be related to administration of diclofenac sodium and misoprostol. If it occurs, diagnostic workup should be undertaken to rule out gynecological pathology [see Boxed Warnings , Contraindications (4) and Warnings and Precautions (5) ] . Other adverse experiences reported occasionally with diclofenac sodium and misoprostol, diclofenac or other NSAIDs, or misoprostol are: Body as a whole: asthenia, fatigue, malaise.
Central and peripheral nervous system: dizziness, drowsiness, headache, insomnia, paresthesia, vertigo. Digestive: anorexia, appetite changes, constipation, dry mouth, dysphagia, esophageal ulceration, oesophagitis, eructation, gastritis, gastroesophageal reflux, GI neoplasm benign, peptic ulcer, tenesmus, vomiting. Female reproductive disorders: breast pain, dysmenorrhea, menstrual disorder, menorrhagia, vaginal hemorrhage.
Hemic and lymphatic system: epistaxis, leukopenia, melena, purpura, decreased hematocrit. Metabolic and nutritional: alanine aminotransferase increased, alkaline phosphatase increased, aspartate aminotransferase increased, dehydration, hyponatremia. Musculoskeletal system: arthralgia, myalgia.
Psychiatric: anxiety, concentration impaired, depression, irritability. Respiratory system: asthma, coughing, hyperventilation. Skin and appendages: alopecia, eczema, pemphigoid reaction, photosensitivity, sweating increased, pruritus.
Special senses: taste perversion, tinnitus. Renal and urinary disorders: dysuria, nocturia, polyuria, proteinuria, urinary tract infection. Vision: diplopia.

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis Long-term animal studies to evaluate the potential for carcinogenesis and animal studies to evaluate the effects on fertility have been performed with each component of diclofenac sodium and misoprostol delayed-release tablets given alone. In a 24 month rat carcinogenicity study, misoprostol administered orally at doses up to 2.4 mg/kg/day (14.4 mg/m2/day, 24 times the MRHD of 0.6 mg/m2/day) was not tumorigenic. In a 21-month mouse carcinogenicity study, misoprostol administered orally at doses up to 16 mg/kg/day (48 mg/m2/day), 80 times the MRHD based on body surface area, was not tumorigenic.
In a 24-month rat carcinogenicity study, diclofenac sodium administered orally at up to 2 mg/kg/day (12 mg/m2/day) was not tumorigenic. In a 24-month mouse carcinogenicity study, oral diclofenac sodium at doses up to 0.3 mg/kg/day (0.9 mg/m2/day, 0.006 times the MRHD based on body surface area) in males and 1 mg/kg/day (3 mg/m2/day, 0.02 times the MRHD based on body surface area) in females was not tumorigenic. Mutagenesis Diclofenac sodium and misoprostol combination in 250:1 ratio was not genotoxic in the Ames test, the Chinese hamster ovary cell (CHO/HGPRT) forward mutation test, the rat lymphocyte chromosome aberration test, or the mouse bone marrow micronucleus test.
Impairment of Fertility The effects of diclofenac sodium and misoprostol on male or female fertility have not been studied in animals; however, there are data with diclofenac sodium and misoprostol given alone. Misoprostol, when administered to male and female breeding rats in an oral dose range of 0.1 to 10 mg/kg/day (0.6 to 60 mg/m2/day, 1 to 100 times the MRHD based on body surface area) produced dose-related pre- and post-implantation losses and a significant decrease in the number of live pups born at the highest dose (60 mg/m2/day, 100 times the MRHD based on body surface area).
Diclofenac sodium at oral doses up to 4 mg/kg/day (24 mg/m2/day, 0.16 times the MRHD based on body surface area) was found to have no effect on fertility and reproductive performance of male and female rats.
13.2Animal Toxicology A reversible increase in the number of normal surface gastric epithelial cells occurred in the dog, rat, and mouse during long-term toxicology studies with misoprostol. No such increase has been observed in humans administered misoprostol for up to 1 year. An apparent response of the female mouse to misoprostol in long-term studies at 100 to 1000 times the human dose was hyperostosis, mainly of the medulla of sternebrae.
Hyperostosis did not occur in long-term studies in the dog and rat and has not been seen in humans treated with misoprostol.
