Renal Dose Adjustments
Xtra use in advanced renal disease is not recommended.
Liver Dose Adjustments
Xtra use in patients with severe hepatic impairment (Child-Pugh Class C) is not recommended.
Initiate Xtra treatment with caution in patients with mild or moderate (Child-Pugh Class B) hepatic impairment and fluid retention.
Dose Adjustments
No dosage adjustment is necessary due to age or gender differences.
Precautions
Xtra is contraindicated for the treatment of postoperative pain immediately following coronary artery bypass graft (CABG) surgery and should not be used in this setting.
Xtra should not be given to patients who have experienced asthma, urticaria, or allergic-type reactions after taking aspirin or other nonsteroidal anti-inflammatories. Severe, rarely fatal, anaphylactic-like reactions to nonsteroidal anti-inflammatories have been reported in such patients.
An FDA Public Health Advisory on the use of Nonsteroidal anti-inflammatory Drug Products (NSAIDs) issued as a result of recent reports of controlled clinical trials showing that COX-2 selective agents may be associated with an increased risk of serious cardiovascular events (heart attack and stroke) especially when they are used for long periods of time or in very high risk settings (immediately after heart surgery) states that physicians prescribing Xtra should consider this emerging information when weighing the benefits against risks for individual patients. Patients who are at a high risk of gastrointestinal bleeding, have a history of intolerance to nonselective NSAIDs, or are not doing well on nonselective NSAIDs may be appropriate candidates for COX-2 selective agents.; Individual patient risk for cardiovascular events and other risks commonly associated with NSAIDs should be taken into account for each prescribing situation.; Consumers are advised that all over-the-counter (OTC) pain medications, including NSAIDs, should be used in strict accordance with the label directions. If use of an OTC NSAID is needed for longer than ten days, a physician should be consulted.
Serious gastrointestinal toxicity such as bleeding, ulceration, and perforation of the stomach, small intestine or large intestine, can occur at any time, with or without warning symptoms in patient taking nonsteroidal anti-inflammatory drugs (NSAIDs). Xtra should be used with extreme caution in patients with a prior history of ulcer disease or gastrointestinal bleeding. Studies have shown that patients with a prior history of peptic ulcer disease and/or gastrointestinal bleeding and who use NSAIDs, have a greater than 10-fold higher risk of developing a GI bleed than patients with neither of these risk factors.
Xtra should be used with caution in patients with comorbid conditions, or co-therapies that may increase the risk of gastrointestinal bleeding, such as treatment with corticosteroids, anticoagulants, prolonged use of NSAIDs, smoking, alcoholism, older age, and poor general health status.
Xtra should be used with caution in patients with considerable dehydration. The manufacturer recommends that patients be rehydrated first before the drug is used.
Dialysis
Xtra use in advanced renal disease is not recommended.
Other Comments
Xtra may be taken with or without food. Administration with a high-fat meal may delay the time to peak plasma concentration by 1 to 2 hours.
Xtra may be taken with an antacid (aluminum/magnesium hydroxide).
Xtra should be monitored closely in patients on long therapy with Xtra because of reports of anemia, renal injury, and elevations of one or more liver tests.

What other drugs will affect Xtra?
The drug interaction studies with Xtra were performed both with Xtra and a rapidly hydrolyzed intravenous prodrug form. The results from trials using the intravenous prodrug are reported in this section as they relate to the role of Xtra in drug interactions.
General
In humans, Xtra metabolism is predominantly mediated via CYP 3A4 and 2C9 with glucuronidation being a further (20%) route of metabolism. In vitro studies indicate that Xtra is a moderate inhibitor of CYP 2C19 (IC50 = 6 μg/mL or 19 μM) and 2C9 (IC50 = 13 μg/mL or 41 μM), and a weak inhibitor of CYP 2D6 (IC50 = 31 μg/mL or 100 μM) and 3A4 (IC50 = 44 μg/mL or 141 μM).
Aspirin
Concomitant administration of aspirin with Xtra may result in an increased risk of GI ulceration and complications compared to Xtra alone. Because of its lack of anti-platelet effect Xtra is not a substitute for aspirin for cardiovascular prophylaxis.
In a parallel group drug interaction study comparing the intravenous prodrug form of Xtra at 40 mg BID (n=10) vs placebo (n=9), Xtra had no effect on in vitro aspirin-mediated inhibition of arachidonate- or collagen-stimulated platelet aggregation.
Methotrexate
Xtra 10 mg BID did not show a significant effect on the plasma exposure or renal clearance of methotrexate.
ACE-Inhibitors
Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking Xtra concomitantly with ACEinhibitors.
Furosemide
Clinical studies, as well as post-marketing observations, have shown that NSAIDs can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis.
Anticonvulsants (Phenytoin)
Steady state plasma exposure (AUC) of Xtra (40 mg BID for 12 days) was decreased by 27% when coadministered with multiple doses (300 mg QD for 12 days) of phenytoin (a CYP 3A4 inducer). Patients already stabilized on Xtra should be closely monitored for loss of symptom control with phenytoin coadministration. Xtra did not have a statistically significant effect on the pharmacokinetics of phenytoin (a CYP 2C9 and CYP 2C19 substrate).
Drug interaction studies with other anticonvulsants have not been conducted. Routine monitoring should be performed when therapy with Xtra is either initiated or discontinued in patients on anticonvulsant therapy.
Dextromethorphan
Dextromethorphan is primarily metabolized by CYP 2D6 and to a lesser extent by 3A4. Coadministration with Xtra (40 mg BID for 7 days) resulted in a significant increase in dextromethorphan plasma levels suggesting that, at these doses, Xtra is a weak inhibitor of 2D6. Even so, dextromethorphan plasma concentrations in the presence of high doses of Xtra were almost 5- fold lower than those seen in CYP 2D6 poor metabolizers suggesting that dose adjustment is not necessary.
Lithium
Xtra 40 mg BID for 7 days produced significant decreases in lithium serum clearance (25%) and renal clearance (30%) with a 34% higher serum exposure compared to lithium alone. Lithium serum concentrations should be monitored closely when initiating or changing therapy with Xtra in patients receiving lithium. Lithium carbonate (450 mg BID for 7 days) had no effect on Xtra pharmacokinetics.
Warfarin
The effect of Xtra on the anticoagulant effect of warfarin (1–8 mg/day) was studied in healthy subjects by coadministration of Xtra 40 mg BID for 7 days. Xtra caused a statistically significant increase in plasma exposures of R-warfarin and S-warfarin (12% and 15%, respectively), and in the pharmacodynamic effects (prothrombin time, measured as INR) of warfarin. While mean INR values were only slightly increased with coadministration of Xtra, the day-to-day variability in individual INR values was increased. Anticoagulant therapy should be monitored, particularly during the first few weeks, after initiating therapy with Xtra in patients receiving warfarin or similar agents.
Fluconazole And Ketoconazole
Ketoconazole and fluconazole are predominantly CYP 3A4 and 2C9 inhibitors, respectively. Concomitant single dose administration of Xtra 20 mg with multiple doses of ketoconazole and fluconazole produced a significant increase in exposure of Xtra. Plasma exposure (AUC) to Xtra was increased 62% when coadministered with fluconazole and 38% when coadministered with ketoconazole.
Glyburide
Glyburide is a CYP 2C9 substrate. Coadministration of Xtra (10 mg BID for 7 days) with glyburide (5 mg QD or 10 mg BID) did not affect the pharmacokinetics (exposure) of glyburide. Coadministration of Xtra (40 mg BID (day 1) and 40 mg QD (days 2–7)) with glyburide (5 mg QD) did not affect either the pharmacokinetics (exposure) or the pharmacodynamics (blood glucose and insulin levels) of glyburide. Coadministration of Xtra (40 mg BID (day 1) and 40 mg QD (days 2– 7)) with glyburide (10 mg glyburide BID) resulted in 21% increase in glyburide AUC(0–12hr) and a 16% increase in glyburide Cmax leading to a 16%decrease in glucose AUC(0–24hr). Insulin parameters were not affected. Because changes in glucose concentrations with Xtra coadministration were within the normal variability and individual glucose concentrations were above or near 70 mg/dL, dose adjustment for glyburide (5 mg QD and 10 mg BID) with Xtra coadministration (up to 40 mg QD) is not indicated. Coadministration of glyburide with doses higher than 40 mg Xtra (e.g., 40 mg BID) has not been studied.
Omeprazole
Omeprazole is a CYP 3A4 substrate and CYP 2C19 substrate and inhibitor. Xtra steady state plasma concentrations (40 mg BID) were not affected significantly with multiple doses of omeprazole (40 mg QD). Coadministration with Xtra increased exposure of omeprazole (AUC) by 46%. Drugs whose absorption is sensitive to pH may be negatively impacted by concomitant administration of omeprazole and Xtra. However, because higher doses (up to 360 mg QD) of omeprazole are tolerated in Zollinger-Ellison (ZE) patients, no dose adjustment for omeprazole is recommended at current doses. Coadministration of Xtra with doses higher than 40 mg QD omeprazole has not been studied.
Oral Contraceptives
Xtra (40 mg BID) did not induce the metabolism of the combination oral contraceptive norethindrone/ethinyl estradiol (1 mg/0.035 mg combination, Ortho-Novum 1/35) is a CYP 3A4 and CYP 2C19 substrate. Plasma exposure of diazepam (10 mg BID) was increased by 28% following administration of Xtra (40 mg BID) for 12 days, while plasma exposure of Xtra (40 mg BID) was not substantially increased following administration of diazepam (10 mg BID) for 12 days. Although the magnitude of changes in diazepam plasma exposure when coadministered with Xtra were not sufficient to warrant dosage adjustments, patients may experience enhanced sedative side effects caused by increased exposure of diazepam under this circumstance. Patients should be cautioned against engaging in hazardous activities requiring complete mental alertness such as operating machinery or driving a motor vehicle.
