Etodolac is also indicated for the management of pain. Pharmacology Etodolac, an antiinflammatory agent with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain. Mechanism Of Action The antiinflammatory effects of Etodolac Drug Category Anti-inflammatory Agents; Nonsteroidal Antiinflammatory Agents (NSAIDs); ATC:M01AB08 Brand Names/Synonyms CCRIS 3923; CHEMBANK805; Etodolac; Etodolac [Usan:Ban:Inn]; Etodolacetodolicacid; Etodolaco [Inn-Spanish]; Etodolacum [Inn-Latin]; Etodolic Acid; Lodine; Lodine Xl; Ultradol Dosage Forms ER tablets, tablets Absorption Based on mass balance studies, the systemic availability of etodolac from either the tablet or capsule formulation, is at least 80%. Interactions -->Interactions for Etodolac: ACE-inhibitors Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE-inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE-inhibitors. Antacids The concomitant administration of antacids has no apparent effect on the extent of absorption of Lodine. However, antacids can decrease the peak concentration reached by 15% to 20% but have no detectable effect on the time-to-peak. Aspirin When Lodine is administered with aspirin, its protein binding is reduced, although the clearance of free etodolac is not altered. The clinical significance of this interaction is not known; however, as with other NSAIDs, concomitant administration of Lodine and aspirin is not generally recommended because of the potential of increased adverse effects. Cyclosporine, Digoxin, Methotrexate Lodine, like other NSAIDs, through effects on renal prostaglandins, may cause changes in the elimination of these drugs leading to elevated serum levels of cyclosporine, digoxin, methotrexate, and increased toxicity. Nephrotoxicity associated with cyclosporine may also be enhanced. Patients receiving these drugs who are given Lodine, or any other NSAID, and particularly those patients with altered renal function, should be observed for the development of the specific toxicities of these drugs. Diuretics Etodolac has no apparent pharmacokinetic interaction when administered with furosemide or hydrochlorothiazide. Nevertheless, clinical studies, as well as postmarketing observations have shown that Lodine can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy. Glyburide Etodolac has no apparent pharmacokinetic interaction when administered with glyburide. Lithium NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Phenylbutazone Phenylbutazone causes increase (by about 80%) in the free fraction of etodolac. Although in vivo studies have not been done to see if etodolac clearance is changed by coadministration of phenylbutazone, it is not recommended that they be coadministered. Phenytoin Etodolac has no apparent pharmacokinetic interaction when administered with phenytoin. Warfarin The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than that of users of either drug alone. Short-term pharmacokinetic studies have demonstrated that concomitant administration of warfarin and LodineÒ (etodolac capsules and tablets) results in reduced protein binding of warfarin, but there was no change in the clearance of free warfarin. There was no significant difference in the pharmacodynamic effect of warfarin administered alone and warfarin administered with Lodine as measured by prothrombin time. Thus, concomitant therapy with warfarin and Lodine should not require dosage adjustment of either drug. However, caution should be exercised because there have been a few spontaneous reports of prolonged prothrombin times, with or without bleeding, in etodolac-treated patients receiving concomitant warfarin therapy. Drug/Laboratory Test Interactions The urine of patients who take Lodine can give a false-positive reaction for urinary bilirubin (urobilin) due to the presence of phenolic metabolites of etodolac. Diagnostic dip-stick methodology, used to detect ketone bodies in urine, has resulted in false-positive findings in some patients treated with Lodine. Generally, this phenomenon has not been associated with other clinically significant events. No dose relationship has been observed. Lodine treatment is associated with a small decrease in serum uric acid levels. In clinical trials, mean decreases of 1 to 2 mg/dL were observed in arthritic patients receiving etodolac (600 mg to 1000 mg/day) after 4 weeks of therapy. These levels then remained stable for up to 1 year of therapy. --> --> Chemical IUPAC Name 1,8-diethyl-1,3,4,9-tetrahydropyrano-[3,4-b]indole-1-acetic acid Chemical Formula C17H21NO3 Half Life 7.3 +/- 4.0 hours Drug Type Approved Drug # Accession No APRD00067 CAS Registry Number 41340-25-4 |
