Oxaprozin, the potassium salt of oxaprozin, is a nonsteroidal anti-inflammatory drug (NSAID), which dissociates into the active moiety oxaprozin in vivo. Oxaprozin has analgesic, anti-inflammatory, and antipyretic properties.The mechanism of action of Oxaprozin, like that of other NSAIDs, is not completely understood but involves inhibition of cyclooxygenase (COX-1 and COX-2).Oxaprozin is a potent inhibitor of prostaglandin synthesis in vitro. Oxaprozin 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 oxaprozin potassium is an inhibitor of prostaglandin synthesis, its mode of action may be due to a decrease of prostaglandins in peripheral tissues.
Increased risk of salicylate toxicity with aspirin. May increase effects of oral anticoagulants. May reduce effects of β-blockers, diuretics and other antihypertensive agents. May increase risk of methotrexate and lithium toxicity.
Common side effects are depression, sedation, somnolence, confusion, disturbance of sleep, weakness, malaise; rash, prutitus, urticaria, photosensitivity; abdominal pain/distress, anorexia, flatulence, vomiting, constipation, diarrhoea, dyspepsia, nausea, peptic ulcer and/or GI bleeding, abnormalities in LFTs, stomatitis, haemorrhoidal or rectal bleeding; tinnitus; dysuria or frequency; oedema, BP changes; haematuria, renal insufficiency, decreased menstrual flow; anaemia, thrombocytopenia, leukopenia, ecchymoses; wt gain/loss; blurred vision, conjunctivitis.The following adverse reactions may occur: Cardiovascular Thrombotic Events GI Bleeding, Ulceration and Perforation Hepatotoxicity Hypertension Heart Failure and Edema Renal Toxicity and Hyperkalemia Anaphylactic Reactions Serious Skin Reactions Hematologic Toxicity
Symptoms: Acute renal failure, vomiting, drowsiness, leukocytosis. Management: Supportive and symptomatic. Multiple admin of charcoal may be required to reduce potential for delayed toxicities.
Pregnancy categaory: C, D (in 3rd trimester or near delivery)
Be alert for ulceration and bleeding in patients treated chronically. History of serious GI events, alcoholism, smoking, other factors known to be associated with peptic ulcer. Elderly or debilitated patients. Uncompensated cardiac failure, history of hypertension, cardiac decompensation, chronic diuretic therapy, conditions predisposing to fluid retention. Renal and hepatic impairment. Underlying coagulation defects or patients who are undergoing surgical procedures where a high degree of haemostasis is required. Pregnancy (avoid in 3rd trimester) and lactation.
