Keprofen Tablet (Enteric Coated) 50 mg is a nonsteroidal anti-inflammatory agent (NSAIA) with analgesic and antipyretic properties. Keprofen Tablet (Enteric Coated) 50 mg has pharmacologic actions similar to those of other prototypical NSAIDs, which inhibit prostaglandin synthesis. Keprofen Tablet (Enteric Coated) 50 mg is used to treat rheumatoid arthritis, osteoarthritis, dysmenorrhea, and alleviate moderate pain.

The anti-inflammatory effects of ketoprofen are believed to be due to inhibition cylooxygenase-2 (COX-2), an enzyme involved in prostaglandin synthesis via the arachidonic acid pathway. This results in decreased levels of prostaglandins that mediate pain, fever and inflammation. Keprofen Tablet (Enteric Coated) 50 mg is a non-specific cyclooxygenase inhibitor and inhibition of COX-1 is thought to confer some of its side effects, such as GI upset and ulceration. Keprofen Tablet (Enteric Coated) 50 mg is thought to have anti-bradykinin activity, as well as lysosomal membrane-stabilizing action. Antipyretic effects may be due to action on the hypothalamus, resulting in an increased peripheral blood flow, vasodilation, and subsequent heat dissipation.

Keprofen Tablet (Enteric Coated) 50 mg is rapidly and well-absorbed orally, with peak plasma levels occurring within 0.5 to 2 hours.

99% bound, primarily to albumin

In a 24 hour period, approximately 80% of an administered dose of ketoprofen is excreted in the urine, primarily as the glucuronide metabolite.

Conventional capsules: 1.1-4 hours

Extended release capsules: 5.4 hours due to delayed absorption (intrinsic clearance is same as conventional capsules)
