๐ฟ What is Indomethacin SR 75 mg (Indocap SR)?
Indocap SR delivers Indomethacin in a sustained-release formulation, providing consistent therapeutic levels over 12โ24 hours. Indomethacin is a potent nonsteroidal anti-inflammatory drug (NSAID) that non-selectively inhibits COX-1 and COX-2 enzymes, reducing prostaglandin synthesis and thus alleviating pain and inflammation in conditions like osteoarthritis, rheumatoid arthritis, gout, and ankylosing spondylitis.
Clinical studies show that SR formulations improve gastrointestinal tolerability and allow once-daily dosing, enhancing adherence and reducing peak-related adverse effects. Patients report significant reduction in joint pain and flare frequency within the first week of therapy.
For detailed prescribing information and safety warnings, refer to the FDA label for Indocin SR and the Drugs.com monograph. Additional guidance is available from the NHS Medicines AโZ and the WHO Essential Medicines List.
