Description
Overview of the medicine
Chear 50 mg tablet is a non-steroidal anti-inflammatory drug (NSAID) primarily used for symptomatic relief in the treatment of osteoarthritis, rheumatoid arthritis, and for the management of acute pain. It works by reducing inflammation and pain.
Uses & Indications
Dosage
Adults
For osteoarthritis and rheumatoid arthritis: 50 mg once daily. For acute pain: 50 mg as a single dose, or 50 mg twice daily if needed.
Elderly
Usually no dosage adjustment is required, but caution is advised due to increased risk of adverse effects.
Renal_impairment
Initial dose reduction to 50 mg every other day may be considered for severe impairment (CrCl < 30 mL/min). Not recommended for severe renal disease.
How to Take
Administer orally, with or without food. Taking it with food may reduce gastrointestinal discomfort.
Mechanism of Action
Chear selectively inhibits cyclooxygenase-2 (COX-2) enzyme, which is responsible for the synthesis of prostaglandins, mediators of pain and inflammation. By inhibiting COX-2, it reduces the production of these inflammatory prostaglandins, thereby providing anti-inflammatory, analgesic, and antipyretic effects.
Pharmacokinetics
Onset
Within 1 hour for pain relief, but full anti-inflammatory effects may take several days.
Excretion
Excreted predominantly in the urine (about 27%) and feces (about 57%) as metabolites; less than 1% as unchanged drug.
Half life
Approximately 8-12 hours.
Absorption
Well absorbed from the gastrointestinal tract. Peak plasma concentrations are reached in approximately 2-4 hours after oral administration.
Metabolism
Primarily hepatic via cytochrome P450 (CYP2C9) to inactive metabolites.
