Dược Động Học :
▧ Absorption :
Well absorbed from the gastrointestinal tract. Coadministration of food increases the rate of absorption and subsequent appearance of 6MNA (the active metabolite) in the plasma but does not affect the extent of conversion of nabumetone into 6MNA.
▧ Protein binding :
The active metabolite, 6MNA, is more than 99% bound to plasma proteins.
▧ Metabolism :
Undergoes rapid biotransformation to the principal active metabolite, 6-methoxy-2-naphthylacetic acid (6MNA). Approximately 35% of a 1000 mg oral dose of nabumetone is converted to 6MNA and 50% is converted into unidentified metabolites which are subsequently excreted in the urine.
▧ Route of Elimination :
Approximately 35% of a 1000 mg oral dose of nabumetone is converted to 6MNA and 50% is converted into unidentified metabolites which are subsequently excreted in the urine.
▧ Half Life :
Approximately 23 hours for the active metabolite, 6MNA. Increased in patients with renal insufficiency.
▧ Clearance :
* 20 - 30 mL/min
