Dược Động Học :
▧ Absorption :
For sustained release, peak plasma concentrations are achieved within 3 hours.
▧ Protein binding :
84 %
▧ Metabolism :
Reduction of the carbonyl groupand/or hydroxylation of the tert-butyl group of bupropion.
▧ Route of Elimination :
Bupropion is extensively metabolized in humans. Oxidation of the bupropion side chain results in the formation of a glycine conjugate of metachlorobenzoic acid, which is then excreted as the major urinary metabolite. Following oral administration of 200 mg of 14C-bupropion in humans, 87% and 10% of the radioactive dose were recovered in the urine and feces, respectively. However, the fraction of the oral dose of bupropion excreted unchanged was only 0.5%, a finding consistent with the extensive metabolism of bupropion.
▧ Half Life :
24 hours
