Dược Động Học :
▧ Absorption :
Absolute bioavailability averages 4%
▧ Volume of Distribution :
* 700 L
▧ Protein binding :
98%
▧ Metabolism :
Hepatic
▧ Route of Elimination :
In vitro studies using human liver microsomes have shown that the metabolism of saquinavir is cytochrome P450 mediated with the specific isoenzyme, CYP3A4, responsible for more than 90% of the hepatic metabolism. Only 1% of saquinavir is excreted in the urine, so the impact of renal impairment on saquinavir elimination should be minimal.
▧ Clearance :
* 1.14 L/h/kg [Healthy volunteers receiving IV doses of 6, 36, and 72 mg]
