Webintrinsic clearance (CLint,micr) is determined. CLint,micr (µL min –1 mg–1) is then scaled to in vivo intrinsic (hepatic) clearance (CLint) (mL min–1 kg–1) using suitable scaling factors [including microsomal protein content per gram of liver (MPPGL) and liver mass] obtained from the literature (Table I) (2, 19, 20, 22, 23).
