Decreased biliary excretion of tributylmethyl ammonium in cholestyramine pretreated rats due to reduced formation of ion-pair complexes with hepatic bile salts.

abstract：:In order to determine the absolute bioavailability, both oral and intravenous administrations of a drug are often used. Recently a new method has been proposed to determine absolute bioavailability in the absence of intravenous dose. Following a single oral dose, this method requires oral and renal clearance data from...
