Many pharmacological agents and their metabolites are cleared and excreted into bile fluid. Using bile duct cannulation, the amount and rate of biliary drug excretion can be determined. Biliary secretion studies assist in determining the clearance route of a novel compound of interest.
Pharmacokinetic (PK) Study
Rats (Bile duct cannulated)
Bile duct cannulated rats can be dosed either p.o., i.v., s.c. or i.p. with a compound of interest. Bile fluid will be collected at set time points, but will not be allowed to drip for longer than 8-hours.
