Metabolism of 6,7-dimethoxy 4-(p-chlorobenzyl)-isoquinoline. I. Single-dose pharmacokinetics in the rat and mouse.
The pharmacokinetics of 6,7-dimethoxy 4-(p-chlorobenzyl) isoquinoline (PV 2) in mouse and rat show that it is 52% absorbed after oral administration and undergoes a marked hepatic first-pass effect (83%). Tissue distribution shows an affinity for the aorta, cardiac tissues and cerebral blood vessels. It is excreted in the urine (20% dose) and faeces (70%); biliary excretion is high (80% dose). It is metabolized mainly by O-demethylation to 6- and 7-desmethyl-PV 2 and 6,7-didesmethyl-PV 2, as well as to six other non-identified metabolites.
