Abstract
|
|
|
|
The Ha-antagonist, cimetidine, has been shown to retard the hepatic elimination of low and high clearance drugs, and this has been attributed to inhibition of microsomal cytochrome P-450. This study was done to determine the effects of low (50) and high (1mg) dose of famotidine, another histamine H-receptor antagonist, on hepatic elimination of propranolol compared with cimetidine in the isolated perfused rat liver. Both low and high dose of cimetidine not only inhibited the elimination of propranolol but also increased the area under the perfusate propranolol concentration time curve (AUC). In contrast, low and high dose of famotidine did not affect hepatic elimination of propranolol. Our findings suggest that famotidine has not a propensity for hepatic microsomal inhibition.
