This study was designed to compare the effects of equivalent therapeutic doses of two H2 antagonists, cimetidine and ranitidine, on tolbutamide pharmacokinetics. Twelve healthy men were given a 1-g oral dose of tolbutamide on three occasions. Subjects were randomly assigned

The hypoglycemic sulfonylureas glyburide and tolbutamide were found to be excellent inhibitors of the rat liver, heart, and skeletal muscle carnitine palmitoyltransferases, but glyburide was by far the most potent inhibitor. Carboxytolbutamide, a sulfonylurea that has no hypoglycemic effect, produced

The in vivo effects of oral clarithromycin administration on the in vivo activity of cytochrome P450 1A2, 2C9, and 2D6 were determined. The cytochrome P450 probes caffeine (CYP1A2), tolbutamide (CYP2C9), and dextromethorphan (CYP2D6) were administered as an oral cocktail prior

A high-performance liquid chromatographic method was developed for the simultaneous measurement of tolbutamide and its major metabolite, carboxytolbutamide, in plasma. The assay involves the ether extraction of 1 ml of plasma, using chlorpropamide and an internal standard. The extract is

The mechanisms by which glyburide and tolbutamide signal insulin secretion were examined using a beta cell line (Hamster insulin-secreting tumor (HIT) cells). Insulin secretion was measured in static incubations, free cytosolic Ca2+ concentration ([Ca2+]i) was monitored in quin 2-loaded cells
