title: Calcium antagonists and hormone release. VIII. Effects of verapamil infusion on C-peptide to insulin molar ratio in normal subjects and obese subjects with normal glucose tolerance.
abstract: It is known that calcium-antagonist drugs can modify the insulin response to various secretagogues. In order to clarify whether calcium-antagonist effect was directed at the level of pancreatic insulin secretion or hepatic insulin extraction and further investigate the pathogenesis of hyperinsulinemia in obesity, an oral glucose tolerance test (OGTT) was performed in basal conditions and during a Verapamil infusion (VE, 5 mg/h x 3.5 h) in 12 normal subjects and 14 obese patients with normal glucose tolerance.(ABSTRACT TRUNCATED AT 250 WORDS)
