Background: Preliminary data indicates there is a cholinergic basis to insulin secretion. Aims & Objective: To investigate the impact of oral anticholinergics on insulin secretion in subjects with impaired glucose tolerance (IGT), in comparison with volunteers having normal glucose tolerance (NGT). Material & Methods: This prospective observational study recruited 10 IGT and 10 NGT subjects. An oral glucose tolerance test (OGTT) was conducted twice in the absence and presence of hyoscine butyl-bromide (HBB). The plasma glucose (PG) and insulin levels were serially estimated at 30-min increments for 2 h after the OGTT. Early (ΔI30/ΔPG30) & late (insulin/PGAUC 60-120) phase insulin activity were assessed subsequently. Results: The study constituted of 10 IGT (4M/6F, BMI: 28.80 ± 2.30) and 10 NGT (5M/5F, BMI: 23.00 ± 0.80) subjects. In the NGT group, the pre-HBB mean glucose levels (0-120 min) were comparable with those recorded after HBB intake. However, after HBBB, the mean insulin levels decreased significantly at t = 90 and 120min, confirmed by attenuated late phase insulin activity in IGT (P = 0.023) & NGT (P = 0.006) group. On the other hand, in the IGT group, however, HBB did not impact on the mean PG and insulin levels (0-120 min). Conclusions: Our study findings indicate that insulin secretion is influenced by cholinergic system and that oral anticholinergics may attenuate the late phase insulin activity in varying degrees of glycemic status.
