Abstract

The effect of diazepam on blood glucose concentration (BGC) was investigated in a double-blind cross-over study in 10 healthy and 10 non-insulin-dependent diabetic subjects taking oral hypoglycemic drugs. In the first session, fasting blood samples were taken for blood glucose and glycosylated hemoglobin estimation and at 60, 80, 95, 125, and 155 minutes thereafter for glucose estimation. In another 2 sessions, a venous sample was taken immediately before premedication (5 mg diazepam or placebo randomly given during breakfast). One hour later a blood sample was taken, and the volunteers were submitted to periodontal treatment after injection of 1.8 mL of 2% mepivacaine with 1:100,000 adrenaline. Venous blood samples were taken at 15, 30, 60, and 90 minutes after injection. The changes in BGC were analyzed using analysis of variance (ANOVA) for repeated measures; the means were compared using Tukey test (P = .05). Statistically significant differences in the BGC were observed between diabetic and nondiabetic groups (P = .00003). However, there were no significant differences among the sessions of the same group (P = .29). The results of this study show that a single dose of 5 mg diazepam before dental treatment does not influence BGC in nondiabetic and non-insulin-dependent diabetic subjects.
