Efficacy and safety of single versus multiple daily doses of glibenclamide in type 2 diabetes mellitus.
Although long acting, glibenclamide is frequently given in split doses for type 2 diabetes mellitus. This may discourage compliance. It is thus appropriate to consider dosing it less frequently. We therefore studied glibenclamide effects when used once daily and when used in split doses. Our objective was to assess the feasibility of using once daily dosing as a regimen of choice. We measured plasma glucose, insulin, glibenclamide, lipids, HbAl and body mass index associated with the regimens. We also compared the number of hypoglycemic episodes occurring with them. Thirty type 2 diabetics on multiple daily glibenclamide were enrolled. Their regimens were changed over to once daily. Blood for glucose, insulin, lipids, HbAl and glibenclamide and body weight measurements were determined before and after the crossover period. We found no major difference in the sugar and insulin profiles with the two regimens. Fasting total cholesterol and triglyceride were also similar and so were plasma glibenclamide. The HbAl levels and body mass index and number of minor and major hypoglycemic episodes and hospital admissions for hypoglycemia also did not differ. We conclude that single daily dosing of glibenclamide was equivalent to multiple daily dose regimens. It can be used to an advantage to improve patient's compliance.
