Evaluation of the efficacy and safety of bromocriptine QR in type 2 diabetes

Abstract

Context: Diabetes mellitus is a chronic metabolic disorder of endocrinal origin with multiorgan involement. Today′s physician has a lot many options to choose for treating type 2 diabetes, but does not always manages to achieve optimal glycemic control. The newer drug bromocriptine acts by novel hypothalamic circadian rhythm resetting mechanism. Objective: To evaluate the efficacy and safety of bromocriptine QR in type 2 diabetes. Materials and Methods: 105 patients according to inclusion and exclusion criteria were randomized into three groups by simple randomization. Group 1 received bromocriprine 2.4 mg once daily, group 2 received metformin 500 mg twice daily while group 3 received bromocriprine 1.6 mg daily and metformin 500 mg twice daily. Baseline measurement of fasting and postprandial blood sugar, HbA1 C and BMI were followed up at 6 th and 12 th weeks. Safety evaluation was done by questioning the patient and also through routine hematological and biochemical parameters. Z test was used for analysis. Results: Group 1 showed significant reduction in fasting and postprandial sugar and HbA 1c at 12 weeks. While groups 2 and 3 showed even higher reduction in these parameters albeit with slightly more adverse drug events like nausea, vomiting compared to group 1. Conclusion: Bromocriptine QR is an effective and safe antidiabetic drug which can be employed as monotherapy or in conjuction with metformin to achieve and maintain optimal glycemic control.
