Background Diabetes mellitus and hypertension frequently co-exist in a patient. In such patients, the risk of complications, morbidity and mortality increases. One should be careful in management and choosing drugs. Authors undertook this study to understand the prescribing pattern of the physicians in diabetic hypertensive patients.

Methods This cross sectional, observational study was conducted in type 2 diabetic outdoor patients with co-existing hypertension, for duration of one year. We used descriptive statistics to analyze data of 615 patients to determine prescribing pattern of drugs.

Results 93.17% of patients were more than 40 years of age. Ratio of female to male patients was 1.30. Mean duration of diabetes was 5.81 years. Multi drug anti diabetic regimes (54.47%) were common than monotherapy (43.90%). Commonly prescribed anti diabetic drug groups were biguanides (89.27%), Sulfonylureas (43.90%) and insulin (15.28%). Metformin (89.27%), glibenclamide (29.11%) and insulin (15.28%) were commonly prescribed anti diabetic drugs. Metformin was the most common monotherapy drug and biguanide + sulfonylurea was the most common two drug combination. Commonly prescribed drugs for co-morbid conditions were enalapril (83.41%), aspirin (30.41%), amlodipine (29.76%) atorvastatin (27.32%) and famotidine (26.34%). Average number of drugs prescribed in a prescription was 4.65. Prescriptions with injections were 15.93% and with brand names were 13.15%.

Conclusions Prescribing pattern of drugs was as per current practices and recommendations of guidelines. Still, there is room for improvement in choice of drug, prescribing drug with generic name and choosing drug from essential medicine list.
