ABSTRACT
Present investigation was undertaken to study the effects of 6 week treatment with spirapril (2 mg/kg po) on insulin sensitivity, and serum lipid levels in streptozotocin (STZ)-diabetic and spontaneously hypertensive (SH) rats. Treatment of rats with spirapril in diabetic and diabetic with hypertensive animals significantly prevented STZ-induced loss of body weight, hypertension, and bradycardia. It also partially but significantly prevented STZ-induced hyperglycaemia in both diabetic Wistar and SH animals. Insulin level was not altered by spirapril treatment. There was significant reduction in cholesterol levels in the diabetic rats. In conclusion, the present investigation presents a number of beneficial effects of spirapril treatment in diabetic and/or hypertensive rats. Spirapril may be considered as one of the drugs of choice in treatment of hypertension when associated with diabetes
