Comparison of Losartan and Amlodipine in hypertensive type-II diabetic patients

The present study assesses whether Losartan and Amlodipine, alone or in combination, prevent microalbuminuria in hypertensive type II diabetic patients. Department of pharmacology, Basic Medical Sciences Institute [BMSI], Jinnah Post Graduate Medical Centre, Karachi from June 2006 to January 2007. In this study 60 hypertensive diabetic patients were divided into 3 groups having 20 each. Group 'N' patients were kept as control, group 'A' patients were treated with Losartan, 50 mg once daily, group 'B' with Amlodipine 10 mg once daily and Group 'C' patients were given a combination of both the drugs i.e. tab losartan and tab amlodipine. Tablet Glibenclamide 5 mg was given according to the glicemic control. Although all the three groups showed a comparable effect in lowering both the systolic and diastolic blood pressure but the effect on proteinuria was variable. Losartan treated patients in Group 'A' shows marked reduction of proteinuria but non-significant change in creatinine clearance. In Group 'B' the patients who were treated with Amlodipine showed significant reduction in creatinine clearance, but non-significant change in proteinuria and Group 'C' patients showed countable reduction in proteinuria but a non-significant increase was observed in creatinine clearance. The results suggest that in hypertensive type II diabetic patients Losartan is worthwhile reducing both systolic and diastolic blood pressure and proteinuria significantly
