Conclusion: HTN is high among old aged (>48yrs) diabetic males with High risk of cardiovascular disease and kidney disease with stage II hypertension, Defined as systolic blood pressure of ≥160mmHg and diastolic blood pressure of ≥100mmHg.Ourstudy revealed that the majority of patients experienced HTN for >two years. Diuretics were prescribed frequently, followed by other anti-hypertensives. Poor understanding of consequences with uncontrolled hypertension, non-adherence to medication and low salt diet , alcohol abstinence, ,increased stress, decreased physical activity, and advanced age were the causes of uncontrolled BP. Early bloodpressure monitoring by a clinical pharmacist can improve patient’s quality of life . To prevent problems, ongoingpatient counselling, health education, and information about patients' adherence and satisfactionin each follow-up are crucial.
