Drug utilization study of anti-hypertensive drugs and prescription pattern adherence with joint national committee-8 guideline

Karan M. Suthar, Gurusharan H. Dumra


Background: Hypertension is a major and serious non-communicable disease. It is also a major risk factor for cerebrovascular strokes, coronary artery thrombosis, and renal failure. The overall prevalence of hypertension in India is 29.8%. Joint national committee-8 guidelines on prevention, detection, evaluation, and treatment of high blood pressure highlight that aggressive blood pressure control is essential for the reduction of hypertension-associated morbidity and mortality.

Methods: It was a cross-sectional, observational study. Prescriptions were collected from four pharmacy stores located in four different areas of Ahmedabad over a period of 2 months. These were analysed along with relevant co-morbidities and, the level of prescription pattern adherence was assessed as per JNC 8 guidelines. Appropriate statistical tests were applied for analyses of collected data.

Results: A total of 321 prescriptions were collected. Out of them, 186(57.9%) were prescribed to male patients while 135 (42.1%) were for female patients. Mean systolic and diastolic blood pressure was found to be 152 mmHg and 91 mmHg respectively. The mean age of the patients was found to be 44.63 years. A total of 209 (65.1%), 91 (28.34%), 21 (6.54%) prescriptions had monotherapy, dual therapy, and polytherapy for treating hypertension respectively. Amlodipine (CCBs) was found to be the most commonly prescribed medicine as a monotherapy. The overall adherence rate was found to be 77.88%.

Conclusions: The present study demonstrated that medical professionals are not completely adhering to standard guidelines while prescribing antihypertensive drugs. There is substantial scope for improvement, particularly the utilization of antihypertensive agents in patients of the pre-hypertension category, where non-pharmacological measures play an important role to treat the condition.
