A cross-sectional retrospective study to assess the pattern of prescribing for inpatient hypertensive cases in a tertiary hospital and to find out the possible avenues for betterment of hypertension management

Objective: The primary objective of this study was to characterize the prescribing pattern of antihypertensive agents in the tertiary care teaching hospital. The secondary objective of this study was to assess the appropriateness of the prescribing pattern of antihypertensive drugs as per the seventh report of the Joint National Committee (JNC-7) guidelines. Materials and Methods: A cross-sectional, retrospective study for the period of 7 months (June 2012 to January 2013) was conducted. Only inpatient hypertensive cases suffering from essential hypertension with or without other comorbid conditions were included in the study. Results: A total of 261 hypertensive patients on treatment, of which 57.9% were females and 42.1% males, were included. Hypertension alone was present in 26.8% of the patient whereas diabetes mellitus was the most common comorbid condition in 18.8% of the cases. Of the 261 patients studied, 47.1% were on monotherapy and 52.8% on combination therapy. The commonest monotherapy agents being prescribed were calcium channel blockers (CCBs) (26.8%), followed by diuretic (9.6%), angiotensin-converting enzyme inhibitor (ACEI) (5%), beta blockers (BBs) (3.8%) and angiotensin receptor blockers (ARBs) (1.9%). The commonest two drug therapy was with CCB and diuretic (15.7%), followed by CCB and BB (7.3%), CCB and ACEI (4.2%), ACEI and diuretic (3.4%), ARBs and diuretic (2.7%), BBs and diuretic (1.9%). The commonest three drug therapy was with CCBs, BBs, and diuretic (4.2%). Conclusion: The most favored class of antihypertensive drugs, either as monotherapy or combination therapy in hypertensive patients with or without comorbidities was CCBs. There was underutilization of thiazide diuretics, ACEIs and BBs in this study. Overall the general pattern of antihypertensive prescribing in this study is only partly in accordance with the guidelines of JNC-7.
