Anti Hypertensive Prescribing Patterns and Cost Analysis for Primary Hypertension: A Retrospective Study

Objective: The present study was conducted to analyze the current prescription pattern and cost analysis of antihypertensive drugs in hypertensive patients in a tertiary care hospital. Materials and Methods: A retrospective cross-sectional study was conducted in tertiary care hospital, Bangalore for three months and utilized 300 prescriptions for the analysis. The data analysed from the prescription included patients demographics, stage of hypertension according to JNC VII guidelines, type of drug therapy, class of anti-hypertensive, and cost effectiveness of therapy. Drug acquisition costs was calculated, using the cost of the cheapest available drug and the most commonly prescribed dosage, for each drug on a daily and annual basis. Total annual drug expenditure on buying required doses of all antihypertensive prescribed in the study population for a year was calculated. Results: Monotherapy (48.94%) was leading trends of antihypertensive therapy followed by fixed dose combination (35.04%) and polytherapy (16.01%). The most frequent antihypertensive class to be prescribed were CCBs (38.59%) followed by beta blockers (24.07%). The ranking in terms of cost utilized per year from the highest to the lowest found in this study was: alpha blockers> ACE-inhibitors> ARBs> CCBs> beta blockers > diuretics. The diuretics were most cost-effective (Cost per day: 5.89 ± 2.87; Cost per year: 2129.02 ± 1080.49) in relation to the other antihypertensive prescribed.
