Abstract
Objective: To evaluate the temporal trends in the prescription patterns of antihypertensive medications among healthcare practitioners in India. Design and method: The IQVIA (formerly Quintiles and IMS Health) prescription audit data came from prescriptions of a panel of 6000 private sector primary care clinicians for the different classes of antihypertensive drugs; beta-blockers (BB), calcium channel blockers (CCB), angiotensin receptor blockers (ARB), angiotensin-converting enzyme (ACE) inhibitors, and diuretics were examined. The analysis encompassed the period from 2014 to 2022. Additionally, combinations of these drug classes involving two or three medications were also subject to analysis. Results: Cardiologists’ prescription rates for antihypertensive medications stood at 21% in 2017 and decreased to 19% by 2023. In 2023, the highest rate of prescribing antihypertensive drugs was observed among consultant physicians, with a rate of 30%, followed by general practitioners at 27%. In addition, during COVID-19, the prescription share of general practitioners was highest (31%). Among anti-hypertensive medications, the prescription rates for BBs were highest (32%), followed by ARBs & CCBs (25% & 24% respectively). Single-drug formulation of antihypertensive medications was the most preferred (60%) among Indian clinicians. Prescription shares of fixed-dose combinations (FDC) of two antihypertensive drugs showed a slight decline (36% in 2017 to 34% in 2023) & FDCs of triple-drug exhibited an upward trend (3% in 2017 to 5% in 2023). Among the two drug FDCs, ARB & diuretics were most preferred (25% prescription share) & triple drug FDCs, CCB, ARB & diuretics were most preferred. Conclusions: Cardiovascular medications hold a prominent position in the Indian pharmaceutical market, with antihypertensives standing out as one of the most frequently prescribed treatments. Consultant physicians and general practitioners manage the majority of hypertension cases. Notably, there has been an observed rise in the preference for triple-drug combinations of antihypertensive medications, indicating a trend toward a more aggressive approach to hypertension management among Indian clinicians. The insights gleaned from this investigation can further assist healthcare professionals in crafting tailored treatment strategies for individuals grappling with hypertension. Such personalized approaches hold promise in enhancing treatment adherence and ultimately improving the QoL.
