Background:
Non-adherence to antihypertensive medication is a key factor contributing to uncontrolled blood pressure and the subsequent complications of hypertension. Despite its importance, there is a lack of data regarding the prevalence of and factors associated with non-adherence to medication among individuals with hypertension in India. This review aimed to assess medication adherence rates among hypertensive patients in India and identify the factors influencing non-adherence.
Methods:
A comprehensive search was conducted across PubMed, Scopus, Embase, and Google Scholar. Studies reporting medication adherence/non-adherence to antihypertensive medications in India, using the Morisky Medication Adherence Scale (MMAS), with publication dates up to July 2023, were included.
Results:
Twelve studies were included, involving a total of 3164 participants. The pooled rate of medication adherence to antihypertensive medications in India was determined to be 15.8% (95% CI: 4.4; 43.4). The important factors associated with non-adherence included higher age, medication regimen complexity, low socioeconomic status, low education levels, uncontrolled blood pressure, and comorbidities.
Conclusions:
The adherence rate to antihypertensive medication was observed to be quite low. Therefore, it is imperative to enhance the rate of medication adherence among individuals with hypertension in order to attain effective blood pressure control and reduce the burden of non-communicable diseases.
