Abstract


Background: Every drug has the potentiality to cause an adverse drug reaction (ADR). ADRs are a major problem in drug therapy .The aim of this study was to assess the incidence and causality of ADRs to antihypertensive agents used for the essential hypertensive patients attending at the general medicine out patients departments of Hi-Tech Medical College and Hospital, Bhubaneswar Odisha, during the time period of November 2016 to October 2018.

Methods: This prospective-observational study was carried out in general medicine outpatient department of Hi-Tech Medical College and Hospital, Bhubaneswar, Odisha.

Results: Out of 254 patients, 78 (30.71%) patients were developed ADRs to antihypertensive drugs. 51 (65.38%) were female and 27 (34.62%) were male. Calcium channel blockers were the commonest therapeutic class of antihypertensive drugs associated with ADRs (n = 50, 64.10%). According to WHO causality assessment scale most of the ADRs were “probable” 41 (52.56%), followed by “possible” 21 (26.92%), unclassifiable 13 (16.67%) and unlikely 3 (3.85%).

Conclusions: The results of this study concluded that antihypertensive drugs able to induce the development of adverse drug reactions, which were significant cause of increase burden on health care system and decrease the quality of life, the health care professionals should take care about the rational use of antihypertensive agents. Thus, to minimize the incidence of adverse drug reaction and to increase the quality of life.
