Pattern and incidence of adverse drug reactions observed in cardiac clinic of tertiary hospital, Hakeem Abdul Hameed Centenary Hospital, Jamia Hamdard, New Delhi

Background The aim of the present study was to monitor the incidence and pattern of adverse drug reactions (ADRs) in cardiac care unit at Hakeem Abdul Hameed (HAH) Centenary Hospital.

Methods Study was conducted with the permission of Institutional Ethics Committee. Patients visiting medicine outpatient department, cardiac clinic, medical ward, and emergency departments over a period of 15 months were recruited. ADRs were recorded on the prescribed form. Causality assessment was done using Naranjo probability scale. 223 patients of hypertension and stable coronary artery disease were enrolled of which 48.9% were males and 51.1% females. The most common prescribed drugs were ace-inhibitors, angiotensin receptor blocker, and beta-blockers. Other prescribed drugs were calcium channel blockers, statins, nitrates, and antiplatelets.

Results A total of 44 ADRs were recorded. 26 ADRs were seen in females and 18 in males. Statins were the commonest drug associated with ADRs (29.5%) in our study. The most common organ system associated with ADRs in the present study was central nervous system followed by skin 15.9% each. The incidence of ADRs was about 20% of which 20% ADRs were probable, and 80% were possible. Maximum ADRs occurred in patients prescribed statins followed by beta-blockers and angiotensin receptor blockers.

Conclusion There is a need for conducting such studies in more and more patients to see the pattern of ADRs in cardiac patients. More information will help in reducing the ADR occurrence and making drug use more rational and safe for patients.
