Abstract
Background: Adverse drug reactions (ADRs) are an important concern in modern therapeutics. Due to limitations in identifying ADRs during research phase, organized post marketing studies are essential. However, there are only few recent studies on this subject available in India. Hence this study was done in a tertiary care hospital in South Kerala to evaluate the profile and causality of ADRs.Methods: The details of patients who developed ADRs during the period from October 2016 to November 2017 were collected. Data collection was done using the suspected drug reactions monitoring form by CDSCO used under PvPI and a retrospective observational cross-sectional analysis was done. The profile and causality of ADRs were evaluated.Results: The total number of ADR events reported was 300. 179 ADRs were hypersensitivity reactions (Aronson Type B) and the remaining 121 reactions were Type A reactions. The individual drug class causing majority of the ADRs was antibiotics (36%). Commonest significant dose related ADR was bleeding (7%) caused by combined use of antiplatelets and anticoagulants. The organ system most affected as per SOC classification was skin and appendages (56%). Causality assessment revealed that majority (76%) belonged to “probable” category, whereas 23.6% were of “possible” type.Conclusions: The development of ADRs can significantly affect treatment course – interruption of drug therapy, use of additional drugs and prolonged hospital stay. Employing monitors dedicated to ADR detection and education of prescribers to closely monitor patients can help manage ADRs effectively.
