Abstract


Background: Adverse drug reactions (ADRs) have a major impact on public health. Pharmacovigilance has become an integral part of pharmacotherapy. This study has been undertaken to retrospectively analyze the various adverse drug reactions and to promote the reporting of ADRs among the healthcare providers.

Methods: A retrospective analysis of the reported ADRs over a period of 3 years at a tertiary care hospital, in Chennai was done. Data related to the number of adverse drug reactions, the demographic particulars, details on the drugs administered, type of ADRs, serious events and prevention strategies undertaken was analyzed. ADRs were assessed for their causality, severity, and preventability as per the standard criteria.

Results: A total of 128 suspected ADRs were found to be reported over a period of 3 years. 81.25% ADRs were found to be of mild severity using the Hartwigs scale of assessment, 71.09% were classified as possible using the Naranjo’s causality assessment, the outcome of 63.28% were found to be recovering from the ADR and 41.40 % were under the probably preventable category. The most common ADRs were the skin reactions. The antimicrobial agents were found to have caused the highest number (58.59%) of ADRs followed by NSAIDs (14.84%) and the antihypertensive drugs (14.06%).

Conclusions: The antimicrobial agents were associated with ADRs in majority of the patients. The commonly reported ADR s were the skin reactions.
