Prevalence, Pattern and Monitoring of Adverse Drug Reaction in Tertiary Care Psychiatry Setting- A Hospital Based Study in South Kerala

Abstract

Pharmacovigilance programs usually aim to gather information on the effect of prescribed drugs in the real world rather than in groups of short-lived and carefully selected clinical trial populations. Adverse drug reactions (ADR) associated with psychiatric medications may vary among different populations. As compared with other fields, in Kerala the research related to ADRs and Prescription patterns in psychiatry is scarce. A hospital based cross sectional observational study was undertaken in the Mental Health Centre, Trivandrum.  All psychiatric drugs were closely monitor for adverse drug reaction irrespective of their psychiatric diagnosis. CDSCO Suspected adverse drug reaction reporting form was  used for the documentation of adverse drug reaction and the causality assessment was  done with naranjo scale .The severity of ADR was assessed using Hartwing scale and Preventability assessment using Modified schumock. In this study it was found the highest incident of ADR was reported with risperidone (24%) followed by valproate (20.1%), clozapine (17%) etc. The patient in psychiatry cant identify the adverse effect due to the cognitive impairment. So special attention is necessary for psychiatric patient to find out the incidence of adverse drug reaction and provide the proper management to them.
