A prospective study of adverse drug reactions to artemisinin-based combination therapy in a tertiary care hospital in India

Abstract

Objectives:Antimalarial drugs are commonly prescribed for the treatment of malaria and suspected cases of malaria in India. The recent trend is to prescribe ACT and the incidence of adverse reactions to this therapy is notwell-documented in Indian population. Therefore, this study was designed to assess ADR pattern of antimalarial drugs particularly ACT in India.Materials and Methods:Over a period of 1 year, 500 patients who were administered antimalarial drugs were enrolled in the study. The World Health Organization causality assessment scale was used for classifying the ADR.Results:In this study out of 500 patients, 251 complained of ADRs. The sex-wise difference in reporting of ADRs was statistically not significant (P=0.0943). The most common ADRs reported were nausea, anorexia and vomiting. ADRs were most commonly reported when chloroquine was coprescribed.Conclusions:This study indicates that ACT was commonlyused in the treatment of malaria. Results of the analysis suggest that all the ADRs were of moderate intensity and no serious ADR was observed. This baseline information will be useful to implement the ACT in India.
