ABSTRACT
Background: Cutaneous Adverse Drug Reaction (CADR) is considered as one of the reasons for discontinuation of drug as well as medication non-adherence. This study analyses the common drugs causing CADR, clinical spectrum of different types of CADR, causality and drugs causing severe CADR.Methods: This was a retrospective cross-sectional observational study conducted by the Department of Pharmacology, Coimbatore Medical College, Coimbatore, Tamil Nadu, India. The study was conducted using data collected in CDSCO’s ADR reporting forms with CADR from June 2015 to July 2017. Patient’s information, details related to adverse drug reaction, suspected medication details, concomitant medication history, causality and seriousness were recorded.Results: A total of 102 CADR were evaluated in this study. The mean age of sample was 37.21±20.33 years. Maximum number of cases was in the age group of 40-49 years. Male to female ratio was 0.96:1. The commonly incriminated drugs causing CADR were antimicrobial agents. Ciprofloxacin (21.57%), phenytoin (9.8%), diclofenac sodium (6.86%), anti-snake venom (6.86%) and vancomycin (3.92%) were the common drugs implicated in CADR. Maculopapular rash and itching were the most common CADR. Anticonvulsants especially phenytoin was commonly associated with severe CADR.Conclusions: The present study has made an impact on all departments of this institution and awareness has been created about spontaneous reporting of all adverse drug reactions in CDSCO ADR reporting forms to the pharmacovigilance centres. Thus, sound knowledge about the adverse drug reactions may decrease the occurrence of drug induced morbidity and mortality.
