Pharmacovigilance (PV) plays a key role in the management of ADRs. To assess the pharmacist’s knowledge, attitudes and behavior of ADRs among community and hospital pharmacists in Gujarat, a validated questionnaire was developed and used to assess the understanding, attitudes and behavior of community and hospital pharmacists. 166 community pharmacists and 37 hospital pharmacists agreed to complete the ADR questionnaire. According to the study, the response of male pharmacists was higher than that of female pharmacists. In response to knowledge and practice, only the proportion of community pharmacists reporting ADR was 25 %, far lower than hospital pharmacists, who reported 65 %. Factors that encouraged the pharmacist to report ADR were the incredibly potent drug reactions, responses to the new product, and also well-recognized drug reactions documented in this study. In this study, 35 (94 %) hospital and 118 (75 %) community pharmacists guided and advised patients on their side-effects; while 25 (68 %) hospital and 115 (70 %) community pharmacists advised patients on what to do if they developed side-effects. The results of this study suggest that community pharmacists and hospital pharmacists in Gujarat need to improve their knowledge of the ADR. Pharmacists, on the other hand, should be participating in ADR awareness-raising events and refresher courses. a Department of Pharmacology, Ramanbhai Patel College of Pharmacy, Charotar University of Science and Technology, CHARUSAT Campus, Changa – 388 421, Gujarat, India b Department of Pharmaceutical Technology, Ramanbhai Patel College of Pharmacy, Charotar University of Science and Technology, CHARUSAT Campus, Changa – 388 421, Gujarat, India c Department of Pharmaceutical Chemistry, Ramanbhai Patel College of Pharmacy, Charotar University of Science and Technology, CHARUSAT Campus, Changa – 388 421, Gujarat, India *For Correspondence: E-mail: nivyrx@gmail.com https://doi.org/10.53879/id.60.04.12923 Keywords: Adverse Drug Reaction, Knowledge, Attitude, Behaviour, Hospital and Community Pharmacist INTRODUCTION Adverse Drug Reactions (ADRs) are considered to be a significant cause of death in developing and developed countries. ADR may occur after a single dose or prolonged administration of a drug, or may result from a combination of two or more drugs. WHO has defined (ADR) as a response which is noxious and unintended, and which occurs at doses normally used in humans for the prophylaxis, diagnosis, or therapy of disease, or for the modification of physiological function. Pharmacovigilance has defined step with the World Health Organization (WHO) as “A science and activity for the detection, assessment, understanding, and prevention of adverse effects or other possible drug-related problems”. Pharmacovigilance (PV) plays a key role in controlling adverse drug reactions (ADRs), which is why research expansion and growth are safe and effective in clinical regulation and practices 4 . The thalidomide tragedy is a landmark for the roots and development of pharmacovigilance 1 . All facets of the health care system that participate in the reporting process, such as public and private, were included. Hospitals, general practitioners, nurses, specialized clinics, hospitals, and pharmacists were included. Where medicines are used, one should be prepared to detect and report possible adverse reactions or events 2,3 . Awareness and actions of ADR group and hospital pharmacists assess their significance in healthcare
