Adverse events following remdesivir administration in moderately ill COVID-19 patients - A retrospective analysis

INTRODUCTION: Remdesivir, an antiviral drug, received an emergency use authorization for treating coronavirus disease 2019 (COVID-19) patients. Though many studies have reported the safety aspects of this antiviral agent, most of them were observed in severely ill COVID-19 patients, making very less data available in the moderately ill patients. The present study was conducted with an objective of finding the adverse events (AEs) associated with remdesivir in moderately ill COVID-19 patients. METHODOLOGY: A retrospective observational study was conducted by collecting data of demographic details and details of remdesivir, laboratory investigations, and AEs from the patient medical records from May to July 2021 and analyzed by using the appropriate statistics. RESULTS: Out of the 160 COVID-19 patients, 32 were moderately ill (males: 29, females: 03) and were treated with remdesivir along with steroids and low molecular weight heparin (LMW) heparin. The average number of administered remdesivir doses was 4, with a loading dose of 200 mg and a maintenance dose of 100 mg. A total of 41 AEs were observed out of which 17 were adverse drug reactions (ADRs) (a significant increase in the alanine transaminase (ALT) [P < 0.001]) and 23 AEs (a significant rise in random blood sugars, RBS [one of the AEs] [P = 0.007]). The AEs were more commonly seen in the hypertensive patients. An increased oxygen requirement was a major serious AE observed in four patients. CONCLUSION: Remdesivir caused a significant increase in the liver enzymes. Increased blood sugar levels were the most common AE and increased oxygen requirement was the major serious AE observed.
