Abstract

Purpose: This study aims to investigate the potential causal relationship between the use of indapamide and rhabdomyolysis. Previous research and pharmacovigilance monitoring activities have suggested a potential association between indapamide use and rhabdomyolysis. However, limited information is available on this association. Methods: A case-control study conducted using EHR data, between July 1,2016, and December 31,2022. Patients who have rhabdomyolysis event (cases) were matched to four controls bases on age, gender and date. We examined the odds for indapamide exposure through three risk periods: current use, recent use, and former. The study outcome was ascertained through the presence of CK level over 1,000 U/L (i.e. rhabdomyolysis event). Subsequently, a multivariable conditional logistic regression analysis was utilized to assess the causal impact of indapamide exposure on the likelihood of developing rhabdomyolysis, while accounting for potential confounding variables. Results: The study population consisted of 2,965 cases and 11,860 controls. The results of the conditional logistic regression analysis indicated a lack of association between exposure to indapamide for the current users the OR was 0.7 (95% CI: 0.49 - 0.92) and the AOR was 0.6 (95% CI: 0.39 - 1.05). The recent users showed OR of 0.9 (95% CI: 0.56 - 1.50) and AOR of 0.2 (95% CI: 0.14 - 0.47). Lastly, the former users demonstrated an OR of 0.8 (95% CI: 0.47 - 1.26), and AOR of 0.1 (95% CI: 0.07 - 0.23). Conclusions: In this study, we did not find association between indapamide use and rhabdomyolysis regardless timing of exposure.
