Abstract

There is a paucity of data regarding efficacy and safety of concomitant therapy of daptomycin and statins, so we reviewed patients that concomitantly received daptomycin and statins to identify any potential increase in toxicity in our cohort. This retrospective study included all patients that received >6 mg/kg/day of daptomycin along with statins and had efficacy and safety data. Patients on high dose (>6 mg/kg/day) daptomycin therapy that did not received statins served as controls. One hundred four patients were included. Median daptomycin dose was 7.8 mg/kg/day (range 6.5–10.8 mg/kg/day), for a mean duration of therapy of 17 days (range 10–51 days). Thirty-six patients received daptomycin and statins and 68 received only daptomycin. Muscular toxicity defined as CPK levels > 1000 UI/L (2.5 times upper normal limit, range of determination 200–400 UI/L) was equally distributed between both groups (3/36, 8% vs 7/68, 10%; p = 0.746). Despite biochemical toxicity, we did not find clinical toxicity and daptomycin treatment was completed in all cases. We did not find predictors of increased CPK during daptomycin therapy. Based on our data, concomitant administration of daptomycin and statins is safe and is not associated with an increased risk of rhabdomyolysis.
