Voclosporin + Simvastatin Interaction

Description

In one clinical study the concomitant administration of a single 40 mg dose of simvastatin with 23.7 mg BID voclosporin increased C max and AUC of the active metabolite simvastatin acid (an OATP1B1 substrate) by 3.1-fold and 1.8-fold, respectively [see Clinical Pharmacology ( 12.3 )] . Monitor for adverse reactions such as myopathy and rhabdomyolysis when OATP1B1/OATP1B3 substrates (e.g., simvastatin, atorvastatin, pravastatin, rosuvastatin, pitavastatin, fluvastatin) are used concomitantly with LUPKYNIS and reduce the dosage of these substrates as recommended in their prescribing information. For example, when taking LUPKYNIS with simvastatin, limit the simvastatin dosage to 20 mg daily, or 40 mg daily for patients who have previously tolerated simvastatin 80 mg daily for at least one year without evidence of muscle toxicity.
