Darolutamide and Atorvastatin Combination Safety

Key Considerations for Safe Co-administration

• The American Heart Association recommends that atorvastatin doses >10 mg daily are not recommended when combined with agents that inhibit OATP1B1 and other transporters without close monitoring 1
• Atorvastatin should be limited to a maximum of 10 mg daily when co-administered with darolutamide, extrapolating from established guidelines for similar transporter-mediated interactions 1

Essential Monitoring and Management

• Obtain baseline creatine phosphokinase (CPK) levels before initiating combination therapy 1
• Check CPK levels if any muscle symptoms develop 1
• Advanced age increases the risk of muscle toxicity with this combination 2
• The American Heart Association suggests monitoring for muscle symptoms and assessing CPK levels at baseline and regularly during treatment, with a maximum atorvastatin dose of 10 mg daily 1

Alternative Statin Options

• Pravastatin, fluvastatin, and pitavastatin have less reliance on BCRP and OATP transporters compared to atorvastatin, but require the same cautious approach with low doses and close monitoring 1
