Summary
Safinamide may inhibit intestinal BCRP, which can raise the absorption and systemic exposure of BCRP substrates such as fluvastatin. This could increase statin-related adverse effects such as myalgia, although the clinical effect is expected to be modest.
What this interaction means in plain words
Fluvastatin and Safinamide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Fluvastatin belongs to Cardiovascular; Safinamide belongs to Central Nervous System.
Why it happens
Inhibition of intestinal BCRP efflux by safinamide increases fluvastatin bioavailability.
What to do
No routine dose change is needed; ask the patient to report unexplained muscle pain or weakness. Consider checking creatine kinase if symptoms occur.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
