Summary

Trofinetide may inhibit OATP1B1/1B3 and raise exposure to substrates of these transporters. Telmisartan uptake is partly OATP-mediated, so exposure may increase modestly, with possible hypotension or renal effects.

What this interaction means in plain words

Telmisartan and Trofinetide can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Telmisartan belongs to Cardiovascular; Trofinetide belongs to Central Nervous System.

Evidence level: Low

Why it happens

Possible inhibition of hepatic OATP1B1/1B3 uptake by trofinetide, raising telmisartan levels.

What to do

Monitor blood pressure and renal function when combining them. Reduce the telmisartan dose if hypotension develops.

What to ask your pharmacist

  • Should I take them at different times of day?
