A recent paper studied the effect of most FDA approved drugs on the inhibition of NTCP, the now known entry receptor for HBV.
Ezetimibe was found to have a 50%inhibition conc of 25micromolar, while irbesartan, a commonly used angiotensin inhibitor to reduce blood pressure, was found to inhibit at 11.9 micromolar. Both compounds have similar MW, but irbesartan is given at up to 300mg per day, while exetimibe is dosed at 10mg.
