Abstract
Purpose:
We report a case of prolonged nocturnal penile tumescence (NPT) caused by the antiallergic agent epinastine.
Methods/Results:
We measured NPT using Rigiscan-Plus (DacoMed, Minneapolis, MN, USA) with or without the patient having taken epinastine.
Conclusions:
Considering its pharmacological effects on cyclic nucleotides, epinastine may have an effect on erectile function.
