Amelioration of erectile dysfunction following a switch from carbamazepine to oxcarbazepine: recent clinical experience.
Oxcarbazepine is an antiepileptic drug (AED) indicated for use as monotherapy and add-on therapy in adults and children 4 years of age and older. Despite being structurally related to carbamazepine, oxcarbazepine differs substantially in its pharmacokinetic and safety profile; oxcarbazepine has a much lower risk of pharmacokinetic drug-drug interactions than carbamazepine. Carbamazepine has also been shown to induce the hepatic synthesis of sex hormone-binding globulin, thus reducing free serum testosterone levels and possibly causing erectile dysfunction (ED) in some men; these effects have not been observed with oxcarbazepine. This paper provides a discussion of recent clinical experience with men who presented in private clinical practice with complaints of ED while being treated with carbamazepine for seizure disorders. The four illustrative case studies presented in this report suggest that switching AED treatment from carbamazepine to oxcarbazepine in men with epilepsy can reduce the ED side effects observed with carbamazepine.
