Naftopidil for the treatment of urinary symptoms in patients with benign prostatic hyperplasia
Naftopidil , approved only in Japan , is an α1-adrenergic receptor antagonist ( α1-blocker ) used to treat lower urinary tract symptoms ( LUTS ) suggestive of benign prostatic hyperplasia ( BPH ) . Different from tamsulosin hydrochloride and silodosin , in that it has higher and extremely higher affinity respectively , for the α1A-adrenergic receptor subtype than for the α1D type , naftopidil has distinct characteristics because it has a three times greater affinity for the α1D-adrenergic receptor subtype than for the α1A subtype . Although well- design ed large-scale r and omized controlled studies are lacking and the optimal dosage of naftopidil is not always completely determined , previous reports from Japan have shown that naftopidil has superior efficacy to a placebo and comparable efficacy to other α1-blockers such as tamsulosin . On the other h and , the incidences of ejaculatory disorders and intraoperative floppy iris syndrome induced by naftopidil may be lower than for tamsulosin and silodosin having high affinity for the α1A-adrenergic receptor subtype . However , it remains unknown if the efficacy and safety of naftopidil in Japanese is applicable to white , black and Hispanic men having LUTS/BPH in western countries
