Description

Naftopidil (INN, marketed under the brand name Flivas) is a drug used in benign prostatic hypertrophy which acts as a selective alpha1-adrenergic receptor antagonist, has been used for the treatment of benign prostatic obstruction and benign prostatic hyperplasia (BPH) associated lower urinary tract symptoms (LUTS). The Japanese Ministry of Health, Labor and Welfare approved naftopidil for treating men with BPH in 1996. Although well-designed, randomized studies are warranted to confirm the long-term outcomes and effector/target of naftopidil, the α1A-antagonist naftopidil, which also blocks α1D-adrenoceptor, improves voiding symptoms, and may also be useful for the management of men with storage symptoms represented by nocturia, retrieving their quality of life impaired by BPH-associated LUTS. The selective alpha1D-blocker naftopidil can significantly facilitate spontaneous passage of distal ureteral stones with few side effects, providing a new choice for medical expulsive therapy.
