To compare the efficacy of three α(1A)/α(1D)-adrenoceptor (AR) antagonists--naftopidil, tamsulosin, and silodosin--that have differing affinities for the α(1)-AR subtypes in treating urinary morbidities in Japanese men with (125)I prostate implantation (PI) for prostate cancer. This single-institution prospective randomized controlled trial

Journal of cardiovascular pharmacology, 20(6), 1006-1013 (1992-12-01)
The interaction of naftopidil with adrenoceptors was studied in comparison to standard drugs. Naftopidil binds specifically to alpha 1-adrenoceptors. The Ki values are 58.3 nM for naftopidil, 0.43 nM for prazosin, and 197 nM for urapidil. The affinities of naftopidil

Binding properties of naftopidil and alpha 1-adrenoceptor antagonists to alpha-adrenoceptors in prostates from benign prostatic hypertrophy (BPH) were characterized by radioreceptor assays using [3H]prazosin and [3H]rauwolscine. Specific binding of [3H]prazosin and [3H]rauwolscine in human prostatic membranes was saturable and of

The aim of the present study was to compare the efficacy of the selective α(1D) -adrenoceptor antagonist naftopidil and the selective α(1A) -adrenoceptor antagonist silodosin (as an example) in the management of ureteral stones in Japanese male patients. A total

We compared the efficacy, safety, and patient preferences for two α1-adrenoceptor (AR) antagonists with different affinity for AR subtypes, naftopidil (Naf) and silodosin (Silo), for the treatment of male lower urinary tract symptoms associated with benign prostatic hyperplasia (male LUTS/BPH).
