Alpha1D-adrenoceptors (α1D-ARs) located in the spinal cord are involved in the control of lower urinary tract function. In order to clarify the effect of α1D-ARs on storage function in the spinal cord, we examined the effect of oral administration and

Two bioanalytical HPLC methods (chiral solid phases (CSPs) HPLC and pre-column derivatization HPLC) were developed and validated for the determination of naftopidil enantiomers in rat plasma. Analytes were extracted from biomaterials by liquid-liquid extraction. The pre-column derivatization HPLC method employed

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

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
