Notes: Silodosin-d4 is intended for use as an internal standard for the quantification of silodosin (Item No. 14866) by GC- or LC-MS. Silodosin is an α1A-adrenergic receptor (α1A-AR) antagonist (Ki = 0.036 nM).{25007} It is 583- and 56-fold selective for α1A- over α1B- and α1D-ARs, respectively. Silodosin inhibits phenylephrine-induced contraction of isolated rabbit prostate (pA2 = 10.05) more potently than rabbit or rat aorta (pA2s = 9.36 and 8.13, respectively).{55032} It inhibits norepinephrine-induced contraction of isolated human prostate tissue when used at concentrations ranging from 0.3 to 10 nM.{25007} Silodosin (0.01-1,000 µg/kg) inhibits phenylephrine-induced increases in intraurethral pressure in rats.{25005} Formulations containing silodosin have been used in the treatment of benign prostatic hyperplasia.
