Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective antagonist of postsynaptic alpha-1 adrenergic receptors in the prostate, bladder base, and prostatic urethra, leading to smooth muscle relaxation and improved urine flow.
Silodosin is a highly selective antagonist of alpha-1A adrenergic receptors located primarily in the prostate, bladder base, and proximal urethra. Blockade of these receptors relaxes smooth muscle in these tissues, reducing urinary outflow resistance and improving symptoms of benign prostatic hyperplasia (BPH). It has minimal affinity for alpha-1B receptors, thereby reducing the risk of orthostatic hypotension compared to non-selective alpha blockers.
10 mg orally once daily immediately after the same meal each day. Extended-release tablet.
