Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective alpha-1 adrenergic receptor antagonist; inhibits vasoconstriction and reduces peripheral vascular resistance via blockade of postsynaptic alpha-1 receptors on vascular smooth muscle.
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.
Initial: 1 mg orally once daily at bedtime, gradually increased to 2-20 mg/day in divided doses.
8 mg orally once daily with a meal.

Clinical Note
moderateSilodosin + Digoxin
"The serum concentration of Digoxin can be increased when it is combined with Silodosin."

"The serum concentration of Levofloxacin can be increased when it is combined with Silodosin."
Clinical Note
moderateSilodosin + Tranilast
"Silodosin may increase the hypotensive activities of Tranilast."

2–3 hours in normotensive patients; prolonged to 6–10 hours in hypertension; extended by renal impairment (up to 4–6 hours in creatinine clearance <10 mL/min)
Terminal half-life: 11-13 hours; allows once-daily dosing; prolongation in severe renal impairment
