Dutasteride

Tamsulosin Hydrochloride (0.4mg modified-release) and Dutasteride (0.5mg) Tablets/Capsules is a synergistic dual-action therapy on the WHO Model List framework for symptomatic Benign Prostatic Hyperplasia (BPH). Tamsulosin is a uroselective alpha-1A/1D adrenergic receptor antagonist that relaxes smooth muscle in the prostate stroma, prostatic capsule, and bladder neck, rapidly improving urinary peak flow rates and relieving lower urinary tract symptoms (LUTS). Dutasteride is a potent dual type 1 and type 2 5-alpha reductase inhibitor (5-ARI) that suppresses dihydrotestosterone (DHT) synthesis by >90%, progressively shrinking enlarged prostate volume over 3-6 months. Indicated for moderate-to-severe BPH with enlarged prostate (volume >30cc) to reduce the risk of acute urinary retention (AUR) and the need for BPH-related surgery (TURP).

Alfuzosin (10mg prolonged-release) and Dutasteride (0.5mg) Tablets is a fixed-dose combination combining a functionally uroselective alpha-1 blocker with a dual 5-alpha reductase inhibitor. Alfuzosin relaxes prostatic smooth muscle and decreases bladder outlet resistance without inhibiting alpha-1A subtype exclusively, preserving normal ejaculation in most men. Dutasteride halts DHT-mediated androgenic proliferation, reducing prostate volume. Indicated for symptomatic BPH with enlarged prostate gland.

Dutasteride Capsules (0.5mg) is a synthetic 4-aza-steroid dual inhibitor of both type 1 and type 2 5-alpha-reductase isoenzymes on the WHO Model List of Essential Medicines. It blocks the enzymatic intracellular conversion of testosterone to 5-alpha-dihydrotestosterone (DHT) in the prostate, skin, and liver, suppressing circulating DHT levels by >90% and intraprostatic DHT by >94%. This induces apoptotic involution of prostatic epithelial cells, progressively reducing total prostate volume by ~25% and reducing risk of urinary retention and TURP surgery. Indicated for treatment of symptomatic BPH in men with enlarged prostate.

Silodosin (4mg/8mg) and Dutasteride (0.5mg) Capsules is an advanced fixed-dose combination for Benign Prostatic Hyperplasia (BPH). Silodosin is an ultra-selective alpha-1A adrenergic receptor antagonist (>160-fold selectivity over alpha-1B receptors), providing targeted bladder neck and prostatic relaxation with minimal vascular hypotensive effects. Dutasteride blocks both 5-alpha reductase isoforms, permanently lowering circulating and intraprostatic DHT to shrink prostate gland tissue. Indicated for treatment of moderate-to-severe LUTS associated with prostatic enlargement.
