Prostagard vs Prostagard D - Key Differences
| Feature | Prostagard | Prostagard D |
|---|---|---|
| Active Ingredient(s) | Silodosin only | Silodosin + Dutasteride |
| Drug Class | Alpha-1 blocker (monotherapy) | Alpha-1 blocker + 5-alpha reductase inhibitor (combination) |
| Available Strengths | 4 mg, 8 mg | 4 mg/0.5 mg, 8 mg/0.5 mg |
| Manufacturer | Aristo Pharmaceuticals | Aristo Pharmaceuticals |
| Indication | BPH - symptom relief | BPH - symptom relief + prostate size reduction |
| Mechanism | Relaxes smooth muscle in prostate/bladder neck → improves urine flow | Silodosin relaxes muscle AND Dutasteride reduces DHT → shrinks prostate |
| Onset of benefit | Faster (days to weeks) | Silodosin effect is fast; Dutasteride takes 3-6 months to shrink prostate |
| Best suited for | Mild-to-moderate BPH, symptomatic relief | Moderate-to-severe BPH, larger prostates, long-term management |
Drug Details
Prostagard (Silodosin alone)
- Silodosin is a highly selective alpha-1A adrenoceptor blocker
- Relaxes smooth muscles in the prostate and bladder neck
- Improves urine flow rate and reduces urinary symptoms (frequency, urgency, weak stream, nocturia)
- Does NOT reduce prostate size
Prostagard D (Silodosin + Dutasteride)
- Adds Dutasteride, a dual 5-alpha reductase inhibitor (inhibits both type 1 and type 2)
- Dutasteride blocks conversion of testosterone to DHT, which is the primary driver of prostate enlargement
- The combination addresses both the functional (muscle tone) and structural (prostate volume) components of BPH
- Reduces risk of acute urinary retention and need for BPH-related surgery over the long term
When Each Is Used
- Prostagard alone: suitable for men with predominantly functional/obstructive urinary symptoms without significantly enlarged prostate
- Prostagard D: preferred when the prostate is significantly enlarged (typically >30-40 mL volume), PSA is elevated, or there is a higher risk of disease progression
Both are prescription-only medicines for adult males. Neither is indicated for prostate cancer treatment or prevention. Women (especially pregnant) must not handle Dutasteride-containing capsules due to risk of fetal harm.
