Finasteride
Drugs For Hair Loss And Benign Prostatic Hyperplasia In MenUses of Finasteride
Finasteride is a 5-alpha reductase inhibitor used to treat prostate enlargement and hair loss in men.
It is commonly used for:
- Benign prostatic hyperplasia (BPH): Reduces the size of an enlarged prostate gland, easing urinary symptoms such as difficulty passing urine and frequent urination.
- Androgenic alopecia (male pattern hair loss): Slows hair loss and supports regrowth in men experiencing pattern baldness.
- Lower urinary tract symptoms: Helps relieve symptoms linked to an enlarged prostate, such as weak urine flow and incomplete bladder emptying, as prescribed by your doctor.
Side effects of Finasteride
- Problems with ejaculation
- Erectile dysfunction
- Low sexual desire
- Breast disorders or tenderness
How Finasteride works
- Finasteride belongs to a class of medicines called 5-alpha reductase inhibitors.
- It works by blocking an enzyme called 5-alpha reductase, which converts testosterone into a more potent hormone called dihydrotestosterone (DHT).
- In the prostate high DHT levels contribute to gland enlargement. By lowering DHT, Finasteride helps shrink the prostate, easing pressure on the urethra and improving urine flow.
- On the scalp reduced DHT levels help slow the process that leads to pattern baldness, supporting hair regrowth over time.
