Finast
Medical expert of the article
Last reviewed: 04.07.2025

Finast has an anti-anthrogenic effect and affects metabolic processes within the prostate tissue.
The effect of finasteride is based on the inhibition of the therapeutic activity of the enzyme 5-α-reductase. As a result, the conversion of testosterone into an active androgenic hormone - 5-dihydrotestosterone - is prevented. The values of this androgen are reduced both in the blood and in the prostate, thereby preventing the growth of tissues of this gland.
The therapy results in a reduction in the size of the prostate and reduces the intensity of the symptoms of the disease.
