Pharmacological action

The drug for the treatment of benign prostatic hyperplasia. The action of the drug is to reduce the enlarged prostate gland. Finasteride is a specific inhibitor of 5-α-reductase, which transforms testosterone into more active 5-α-dihydrotestosterone. The suppression of dihydrotestosterone formation is accompanied by a decrease in prostate size, increase in maximum urine flow rate and a decrease in symptoms of urinary tract obstruction.

With continued application of a statistically significant effect is recorded after 3 months (a decrease of cancer). After 4 months there is an increase of maximum flow rate of urine. After 7 months, a decrease in overall symptoms and symptoms of urinary tract obstruction. In 50% of patients with clinical symptoms disappear within 12 months.



Finasteride is rapidly and almost completely absorbed from the gastrointestinal tract. Bioavailability - 80%, independent of food intake. Cmax plasma levels achieved after 1-2 hours


Binding to plasma proteins - 90%. Finasteride penetrates the tissue and body fluids - is found in the ejaculate.


Outputs in the form of metabolites in the urine (39%) and feces (57%). T1 / 2 is 6-8 hours long (3-7 months) to use the drug in a dose of 5 mg / day reduces the concentration of 5-alpha-dihydrotestosterone in the serum of 70%.

benign prostatic hyperplasia (reduction in the size of the prostate gland, increase the maximum speed of the outflow of urine, reducing the risk of acute urinary retention requiring catheterization or surgical intervention).

Dosage regimen

Precautions should use the drug in patients with hepatic insufficiency.

Pregnancy and lactation

Women of childbearing age and pregnant women should avoid contact with the drug (especially touching shredded or lost the integrity of the tablets Alfinala) because the drug has teratogenic effects (the ability to inhibit the conversion of testosterone into DHT can cause a violation of sex organs in male fetus).

Patients with large amounts of residual urine and / or sharply reduced current urine must be closely monitored for possible development of obstructive uropathy. Before starting therapy it is necessary to exclude diseases that contribute to the progression of benign prostatic hyperplasia: prostate cancer, stricture urethra, hypotension bladder, innervation of the bladder, prostate infection.

For early detection of prostate cancer during therapy Alfinalom should undertake regular screening of patients, because applying Alfinala may reduce prostate-specific antigen (by 41% and 48%, respectively, at 6 and 12 th month of admission).
