Proscar belongs to a group of drugs that treat benign prostatic hypertrophy.
Finasteride is the main active component of the drug, which is a testosterone 5-alpha reductase inhibitor (type II). This substance is an intracellular enzyme, due to which testosterone is converted into the androgen dihydrotestosterone (the main cause of this type of prostatic hyperplasia), which is a more active androgen.
Finasteride has the property with a high degree of effectiveness to reduce the level of dihydrotestosterone, both circulating and intraprostatic. The use of this drug helps to reduce urinary retention in acute form by more than half after 4 years of treatment. The risks of surgery are reduced by 50% over the same period.
Also, there is a regression of the size of the prostate by 1/5, the rate of urine outflow increases significantly. The risks of further progression of this disease are reduced by 67%.
Studies in the United States have shown that regular use of this drug in benign prostatic hypertrophy reduces the risk of prostate cancer by 25%.
