Pharmacodynamics and pharmacokinetics

The active component of the agent is a double inhibitor of the enzyme 5-alpha-reductase. The substance inhibits the conversion of testosterone to DHT by suppressing the activity of 5-alpha-reductase 1 and type 2. After all, dihydrotestosterone is responsible for the development of hyperplasia. Thus, the size of the prostate gland decreases, urination normalizes, the probability of cure without surgery is increased.
The higher the dose of the drug taken, the more it affects the production of DHT. Its maximum effect is achieved in one to two weeks, after the start of treatment.
The maximum concentration of the drug in the blood serum is reached approximately 1.5 hours after administration. Bioavailability is 60% (compared to intravenous administration). Eating does not affect the performance.
The drug has a very high degree of binding to plasma proteins, about 99%. About 11.5% of the active ingredient with a systematic long-term admission gets into the sperm.
In a living organism, Avodart is extensively metabolized. Excretion of 1-15% of the substance occurs through intestines in unchanged form, 74% make up 4 large metabolites, 5% - other small metabolites. Completely out of the body the drug is withdrawn about a month after the end of admission. However, even after 6 months, its insignificant amount can be detected in serum.
In elderly patients there was no significant change in any pharmacokinetic parameters. From this it follows that correction of the dose is not necessary.
