2021年非那雄胺(保法止) 的价格及副作用

Finasteride tablets are mainly used to control prostatic hyperplasia and relieve symptoms such as difficulty urinating and urinary retention caused by prostatic hyperplasia. Finasteride can also be used to treat partial hair loss. It is a specific inhibitor of type II 5a-reductase, an intracellular enzyme that metabolizes testosterone into dihydrotestosterone. Today, let’s learn about the price and side effects of finasteride (Propecia) in 2021.

Finasteride tablets are currently covered by Category B medical insurance in China, which can reimburse part of the medical expenses. Patients in need can obtain foreign versions of the drug through domestic professional overseas medical service agencies (such as Medical Companion Travel). Due to the floating exchange rate and the price is not fixed, you can consult Medical Companion Travel Service for specific prices.

Clinical studies have shown that ≥1% of male patients treated with Propecia experience the following medication-related side effects: decreased libido and impotence. Postmarketing reported adverse events also include breast tenderness or enlargement, allergic reactions (including rash, itching, hives, and lip swelling), and testicular pain.

Finasteride is a synthetic steroid compound that is a specific inhibitor of the intracellular enzyme (type II 5α reductase) involved in the metabolism of the androgen testosterone into dihydrotestosterone. Finasteride has no affinity for the androgen receptor and has no androgenic, antiandrogenic, estrogenic, antiestrogenic, or progestational effects.

Finasteride's inhibition of type II 5α reductase can hinder the conversion of testosterone into the androgen dihydrotestosterone in peripheral tissues, causing a significant decrease in dihydrotestosterone concentrations in serum and tissues. Compared with placebo, it can increase the level of testosterone in the blood circulation by about 10-15%, but it is still within the physiological range. Finasteride can rapidly reduce the concentration of dihydrotestosterone in the serum and significantly reduce it within 24 hours after administration.

Long-term use of 1 mg of finasteride can be effective for a long time. As the time of taking is extended, hair loss can remain stable for a long time and can be improved to the greatest extent. Then some patients may have mild adverse reactions during the medication process. The incidence of such adverse reactions does not exceed 2%. For most friends, as the medication time is prolonged, the adverse reactions will be relieved and eliminated on their own.
