非那雄胺片5mg一片的价格是多少钱一盒？

Finasteride is a 5α-reductase inhibitor. It is a specific inhibitor of the intracellular enzyme type II 5α-reductase during the metabolism of the androgen testosterone into dihydrotestosterone. Finasteride is mainly used to treat prostatic hyperplasia and to treat hair loss in men.

Orally administered to adults. BPH: 5 mg once a day. Male androgenetic alopecia: The recommended dose is 1 mg once a day. Finasteride (5 mg) has a bioavailability of 63% after a single oral dose, and its bioavailability is not affected by food. The plasma concentration reaches the peak 1 to 2 hours after taking the drug, and the Cmax is 37ng/mL.

Dosage for the elderly: In patients over 70 years old, the elimination half-life is slightly prolonged and the clearance rate is reduced, but this has no practical clinical significance, so there is no need to reduce the dosage of the drug in the elderly. 

Renal Impairment: No dosage adjustment is required in patients with renal impairment. In patients with chronic renal dysfunction (creatinine clearance in the range of 9-55 ml/min), the AUC, Cmax and t1/2 after a single dose of 14C-finasteride are no different from healthy volunteers. Some metabolites that are normally excreted by the kidneys are excreted in the feces. Thus there is an increase in fecal excretion of metabolites and a corresponding decrease in urinary excretion.

Hepatic insufficiency: No pharmacokinetic studies have been conducted in patients with hepatic insufficiency, but finasteride is mainly metabolized by the liver and should be used with caution in patients with hepatic insufficiency.

Youth or children under 18 years of age: No pharmacokinetic studies have been conducted, so finasteride should be used with caution in these patients.
