Mucolytics can increase the secretion of respiratory mucosal serous glands, reduce mucous gland secretion, reduce sputum viscosity, promote the secretion of pulmonary surfactant, increase bronchial ciliary movement, and make sputum easier to cough up.

Selective beta-receptor agonists relax bronchial smooth muscles, enhance ciliary movement, dissolve mucus, and promote sputum discharge

Lactulose is not absorbed in the small intestine, and only a small part of the acidic metabolites produced by its decomposition in the colon are absorbed. This leads to increased osmotic pressure in the intestinal cavity, retention of water and electrolytes, increased intestinal volume, mechanical stimulation to the intestinal wall, and chemical stimulation from the acidic metabolites, resulting in laxative effects.

This product belongs to the 4-nitrogen steroid hormone compound, which is a specific type II 5α-reductase competitive inhibitor. It inhibits the conversion of peripheral testosterone into dihydrotestosterone and reduces the level of dihydrotestosterone in the blood, prostate, skin and other tissues. The growth, development and benign hyperplasia of the prostate depend on dihydrotestosterone. Finasteride inhibits prostate hyperplasia and improves the related clinical symptoms of benign prostatic hyperplasia by reducing the level of dihydrotestosterone in the blood and prostate tissue.
