This product is a new type of anti-microtubule drug. It promotes tubulin polymerization, inhibits depolymerization, maintains tubulin stability, and inhibits cell mitosis. In vitro experiments have shown that paclitaxel has a significant radiosensitization effect, which may be to stop cells in the G2 and M phases that are sensitive to radiotherapy. Paclitaxel is a mitotic inhibitor or spindle poison. It has a different mechanism of action from the commonly used chemotherapy drugs. It induces and promotes the assembly of microtubules. Paclitaxel has the effect of polymerizing and stabilizing microtubules, causing rapidly dividing tumor cells to be firmly fixed in the mitotic stage, blocking the replication of cancer cells and causing them to die.

Acts on dihydrofolate synthase, interfering with the first step of folic acid synthesis, and has a synergistic antibacterial effect when used in combination with trimethoprim

It acts on the second step of folic acid anabolism, selectively inhibits the action of dihydrofolate reductase, and has a synergistic antibacterial effect when used in combination with sulfadiazine

This product is a dried yeast body, rich in B vitamins, and has an auxiliary therapeutic effect on indigestion.

This product is a mucus regulator, which mainly acts on the secretion of bronchial glands, increasing the secretion of low-viscosity salivary mucin and reducing the production of high-viscosity fucoxomucin, thereby reducing the viscosity of sputum and making it easier to cough up. It takes effect quickly after oral administration, and obvious therapeutic effects can be seen within 4 hours of taking it.
