It depletes the norepinephrine storage in the peripheral sympathetic nerve terminals, and also depletes the catecholamine and 5-hydroxytryptamine storage in the brain, heart and other organs. The blood pressure reduction is mainly peripheral, the peripheral vascular resistance is reduced, the heart rate is slowed down, and the cardiac output is reduced, thereby lowering the blood pressure.

It has a direct relaxant effect on respiratory smooth muscle, partly by inhibiting phosphodiesterase to increase intracellular cAMP content, and partly as a result of the release of endogenous adrenaline and norepinephrine; as a purine receptor blocker, it can counteract the contractile effect of adenine and other substances on the respiratory tract; it can enhance the contractility of the diaphragm and improve respiratory function.

It is effective against schistosomes, tapeworms, cysticercosis, Clonorchis sinensis, Paragonimus thoracis, and Fasciola gingivalis. It has two main pharmacological effects on the worm: 1. The muscles of the worm undergo tonic contraction and produce spastic paralysis; 2. The cortex of the worm is damaged and the host immune function is involved. In addition, praziquantel can also cause secondary changes, depolarizing the surface membrane of the worm, significantly reducing the activity of cortical alkaline phosphatase, inhibiting the uptake of glucose, depleting endogenous glycogen, and inhibiting the synthesis of nucleic acid and protein in the worm.

It can counteract the capillary dilation caused by allergic reactions (histamine), reduce the permeability of capillaries, and alleviate the symptoms of runny nose, nasal congestion, sneezing, etc. caused by allergic rhinitis

As one of the important components of coenzyme, it plays a synergistic role

It can inhibit the synthesis of prostaglandins and has antipyretic and analgesic effects

This product is a mucolytic agent that can increase the secretion of serous glands in the respiratory mucosa and reduce the secretion of mucous glands, thereby reducing sputum viscosity, promoting the secretion of pulmonary surfactant, increasing bronchial ciliary movement, and making sputum easier to cough up.
