This product is an intravenous alprostadil preparation with lipid microspheres as drug carriers. Due to the encapsulation of lipid microspheres, alprostadil is not easy to be inactivated. In addition, this product has the targeting characteristics of being easily distributed to damaged blood vessels, thereby exerting the effects of this product in dilating blood vessels and inhibiting platelet aggregation.

The main pharmacological action is to relax vascular smooth muscle. Nitroglycerin releases nitric oxide (NO), which is the same as endothelial relaxing factor, activating guanylate cyclase, increasing cyclic guanosine monophosphate (cGMP) in smooth muscle and other tissues, leading to dephosphorylation of myosin light chain, regulating the contractile state of smooth muscle, and causing vasodilation.

Aminoglycoside antibiotics have antibacterial effects on most Enterobacteriaceae, Pseudomonas aeruginosa, Acinetobacter, Alcaligenes, meningococci, gonococci, influenza bacilli, Yersinia, Campylobacter fetus, Mycobacterium tuberculosis and some Mycobacterium. Its mechanism of action is to act on the 30S subunit of bacterial ribosomes and inhibit bacterial protein synthesis. Combination with semi-synthetic penicillins or cephalosporins often produces synergistic antibacterial effects.

It can inhibit platelet aggregation and prevent thrombosis. It can also counteract vascular damage caused by 5-hydroxytryptamine and bradykinin, increase capillary resistance, reduce capillary permeability, and prevent edema caused by increased vascular permeability.

This product is an immunomodulatory drug. It has the function of regulating and enhancing the cellular immune function of the human body. It can promote the maturation of T lymphocytes in the peripheral blood after mitogen activation, increase the secretion of various lymphokines (such as α, γ interferon, interleukin 2 and interleukin 3) after T cells are activated by various antigens or mitogens, and increase the level of lymphokine receptors on T cells. It also enhances the response of lymphocytes by activating T4 helper cells. In addition, this product may affect the chemotaxis of NK precursor cells, which become more cytotoxic after exposure to interferon. Therefore, this product has the function of regulating and enhancing the cellular immune function of the human body. This product is an immune bidirectional modulator. It has the function of inducing and promoting the differentiation, maturation and activation of T lymphocytes and their subsets, regulating T lymphocytes.
