This product is an antifibrinolytic drug. It binds to the lysine binding sites on plasminogen and plasmin, inhibiting the binding of plasminogen to fibrin and preventing its activation, thereby inhibiting fibrinolysis; at high concentrations, it directly inhibits the activity of plasmin and achieves a hemostatic effect.

It has strong antibacterial activity against Staphylococcus, Streptococcus, Pneumococcus, Peptostreptococcus, Neisseria gonorrhoeae, Branhamella catarrhalis, Escherichia coli, Klebsiella, Proteus (Proteus mirabilis, Proteus vulgaris, Providencia rettgeri, Providencia anomala), Citrobacter, Enterobacter, and Haemophilus influenzae

This product is a mucolytic agent and a prodrug. Its molecular structure contains a blocked thiol group (-SH). It is transformed into an active metabolite containing free thiol groups through liver biotransformation to play a mucolytic role. Its mechanism of action may be mainly to break the disulfide bonds of mucin in bronchial secretions through metabolites containing free thiol groups, change its composition and rheological properties (reduce sputum viscosity), and thus facilitate sputum discharge. In addition, this product also has the effect of enhancing the function of mucociliary function.

Extract from the above information

The average molecular weight (Mw) should be 27500-39500. Its osmotic pressure is equal to that of plasma, which can maintain the balance between intravascular fluid and interstitial fluid, does not cause tissue dehydration and pulmonary edema, and has the effect of maintaining blood volume and raising blood pressure. Infusion of this product can lead to blood dilution, reduce blood viscosity, and thus improve microcirculation. This product has no significant effect on blood clotting time and platelet function, and only has a blood dilution effect.
