It can form a thin film on the surface of damaged gastric mucosa, thereby resisting the invasion of gastric acid on the mucosa and protecting the gastric mucosa. In addition, sucralfate can absorb pepsin and neutralize gastric acid, but the effect is weak.

This product is a compound of aminopyrine and sodium sulfite. It is easily soluble in water and has faster and stronger antipyretic and analgesic effects than aminopyrine.

It combines with adenosine triphosphate to form vitamin B1 pyrophosphate (thiamine diphosphate, cocarboxylase), which is a coenzyme necessary for carbohydrate metabolism; it can inhibit the activity of cholinesterase. When it is deficient, cholinesterase activity is enhanced, acetylcholine hydrolysis is accelerated, causing nerve impulse conduction disorders and affecting gastrointestinal and myocardial function.

This product can inhibit the synthesis of prostaglandins and has antipyretic, analgesic and anti-inflammatory effects.

This product belongs to the macrolide antibiotics. It is antibacterial to Staphylococcus (except methicillin-resistant strains), all groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. are also sensitive to this product. This product also has antibacterial effects on various anaerobic bacteria except Bacteroides fragilis and Fusobacterium. It also has inhibitory effects on Legionella, Campylobacter fetus, some spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on some bacteria at high concentrations. It can penetrate the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor site (P site), blocking the transfer RNA (t-RNA) from binding to the P site, and also blocking the displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis.
