It has high activity against protozoa and anaerobic bacteria, and can inhibit most anaerobic bacteria; microaerophilic bacteria and Helicobacter pylori are sensitive to it; the mechanism of anti-amoeba is to inhibit its redox reaction, break the nitrogen chain of the protozoa, and thus kill the protozoa. The mechanism of action includes reduction to cytotoxicity, acting on the bacterial DNA metabolism process, and interfering with the redox reaction of the protozoa.

This product is a broad-spectrum semi-synthetic penicillin, which has antibacterial effects on hemolytic streptococci, viridans streptococci, pneumococci, penicillin G-sensitive Staphylococcus aureus, gonococci, Haemophilus influenzae, enterococci, Salmonella, Salmonella typhi and Proteus. This product has no effect on Staphylococcus aureus that produces penicillinase. Bacteria have complete cross-resistance to this product and ampicillin.

Nucleoside antiviral drugs. Competitively inhibit DNA polymerase and incorporate into the DNA of viruses and host cells, thereby inhibiting DNA synthesis. The inhibitory effect on viral DNA polymerase is stronger than that on host cell polymerase. In animal experiments, this product has teratogenic, carcinogenic, immunosuppressive effects and reproductive system toxicity.

This product is a broad-spectrum antifungal drug. Its mechanism of action is to inhibit the synthesis of cell membranes. It has antibacterial effects on dermatophytes and Candida.
