Pharmacological action

This product is a penicillin antibiotic. The antibacterial spectrum and action mechanism are the same as penicillin, which can kill sensitive bacteria in breeding period by inhibiting the synthesis of mucin in bacterial cell wall. This product has antibacterial activity against most gram-positive bacteria, some gram-negative bacteria (such as Haemophilus), spirochetes and actinomycetes, but most staphylococcus strains (more than 90%), including Staphylococcus aureus and coagulase-negative staphylococcus, can produce β -lactamase to inactivate this product by hydrolysis. The activity of this product against most sensitive bacteria is 2 ~ 5 times weaker than penicillin. Has no antibacterial effect on penicillinase-producing strains.
