This product can inhibit viral DNA and RNA polymerase, thereby inhibiting viral reproduction. On human embryonic kidney cells, 1% concentration has a significant inhibitory effect on DNA viruses (adenovirus, herpes virus) and RNA viruses (echovirus), and has an inhibitory effect on all stages of the viral proliferation cycle. It has no direct effect on free viral particles.

This product is a fluoroquinolone antibacterial drug with a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacteria. It has good antibacterial activity against the following bacteria in vitro: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes and other Enterobacter species, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. Norfloxacin also has antibacterial activity against multi-drug resistant bacteria in vitro. It also has good antibacterial effects on penicillin-resistant Neisseria gonorrhoeae, Haemophilus influenzae and Moraxella catarrhalis. Norfloxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.

This product is a chloramphenicol antibiotic. It has a broad-spectrum antimicrobial effect in vitro, including aerobic Gram-negative and Gram-positive bacteria, anaerobes, Rickettsia, spirochetes and Chlamydia. It has bactericidal effects on the following bacteria: Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. It only has antibacterial effects on the following bacteria: Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic Streptococcus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Salmonella paratyphi, Shigella, Bacteroides fragilis and other anaerobic bacteria. The following bacteria are usually resistant to chloramphenicol: Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus and Enterococcus. This product is an antibacterial agent. Chloramphenicol is fat-soluble and enters bacterial cells by diffusion, and reversibly binds to the 50S subunit of the bacterial ribosome, which blocks the growth of the peptide chain (possibly due to the inhibition of the action of transpeptidase), thereby inhibiting the formation of the peptide chain and preventing protein synthesis.

Anti-inflammatory and anti-allergic effects, can inhibit the proliferation of connective tissue, reduce the permeability of capillary walls and cell membranes, reduce inflammatory exudate, and inhibit the formation and release of histamine and other toxic substances

This product is an adrenal cortex hormone drug. It has anti-inflammatory and anti-allergic effects, can inhibit the proliferation of connective tissue, reduce the permeability of capillary walls and cell membranes, reduce inflammatory exudate, and inhibit the formation and release of histamine and other toxic substances.

It is an azole antifungal drug, and has antibacterial and bactericidal effects on dermatophytes, yeasts (Candida, Pityrosporum, Torulopsis, Cryptococcus), dimorphic fungi and Fungi; except for Entomophthora, it has weaker effects on Aspergillus, Schenckia, some Phaeochromocytaceae, and Mucor. The main mechanism of action is to highly selectively interfere with the activity of fungal cytochrome P-450, thereby inhibiting the biosynthesis of ergosterol on the fungal cell membrane.

It is a powerful external corticosteroid with rapid effects, strong capillary contraction and anti-inflammatory effects.

Ketoconazole is an azole antifungal drug. It has antibacterial and bactericidal effects on dermatophytes, yeasts (Candida, Pityrosporum, Torulopsis, Cryptococcus), dimorphic fungi and Fungi; except for Entomophthora, it has weaker effects on Aspergillus, Schenckia, some Phaeochromocytaceae and Mucor. The mechanism of action of ketoconazole is mainly to highly selectively interfere with the activity of fungal cytochrome P-450, thereby inhibiting the biosynthesis of ergosterol on the fungal cell membrane. Clobetasol propionate is a potent topical corticosteroid. It acts quickly and has strong capillary constriction and anti-inflammatory effects.
