Fluconazole is a triazole broad-spectrum antifungal drug that inhibits the reproduction and growth of fungi by highly selectively inhibiting the demethylation of fungal cytochrome P-450 sterol C-14-alpha;, causing the accumulation of 14-alpha;-methyl sterol in fungi. It has antibacterial activity against Cryptococcus neoformans and Candida species, and is also effective against dermatitis blastomyces infections and coccidioides immitis infections (including intracranial infections); it is also effective against infections caused by capsular histoplasma in normal animals and immunosuppressed animals.

This product has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes and other Enterobacteriaceae, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often also has antibacterial activity against multidrug-resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella. It has antibacterial effect on most strains of Pseudomonas such as Pseudomonas aeruginosa. This product has antibacterial activity against methicillin-sensitive Staphylococci, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good antibacterial activity against Chlamydia trachomatis, Mycoplasma and Legionella.

It has high antibacterial activity against Gram-positive bacteria such as Staphylococcus (including penicillin-resistant strains) and Streptococcus. It also has good antibacterial activity against Gram-negative bacteria. It is an antibacterial drug. At high concentrations, it also has a bactericidal effect on highly sensitive bacteria. The mechanism of action is to bind to the 50S subunit of the ribosome of sensitive bacteria, prevent the extension of the peptide chain, and thus inhibit the protein synthesis of bacterial cells. There is no cross-resistance with chloramphenicol and tetracyclines, there is partial cross-resistance with macrolides, and there is complete cross-resistance with clindamycin.

1. Sodium hyaluronate is a linear polysaccharide that is widely present in the connective tissue matrix of vertebrates. Sodium hyaluronate can bind to fibronectin and accelerate the adhesion and extension of epithelial cells; sodium hyaluronate molecules can retain a large number of water molecules and have a good water retention effect. 2. Rabbit experiments suggest that topical application of sodium hyaluronate can promote the healing of corneal epithelial injuries to a certain extent. In vitro experiments suggest that sodium hyaluronate can accelerate the extension of conjunctival epithelial cells in cultured rabbit corneal slices and has the effect of preventing the drying of isolated rabbit conjunctival slices.

It is a selective beta-2 adrenergic receptor agonist. It can selectively act on the beta-2 adrenergic receptors of bronchial smooth muscle and has a strong bronchial dilation effect. At the dose for treating asthma, the stimulating effect on the heart is weak.
