Metronidazole Vitamin B6 Tablets

Metronidazole has a strong antibacterial effect on most anaerobic bacteria, but has no effect on aerobic bacteria and facultative anaerobes. The antibacterial spectrum includes Bacteroides fragilis and other Bacteroides, Fusobacterium, Clostridium perfringens, Eubacterium, Veillonella, Peptococcus and Peptostreptococcus. Actinomycetes, Lactobacillus and Propionibacterium are resistant to this product. Its bactericidal concentration is slightly higher than the inhibitory concentration. In addition, it has a strong killing effect on amoeba and Trichomonas. The bactericidal mechanism of metronidazole has not been fully elucidated. The nitroreductase of anaerobic bacteria plays an important role in the energy metabolism of sensitive strains. The nitro group of this product is reduced to a cytotoxin, which acts on the DNA metabolism process of bacteria and promotes cell death. Resistant bacteria often lack nitroreductase and are therefore resistant to metronidazole. Vitamin B6 can reduce the adverse reactions of metronidazole.

Each tablet contains 0.20g of metronidazole and 0.02g of vitamin B6.

1 This product can inhibit the metabolism of warfarin and other oral anticoagulants, enhance their effects, and cause the prothrombin time to be prolonged. 2 The simultaneous use of drugs that induce liver microsomal enzymes, such as phenytoin sodium and phenobarbital, can enhance the metabolism of this product, reduce the blood concentration, and slow down the excretion of phenytoin sodium. 3 The simultaneous use of drugs that inhibit the activity of liver microsomal enzymes, such as cimetidine, can slow down the metabolism and excretion of this product in the liver, and prolong the serum half-life of this product. The dosage should be adjusted according to the results of blood drug concentration determination. 4 This product interferes with the metabolism of disulfiram. The combination of the two can cause mental symptoms after drinking. Therefore, those who have used disulfiram within 2 weeks should not use this product again.

Keep away from light and store in sealed container.
