Tinidazole Sodium Chloride Injection

This product has high activity against protozoa and anaerobic bacteria. It has antibacterial activity against Bacteroides fragilis, Fusobacterium, Clostridium, Peptococcus, Peptostreptococcus, Veillonella and Gardnerella, and a concentration of 2-4 mg/L can inhibit most anaerobic bacteria; microaerophilic bacteria and Helicobacter pylori are sensitive to it; the MIC for Trichomonas vaginalis is similar to that of metronidazole, and its metabolites are more active against Gardnerella than metronidazole. The mechanism of action of this product 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 the death of bacteria. Resistant bacteria often lack nitroreductase and are resistant to this product. The mechanism of this product against amoeba is to inhibit its redox reaction, break the nitrogen chain of the protozoa, and thus kill the protozoa.

The main ingredient of this product is tinidazole. Its chemical name is 2-methyl-1-[2-(ethylsulfonyl)ethyl]-5-nitro-1H-imidazole. Molecular formula: C8H13N3O4S Molecular weight: 247.28

This product is a colorless or almost colorless clear liquid.

Used for various anaerobic infections, such as sepsis, osteomyelitis, abdominal infection, pelvic infection, lung and bronchial infection, pneumonia, sinusitis, skin cellulitis, oral infection and postoperative wound infection; used for preoperative preventive medication for colorectal surgery, gynecological surgery and oral surgery.

Intravenous drip. 1 Anaerobic infection: 0.8g once, once a day, intravenous drip slowly, generally 5 to 6 days, or according to the condition. 2 Prevention of postoperative anaerobic infection: total amount 1.6g, drip once or twice, the first time 2 to 4 hours before surgery, the second time during surgery or within 12 to 24 hours after surgery.

Adverse reactions are rare and mild, mainly nausea, vomiting, upper abdominal pain, loss of appetite and metallic taste in the mouth, headache, dizziness, itchy skin, rash, constipation and general discomfort.

Precautions for children: It is forbidden for patients under 12 years old. Precautions for pregnancy and lactation: This product can pass through the placenta and quickly enter the fetal circulation. Animal experiments have found that intraperitoneal administration is toxic to the fetus. Oral administration is non-toxic. There is no sufficient and strict control observation on the effect of this product on the fetus, so pregnant women should only use this product when there is a clear indication, but it should be banned in the first 3 months of pregnancy. Patients who are more than three months pregnant should use it with caution or follow the doctor's advice after fully weighing the pros and cons. The concentration of this product in breast milk is similar to that in blood. Animal experiments show that this product has a carcinogenic effect on young mice, so it is not recommended for lactating women. If the drug must be used, breastfeeding should be suspended, and breastfeeding can be resumed 3 days after the end of the treatment. Precautions for the elderly: Due to decreased liver function in the elderly, the pharmacokinetics of this product are changed when it is used, and the blood concentration needs to be monitored.

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 When used in combination with drugs that induce liver microsomal enzymes such as phenytoin sodium and phenobarbital, it can enhance the metabolism of this product, reduce blood drug concentration, and slow down the excretion of phenytoin sodium. 3 When used in combination with drugs that inhibit the activity of liver microsomal enzymes such as cimetidine, it can slow down the metabolism and excretion of this product in the liver, prolong the blood elimination half-life (t1/2b) of this product, and the dosage should be adjusted according to the results of blood drug concentration determination. 4 This product interferes with the metabolism of disulfiram. When the two are used together, patients may experience mental symptoms after drinking. Therefore, those who have used disulfiram within 2 weeks should not use this product again. 5 This product can interfere with the results of serum aminotransferase and lactate dehydrogenase determinations, and can reduce cholesterol and triglyceride levels.

Keep away from light, tightly closed, in a cool place.
