Tinidazole injection
Function and Efficacy
This product has high activity against protozoan anaerobic bacteria. It has antibacterial activity against Bacteroides fragilis and other Bacteroides, Clostridium, 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 nitroammonia of this product is reduced to a cytotoxin, thereby acting on the DNA metabolism process of bacteria and promoting bacterial death. 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 amino chain of the protozoa, and thus kill the protozoa.

Appearance
This product is a colorless or almost colorless clear liquid.
Indication
1. Used for various anaerobic infections, such as sepsis, osteomyelitis, abdominal infection, pelvic infection, lung and bronchial infection, sinusitis, skin cellulitis, oral infection and postoperative wound infection; 2. Used for preoperative preventive medication for colorectal surgery, gynecological surgery and oral surgery.
Usage and Dosage
Intravenous drip. 1. Infections caused by anaerobic bacteria: 0.8g, once a day, intravenous drip slowly, generally 5-6 days, or determined according to the condition. 2. Prevention of postoperative anaerobic infection: total amount 1.6g, once or twice intravenous drip, the first time before surgery: 2-4 hours, the second time during surgery or within 12-14 hours after surgery.
Adverse Reactions
Adverse reactions are rare and mild, mainly nausea, vomiting, upper abdominal pain, decreased appetite and metallic taste in the mouth, headache, dizziness, itchy skin, rash, constipation and general discomfort. In addition, there may be angioedema, neutropenia, disulfiram reaction and dark urine. Mild phlebitis at the infusion site is occasionally seen. High doses can also cause epileptic seizures and peripheral neuropathy.
Precautions
1. It is contraindicated for patients who are allergic to this product or azole drugs, as well as those with active central nervous system diseases and blood diseases; 2. It is used with caution by pregnant women; 3. It is contraindicated for patients under 12 years old.
Special Population Medication
Precautions for children: It is contraindicated for patients under 12 years old. Precautions for pregnancy and lactation: It is contraindicated for women within three months of pregnancy and lactating women. Precautions for the elderly: Due to decreased liver function, the pharmacokinetics of this product may change when used in the elderly, and blood drug concentrations need to be monitored.
Drug Interactions
1. This product can inhibit the metabolism of warfarin and other oral anticoagulants, enhance their effects, and cause the prothrombin time to prolong. 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 the blood drug concentration, and slow 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 serum elimination half-life (t1/2β) 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, patients who have used disulfiram within 2 weeks should not use this product again. 5. This product can interfere with the determination results of aminotransferase and lactate dehydrogenase, and can reduce the levels of cholesterol and triglycerides.
