To treat gynecological inflammation. The efficacy of the flower red tablets clears heat and relieves dampness, removes blood stasis and relieves pain. It is used for damp-heat type of women's underbearing, irregular menstruation, dysmenorrhea, and gynecological inflammation such as endometritis, adnexitis, pelvic inflammation, and so on. Metronidazole has powerful antibacterial effects against most anaerobic bacteria. The antimicrobial spectrum includes the genera Mycobacterium fragilis and other Mycobacterium species, Clostridium perfringens, Clostridium perfringens, Fusobacterium funiculosum, Verrucomicrobium, Digestive Coccus and Digestive Streptococcus, and so on. Its bactericidal concentration is slightly higher than that of bacteriostatic solutions. The bactericidal mechanism of metronidazole has not been fully elucidated, and the nitroreductase of anaerobic bacteria plays an important role in the energy metabolism of sensitive strains. 1. With a broad-spectrum anti-anaerobic bacteria and antiprotozoal effects, clinical mainly used for the prevention and treatment of infections caused by anaerobic bacteria, such as respiratory tract, digestive metronidazole tablets, abdominal and pelvic pus infections, skin and soft tissues, bone and bone joints and other parts of the infection and fragile mimic bacillus caused by endocarditis, septicemia and meningitis, etc., in addition to being widely used in the prevention and treatment of oral anaerobic bacteria infections. 2. The nitro of this product is reduced to amino group in anaerobic environment and shows anti-anaerobic effect, but it is ineffective against aerobic bacteria or parthenogenetic aerobic bacteria. It has good antimicrobial effect on the following anaerobic bacteria: ①Anabacterium genus, including Anabacterium fragilis; ②Clostridium genus; ②Clostridium genus, including Tetanus bacillus; ④Part of fungi; ⑤Digestive coccus and Digestive Streptococcus and so on. 3. Oral absorption is good, bioavailability (F) more than 80%, 250mg, 500mg oral and 2000mg, 1 ~ 2 hours serum drug concentration reaches the bee, respectively, 6μg / ml, 12μg / ml and 40μg / ml. 15mg / kg of static drip of this product, and every 6 hours thereafter 7.5mg / kg, plasma drug concentration of metronidazole tablets to reach a steady state peak concentration of 25μg / ml, the subsequent drip 7.5mg / kg, the peak concentration of metronidazole tablets to reach a steady state, the peak concentration of metronidazole tablets is 25μg / ml. The peak concentration of plasma metronidazole tablets at steady state is 25μg/ml, and the trough concentration can be up to 18μg/ml. 4. The product is widely distributed in the body, and can enter into saliva, breast milk, pus of hepatic abscess, and also enter into the cerebrospinal fluid (the concentration of the cerebrospinal fluid of the normal people can reach 50% of the blood). In the body, it is metabolized by oxidation of the side chain or by binding to glucuronic acid, while 20% of the drug is not metabolized. Its metabolites are also active. Metronidazole and its metabolites are excreted in large quantities by urine (60%-80% of the total) and in small quantities by feces (6%-15%). t1/2 is about 8 hours. 5. It is mainly used for the treatment or prevention of systemic or local infections caused by the above anaerobic bacteria, such as anaerobic infections in the abdominal cavity, digestive tract, female reproductive system, lower respiratory tract, skin and soft tissues, bones and joints, etc. It is also effective in sepsis, endocarditis, meningeal infections as well as colitis caused by the use of antibiotics. It is also effective in sepsis, endocarditis, meningeal infections, and colitis caused by antibiotic use. It is often used in combination with tetanus antitoxin (TAT) in the treatment of tetanus. It is also used for oral anaerobic infections. 6. Antiprotozoa Amebiasis Trichomoniasis Trichomonas vaginalis Giardia lamblia and other parasitic trichomonads and flagellates in the lumen.
