Florfenicol is also known as fluoromethylsulfonomycin and fluprofen. It is a broad-spectrum antibiotic specially used for amide alcohols. Monofluoro derivatives formed by fluorination of thiamphenicol are very soluble in dimethylformamide, methanol and water. Therefore, through in-depth research and analysis of flufenicol bulk drug and improvement of production process, Huizhong veterinary medicine has developed a new high water-soluble process of automatic dissolution in water, flufenicol powder puldekang.
Function and use
Florfenicol has the advantages of broad spectrum, high efficiency, low toxicity, excellent absorption, wide distribution in the body and no aplastic anemia. It is effective against most Gram-negative bacteria, Gram-positive bacteria, some mycoplasmas and some strains resistant to chloramphenicol, thiamphenicol, oxytetracycline, sulfonamide or ampicillin, and its antibacterial activity is better than chloramphenicol and Thiamphenicol. In vitro bacteriostatic test showed that the product could inhibit bacteria at low concentration and slowly sterilize at high concentration; Its MBC value to most bacteria is equal to MIC value or 2 ~ 4 times of MIC value, and all have different degrees of post antibiotic effect.
Florfenicol is absorbed rapidly and widely distributed in the body. The drug concentration in the liver and kidney is higher than that in the blood; The concentration in lung, heart, spleen, pancreas and intestine was equivalent to that in blood; The blood drug concentration in cerebrospinal fluid is low, only 1 / 4 ~ 1 / 2 of the blood drug concentration. This indicates that this product is suitable for treating systemic infectious diseases.
Product features
1. Florfenicol is a broad-spectrum and efficient antibiotic specially used for animals with low toxicity.
2. Oral administration has excellent absorption, wide distribution in the body and no aplastic anemia.
3. Strong antibacterial activity, bacteriostasis at low concentration and slow sterilization at high concentration.
4. It is suitable for treating systemic infectious diseases.
Product advantages
1. High purity levoflofenicol raw material has no residue of chloramphenicol and thiamphenicol, strong antibacterial activity, high safety, low toxic and side effects and low drug resistance.
2. New supramolecular inclusion technology is adopted to avoid the interaction between florfenicol and special excipients, increase the solubility and dissolution of florfenicol, adjust the release rate, perfectly solve the problem of water solubility, easy dissolution, no precipitation, no blocking of drinking water system and less possible loss.
3. It has stable chemical properties, improves the bioavailability of drugs, reduces the toxic and side effects of drugs, and has a definite effect in clinical application.
clinical application
