[Taboo] The product and cephalosporins have a history of allergic reactions are prohibited.
[Precautions] 1. The following patients take drugs carefully
(1) Patients with a history of allergy to penicillin antibiotics;
(2) I or my parents and brothers have patients who are prone to allergic symptoms such as bronchial asthma, rash, urticaria, etc.
(3) Patients with severe renal dysfunction (continuous increase of blood drug concentration may occur);
(4) Elderly Patients (Decline in Physiological Function, side effects are easy to occur; Sometimes vitamin K deficiency and bleeding tendency);
(5) people with poor oral feeding or intravenous nutrition, and people with poor general state (sometimes vitamin K deficiency can be caused, so careful observation should be made);
2, because shock reaction may occur, so detailed consultation is required. It is recommended to do skin allergy test before injection. First aid should be done in advance in the event of shock.
3, the use of this product, the best regular liver function, kidney function, blood and other tests.
4. Interference to diagnostic reagents: In addition to the reaction of urine sugar test strip (TES-tape), false positive reaction may occur when urine sugar test is carried out with Banns reagent, Flynn reagent and Clinitest (sheet reagent containing copper sulfate), and direct antiglobulin (Coombs) test is positive, please pay attention.

[Pharmacology and Toxicology] Pharmacological Effects
Cefmenoxime is a semi-synthetic cephalosporin broad-spectrum antibiotic that achieves bactericidal effects by inhibiting the biosynthesis of bacterial cell walls. This product has a strong antibacterial effect on gram-negative bacteria due to its good extracellular membrane permeability, stability to β-lactamase, and strong affinity to penicillin binding proteins (PBPs)1A, 1B and 3, which has a strong barrier to the formation of cell wall mucin cross-linking.
In vitro tests show that this product has an effect on both gram-positive and gram-negative bacteria. The antibacterial activity of Gram-positive bacteria was stronger than that of cefotiam (CTM) and cefazolin (CEZ) in terms of Streptococcus pyogenes and Streptococcus pneumoniae. It has strong antibacterial power against digestive cocci and digestive streptococcus. The antibacterial power to Gram-negative bacteria was slightly stronger than CTM and much stronger than CEZ in terms of E. coli and pneumoniae. The antibacterial force against influenza bacilli, Proteus, Serratia marcescens, Citrobacter, and intestinal bacteria was stronger than CTM, and much stronger than CEZ. In addition, it also shows strong antibacterial power to Bacteroides.
Toxicology study Reproductive toxicity: Animal experiments showed that in rats, rabbits and monkeys during the organ formation period of administration, each administration group of rabbits had female rabbit death or abortion, but all kinds of animals had no teratogenic effect. There was no obvious abnormality in general reproductive toxicity test and perinatal reproductive toxicity test in rats. [Pharmacokinetics] According to literature data, the peak blood drug concentration can reach 50.9mg/L and 135.7mg/L respectively after a single intravenous infusion of 0.5g and 1g of this drug in adults with normal renal function, and 75mg/L and 125mg/L respectively after a single intravenous infusion of 0.5g and 1g of cefmenoxime. The serum elimination half-life of this product is about 1 hour. It is well distributed in various tissues and body fluids after administration. It can also cross the blood-brain barrier. The drug is mainly excreted through the kidney. After an intravenous injection or intravenous drip of 0.5g, 1g and 2g of the drug in adults (with normal renal function), the excretion rate in urine within 6 hours is 60-82%. In addition, the urine drug concentration after 1g of intravenous drip was about 4400 μg/L for 0-2 hours, about 750 μg/L for 2-4 hours, and about 120 μg/L for 4-6 hours. Children (with normal renal function) had the same urinary excretion rate at 6 hours after a single intravenous injection or intravenous drip of 10, 20, and 40 mg/kg as adults.
[Storage] Shaded, airtight, and stored in a cool and dry place (not more than 20 ℃).
