?Pharmaco-toxicological?
This product of Gram-positive bacteria and gram-negative bacteria have a broad-spectrum antibacterial activity, especially for E. coli, Klebsiella spp, Haemophilus influenzae, Proteus mirabilis, and vulnerability are Bacteroides has a strong antibacterial effect. Its mechanism of β-lactam antibiotic penicillin is usually the role of point-binding protein showed a strong affinity, inhibit cell wall synthesis, and peptide-binding inhibiting peptidoglycan binding and to promote the bacteriolytic lipoprotein in a short period of time showed a strong bactericidal. This product is a view of the proliferation of bacteria and have shown stability in the early period of antimicrobial activity, which is lower than the concentration of MIC also has bactericidal action, a short period of time bacteriolysis.  In vivo antibacterial MIC forecasts than more.
This product is injected 200 ~ 1600mg/kg / day no female reproductive capacity of rats, rats differentiation and reproductive capacity development impact.  Injection of rabbits 400 ~ 1600mg/kg / day, a total of 5 in the 800mg/kg / day treatment group and above, the observed nephrotoxicity of cefazolin than weak, but slightly Cefalotin. In mice, rats, guinea pigs and rabbits almost no antigenicity.  And cefmetazole, cefazolin, penicillin G, ampicillin no immunological cross-between, but also no positive Coombs's reaction.

Cefminox disabled or on vinyl cephalosporin antibiotic allergic patients.
?Notes?
Product can be caused by shock, diagnosis should be carefully before use, if the use of skin test should be carried out. Shock first-aid ready to do a good job, to observe the post-administration.
? on the β-lactam antibiotic used with caution in patients with a history of allergy.
? I-or two-parent, brother have bronchial asthma, skin rash, urticaria, such as those used with caution allergy.
? serious caution in patients with renal dysfunction.
? elderly patients should be medication use in elderly patients.
? renal dysfunction adjustable doses.
? lack of oral feeding in patients with non-oral nutrition in patients with maintenance of body status in patients with non-performing [the possibility of lack of symptoms of vitamin K] be used with caution.
? alcohol may cause facial flushing, palpitations, dizziness, headache, nausea, etc., so drug use during and after treatment to avoid alcohol for at least 1 week.
?Pregnant women and lactating women use?
Animal reproductive test Cefminox sodium does not appear to have any reproductive or embryos, but in pregnant women have not carried out any tests, medication safety during pregnancy has not been established, so only when necessary in order to use this drug for pregnant women. Breast-feeding women the drug should be used with caution.
