Product Overview:
cefradine (cefradine) is a semi-synthetic cephalosporin antibiotic successfully researched by Squibb Pharmaceutical Company in 1972, belonging to the first generation of cephalosporin, and entered the pharmaceutical market in the 1970s. It is stable to stomach acid and its antibacterial action is similar to cephalexin when administered orally and cephalothiophene when administered by injection. It has a killing effect on most gram-positive and negative bacteria, and has a good antibacterial effect on staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogenes, Streptococcus pneumoniae and Streptococcus virescens which do not produce penicillinase and penicillinase, but has a poor activity on Escherichia coli, Proteus and Klebsiella, and has a certain effect on Neisseria gonorrhoea. It is also active against gonococcus zymogenes, but is less active against Haemophilus influenzae

Pharmacological action of Cefradine.
Cephalosporin is the first generation of cephalosporin, and its antibacterial action is characterized by: (1) the antibacterial action against gram-positive bacteria including penicillin-sensitive and drug-resistant Staphylococcus aureus (except methicillin-resistant staphylococcus aureus) is stronger than the second and third generation cephalosporin; The effect on gram-negative bacteria is not as good as the second generation of cephalosporins, let alone the third generation of cephalosporins. (2) The β-lactamase produced against gram-negative bacillus was unstable, but the β-lactamase produced against Staphylococcus aureus was more stable than the second and third generation cephalosporins.
