Description
Cephalexin is an antibiotic from the group of cephalosporin of the 1 generation. This is a beta-lactam antibiotic which has higher resistance as to beta-lactamase than penicillin. Cephalexin can be destructed under the action of chromosomal lactamase which are produced by the gram-negative microorganisms. Due to this reason, to increase a resistance to beta-lactamase, scientists have started to synthesize different derivatives of cephalosporin of 2, 3 and 4 generation.
Despite the fact that Cephalexin belongs to the first generation of cephalosporins, it provides high results in the treatment of the infectious diseases. It provides a bactericidal action as to bacteria.
The mechanism of this action is related to the affections of the cellular wall of bacteria which are at procreation. Then, special enzymes are produced which begin to kill the unprotected microorgansisms.
Cephalexin is the only cephalosporin antibiotic which is completely absorbed from the gastro-intestinal tract and does not cause severe irritation of the mucous membrane of the GIT. So, if you have taken cephalosporin before and had side effects, the antibiotic will be replaced by Cephalexin.
