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.
