Cephalexin Usage and Synthesis.

Cephalexin is a broad spectrum antibiotic. The mechanism of action in human body is to inhibit the synthesis of cell wall, so that the substances in the cell expand and finally break and dissolve, so as to achieve bactericidal effect. Human cells have no cell wall and are therefore harmless to humans. It is mainly used for gram-positive bacteria and negative bacteria infection, and also has a good bactericidal effect on penicillin-resistant bacteria. The absorption is rapid and complete after entering the body, and the bioavailability is high. Cephalexin is mainly used for respiratory tract infection, urinary tract infection, obstetrics and gynecology infection, skin and soft tissue infection, gonorrhea and so on caused by sensitive bacteria. It is suitable for respiratory tract infection, urinary tract infection and skin soft tissue infection caused by sensitive bacteria. This product is an oral preparation and should not be used for severe infections.
