Mechanism of Action
Cephalexin, also known as Keflex, is an antibiotic medication that belongs to the class of drugs called cephalosporins. It works by inhibiting the synthesis of the bacterial cell wall.
Specifically, cephalexin interferes with the action of enzymes called penicillin-binding proteins (PBPs), which are involved in the cross-linking of peptide chains during bacterial cell wall synthesis. By inhibiting PBPs, cephalexin disrupts the formation of the bacterial cell wall, leading to cell lysis and bacterial death.
Cephalexin is effective against a wide range of bacteria, including both Gram-positive and Gram-negative organisms. It has been found to be particularly effective against streptococcal and staphylococcal bacteria.
The bactericidal action of cephalexin occurs during active bacterial growth. It is important to complete the full course of treatment to ensure eradication of the bacterial infection and prevent the development of antibiotic resistance.
It is worth noting that cephalexin is not effective against infections caused by viruses or fungi. It is specifically designed to target and eliminate bacterial infections.
Overall, the mechanism of action of cephalexin provides an effective means of treating bacterial infections by specifically targeting the bacterial cell wall synthesis process, leading to bacterial death and clearance of the infection.
Indications for Use
Cephalexin is indicated for the treatment of a variety of bacterial infections caused by susceptible microorganisms.
