How Cephalexin Works

The mechanism of action of cephalexin is rooted in its ability to disrupt bacterial cell wall synthesis. This ultimately leads to cell death and the resolution of infection.

• Target Action: Inhibits synthesis of the bacterial cell wall.
• Efficiency: Cephalexin is particularly effective against Gram-positive bacteria and some Gram-negative bacteria.
• Dosage and Administration: The dosage and length of treatment depend on the type and severity of the infection.
