Cellulitis is an infection that affects the deeper layers of the skin and subcutaneous tissue, while impetigo is a highly contagious infection that causes itchy, crusted sores. Cephalexin works by targeting and eliminating the bacteria responsible for these infections. Patients with skin infections may experience symptoms such as redness, swelling, pain, and oozing of the affected area. It is essential to take cephalexin as directed and follow proper wound care practices to promote healing and prevent complications.
Mechanism of Action of Cephalexin
Cephalexin, a widely prescribed antibiotic, works by inhibiting the growth of bacteria in the body. It belongs to a class of drugs known as cephalosporins, which are structurally similar to penicillin. Cephalexin exerts its therapeutic effects by disrupting the formation of the bacterial cell wall, leading to the destruction of the bacterial cells. This mechanism of action is crucial in treating various bacterial infections, as it prevents the bacteria from reproducing and spreading throughout the body.
By targeting the bacterial cell wall, cephalexin specifically acts on Gram-positive bacteria, such as Staphylococcus aureus and Streptococcus pneumoniae. These bacteria have a thick peptidoglycan layer in their cell walls, which cephalexin can effectively disrupt. However, cephalexin is generally less effective against Gram-negative bacteria, due to the presence of an outer membrane that acts as a physical barrier. This limitation highlights the importance of proper diagnosis and understanding the specific bacterial strain causing the infection, to ensure the optimal effectiveness of cephalexin.
