Description

Cephalexin 500 mg Cap 100 is an oral antibiotic belonging to the first-generation cephalosporin class. It is widely used for treating bacterial infections caused by susceptible organisms. Each capsule contains 500 mg of cephalexin, making it effective in combating infections of the respiratory tract, skin, urinary tract, and bone.

The mechanism of action of cephalexin involves inhibiting bacterial cell wall synthesis. It binds to penicillin-binding proteins, disrupting the cross-linking of peptidoglycans, which are essential for bacterial cell wall integrity. Cephalexin is primarily active against gram-positive organisms such as Streptococcus species and Staphylococcus aureus, as well as some gram-negative bacteria.

Cephalexin capsules are usually taken orally, every 6 to 12 hours, depending on the infection and the physician's instructions. The medication is absorbed rapidly in the gastrointestinal tract and reaches peak plasma concentrations within an hour. Common side effects include gastrointestinal upset, nausea, diarrhea, and rash.
