Cephalexin capsules play a vital role in modern medicine as a first-generation cephalosporin antibiotic. Effective against a wide range of bacterial infections, cephalexin capsules are commonly prescribed for skin infections, urinary tract infections, respiratory tract infections, and bone infections caused by susceptible gram-positive and some gram-negative bacteria. By inhibiting bacterial cell wall synthesis, cephalexin capsules disrupt bacterial growth, aiding in infection resolution. Their oral administration, favorable safety profile, and affordability make them a preferred choice for outpatient treatment. However, antibiotic resistance poses challenges, necessitating judicious use of cephalexin capsules to preserve their efficacy in combating bacterial infections.
