Cephalexin

Description:
Cephalexin is a first-generation cephalosporin antibiotic, primarily used to treat bacterial infections. It is effective against a variety of gram-positive bacteria and some gram-negative bacteria, making it useful for treating conditions such as respiratory tract infections, skin infections, and urinary tract infections. The chemical formula of cephalexin is C16H17N3O4S, and it features a beta-lactam ring, which is essential for its antibacterial activity. Cephalexin is typically administered orally and is well-absorbed in the gastrointestinal tract. It is known for its relatively low toxicity and side effects, although some patients may experience allergic reactions or gastrointestinal disturbances. The drug is generally contraindicated in individuals with a history of hypersensitivity to cephalosporins or penicillins. Its pharmacokinetics involve renal excretion, necessitating dosage adjustments in patients with impaired kidney function. Overall, cephalexin remains a widely used antibiotic due to its efficacy and safety profile in treating various bacterial infections.
