Phexin BD 750 mg (Cefalexin)
Phexin BD 750 mg contains cefalexin (also spelled cephalexin), a first-generation cephalosporin antibiotic widely used for respiratory infections, urinary tract infections (UTIs), skin and soft-tissue infections, and certain ENT conditions. It works by disrupting bacterial cell wall synthesis, causing bacterial death and promoting rapid symptom relief.
The 750 mg BD formulation (twice daily) offers convenient dosing for moderate infections, improving patient adherence and therapeutic outcomes.
Product introduction
Cefalexin is a beta-lactam antibiotic effective against many Gram-positive organisms and selected Gram-negative bacteria. Phexin BD 750 mg provides a higher-strength oral tablet suitable for infections requiring stronger systemic coverage. It is commonly prescribed for outpatient treatment where hospitalization is not needed.
Because of its broad spectrum and tolerability, cefalexin is a preferred choice for skin infections, throat infections, and lower urinary infections. It is available by prescription and should only be used under medical guidance.
