Phexin BD 375 mg (Cefalexin)
Phexin BD 375 mg contains cefalexin (also spelled cephalexin), a first-generation cephalosporin antibiotic that is widely used for respiratory infections, urinary tract infections, and skin & soft-tissue infections. Cefalexin works by interrupting bacterial cell wall synthesis, leading to bacterial death and clinical improvement.
The **375 mg BD (twice daily)** formulation provides convenient dosing with effective antibacterial coverage for mild to moderate infections.
