Cephalexin 300 mg Tablets for Cat

Cephalexin 300 mg Tablets for Cat

Cephalexin 300 mg Tablets (commonly marketed as Lixen) contain cephalexin monohydrate, a first-generation cephalosporin antibiotic widely used in veterinary medicine. It is prescribed to manage skin, urinary, respiratory, and soft tissue bacterial infections in cats. Cephalexin is bactericidal, meaning it kills bacteria rather than just inhibiting their growth.

The 300 mg strength is typically used for medium to larger cats or when higher dosing is required under veterinary supervision.

How Cephalexin Works

Cephalexin works by:

• Binding to penicillin-binding proteins (PBPs)
  
• Blocking peptidoglycan cross-linking
  
• Disrupting bacterial cell wall formation
  
• Causing bacterial cell rupture and death
  

It is effective against many Gram-positive bacteria and certain Gram-negative organisms commonly responsible for feline infections.
