Pharmacological particulars
ATC Vet Code: QJ01DB01
Pharmacodynamic properties
Cefalexin is a semi-synthetic bactericidal antibiotic belonging to the cefalosporin group which acts by interference with bacterial cell wall formation.
Cefalexin is resistant to the action of staphylococcal penicillinase and is therefore
active against the strains of Staphylococcus aureus that are insensitive to penicillin
(or related antibiotics such as ampicillin or amoxycillin) because of production of
Cefalexin is also active against the majority of ampicillin-resistant E.coli.
Pharmacokinetic Properties
Cefalexin is rapidly absorbed after injection. Peak blood concentrations are generally achieved within one hour of administration. Cefalexin is excreted in the urine in high concentration.
