Cefa-Lak (INN, also spelled cephapirin), commonly marketed under the trade name Cefadyl, is a first-generation cephalosporin antibiotic that is available in injectable formulations. Production for use in humans has been discontinued in the United States. Cefa-Lak is partly plasma-bound and is effective against gram-negative and gram-positive organisms.

Cephapirin is a first-generation cephalosporin that has a wide spectrum of activity against gram-positive and gram-negative organisms. Cephapirin is more resistant to beta-lactamases than are the penicillins and so is effective against staphylococci, with the exception of methicillin-resistant staphylococci.

How Cefa-Lak works

The bactericidal activity of cephapirin results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs).

Toxicity

Rats exposed via the oral route to cephapirin displayed low acute toxicity (LD₅₀ = 14000 mg/kg). The most common adverse reactions are hypersensitivity reactions and alterations to liver function. Evidence of white blood cell disorders and anaemia were noted in some subjects.
