Identification
- Summary
Cefapirin is a first generation cephalosporin indicated in the treatment of susceptible bacterial infections.
- Generic Name
- Cefapirin
- DrugBank Accession Number
- DB01139
- Background
Cefapirin (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. Cefapirin is partly plasma-bound and is effective against gram-negative and gram-positive organisms.

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

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Cefapirin may decrease the excretion rate of Abacavir which could result in a higher serum level. Abciximab The therapeutic efficacy of Abciximab can be decreased when used in combination with Cefapirin. Aceclofenac The risk or severity of nephrotoxicity can be increased when Cefapirin is combined with Aceclofenac. Acemetacin The risk or severity of nephrotoxicity can be increased when Cefapirin is combined with Acemetacin. Acenocoumarol The risk or severity of bleeding can be increased when Cefapirin is combined with Acenocoumarol. - Food Interactions
