Curator's Comment: Description was created based on several sources, including http://www.msd-animal-health.co.nz/products/Metricure_/020_Product_Details.aspx | http://pharm-sci.tbzmed.ac.ir/Drug-Information/Integrative%20Medicine%20Professional%20Access/ProfDrugs/Cephapirinpd.html

Cephapirin is a first-generation cephalosporin. Cephapirin has been indicated for the treatment of infections when caused by susceptible strains in respiratory, genitourinary, gastrointestinal, skin and soft tissue, bone and joint infections, septicemia; treatment of susceptible gram-positive bacilli and cocci (never enterococcus); some gram-negative bacilli including E. coli, Proteus, and Klebsiella may be susceptible. Cephapirin is used in veterinary as an intra-uterine antibiotic infusion for the treatment of subacute and chronic endometritis in cows and repeat breeders.

In Vitro Use Guide

All S aureus isolates were susceptible to cephapirin and ceftiofur. Most coagulase-negative staphylococci were susceptible to cephapirin and ceftiofur. For E coli, 50 (51.0%; cephapirin) and 93 (94.95%; ceftiofur) isolates were susceptible to the parent compounds, but 88 (89.8%) were not inhibited at the maximum concentration of desacetylcephapirin. All S dysgalactiae isolates were susceptible to ceftiofur and cephapirin, and consistent MICs were obtained for all compounds. Most S uberis isolates were susceptible to cephapirin and ceftiofur. Of 98 S aureus isolates classified as susceptible to ceftiofur, 51 (52.0%) and 5 (5.1%) were categorized as intermediate or resistant to desfuroylceftiofur, respectively. For 99 coagulase-negative staphylococci classified as susceptible to ceftiofur, 45 (45.5%) and 17 (17.2%) isolates were categorized as intermediate or resistant to desfuroylceftiofur, respectively. For all staphylococci and streptococci, 100% agreement in cross-classified susceptibility outcomes was detected between cephapirin and desacetylcephapirin. No E coli isolates were classified as susceptible to desacetylcephapirin.
