oxacillin, nafcillin, dicloxacillin (Sk)
- beta lactams
- bactericidal against cell wall
- penicillin binding protein (PBP) forms peptidoglycan cross-links
- beta-lactamases are ineffective against anti-staph penicillins (reason described later)
- bulky R-groups of anti-staphpenicillins (e.g. nafcillin, oxacillin) prevent beta-lactamase binding
- Nafcillin: non-MRSA staph coverage
- oxacillin: non MRSA staph coverage
- Against non-MRSA staphylococci
- good for abscesses (post E&D), and folliculitis
- treat staphylococcal endocarditis caused by MSSA
- treat osteomyelitis (who are we kidding, we are gonna use vancomycin bc it's never MSSA in the bone)
- MRSA produces altered PBPs resistant to beta-lactam antibiotics(e.g. anti-staph penicillins)
- not effective on MRSA
- for cropping errors
