Sulfonamides (less effective secondary to resistance):
PCN
Staph (Skin, bone, joint)
Penicillinase Resistant Penicillins (PRPs):
Strep and Group A Strep (GAS)
Natural and broad-specturm
Β-Lactamase Inhibiting Compounds (BLIC):
respiratory, S. pneumoniae, GAS
staph and strep (Gr + activity)
Cephalosporins 1st and 4th generations
Cephalsporin 2nd gen
Moderate Gr+ activity
Cephlasporin 3rd
more Gram - coverage than Gram + coverage
Some Staph, indicated for CA-MRSA
Tetracyclines
Staph, poor activity S. pneumonaie
Fluoroquinolones
variable activity against Gram + Strep and Staph; some Gram + bacilli (Gut)
Macrolides
UTI (growing resistance TMP-SMX), less respiratory coverage secondary to
resistance. Special use Pneumocystis carinii
Sulfonamides
Gram – cocci and some Gram –
bacilli (UTI, although growing resistance)
Penicillins Natural
: Gram – bacilli, pseudomonas BLIC: Gram + and
Gram –
Extended spectrum (Ticarcillin, Piperacillin)
aerobic Gr- (GI/GU); not effective against anaerobes
Fluoroquinolones
