- infective endocarditis |
- GU/GI procedures |

|
|
General AE of ABX
Vomiting |
Severe watery diarrhea |
Abdominal cramps |
Allergic rxn |
Antibiotic Spectra
Narrow Spectrum |
Active against single or limited group of microorganisms |
Extended Spectrum |
Effective against G+ and some G- |
Broad Spectrum |
Effective against both G+ and G- |
Static Vs. Cidal
Bacteriostatics
inhibit growth without causing death
Sulfonamides (DNA synthesis), Chloramphenicol (transcription and translation)
Relies on INTACT immune system to clear nongrowing/viable bacteria |
Bactericidal
Kill bacteria
PCN (cell wall inhibitor)
Can be given to patients with COMPROMISED immunity |
