-
Beta-lactams
- Penicillin G, Oxacilllin, Ampicillin, Icarcillin, Pipercillin
- works against gram positive bacteria
- mech: inhibits steps in cell wall syn & murcin assembly
-
Penicillian
- gram postive
- strep, C. diptheria, syphilis (spirochete)
-
Ampicillin; Amoxycillian
- gram negative bactera- Enterococcus, E. coli, H. flu, UTI
- inhibits cell wall (peptiodogylcan) syn and murcin assembly
-
Piperacillin/ Tazobactam
- Big gun for:
- -nosocomial gram positive & negative & anaerobes in intra-abdominal inections, pnuemonia, or sepsis
-
Streptomycin;
Aminoglyoside
- Binds 30s subunit:
- - Incorporates aberrant prots
- into cell wall
- - Blocks initiation at fMET
TB and Plaque. Rarely used bc of resistance
toxicity- fluid in ear, leads to vertigo, then ataxia and eventually loss of higherpitched sounds
-
Gentamincin
- Aminoglycoside
- serious gram negative bacteria, nosocomial
- inhibit protein syn by inhibiting translation. binds 30 s subunit
-
Vancomycin
- gram positive bacteria, esp Staph aures- MRSA
- inhibits peptidooglycan syn & assembly
- toxicity- flushing! nephro- & ototoxicity, thrombophelbitis
-
Clindamycin
gram postive and anaerobes. good for above the diaphragm infections. for lung abcesses & infections w. anaerobes
binds 50s subunit, inhibits translation
can cause superinfection w/ c. difficle
-
Azythromycin, Erythromycin, Clarithromycin
- Macrolides
- gram positive bacteria, gram negative bacteria
- use for URI (comm acquired) and pneumonias: Neisseria, Legionella, Mycoplasma
- bingds 50s subunit, inhibits translocation
-
Imipenem, Meropenem
blocks cell wall syn
- Big gun for:
- - Serious nosocomial infection
- - Broad spectrum = gram (+)
- and (-) inclding pseudomonas
- -Drug of choice for enterobacter
- Must be admin w/Cilistatin b/c Imipenem is inactivated
- by dihydropeptidases in children
-
Ceftriaxone
3rd gen cephalosporin
- used for gram negative, penicillin-resistant:
- -N. gonorrhea
- -N. meningitis
- - & for pneumonia
-
Ceftazidine
3rd gen cephalopsorin
gram-negative, esp Pseudomonas
-
Cefeprime
4th gen cephalosporin
- big gun for:
- - MDR organisms
- -B-lactamase resistant
- - gram neg nosocomial infections
-
Ciproflaxcin
- 2nd gen quinolones
- inhibits DNA gyrase
- gram negative esp gasteroenteritis- salmonella, shigella, pseduonomnas
-
Levoflaxcin
- 3rd gen quinolones
- gram positive
- for:
- -serious, comm acquired pneomnia
- -flu, sinisitis, chronic bronchitis
-
Doxycycline
binds 30s subunit
- used for zoonotic infections:
- -Rocky Mt Spotted Fever (Rickettsia), Lyme disease (Borrelia),
- -Urerithis (Chlamydia trachomoatis)
toxicity: turns teeth yellow (binds Ca2+)
-
Linezolid
binds 50 s subunit
VRE resistance gram positive that cause endocartitis, osteomyelitits, bacteremia
can cause reversible bone marrow suppression
-
Daptomycin
disrupts plasma membrane w/o entering cytoplasm
- MDR gram positive:
- VRE and Staph
- For complicated skin and soft tissue infections
-
Telethromycin
binds 2 sites on ribosome & therefore hard to develop resistance
use for: macrolide-resistance strep pneumonaie
inhibits P450
