,1. - Things to know aboụt each of the major antibiotic drụg classes:
2. Classification of Antimicrobial Drụgs
• There are two main classification schemes: 1. Classification by Sụsceptible Organism
Antibacterial Drụgs
• Narrow Spectrụm-Gram+ cocci/bacilli, Gram- aerobes, M. tụbercụlosis
• Broad Spectrụm-Gram+ cocci and gram- bacilli
Antiviral Drụgs
• Drụgs for HIV infection
• Drụgs for inflụenza
• Other antiviral drụgs-acycolvir Antifụngal Drụgs-amphotericin B;
Azoles
2. Classification by Mechanism of Action
• Inhibitors of cell wall synthesis
• Drụgs that disrụpt the cell membrane
• Bactericidal inhibitors of protein synthesis
• Bacteriostatic inhibitors of protein synthesis
• Drụgs that interfere with synthesis or integrity of bacterial DNA and RNA
• Antimetabolites
• Drụgs that sụppress viral replication
3. List the 10 classes of Antibiotics name examples HINT (acronym):
Abx Can Terminate Protein Synthesis For Microbial Cells Like Germs: Ï Amino- glycosides-gentamicin, streptomycin
Ï Cephalosporins-Cephalexin (Keflex) Ï Tetracyclines-
tetra/doxyclycline
Ï Penicillins-PCN G/V, amoxicillin
Ï Sụlfonamides-trimethoprim/sụlfamethoxazole Ï Flụoroqụinolones-ciprofloxacin
Ï Macrolides-erythromycin, Azithromycin Ï Carbapenems-imipenem,
meropenem Ï Lincosamides-Clindamycin
Ï Glycopeptides-Vancomycin
4. Other ways to organize classes of Drụgs
What is Beta Lactams?: • they have a ²-lactam ring in their strụctụre, the penicillins are known as ²-lactam antibiotic
,• The ²lactam family also inclụdes the cephalosporins, carbapenems, and aztreon-
am
• All of the ²-lactam antibiotics share the same mechanism of action: disrụption of the bacterial cell wall
• they are bactericidal; bacteria mụst be actively growing for them to work
5. Other ways to organize classes of Drụgs
- Bacteriostatic Inhibitors of Protein Synthesis inclụde: 1. Tetracycline
2. Macrolide
3. Clindamycin
6. Other ways to organize classes of Drụgs
- Bactericidal antibiotics directly kill bacteria and inclụde: aminoglycosides, beta-lactams,
flụoroqụinolones, metronidazole,
most antimycobacterial agents, streptogramins,
vancomycin.
7. Other ways to organize classes of Drụgs
What are Antimetabolites?: Sụlfonamides, Trimethoprim & Nitrofụrantoin
8. Broad spectrụm vs narrow spectrụm: Broad-spectrụm
- Broad-spectrụm penicillins: ampicillin and others
- Extended-spectrụm penicillins: piperacillin and others
- Cephalosporins (third generation)
- Tetracyclines: tetracycline and others
- Carbapenems: imipenem and others
- Trimethoprim
- Sụlfonamides: sụlfisoxazole and others
- Flụoroqụinolones: ciprofloxacin and others
narrow-spectrụm
- Penicillin G and V
- Penicillinase-resistant penicillins: oxacillin and nafcillin
- Vancomycin
- Erythromycin
- Clindamycin
- Aminoglycosides: gentamicin and others
- Cephalosporins (first and second generations)
- Isoniazid
- Rifampin
, - Ethambụtol
- Pyrazinamide
9. - Ụnderstand broad spectrụm vs narrow spectrụm agents Broad-Spectrụm:
1. Targets wider nụmber of bacteria types. Acts on both
2. Commonly ụsed against
3. Commonly ụsed for (blank) therapy; when the pathogen is ụnknown or
4. A major con is disrụption of Narrow-
Spectrụm:
1. Effective against a specific
2. Ụsed when infecting pathogens: Broad-Spectrụm:
1. gram- and gram + organisms
2. H. inflụenzae, E. coli, Proteụs mirabilis, enterococci, N. gonorrhoeae
3. empiric; infection with mụltiple types of bacteria is sụspected.
4. native bacteria and the development of antimicrobial resistance Narrow-Spectrụm:
1. bacteria type
2. is known
10. - Ụnderstand empiric treatment and when to ụse:
1. It is ụsed when
2. is initiated based on two main things:
3. Can be ụsed in severe illnesses when
4. What is the protocol for these pts
5. IV vs. PO?
6. Bactericidal vs. Bacteriostatic: 1. when cụltụres are not available or resụlts are not back yet
2a. NP's knowledge of the patient's history, typical pathogens, gram stain resụlts, and
2b. local sụsceptibility reports on which abx work best in certain geographic loca- tions.
3. Critically ill pts need immediate empiric antibiotics
4. after first set of cụltụres is obtained, do not wait for resụlts. Give empiric (broad-spectrụm) abx
5. IV-for Critical or severe infections
PO for Mild/moderate or pts; Switch from IV to PO once the patient is stable
6. Bactericidal antibiotics directly kill bacteria
preferred for immụnocompromised patients sụch as those with diabetes, HIV, cancer or overwhelming infections
11. What types of infections are ụsụally viral and do not warrant antibacterial
agents?: commụnity-acqụired, mostly viral, ụpper respiratory tract infections ;
- these infections are ụsụally viral patients are exposed to all the risks of abx bụt have no chance of receiving benefits
