Antibacterial drugs Flashcards
Drugs that slow or retard the multiplication of bacteria
Bacteriostatic
Drugs that kill bacteria.
Bactericidal
Allergy to drugs in the same or related group
Cross-sensitivity
Drugs effective against both gram negative (-), and gram positive (+) bacteria.
Broad Spectrum
Nonpathogenic microorganisms within or on the body.
Normal flora
An overgrowth of bacteria or fungal microorganisms not affected by the antibiotic being used for treatment.
Superinfection
The effectiveness of individual antibiotics depends on these factors
____________
____________
____________
(a) Location of the infection
(b) Ability of the antibiotic to reach the site of infection.
(c) Ability of the bacteria to resist or inactivate the antibiotic.
Primarily bacteriostatic caused by sulfonamide antagonism to paraaminobenzoic acid. Once the bacteria multiplication is slowed the body’ immune system is able to rid the bacteria.
- PENICILLINS
- CEPHALOSPORINES
- TETRACYCLINES
- SULFONAMIDES
SULFONAMIDES
Often used to control urinary tract infections caused by E coli, Staphylococcus aureus, including Methicilin-resistant Staphylococcus aureus, and Klebsiella Enterobacter. Silver sulfadiazine is topical and used to treat burns.
- PENICILLINS
- CEPHALOSPORINES
- TETRACYCLINES
- SULFONAMIDES

no
Examples of what class?
(a) Silver Sulfadiazine: Silvadene (topical)
(b) Trimethoprim/sulfamethoxazole: Bactrim
SULFONAMIDE

Penicillin
Action… what class?
Affect the bacterial cell wall, making it defective and unstable. This action is similar to the action of PCN

CEPHALOSPORINES
Use of what class?
Infections caused by streptococci, staphylococci, citrobacter, gonococci, Shigella, and clostridia.

CEPHALOSPORINES
What is the contraindication for CEPHALOSPORINES
Allergy to Cephalosporin or Penicillin (there is a 1% cross-reactivity rate of
individuals that are allergic to penicillins)
Examples of CEPHALOSPORINES
Cephalexin
or drugs that start with (cef) ir (ceph)
Action of what class?
Inhibit bacterial protein synthesis, which is a process necessary for reproduction
