Causes of drug resistance People not completing their antibiotics/inappropriate use,
overuse of broad spectrum ABO's
Every ABO class has_____________________ resistance organisms
Vaccination with pneumococcal vaccine has decreased resistance
Inhibits the biosynthesis of peptidogylcan bacterial cell wall, bactericidal:
Pharmacodynamics of penicillin
4 classes of penicillin penicillin, aminopenicillin, penicillinase-resistant-penicillins,
antipsuedomonal penicillins
Penicillin G, Aqueous penicillin G, Procaine Pcn G, Benzathine Pcn G, PCN V Penicillin class,
works on Strep group A&B (Gram+)
Ampicillin, Amoxicillin Aminopenicillins, work better for gram -, also active against gram +
Methicillin, Nafcillin, Oxacillin, Dicloxacillin Penicillinase-resistant-penicillins (2nd generation
pcn)
penicillinase enzyme produced by bacteria that destroy the beta lactam rink of the antibiotic
making penicillin ineffective.
titarcillin Piperacillin Antipseudomonal penicillin's that are combined with calvulanate
, Carbenicillin antipseudomonal penicillin
Bactericidial inhibits bacterial cell wall synthesis (PCN, Cephalosporins)
Diuretics can interact with PCN, hypo/hyperkalemia
Methotrexate interact with PCN, increase Methotrexate level
Oral Contraceptives PCN may reduce efficacy
Probenecid interact with pcn, delay renal elimination, increase blood levels
Tetracyclines Interact with PCN, due to bacteriostatic action of tetracycline
Warfarin Interact with PCN, increase risk of bleedin
Beta Blockers interact with ampicillin, reduces bioavailability
Allopurinol interacts with ampicillin, more likely to develop rash
Cyclosporine interacts with Nafcillin, produces subtherapeutic cyclosporine levels
Colestipol interacts with PCN G by decreasing absorption
Cholestryramine interacts with PCN, by decreasing absorption
