Aminopenicillins - Study guides, Class notes & Summaries

Antacids MOA - Neutralize gastric acid to bring the pH above 3 and inactivate pepsin • which antacids have the highest absolute neutrophil count (ANC)? - sodium bicarbonate and calcium carbonate • When aminopenicillins are combined with beta-lactamase inhibitors - their spectrum in broadened • beta-lactamase inhibitors that can be combined with aminopenicillins - clavulanate, sulbactam, & tazobactam • Penicillinase-resistant penicillins drugs - Nafcillin - Oxacillin - Cloxacil...

Bacterostatic - CORRECT ANSWER-kills the bacteria bacteriocidal - CORRECT ANSWER-kills the bacteria and stops the growth or spread of the infection Bacteriostatic drugs - CORRECT ANSWER-clindamycin macrolides sulfonamides tetracyclines Bactericidal drugs - CORRECT ANSWER-ahminoglycosides beta-lactums fluroquinolones Metronidazole Streptogramins vancomycin anti-microbial resistance - CORRECT ANSWER-1.) not knowing if the pt had recent use of antibiotics 2.) provider overuse of b...

Penicillin G *** - ANSWER - First PCN given PO and IM - PO only about 1/3 of dose is absorbed - IM and IV are most effective (to get therapeutic serum level) (IM is painful) - primarily bactericidal Penicillin V *** - ANSWER - next type produced - 2/3 absorbed by GI tract, less patent than PCN G - It is effective against mild - moderate infections, including anthrax PCNS (structure) - ANSWER - beta-lactam antibiotics. - beta-lactam structure interferes with bacterial cell wall synth...
