1 of 10

beta-lactam ring structure

inhibiting bacterial cell wall,-->beta lactmase (penicillin, cephalosporins, carbapenems)

2 of 10

4 types of penicillins

basic penicillin, board spectrum penicillin, pencillinase- resistant penicillin, Extended spectrum penicillin

3 of 10

basic penicillin, gram? explamples

gram+(staphylococcal infections),penicillinase sensitive, penicillinG +penicillin V potassium

4 of 10

board spectrum penicillin (aminopencillin)

gram+/-- (e-coli, haemophuilus influenza), peniillinase sensitive, e.g. amoxicillin, amoxicillin-clavulanate, ampicillin, ampicillin-sulbactam)

5 of 10

penicillinase- resistant penicillin( antistaphylococcal penicillin)

(treat penicillinase-producing staphylococcus. aureus)Gram+/-weak , e.g nafcillin, oxacillin sodium, cloxcillin

6 of 10

extended-spectrum penicillin (antipseudomonal penicillin)

board- spectrum penicillin , gram--/+, penicillinase sensitive, e.g. geocillin, tazocin, timentin

7 of 10

broad spectrum antibiotic

penicillinase sensitive penicillin + beta- lactamase inhibitor,( augmentin, unasyn, tazocin, timentin), funcution fro protect function of the antibiotic

8 of 10

penicillin nursing process

monitor the allergy response, ( after first and scond doses, Xcombine with aminoglycosides with penicillin G, BLeeding , dilute the antibiotic for iv use

9 of 10

cephalosporins

beta-lactam structure-->interfere bacteria cell synthesis,osmolarity inside the cell. bactericidal and bacteriostatic effect
