Beta Lactam Others Flashcards
Clavulanic Acid + Amoxicillin
Beta lactam inhibitors
Augmentin
Clavulanate K + Ticarcillin
Beta lactam inhibitors
Timentin
Sulbactam Pivoxil + Ampicillin
Beta lactam inhibitors
Unasyn
Tazobactam + Piperacillin
Beta lactam inhibitors
Tazocin
beta-lactamase producing Gramnegative organisms, which were resistant to broad spectrum and extended spectrum penicillins
CARBAPENEMS
P. aeruginosa –except
Ertapenem
Febrile neutropenic patients
imipenem, meropenem, doripenem +/-aminoglycoside
inactivated by dehydropeptidases in renal tubules resulting in low urinary concentrations
Imipenem
penetrates body tissues and fluids well including the CSF
•binds to penicillin binding proteins
Imipenem
Imipenem indications
Urinary tract infection, lower respiratory tract infection, intraabdominaland gynecologic; skin, soft tissue, bone and joint infections
not degraded by dehydropeptidase, thus no cilastatinis needed. •Excessive levels in kidney failure can cause seizures with imipenembut not with
Meropenem
Ertapenem
longest half life, once a day dosing ( 1 gram IV)
•Irritating IM so may give 1% lidocaine
•Less active than the other carbapenems against pseudomonas and acinetobacter
•Not degraded by dyhydropepetidases •Insufficiently active against P. aeruginosa
Similar to imipenem •Sligthly greater activity against gram negative aerobes and slightly less activity against gram positive •Not degraded by dihydropeptidases
Doripenem
MOA –inhibits cell wall synthesis-binds firmly to D-Ala-D-Ala terminus of nascent peptidoglycan pentapeptide-inhibits transglycosylate,preventing further elongation of peptidoglycan and x-linking
Vancomycin
Vancomycin resistance
D-Ala-D-Ala binding site of the peptidoglycan building block
