MOA Warfarin
inhibits the carboxylation step in the synthesis of vitamin k dependent clotting factors II, VII, IX and X
Reversal of anticoag med is vit K and/or FFP
Reversal of heparin
pratomine sulfate
MOA TXA
amino acid (lysine) analog that prevents degradation of clot by preventing formation of plasmin from plasminogen
Botulism MOA
blocks presynaptic release of acetylcholine
Baclofen
Gamma aminobutryic acid (GABA) agonist
effects more centrally. Occurs primarily at spinal cord level to inhibit the transmission of both monosynaptic and polysynaptic reflexes.
Lidocaine
blocks voltage gated sodium channels
MOA Abatacept
MHC receptor antagonist
Adalimumab
TNF a
Infliximab
TNF a
Inhibition of which enzyme results in the pharmacologic antipyretic effect of acetaminophen?
IL1-beta
MOA penicillins
inteferes with bacterial cell wall synthesis disrupts the synthesis of the peptidoglycan layer of bacterial cell walls
MOA cephalosporins
disrupts the synthesis of the peptidoglycan layer of bacterial cell walls
Does so through competitive inhibition on PCB
MOA Fluoroquinolones
blocks DNA replication via inhibition of DNA gyrase
MOA aminoglycosides
-cidal
binding to the 30s ribosome subunit, leading to the misreading of mRNA – results in the synthesis of abnormal peptides that accumulate intracellularly and eventually lead to cell death
gentamycin
Vancomycin
-cidal
inhibitor of cell wall synthesis
Inhibits cell wall synthesis by binding to the D-Ala-D-Ala terminal of the growing peptide chain during cell wall synthesis, resulting in inhibition of the transpeptidase, which prevents further elongation and cross-linking of the peptidoglycan matrix
MOA Rifampin
inhibits bacterial DNA-dependent RNA synthesis by inhibiting bacterial DNA-dependent RNA polymerase
MOA linezolid
binds to the 23S portion of the 50S subunit and acts by preventing the formation of the initiation complex between the the 30S and 50S subunits of the ribosome
Anti 50s ribosome abx
Macrolides Chloramphenicol Lincosamide Linezolid Stretogramins
MOA acetominophen
inhibits prostaglandin E2 production through its effect on interleukin-1 beta.
MOA pregabalin and gabapentin
reduce hyper-excitability of voltage dependent Ca2+ channels in activated neurons.
gabapentin: binds presynaptic calcium channels to inhibit release of neurotransmitters
