All Drugs Flashcards
This drug inhibits the 50 s ribosomal subunit to block peptide bond formation, is used for bone/joint infections and anaerobes above the diaphragm (aspiration pneumonia), has no gram negative activity, and has side effects that include pseudomembranous colitis, blood disorders and cellulitis.
Clindamycin
These drugs inhibit the PBP transpeptidase enzyme to decrease bacterial cell wall synthesis, are bactericidal but extremely sensitive to B-lactamases. They are used for infection with strep, pneumococci, enterococci, and syphilis. A main side effect is hypersensitivity.
Penicillin G (IV, IM) Penicillin VK (PO)
This drug is a penicillin-ase resistant drug and is the drug of choice for infections with non-MRSA staphylococcus.
Nafcillin
This broad spectrum drug is an amino-penicillin that is well absorbed orally, inhibits the excretion of methotrexate, and is almost always combined with clavulanic acid to inhibit B-lactamases (“Augmentin”).
Amoxicillin
This broad spectrum amino-penicillin is the drug of choice for prophylaxis of infective endocarditis, is inactivated by hydrocortisone, and causes interactions with oral contraceptives. Renal excretion of this drug is slowed down by probenecid.
Ampicillin
This drug is an anti-pseudomonal penicillin and is the broadest spectrum penicillin available. It is active against Pseudomonas, Klebsiella, and other G - microbes.
Piperacillin
These drugs are 1st generation cephalosporins that are penicillin-ase resistant, used for infections with P. mirabalis, E. Coli, and Klebsiella pneumoniae. These drugs are usually used before surgery, but are not the drug of first choice for any infection.
Cefazolin
Cephalexin
These drugs are 2nd generation cephalosporins that can be used to treat H. influenzae and some anaerobes and are B-lactamase resistant. They are also used to treat Enterobacter, Neisseria gonorrhoeae, and the microbes treated by the first generation.
Cefoxitin
Cefaclor
Cefuroxime
This 2nd generation cephalosporin is able to cross the BBB
Cefuroxime
These two 3rd generation cephalosporins have good activity against Gram - rods, are used for Gram - sepsis, meningitis, and anaerobes, and are good for gonococcus infection. They can cross the BBB.
Cefotaxime
Ceftriaxone
This 3rd generation cephalosporin is active against pseudomonas
Ceftazidime
This 3rd generation cephalosporin is used for upper respiratory infections
Cefdinir
This 4th generation cephalosporin is active against Pseudomonas but has poor anaerobic coverage.
Cefepime
This 5th generation cephalosporin is active against MRSA and is used for complicated skin infections and community acquired pneumonia.
Cetaroline
This non-B-lactam drug is used topically, blocks peptidoglycan synthesis, and is active against G- and G+ microbes. Side effects include nephrotoxicity and ototoxicity.
Bacitracin
Side effects of Cephalosporins include…
increased toxicity of aminoglycosides
pseudomembranous colitis from C. difficile superinfection
This non-B-lactam drug binds cell wall precursors and only has G+ activity. It is best used for multi-drug resistant G+ infections like MRSA, VRE, and C. difficile. Side effects include nephrotoxicity, ototoxicity, and Red Man syndrome.
Vancomycin
This non-B-lactam drug forms ion channels in the cell membrane, is used for MRSA and VRE (but not for pneumonia), and has side effects that include Rhabdomyolysis
Daptomycin
This category of antimicrobials inhibits the 30s ribosomal subunit to block initiation, cause misreading, and cause premature termination. Side effects include nephrotoxicity, ototoxicity, neuromuscular paralysis and teratogenicity.
Aminoglycosides
This drug is an aminoglycoside that is most commonly prescribed.
Gentamycin
This aminoglycoside is used topically.
Neomycin
This aminoglycoside has the broadest spectrum.
Amikacin
This category of drugs inhibits the 30s ribosomal subunit to prevent the attachment of amino-acyl tRNAs. They can be used to treat acne vulgaris. They are the drugs of choice for Rickettsia, mycoplasma, chlamydia, cholera, lyme disease and plague. Adverse effects include photosensitivity, discoloration of teeth, disulfuram-like reactions, C. difficile superinfection, interactions with dairy, iron, and antacids, and teratogenicity.
Tetracyclines
This specific tetracycline is active against MRSA, multi-drug resistant Streptococcus penumoniae, VRE, and some anaerobes.
Tigecycline.
This category of drugs inhibit the 50s ribosomal subunit to prevent the translocation step of protein synthesis. They are broad spectrum and the safest of all antimicrobials. They are generally used for upper respiratory infections and community acquired pneumonia.
Macrolides (Azithro-, Clarithro-, and Erythro-mycin)
This Macrolide is preferred for Chlamydia and URIs (H. influenzae, moraxella, and mycobacterium)
Azithromycin
This Macrolide is used for Neisseria gonorrhoeae, Chlamydia, mycoplasma, Legionella, and non-MRSA staph.
Erythromycin
This drug inhibits the 50s ribosomal subunit (peptidly transferase enzyme), can cross the BBB, is used for life threatening infections with H. influenzae, meningitis and rickettsia in children and can cause various anemias and Gray Baby Syndrome.
Chlorempenicol
This drug inhibits the 50s ribosomal subunit, is used for MRSA, VRE, and healthcare-acquired pneumonia. Side effects include bone marrow suppression and seratonin syndrome.
Linezolid
This category of drugs inhibit the 50s ribosomal subunit and are used for life-threatening bacteremias caused by VRE as well as Vancomycin-resistant staph aureus skin infections. Side effects include myalgia/arthalgia and hyperbilirubinemia.
Streptogramins
This drug inhibits tRNA synthetase and is used topically for impetigo. It is also used for MRSA and methicillin-resistant Strep pyogenes infections.
Mupirocin
This category of drugs blocks both topo II and topo IV enzymes to prevent DNA synthesis. They distribute well though all tissues, especially the lungs. Divalent cations (like those found in dairy and antacids) interfere with the oral absorption of these drugs. They most commonly cause GI upset buy are contraindicated in pregnant women and patients that take NSAIDs, can cause photosensitivity, exacerbate myasthenia gravis, and cause tendinitis or tendon rupture
Fluroquinolones
This quinolone is the drug of choice for prophylaxis and treatment of anthrax and is the best quinolone for pseudomonas. It is also used for uncomplicated UTIs and traveler’s diarrhea.
Ciprofloxacin
This 3rd generation quinolone is the only one that can cross the BBB.
Oxfloxacin
This 4th generation quinolone is the best respiratory quinolone. It can cause prolonged QT syndrome.
Moxifloxacin
