Pneumonia Flashcards
Inhibitors of cell wall synthesis
Beta lactam antibiotics and vancomycin
Beta lactam antibiotics are
Penicillins
Cephalosporins
Carbapenems
Monobactams
Inhibitors of protein synthesis
Inhibit 50s ribosomal subunit ( macrolides, linezolid )
Inhibit 30s ribosomal subunit
( Aminoglycosides , tetracyclins )
Inhibitors of 50s ribosomal subunit
Macrolides
Linezolid
Inhibitors of 30s ribosomal subunit
Aminoglycosides
Tetracyclins
Inhibitors of nucleic acid synthesis
Quinolones
Inhibit transpeptidation reaction essential for bacterial cell wall synthesis
Penicillin and Cephalosporins
Sensitive penicillins are inactivated by …..
Beta lactamase enzymes
Drugs that are effective against streptococcus pneumoniae and hemophilus influenza
Amoxicillin
Amoxicillin with clavulanate ( B- lactamase inhibitors)
Drug that is effective against staph.aureus infection
Flucloxacillin
Drug that effective against pseudomonas infection
Ticarcillin
Adverse effects of penicillin
Hypersensitivity reaction (anaphylactic shock)
Neurotoxicity
Superinfection
First generation of Cephalosporins is
Cephalexin
Second generation is
Cefuroxime
Third generation is
Cefotaxime
Adverse effects of Cephalosporins
Hypersensitivity reaction
Super infection
Nephrotoxicity
Example of monobactams is
Aztreonam
Drugs that are resistant to beta lactamases
Monobactams (aztreonam)
Drugs that are active against gram negative bacteria like aminoglycosides
Monobactams (aztreonam)
Drugs that also inhibit cell wall synthesis
Monobactams (Aztreonam)
Examples of carbapenems
Imipenem
Meropenem
Drugs that have a broad spectrum of activity ( against gram positive and negative bacteria)
Carbapenems ( imipenem and meropenem)
Drugs that are inactivated by a renal proteolytic enzyme and must therefore be combined with cilastatin which inhibits the enzyme
Carbapenems (imipenem and meropenem)
Drug which is only active against gram positive bacteria
Vancomycin
Used in if the patient is allergic to penicillin and in MRSA cases
Vancomycin
Adverse effects of vancomycin
Ototoxicity
Red neck syndrome
Drug that bind reversibly to the 50s ribosomal subunit and inhibit bacterial protein synthesis
Macrolides
Drug that effective against gram +ve bacteria
Macrolides
Examples of macrolides
Erythromycin
Azithromycin
Clarithromycin
Used in allergy of penicillin
Macrolides (erythromycin, azithromycin and clarithromycin)
Drugs that bind to 30S subunit so inhibit protein synthesis
Aminoglycosides and tetracycline
Drugs that are effective against gram -ve bacteria ( pseudomonas infections )
Aminoglycosides
Example of aminoglycosides
Streptomycin
Neomycin
Amikacin
Gentamicin
Adverse effects of aminoglycosides
Nephrotoxicity
(Reversible renal tubular damage)
Ototoxicity
Neuromuscular blockade
Drugs that are effective against most gram positive and most gram negative bacteria
Tetracyclins
Example of tetracycline
Cholrtetracycline
Oxytetracycline
Doxycycline
Adverse effects of tetracyclins
Nausea
Vomiting
Diarrhea
Superinfection
Yellow discoloration of teeth and deformity of bone
Hepatotoxic
Nephrotoxic
Drug that is binds to 50s subunit to inhibit protein synthesis (bactericidal)
Linezolid
Drug that is active against positive cocci especially vancomycin and methicillin resistant staph.aureus
Linezolid
Adverse effects of linezolid
Thrombocytopenia and GI disturbance.
Drugs that inhibit DNA gyrase
Fluoroquinolones
Drug that is effective against gram -ve bacteria
Fluoroquinolones
Examples of fluoroquinolones
Moxifloxacin
Levofloxacin
Adverse effects of fluoroquinolones
Nausea, vomiting and diarrhea
Arthropathy
