    Study Notes

    Amoxicillin/Clavulanate

    • A beta-lactam antibiotic, commonly used for community-acquired pneumonia and sinusitis, with a beta-lactamase inhibitor to enhance efficacy against beta-lactamase-producing bacteria
    • Mechanism of action: inhibits bacterial cell wall synthesis and beta-lactamase enzymes

    Doxycycline

    • A tetracycline antibiotic
    • Mechanism of action: inhibits protein synthesis at the 30S ribosomal subunit
    • Adverse effect: photosensitivity, should be avoided in children under 8 due to potential for tooth discoloration

    Azithromycin

    • A macrolide antibiotic
    • Mechanism of action: binds to the 50S ribosomal subunit, blocking protein synthesis
    • Adverse effect: QT prolongation

    Levofloxacin

    • A fluoroquinolone antibiotic
    • Mechanism of action: inhibits DNA gyrase
    • Adverse effect: tendon rupture, especially in elderly patients, black box warning for optic neuritis

    Cefdinir

    • A third-generation cephalosporin in the beta-lactam antibiotic class
    • Mechanism of action: inhibits bacterial cell wall synthesis
    • Primary indication: skin infections, community-acquired pneumonia
    • Adverse effect: diarrhea

    Ceftriaxone

    • A third-generation cephalosporin
    • Mechanism of action: inhibits bacterial cell wall synthesis
    • Primary indication: severe bacterial infections, such as meningitis, in hospital settings
    • Adverse effect: GI upset, potential for C.difficile, hyperuricemia

    Rifampin

    • Used in the treatment of tuberculosis
    • Mechanism of action: inhibits RNA polymerase
    • Adverse effect: orange-colored bodily fluids

    Isoniazid

    • Used in the treatment of tuberculosis
    • Mechanism of action: inhibits synthesis of mycolic acids (the building blocks of the mycobacterial cell wall)

    Amoxicillin/Clavulanate

    • Combines amoxicillin, a beta-lactam antibiotic, with clavulanate, which inhibits beta-lactamase enzymes

    Azithromycin

    • Belongs to the macrolide class of antibiotics
    • Binds to the 50S ribosomal subunit, blocking protein synthesis
    • Commonly used for respiratory infections and can be used for some sexually transmitted infections
    • Can cause QT prolongation

    Levofloxacin

    • Belongs to the fluoroquinolone class of antibiotics
    • Inhibits DNA gyrase, an enzyme crucial for bacterial DNA replication
    • Has a black box warning for tendon rupture, especially in older adults
    • Commonly used for bacterial respiratory infections and urinary tract infections

    Cefdinir

    • A third-generation cephalosporin, which is a class of beta-lactam antibiotics
    • Inhibits cell wall synthesis
    • Primarily used to treat skin infections and community-acquired pneumonia
    • Commonly causes diarrhea

    Ceftriaxone

    • Belongs to the third-generation cephalosporin class of antibiotics
    • Known for causing hyperuricemia
    • Inhibits cell wall synthesis
    • Used in hospital settings for severe bacterial infections, such as meningitis

    Rifampin

    • Primarily used in the treatment of tuberculosis
    • Has a unique side effect: It can cause orange-colored bodily fluids

    Isoniazid

    • Inhibits synthesis of mycolic acids, which are essential for cell wall synthesis in mycobacteria
    • Used in combination therapy for treating tuberculosis

    Ethambutol

    • Inhibits the synthesis of arabinogalactan, an essential component of the mycobacterial cell wall
    • Used in combination therapy for treating tuberculosis

    Pyrazinamide

    • Mechanism of action is not fully understood
    • It is known to be an effective anti-tuberculosis drug
    • Used in combination therapy for treating tuberculosis
