Antimicrobials Flashcards
Doxycycline
non-renally eliminated tetracycline
Quinolones
ciprofloxacin is renally eliminated but is a non-substrate inhibitor of P450 (caffeine-theophylline)
Clindamycin
non-renally eliminated
Rifampin
inducer of P450, potential for hepatotoxicity
Isoniazid
genetic polymorphism of N-acetyl transferase metabolism, potential for hepatotoxicity
Metronidazole
drug-drug interaction with alcohol due to inhibition of aldehyde metabolism (Antabuse reaction)
Erythromycin-like
drug-drug interactions due to inhibition of P450 (Clar-Ery not Azi)

N-acetylated to a more lipid-soluble metabolite → concern for renal crystalluria
