Mechanism and action
Doxycycline: La doxycycline se lie de façon réversible à la sous-unité ribosomique 30S des bactéries, empêchant la fixation de l'aminoacyl-ARNt et inhibant la synthèse protéique. Diflucan: Le fluconazole est un antifongique triazolé qui inhibe la lanostérol 14-alpha-déméthylase, enzyme dépendante du cytochrome P450, bloquant la synthèse de l'ergostérol à partir du lanostérol.
