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. Glucophage: La metformine réduit la production hépatique de glucose en inhibant le complexe I mitochondrial, ce qui élève le rapport AMP/ATP cellulaire et active l'AMP-kinase.
