Mechanism and action
Augmentin: Amoxicillin hemmt die bakterielle Zellwandsynthese durch Bindung an Penicillin-bindende Proteine (PBP), wird aber von Betalaktamasen einiger resistenter Bakterien hydrolysiert. Allegra: Fexofenadin blockiert selektiv die peripheren H1-Histaminrezeptoren und antagonisiert die Wirkungen von Histamin auf Vasodilatation, Kapillarpermeabilität, sensorische Nervenendigungen und glatte Muskulatur.
