Virkningen afhænger hovedsageligt af hhv. forholdet mellem den maksimale koncentration i serum (Cmax) og den minimale hæmmende koncentration (MIC) af ciprofloxacin for et bakterielt patogen og af forholdet mellem henholdsvis arealet under kurven (AUC) og MIC.
Efficacy mainly depends on the relation between the maximum concentration in serum (Cmax) and the minimum inhibitory concentration (MIC) of ciprofloxacin for a bacterial pathogen and the relation between the area under the curve (AUC) and the MIC.
