Pharmadynamics describes the complex interrelation established between the animicrobial pharmacocynetics profile and the in effectiveness of the antimicrobial agent may be predicted using three pharmacodynamics parameters: inhibitory maximal concentration/minimal concentration (Cmax/CMI), area under the curve of plasmatic/time concentration against CMI (ABC/CMI)l lenght of dose interval where concentration pass the CMI (T> CMI). The specific type of the antimicrobial agent determines that the parameter is better po predict its effectiveness. At present time, the use of antimicrobial agent remains being empirically frustrating mainly with respecto to inter-dosis interval and the lenght time of antimicrobial therapy. Given that th new agents for multiresistant pathogens may to go pass decadesto be available in therapeutical arrays, the knowledge and application of pharmacocynetics and pharmacodynamics principles is a better alternative to optimize the use of ancient and new anatimicrobial agents allowint to identify drugs exposition parameters closely related to ability to destroy the microorganisms and to suppress the appearance of resistance in subpopulations of organisms.
