Drug kinetics graph
Web10 nov 2024 · Most controlled drug delivery systems—including injectable FDA formulations—exhibit release kinetics characterized by an initial period of rapid release followed by first-order release in which the rate of drug release is proportional to the amount remaining in the device (Fig. 1 B) [[33], [34], [35]]. Webtionships between the drug kinetic profile and the physiological process which drive the drug absorption, distribution and elimination. For ex-ample, compartmental models allow to define easily the clearance which is dependent on the drug elimination process, or the volume of distri-bution which depends on the drug distribution in the tissues.
