The rate of dissolution for a specific drug is determined by its release kinetics and diffusion coefficient. This Demonstration considers three drugs in everyday use, modeled by a tablet dissolving in a beaker of water. This provides an indication of the pharmacological response to a drug in systemic circulation.
