In modulated drug delivery systems, the drug molecules are released or controlled by a range of chemical, biological, physiochemical, physical, or electrical processes. Using a different technique, the same properties can be used to visualise the induced distribution of drug molecules.Pharmaceutics refers to the full process of transforming a novel chemical into a recognisable drug that is safe and effective at treating or preventing disease. For this challenging technique, a wide range of scientific, medical, legal, commercial, and regulatory competence is required.
