This document provides an introduction to dosage form design. It discusses the aims of the course, which are to explain pharmaceutical processing, drug formulation, and biopharmaceutics. It also discusses why a dosage form is needed for a drug and lists some key terms related to dosage form design. The document notes that three main factors contribute to designing an effective dosage form: dosage form related factors, drug related factors, and physiological factors. It provides examples of common dosage forms that will be considered, including solid, liquid, gas delivery, semisolid, transdermal, sustained release, and sterile products.
