摘要

This chapter provides an overview of the factors that are considered in dosage form design, including physicochemical properties of drugs, drug solubility and dissolution, drug bioavailability, membrane permeability, and solid-state characteristics. Commonly performed preformulation studies including dissolution testing, x-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, particle size analysis, and drug degradation testing, are discussed.
