Biphasic dosage forms, such as suspensions and emulsions, are widely used in pharmaceuticals and various industries. These formulations consist of two immiscible phases, typically a liquid and a solid or liquid and liquid, that are dispersed within each other. Suspensions are solid particles dispersed in a liquid medium, while emulsions are liquid droplets dispersed in another liquid medium. Understanding the definition, advantages, disadvantages, classification, formulation, stability, and evaluation of biphasic dosage forms is crucial for their proper development and use.
