Definition: A suspension is a biphasic liquid dosage form containing finely divided insoluble solid particles dispersed uniformly in a liquid medium. The solids are maintained in suspension by employing suitable suspending agents. Suspensions are used for oral, topical, ophthalmic, and parenteral delivery of drugs. Characteristics of Suspensions 1. Heterogeneous System: Composed of two phases—dispersed phase […]
Suspensions can be classified based on various criteria, including the nature of the dispersed phase, the dispersion medium, and the intended use. Here are some common classifications of suspensions: 1. Based on Particle Size Coarse Suspensions: These suspensions contain relatively large particles that are visible to the naked eye. They may settle quickly and often […]
Biphasic liquids refer to a system consisting of two immiscible liquid phases, typically one liquid dispersed in the form of droplets within the other. In such systems, the two liquids do not dissolve or mix uniformly but instead form distinct phases with separate physical and chemical properties.Various types of systems categorize these, including liquid-liquid biphasic […]
