Gel Dosage Form
Definition 1
A semi-solid composed of a solid, three dimensional, cross linked matrix of polymers within a liquid, yielding a jelly-like material unable to flow at steady state. (NCI Thesaurus)
Definition 2
A semisolid (1) dosage form that contains a gelling agent to provide stiffness to a solution or a colloidal dispersion (2). A gel may contain suspended particles. Note 1: A semisolid is not pourable; it does not flow or conform to its container at room temperature. It does not flow at low shear stress and generally exhibits plastic flow behavior. Note 2: A colloidal dispersion is a system in which particles of colloidal dimension (i.e., typically between 1 nm and 1 micrometer) are distributed uniformly throughout a liquid.
