Chiou and Reigelman first defined solid dispersion as “dispersion of one or more active ingredients in an inert carrier or matrix (hydrophilic) at solid state prepared by fusion, solvent or melting solvent method” [4,5,6], or solid dispersion defined as “a dispersion that include the formation of eutectic mixtures of …
WebClassification of solid dispersions The drug can be dispersed molecularly, in amorphous particles (clusters) or in crystalline particles by melting or solvent method. Therefore, based on their molecular arrangement, different types of solid dispersions (SDs) can be distinguished. They are described in Table 1.4 WebFigure 11.2. 1: Attractive and Repulsive Dipole–Dipole Interactions. (a and b) Molecular orientations in which the positive end of one dipole (δ +) is near the negative end of another (δ −) (and vice versa) produce attractive interactions. (c and d) Molecular orientations that juxtapose the positive or negative ends of the dipoles on ...
