Abstract
The present invention relates to methods for producing a stable amorphous dispersion of a pharmaceutically active substance having poor water solubility by applying low frequency acoustic energy to a mixture comprising the active substance and at least one polymer and heating the mixture until a stable amorphous dispersion is formed. The methods of the invention are an effective means of converting a crystalline API to a substantially amorphous and stable form, i.e., wherein the crystallinity is less than about 5%. The methods of the invention result in more complete amorphization, increased solubility, drug loading and stability as compared typical amorphization or literature methods.
