At present, the most prevalent pharmaceutical dosage forms, the oral immediate-release tablets and capsules, are granular solids. The problem of such solids is that their microstructure and properties are not predictable from physical models. As a consequence, product development and manufacture are resource-intensive and time-consuming, and quality control is statistical by testing rather than by design. Furthermore, the range and repeatability of the drug release rate, and the variety of active ingredients that can be processed to a functional product, are limited in such dosage forms. Presented herein, accordingly, is a fibrous dosage form suitable for immediate-release applications prepared by a predictable liquid-based process. The fibrous dosage form includes a drug-containing solid comprising a three dimensional structural network of one or more drug-containing fibers.
