Abstract: The invention disclosed herein is a process for increasing the achievable concentration of a pharmaceutically active ingredient relative to fill composition viscosity for dosage units. The process is particularly useful in the preparation of soft gelatin capsules containing ibuprofen, naproxen, indomethacin, and acetaminophen, as the pharmaceutically active ingredient. As a result of the process, lesser quantities of composition ingredients other than the pharmaceutically active ingredient are needed to accomplish the same therapeutically effective dosage, thereby significantly increasing the concentration of the pharmaceutically active ingredient resulting in either a reduction in overall fill volume and dosage unit size or an increase in concentration of pharmaceutically active ingredient per dosage form.
