Abstract
A high content of 2-(4-isobutylphenyl)propionic acid is achieved in a pharmaceutical composition by solidifying molten 2-(4-isobutylphenyl)propionic acid to provide a unit dose composition. The composition may be prepared by heating the 2-(4-isobutylphenyl)-propionic acid until molten, optionally mixing with pharmaceutically acceptable excipients, forming into a unit dosage presentation and allowing the composition to solidify. Preferably the composition contains greater than 80% ibuprofen or S(+)-ibuprofen and is filled into a hard gelatin capsule.
