Abstract: A clear, stable, and palatable liquid ibuprofen composition has ibuprofen, or a pharmaceutically acceptable salt or ester of ibuprofen, in an aqueous medium containing a methylcellulose composition. A process of making such an ibuprofen composition is significantly simpler and less expensive to carry out than prior processes of making liquid ibuprofen compositions. The liquid ibuprofen composition may also contain pharmaceutically acceptable alcohol, dispersing and suspending agents, viscosity increasing agents, flavorings, and preservatives.

Abstract: A novel water soluble alkali metal salt of ibuprofen is prepared by reacting ibuprofen and an alkali metal bicarbonate in a aqueous medium. The salt is useful in treating pain, inflammation, and fever in mammals. It permits the preparation of a number of novel formulations which result in pharmaceutically and commercially acceptable dosage forms.

Abstract: A constant release rate indomethacin formulation in tablet unit dosage form, said tablet comprising an intimate admixture of from 50 to 200 mg of indomethacin, from about 1.7 to 3.7 weight percent of a slow-dissolving, water-insoluble cellulose derivative, from about 1.5 to 5.0 weight percent of a tabletting disintegrant, and from about 40 to 80 weight percent of a pharmaceutically acceptable bulking agent or diluent.
