A process for treating the blood-brain barrier by the systemic administration of ibuprofen (p-isobutylhydratropic acid) or a salt or ester thereof. Dosage forms are also disclosed.
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.
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.
