Abstract: The use of S(−)sodium 2-(4-isobutylphenyl)-propionate (the sodium salt of S(+)-ibuprofen) in pharmaceutical compositions for the treatment of inflammation, pain and pyrexia is described. Preferred compositions comprise S(−)sodium 2-(4-isobutylphenyl)-propionate dihydrate. Processes to prepare S(−)sodium 2-(4-isobutylphenyl)propionate and its use in a process to prepare S(+) 2-(4-isobutylphenyl)propionic acid of high enantiomeric purity are also described.
