A process for producing a rapidly solubilizing ibuprofen granulate, the process comprising providing a mixture comprising solid ibuprofen and at least 0.8 mole per mole ibuprofen of one or more basic compounds, which basic compounds comprise from 0.5 to 1.2 mole per mole ibuprofen, but not more, of a base selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate, sodium glycinate, potassium glycinate, tribasic sodium and potassium phosphates and mixtures of said bases, and reacting the ibuprofen and said one or more basic compounds in the presence of not more free water than the quantity exceeding the amount of water required for forming solid hydrates in said granulate by more than 1 mole per mole of ibuprofen. The obtainable granulate and the pharmaceutical compositions and dosage forms that may be produced therefrom are distinguished by their high solubility and rapid disintegration and dissolution in aqueous media, by their good flow properties and compressibility, by rapidly achieving onset of analgesic effect, etc.
