The present invention provides a method for preparing a suspension of a
pharmaceutically active compound, the solubility of which is greater in a
water miscible first organic solvent than in a second solvent which is
aqueous, The process includes the steps of: (i) dissolving a first
quantity of the pharmaceutically active compound in the water miscible
first organic solvent to form a first solution; (ii) mixing the first
solution with the second solvent to precipitate the pharmaceutically
active compound; and (iii) seeding the first solution or the second
solvent or the presuspension.
