Abstract

Procedure for coating fine particle medicines, with a particle diameter of up to 1 mm, by fluidizing the product in a fluidized bed and spraying the fluidized bed with a solution of the coating substance, characterized in that the coating substance is dissolved in a mixture of solvents of at least two solvents, which have different boiling points, whereby the coating substance dissolves better in the solvent with a lower boiling point than in the solvent with a higher boiling point.
