Abstract

For the Contracting States : BE, CH, DE, GB, IT, LI, NL, SE 1. Process for coating at least one solid medicament active principle, slightly soluble in water and presented in a finely divided form, characterized in that the said active principle and an aqueous dispersion of one or more pharmaceutically acceptable solid hdyrophobic agents are mixed together under agitation, the said hydrophobic agent is made to flocculate by a physical or chemical means or a combination of these means, the active principle so coated is separated and dried. For the Contracting State : AT 1. Process for coating at least one solid medicament active principle, slightly soluble in water and presented in a finely divided form, characterized in that the said active principle and an aqueous dispersion of one or more pharmaceutically acceptable solid hdyrophobic agents are mixed together under agitation, the said hydrophobic agent is made to flocculate by a physical or chemical means or a combination of these means, the active principle so coated is separated and dried.
