The invention relates to lifes necessities and in particular those relating to health, more particularly a method for dissolving and improving the intestinal absorption of active ingredients which are poorly-water-soluble or water-insoluble or which cannot be turned into salts in gastric juice, containing one or more active ingredients dispersed in a polyoxyethylene 32 fatty acid ester then hot spraying said dispersion onto a granular excipient in a fluid bed. The powder mixture thus formed is distributed in pharmaceutical compositions after optional dilution in a pharmaceutically-acceptable non-toxic inert excipient. The above is of use in the production of pharmaceutical compositions containing one or more pharmaceutically-acceptable non-toxic inert excipients.
