ABSTRACT:
This invention relates to a novel process for solubilizing the hydrophobic organic compounds--and namely the pharmaceutical active ingredients--in an aqueous phase.
This process is defined in that the hydrophobic compound is prior dissolved in one or several polymers of high molecular weight, then adding to this solution an aqueous medium the pH of which is fixed.
The aqueous solutions thus resulting are useful for preparing medicines for parenteral, digestive, mucous or transcutaneous administration.
