Pharmaceutical composition in the form of a colloidal suspension of nanocapsules which comprises an oily phase consisting essentially of an oil containing, in solution, a surface-active agent and, in suspension, nanocapsules having a diameter of less than 500 nanometers, including an aqueous phase consisting essentially of a solution or a suspension of a substance of therapeutic activity, a surface-active agent and optionally ethanol, as well as a process for the preparation of this composition. The walls of the said nanocapsules are formed of a poly(alkyl 2-cyanoacrylate) the alkyl radical of which includes from 1 to 6 carbon atoms. This composition is advantageously suitable for the oral administration of polypeptides and polysaccharides. |
