COLLOIDAL SUSPENSION OF SUBMICRONIC PARTICLES OF VECTORIZATION OF HYDROPHILIC ACTIVE PRINCIPLES AND THEIR PREPARATION MODE. |
| abstract |
The invention relates to a suspension of biocompatible particles of vectorization (PV) of active ingredients (PA). Said PVs are based on a double block copolymer of hydrophilic neutral polyamino acid (polyAANI) / hydrophobic neutral polyamino acid (polyAANO). Said polyAANl / polyAANO particles are capable of associating in colloidal suspension to the undissolved state, at least one AP and releasing this, notably in vivo, in a prolonged and / or delayed manner. The invention also comprises a powdery solid from which the PVs are emitted as well as the preparation of this solid and of this suspension of PV based on polyAANl / polyAANO. These new PVs are formed spontaneously and without the help of organic surfactants or stable solvents, aqueous suspensions. The invention also relates to PV in dry form, its method of preparation, as well as pharmaceutical compositions (dry form or suspension) comprising these PVs associated with an active ingredient. |
