titleOfInvention |
Colloidal suspension of submicronic particles for carrying active principles and their mode of preparation |
abstract |
The present invention relates to a suspension of biocompatible particles for carrying the active ingredient. The carrier particles are based on double block hydrophilic neutral polyamino acids / hydrophobic neutral polyamino acid copolymers. The hydrophilic neutral polyamino acid / hydrophobic neutral polyamino acid particles can bind one or more active ingredients in an undissolved colloidal suspension, and in particular release them in a prolonged and / or delayed delivery mode in vivo. . The present invention also provides a powdered solid inducing carrier particles; And the preparation of said solids and said suspension of the active ingredient based on hydrophilic neutral polyamino acids / hydrophobic neutral polyamino acids. The carrier particles spontaneously form stable aqueous suspensions in the absence of surfactants or organic solvents. The invention also relates to a carrier particle in dry form, a process for their preparation and a pharmaceutical composition (dry form or suspension) comprising said carrier particle to which the active ingredient is bound. |
