Abstract[English]
The present invention relates to formulations, devices and delivery of leucine-5-enkephalin (LENK) formulated with N-palmitoyl-N-acetyl-N-monomethyl-N,N-dimethyl-N,N,N-trimethyl-6-O-glycolchitosan (GCPQor Molecular Envelope Technology - MET). In particular, the present invention relates to delivering leucine-5-enkephalin encapsulated in GCPQ. intranasally via a drug or medicine dispersion and delivery system. The dispersion methods employ curved surfaces to impart rotational motions to one or more fluid flows from a pressurized container to create turbulence and improve mixing of medicament with fluid.[French]
La présente invention concerne des formulations, des dispositifs et l'administration de leucine-5-enképhaline (LENK) formulée avec du N-palmitoyl-N-acétyl-N-monométhyl-N,N-diméthyl-N,N,N-triméthyl-6-O-glycolchitosane (GCPQ ou Technologie d'enveloppe moléculaire - MET). En particulier, la présente invention concerne l'administration de leucine-5-enképhaline encapsulée dans du GCPQ par voie intranasale par l'intermédiaire d'un médicament ou d'une dispersion de médicament et d'un système d'administration. Les procédés de dispersion utilisent des surfaces incurvées pour conférer des mouvements de rotation à un ou à plusieurs écoulements de fluide depuis un récipient sous pression pour créer une turbulence et améliorer le mélange d'un médicament avec un fluide.
