The invention is directed to a pre-metered dry powder inhaler provided with a dry powder dose of tiotropium and excipient(s) loaded into a container comprising a dry, high barrier seal, which prevents ingress of moisture so that the fine particle structure of the powder dose is preserved. The dry powder dose has been formed by either volumetric or electric field dose forming methods. The invention is also directed to a dry powder dose of tiotropium loaded into a container as described above. The dry powder inhaler and the dry powder dose of the invention is intended for use in the treatment of asthma and other respiratory disorders.
La présente invention concerne une poudre sèche prédosée à inhaler comprenant une dose de poudre sèche de tiotropium et un ou de plusieurs excipients chargés dans une enveloppe qui comprend un joint sec à haute étanchéité empêchant la pénétration d'humidité qui risquerait de compromettre la structure en fines particules de la dose de poudre. Cette dose a été formée par des techniques soit volumétriques, soit à champ électrique. L'invention concerne également une dose de poudre sèche de tiotropium chargée dans une enveloppe comme décrit ci-dessus. La poudre sèche à inhaler et la dose de poudre sèche sont destinées au traitement de l'asthme et autres troubles respiratoires.
