Title (EN) COMPOSITION COMPRISING AT LEAST ONE DRY POWDER OBTAINED BY SPRAY DRYING TO INCREASE THE STABILITY OF THE FORMULATION
(FR) COMPOSITION COMPRENANT AU MOINS UNE POUDRE SÈCHE OBTENUE PAR SÉCHAGE PAR PULVÉRISATION POUR AUGMENTER LA STABILITÉ DE LA FORMULATION
Abstract:
(EN) The present invention relates to inhalation formulations of drugs in the form of dry powder for inhalation administration deliverable as such with an inhaler and provided with high deliverability, respirability and stability. In particular, the invention relates to a pharmaceutical composition for inhalation use in powder form comprising a first powder comprising at least a powder (a1) comprising an active agent or a pharmaceutically acceptable salt thereof, in an amount greater than 1% by weight of the powder, leucine in an amount from 5 to 70% by weight of said powder, a sugar in an amount from 20 to 90%> by weight of the powder; and a second powder comprising a mixture of a first lactose which has an X50 from 35 to 75 μm, with a second lactose which has an X50 from 1.5 to 10 μm, the content of the first and second lactose in the mixture are respectively from 85% to 96% and from 4% to 15%. The ratio by weight between the first powder and the second powder is from 1/5 to 1/100, and the composition has a fine particle fraction (FPF) greater than 60% and a delivered fraction (DF) greater than 85%.
(FR) La présente invention concerne des formulations pour inhalation de médicaments sous forme de poudre sèche pour administration par inhalation pouvant être administrées telles quelles avec un inhalateur et dotées d'excellentes caractéristiques d'aptitude à l'administration, de respirabilité et de stabilité. En particulier, l'invention concerne une composition pharmaceutique pour une utilisation par inhalation sous forme de poudre comprenant une première poudre comprenant au moins une poudre (a1) comprenant un agent actif ou un sel pharmaceutiquement acceptable de celui-ci, en quantité supérieure à 1 % en poids de la poudre, de la leucine, en quantité de 5 à 70 % en poids de ladite poudre, un sucre en quantité de 20 à 90 % > en poids de la poudre ; et une seconde poudre comprenant un mélange d'un premier lactose, qui présente une X50 de 35 à 75 μm, avec un second lactose, qui présente une X50 de 1,5 à 10 μm, la teneur en premier et en second lactose dans le mélange étant respectivement de 85 % à 96 % et de 4 % à 15 %. Le rapport en poids de la première poudre à la seconde poudre est de 1/5 à 1/100, et la composition a une fraction de particules fines (FPF) supérieure à 60 % et une fraction distribuée (DF) supérieure à 85 %.
