Package for multiple dose inhalators having optimised emptying properties

Abstract

The invention relates to a package for pharmaceutical compositions, mixtures or formulations for use in a powder inhaler.

1 . A package for use in a powder inhaler, the package being optimised in its shape and in the fill level to a pharmaceutical composition, mixture, or formulation and adapted to be opened in such a way that the delivery of the pharmaceutical composition, mixture, or formulation is optimised, wherein the package is a capsule or a blister, a blister disc, a blister coil, or a blister strip with one or more wells, and wherein, per capsule or well, the sum of the inflow surfaces is equal to the sum of the outflow surface or surfaces per well or capsule.  
   
   
       2 . The package according to  claim 1 , wherein the package is a capsule.  
   
   
       3 . The package according to  claim 2 , wherein the package is a size 2-4 capsule.  
   
   
       4 . The package according to  claim 2 , wherein the package is a size 3 capsule.  
   
   
       5 . The package according to  claim 1 , wherein the well or capsule is teardrop-shaped and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       6 . The package according to  claim 1 , wherein the well or capsule is oval in shape and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       7 . The package according to  claim 1 , wherein the well or capsule is in the form of a figure-of-eight and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       8 . The package according to  claim 1 , wherein the well or capsule has a shape as shown in any one of  FIGS. 1-13 .  
   
   
       9 . The package according to  claim 1 , wherein the well or capsule has an opening pattern as shown in any one of  FIGS. 1-13 .  
   
   
       10 . A powder inhaler comprising a package that is optimised in its shape and in the fill level to a pharmaceutical composition, mixture, or formulation and adapted to be opened in such a way that the delivery of the pharmaceutical composition, mixture, or formulation is optimised, wherein the package is a capsule or a blister, a blister disc, a blister coil, or a blister strip with one or more wells, and wherein, per capsule or well, the sum of the inflow surfaces is equal to the sum of the outflow surface or surfaces per well or capsule.  
   
   
       11 . The powder inhaler according to  claim 10 , wherein the package is a capsule.  
   
   
       12 . The powder inhaler according to  claim 11 , wherein the package is a size 2-4 capsule.  
   
   
       13 . The powder inhaler according to  claim 11 , wherein the package is a size 3 capsule.  
   
   
       14 . The powder inhaler according to  claim 10 , wherein the well or capsule is teardrop-shaped and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       15 . The powder inhaler according to  claim 10 , wherein the well or capsule is oval in shape and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       16 . The powder inhaler according to  claim 10 , wherein the well or capsule is in the form of a figure-of-eight and the inflow surfaces and the outflow surface or surfaces are at the maximum spacing from one another.  
   
   
       17 . The powder inhaler according to  claim 10 , wherein the well or capsule has a shape as shown in any one of  FIGS. 1-13 .  
   
   
       18 . The powder inhaler according to  claim 10 , wherein the well or capsule has an opening pattern as shown in any one of  FIGS. 1-13 .
