International ClassA61K 009/14Foreign Application Priority Data1990-01-24 GBAbstractPharmaceutical excipients useful in dry powder inhalents comprise particles having a rugosity (measured by air permeametry) of less than 1.75. The use of these carriers increases the amount of drug injested by the patient using a dry powder inhaler. The preferred excipients are crystalline sugars such as lactose which may conveniently be prepared by controlled crystallisation from an aqueous medium.Field of SearchOrganic pressurized fluidPowder or dust containing Particulate form (e.g., powders, granules, beads, microcapsules, and pellets) Containing polysaccharides (e.g., sugars) Mucosal (e.g., nasal, etc.) Mouth Peptide containing (e.g., protein, peptones, fibrinogen, etc.) DOAI Produced by or extracted from animal tissue Insulin or derivative Carbohydrate (i.e., saccharide radical containing) DOAI 9,10-seco- cyclopentanohydrophenanthrene ring system (e.g., vitamin D, etc.) DOAI Nitrogen containing other than solely as a nitrogen in an inorganic ion of an addition salt, a nitro or a nitroso DOAI Cyclopentanohydrophenanthrene ring system DOAI Bicyclo ring system having the hetero ring as one of the cyclos (e.g., chromones, etc.) | |
