Abstract
A method of preparing a powder composition comprising disodium salt, of 1,3-bis- (2-carboxychromon-5-yloxy) propan-2-ol, in which a sample of the disodium salt of 1,3-bis (2-carboxychromon-5-yloxy) propan-2-ol having a mass median diameter greater than 4 microns is subjected to direct grinding and/or classification of particles or a solution thereof is appropriately crystallized to give the disodium salt of 1,3-bis (2-carboxychromon-5-yloxy) propan-2-ol having a mass median diameter of 2 to 4 microns, preferably 2.5 to 3.5 microns, and said product is mixed with a vehicle solid powder acceptable to the lungs and having a particle size within the range of 30 to 150 microns.
