ABSTRACT:
Allergens are contained in strictly controlled and reproducible amounts on solid supports to provide a progressive release of the allergen perlingually and sublingually. The compositions are prepared by dissolving an allergen in a polar solvent to obtain a mother solution; preparing dilutions of different predetermined concentrations; fractionating each of the dilutions into sub-dilutions; and impregnating a pharmaceutically acceptable solid support with each sub-dilution, each impregnation step being followed by drying in forced, dried air at a temperature not greater than 30.degree. C.; and applying a protective coating onto the composition.
