Embodiment 1

[0264] grass extract

[0265] Grass pollen extract according to Ipsen and L Prepared as described in wensten (1983) Jour. Allergy. Clin. Immunol. 72:2, pp. 150-159. Briefly, grass pollen was extracted in ammonium bicarbonate at 5°C for 20 hours. Particulate matter was removed by centrifugation and the supernatant was dialyzed 3 times against water, freeze-dried and stored under refrigerated conditions until reconstitution.

[0266] Solid dosage form:

[0267] Manufacturing process:

[0268] 1. MQ water is added to a beaker with a magnetic stirrer,

[0269] 2. Mannitol and Sorbitol, if desired, are added and dissolved under stirring,

[0270] 3. Maltodextrin and PEG, if required, are added and dissolved under stirring,

[0271] 4. Allergen extracts, if desired, are added,

[0272] 5. If the allergen is present, the pH is adjusted to pH=7-8, and adjusted with hydrochloric acid (2N) or sodium hydroxide (2N),

[0273] 6. Under ambient temperature conditions, 250 μl of the...

Abstract

The present invention provides a non-compressed fast-dispersing solid dosage form suitable for oromucosal administration of a pharmaceutically active substance comprising (a) a first matrix forming agent in the form of maltodextrin having a dextrose equivalent (DE) of between 1 and 20,(b) a second matrix forming agent in the form of sorbitol, and (c) the active substance.

Description

technical field [0001] The present invention relates to non-compressible fast-dispersing solid dosage forms suitable for the administration of pharmaceutically active substances and for the manufacture of compressed fast-dispersing tablets. Background of the invention [0002] Allergies are a major health problem in countries adapted to a Western lifestyle. Furthermore, the prevalence of allergic diseases is increasing in these countries. Although allergies are generally not considered life-threatening diseases, asthma causes a significant number of deaths each year. The abnormal prevalence of approximately 30% among adolescents results in significant losses in quality of life, working time and money, and secures a classified place among the major health problems in the Western world. [0003] Allergies are complex diseases. Many factors contribute to hypersensitivity events. Among these are individual susceptibilities determined by the interaction of several genes which...
