Eksperimentel: Liquid formulation of an extract of a 6 grass pollen mixture
Sublingual application containing allergen extracts of 6 grass pollen species (Holcus lanatus, Dactylus glomerata, Lolium perenne, Phleum pratense, Poa pratensis, Festuca pratensis) pollen allergen extract. The study solution was applied sublingually, kept under the tongue for 3 minutes, and swallowed thereafter. Initial treatment was applied on the first day of treatment with a starting dose of 25% of the maintenance dose. Increasing doses of 50% were applied with the second and 100% with the third dose to give the maximum (=maintenance) dose. This was followed by a daily patient selfadministered treatment with the maintenance dose. |
