ALK-B

Alk-Abelló A/s

A Danish pharmaceutical company that makes allergy immunotherapy treatments — tiny under-the-tongue tablets like GRAZAX, sold for grass allergies in Europe and Australia, that retrain the immune system to tolerate allergens rather than just masking symptoms. It began in 1923 in a Copenhagen hospital pharmacy, where a young doctor and the hospital's pharmacist teamed up to make the first allergen extracts. The name blends the Danish initials "ALK" with "Abelló," the surname of the founder of a Spanish allergy firm it acquired in 1992.
