Laboratorios LETI is the leading Spanish manufacturer in allergen immunotherapy, and aspires to become a world reference manufacturer in this field. LETI already possesses a significant market share in Portugal as well, and is making important contributions to the development of immunotherapy in various markets in Latin America and South Africa. Since 2001, LETI has been present in the German market—the first ranking world market in this speciality—where the widespread acceptance of our products allows us to view the future commercial development of this market with optimism. LETI is the only Spanish company member of the European Allergen Manufacturers Group (EAMG.)

At present, the most important products of the Allergy Unit are the line of depigmented allergenic extracts, Depigoid, launched in 2000, and the TOL line of allergenic extracts for sublingual administration.

Allergic pathology is clearly increasing in the industrialised world, and LETI considers that immunotherapy will have an increasingly important role in the management of such diseases. The laboratory therefore reaffirms its commitment to this activity and maintains an ambitious research and technological investment program to maximise its competitive capacity in this field over the long term.
