The present invention relates to 3-(heteroaryl-amino)-1,2,3,4-tetrahydro-9H-carbazole derivatives of the formula (I),
wherein R

are as described in the description and their use as prostaglandin receptor modulators, most particularly as prostaglandin D
2
receptor modulators, in the treatment of various prostaglandin-mediated diseases and disorders, to pharmaceutical compositions containing these compounds and to processes for their preparation.
Certain tetrahydrocarbazole-1-acetic acid derivatives are potent and selective antagonists of the prostaglandin D2 receptor, and are therefore useful in the treatment of allergic conditions such as allergic rhinitis.
