The invention relates to benzimidazole acetic acid compounds which
function as antagonists of the Chemoattractant Receptor-homologous
molecule expressed on T-Helper type 2 cells (CRTH2) receptor. The
invention also relates to the use of these compounds to inhibit the
binding of prostaglandin D.sub.2 and its metabolites or certain
thromboxane metabolites to the CRTH2 receptor and to treat disorders
responsive to such inhibition.
