Compounds antagonistic of the pain enhancing effects of prostaglandins are disclosed. The compounds comprise an optionally-substituted A ring with a —CH(R3)N(R2)B—R1 and —OD groups positioned in a 1,2 relationship to one another on ring carbon atoms. The 3-position ring-atom is not substituted. B is an optionally-substituted pyridyl ring and the group R1 is positioned on B in a 1,3 or 1,4 relationship with the —CH(R3)N(R2)B- linking group. R1, R2 and R3 and D can be a number of different organic or halogen moieties. N-oxides of —NR2 and S-oxides of sulphur containing rings are disclosed as are processes for the preparation of the compounds, intermediates in their preparation, pharmaceutical compositions containing them, and their use as therapeutic agents.
