THERAPEUTIC AGENT FOR ALLERGIC CONJUNCTIVAL DISEASE

摘要

Novel pharmacological efficacy (pharmaceutical usage) of 9-cyclopentyl-7-ethyl-3-(thiophen-2-yl)-5,6-dihydro-9H-pyrazolo[3,4-c]-1,2,4-triazolo[4,3-a]pyridine and 2-(3-chlorophenoxy)-3-[3-(3-hydroxypyridin-4-yl)propoxy]pyridine. These substituted pyridine derivatives without exception exhibit excellent allergic conjunctival symptom suppressing effects on allergic conjunctival models, so that they are useful as a therapeutic agent for allergic conjunctival diseases, such as allergic conjunctivitis, spring catarrh and atopic keratoconjunctivitis.
