일반 설명Triprolidine hydrochloride,(E)-2-[3-(1-pyrrolidinyl)-1-p-tolylpropenyl]pyridine monohydrochloridemonohydrate (Actidil), is a white crystalline powder with a slight, but unpleasant, odor. It is soluble inwater and in alcohol, and its solutions are alkaline to litmus.The antihistaminic activity is confined mainly to the geometricisomer in which the pyrrolidinomethyl group is transto the 2-pyridyl group. Pharmacological studies confirm thehigh activity of triprolidine and the superiority of (E) overcorresponding (Z) isomers as H1-antihistamines. At guineapig ileum sites, the affinity of triprolidine for H-receptorswas more than 1,000 times the affinity of its (Z) diasteromer.The relative potency of triprolidine is of the same orderas that of dexchlorpheniramine. The peak effect occursabout 3.5 hours after oral administration, and the duration ofeffect is about 12 hours.
