In Vitro	Triprolidine (maturing human dendritic cells) can antagonist histamine H1 and decreases the expression of CD45[1].
In Vivo	Triprolidine (292.81-1467.20 μg/kg; i.p.; Male Sprague-Dawley rat) produces a dose-dependent effect of spinal motor and sensory block in rats[2]. Animal Model: Male Sprague-Dawley rat (300-350 g)[2] Dosage: 292.81, 488.02, 733.60, 1098.83 and 1467.20 μg/kg Administration: Intrathecal injection Result: Elicited spinal block in a dose-dependent.
