How to use

In Vitro:

Eplivanserin hemifumarate (SR 46349B) shows weak inhibition on other 5-HT kinases, with IC50s of 0.12 μM (Pig cortex 5-HT1C), 14 μM (Rat hippocampus 5-HT1A), and 16 μM (Rat stnatum 5-HT1B, Ox caudate nucleus 5-HT1D). Eplivanserin also has inhibitory effects on rat cortex adrenergic α1 and α2, rat whole brain histammine H1, Na+ channel, and rat striatum dopamine D1 and D2, with IC50s of 3.4 μM, 1.0 μM, 5.0 μM, 39 μM, 9 μM and 28 μM, respectively.

In Vivo:

Eplivanserin hemifumarate (SR 46349B) inhibits 5-HT2 receptor binding of [3H]ketanserin with an ED50 of 0.087 mg/kg after i.p. injection, and 0.097 mg/kg after p.o administration in mice. SR 46349B (0.25-1 mg/kg; i.p.) blocks Cocaine-evoked hyperactivity following repeated Cocaine treatment in rats.
