In vitro study | Alvimopan inhibits the loperamide-stimulated [ 35 S]GTPγS binding to membranes containing the cloned human μ-opioid receptor, with an IC 50 of 1.7 nM. |
In vivo study | Alvimopan (0.1-1.0 mg/kg; p.o.) partially antagonizes the slowing of small intestinal transit of 113 Sn-labelled microspheres produced by morphine in rats. Alvimopan (3 mg/kg; p.o.) has no effect on the visceromotor behavioural responses (VMR) induced by noxious colorectal distension (CRD) in conscious rats. |

biological activity | Alvimopan (LY-246736) is an effective and relatively non-selective opioid antagonist with Ki values of 0.77, 4.4 and 40 nM for μ, δ and κ opioid receptors respectively, the selective ratio is more than 100 times higher than that of other amine G protein coupled receptors |
