Description

Suvorexant is a selective dual antagonist of orexin receptors OX1R and OX2R. It has been approved for the treatment of insomnia. The mechanism by which suvorexant exerts its therapeutic effect in insomnia is presumed to be through antagonism of orexin receptors. The orexin neuropeptide signaling system is a central promoter of wakefulness. Blocking the binding of wake-promoting neuropeptides orexin A and orexin B to receptors OX1R and OX2R is thought to suppress wake drive.

Sample Use Guides

In Vivo Use Guide

The recommended dose for BELSOMRA (suvorexant) is 10 mg, taken no more than once per night and within 30 minutes of going to bed, with at least 7 hours remaining before the planned time of awakening. If the 10 mg dose is well-tolerated but not effective, the dose can be increased. The maximum recommended dose of BELSOMRA is 20 mg once daily

Route of Administration: Oral

In Vitro Use Guide

Examination of Suvorexant in radioligand binding assays using tissue from transgenic rats expressing the human OX2R found nearly full receptor occupancy (>90%) at plasma exposures of 1.1 μM.
