Suvorexant (MK-4305) is a dual orexin receptor antagonist currently under clinical investigation as a novel therapy for insomnia. Suvorexant is not currently approved for commercial use, but it has completed three Phase III trials. The recent FDA review showed that Suvorexant (MK-4305) is associated with increased somnolence the next day and users of higher doses had an increased rate of suicidal ideation. Suvorexant works by turning off wakefulness rather than by inducing sleep.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.
