Suvotol
Suvotol Uses, Dosage, Side Effects, Food Interaction and all others data.
Suvotol is a highly selective antagonist for orexin receptors OX1R and OX2R. The mechanism by which Suvotol exerts its therapeutic efect 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.

Uses
Suvotol is used for the treatment of insomnia, characterized by difculties with sleep onset and/or sleep maintenance.
Suvotol is also used to associated treatment for these conditions: Insomnia
How Suvotol works
Suvotol is a dual antagonist of orexin receptors OX1R and OX2R. It exerts its pharmacological effect by inhibiting binding of neuropeptides orexin A and B, also known as hypocretin 1 and 2, that are produced by neurons in the lateral hypothalamus. These neurons control the wake-promoting centers of the brain and are active during wakefulness, especially during motor activities, and stop firing during sleep. By inhibiting the reinforcement of arousal systems, suvorexant use causes a decrease in arousal and wakefulness, rather than having a direct sleep-promoting effect.
Dosage
Suvotol dosage
Recommended dose is 10 mg, no more than once per night taken before 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, not to exceed 20 mg once daily. Lowest dose effective should be used for the patient. Time to effect may be delayed if taken with or soon after a meal.
Side Effects
Common side effects are Sleepiness during the day, Not thinking clearly, Act strangely, confused, or upset, Sleep-walking
Toxicity
Dose-related somnolence and CNS depression are the most common adverse effects associated with the use of suvorexant. It has also been shown to impair driving skills and may increase the risk of falling asleep while driving. Next-day impairments are found to be highest if suvorexant is taken with less than a full night of sleep remaining, with higher doses, or if co-administered with other CNS depressants or CYP3A inhibitors. Complex behaviours such as sleep driving, preparing and eating food, and making phone calls have been reported in association with the use of hypnotics such as suvorexant. A dose-dependant increase in suicidal ideation has been observed, especially in patients with a previous diagnosis of depression. Sleep paralysis, hypnagogic/hypnopompic hallucinations including vivid and disturbing perceptions, and mild cataplexy have also been reported. There are no adequate studies in pregnant women to ensure its safety during pregnancy or breast feeding.
Precaution
Daytime somnolence: Risk of impaired alertness and motor coordination, including impaired driving; risk increases with dose; caution patients taking 20 mg against next-day driving and other activities requiring complete mental alertness.
Need to evaluate for co-morbid diagnoses: Reevaluate if insomnia persists after 7 to 10 days of treatment.
Interaction
CNS-Active Drugs: An additive effect on psychomotor performance was observed when a single dose of 40 mg of Suvotol was co-administered with a single dose of 0.7 g/kg alcohol. Suvotol does not afect alcohol concentrations and alcohol does not afect Suvotol concentrations.
effect s of Other Drugs on Suvotol: Strong (e.g., ketoconazole or itraconazole) and moderate (e.g., diltiazem) CYP3A inhibitors signifcantly increased Suvotol exposure. Strong CYP3A inducers (e.g., rifampin) substantially decreases Suvotol exposure.
effect s of Suvotol on Other Drugs: Suvotol is unlikely to cause clinically signifcant inhibition of human CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19 or CYP2D6. Chronic administration of Suvotol is unlikely to induce the metabolism of drugs metabolized by major CYP isoforms.
Food Interaction
- Avoid grapefruit products.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of suvorexant.
Use in combination may result in additive central nervous system depression and In addition, alcohol may increase the risk of cognitive and complex behavioral changes associated with the use of hypnotics including suvorexant, such as amnesia, anxiety, hallucinations, sleep-driving, and other neuropsychiatric symptoms. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. According to the product labeling, administration of suvorexant with a high-fat meal resulted in no meaningful change in peak plasma concentration (Cmax) or systemic exposure (AUC), but a delay in Tmax of approximately 1.5 hours. Patients should be advised not to use suvorexant if they had alcohol that evening or before bed. Grapefruit juice should preferably be avoided; otherwise, the recommended dose of suvorexant is 5 mg when used with grapefruit juice and should not exceed 10 mg. Suvotol may be taken with or without food; however, for faster sleep onset, suvorexant should not be administered with or soon after a meal.
ADJUST DOSE: Grapefruit juice may significantly increase the plasma concentrations of suvorexant.
ADJUST DOSING INTERVAL: Administration with or soon after a meal may delay the gastrointestinal absorption of suvorexant.
MANAGEMENT: Concomitant use of suvorexant with alcohol should be avoided.

Moderate: aripiprazole, zolpidem, lorazepam, duloxetine, clonazepam, lamotrigine, pregabalin, desvenlafaxine, ramelteon, quetiapineUnknown: amphetamine / dextroamphetamine, sucralfate, loratadine, ubiquinone, acetaminophen, cyanocobalamin, cholecalciferol, lisdexamfetamine, bupropion, ondansetron
Suvotol Disease Interaction
Major: depression, severe renal impairment, impaired respiratory function, narcolepsyModerate: glaucoma, liver disease
Volume of Distribution
Mean volume of distribution is approximately 49 litres.
Elimination Route
Peak concentrations occur at a median Tmax of 2 hours under fasted conditions. Ingestion of suvorexant with a high-fat meal has no effect on AUC or Cmax, but may delay Tmax by approximately 1.5 hours. Mean absolute bioavailability of 10 mg is 82%.
Half Life
Mean half life is approximately 12 hours.
Elimination Route
Approximately 66% is eliminated in feces and 23% is eliminated in urine.

Pregnancy Category C. There is no adequate and well-controlled studies in pregnant women. Suvotol should be used during pregnancy only if the potential beneft justifes the potential risk to the fetus.
