Hui Te Ning
Hui Te Ning Uses, Dosage, Side Effects, Food Interaction and all others data.
Hui Te Ning, a pyrazolopyrimidine, is a sedative and hypnotic agent structurally unrelated to the benzodiazepines and other sedative-hypnotic agents. It is shown to interact with GABA subtype A complex by binding selectively to benzodiazepine type 1 receptor. It reduces sleep latency without affecting sleep duration.
Hui Te Ning is a nonbenzodiazepine hypnotic from the pyrazolopyrimidine class and is indicated for the short-term treatment of insomnia. While Hui Te Ning is a hypnotic agent with a chemical structure unrelated to benzodiazepines, barbiturates, or other drugs with known hypnotic properties, it interacts with the gamma-aminobutyric acid-benzodiazepine (GABABZ) receptor complex. Subunit modulation of the GABABZ receptor chloride channel macromolecular complex is hypothesized to be responsible for some of the pharmacological properties of benzodiazepines, which include sedative, anxiolytic, muscle relaxant, and anticonvulsive effects in animal models. Hui Te Ning also binds selectively to the CNS GABAA-receptor chloride ionophore complex at benzodiazepine(BZ) omega-1 (BZ1, ο1) receptors.

Uses
Hui Te Ning is used for the short-term treatment of insomnia. Hui Te Ning has been shown to decrease the time to sleep onset for up to 30 days in controlled clinical trials.
Hui Te Ning is also used to associated treatment for these conditions: Insomnia
How Hui Te Ning works
Hui Te Ning exerts its action through subunit modulation of the GABABZ receptor chloride channel macromolecular complex. Hui Te Ning also binds selectively to the brain omega-1 receptor located on the alpha subunit of the GABA-A/chloride ion channel receptor complex and potentiates t-butyl-bicyclophosphorothionate (TBPS) binding.
Dosage
Hui Te Ning dosage
The dose of Hui Te Ning should be individualized. The recommended dose of Hui Te Ning for most non elderly adults is 10 mg. For certain low weight individuals, 5 mg may be a sufficient dose. Although the risk of certain adverse events associated with the use of Hui Te Ning appears to be dose dependent, the 20 mg dose has been shown to be adequately tolerated and may be considered for occasional patient who does not benefit from a trial of lower dose. Dosage above 20 mg has not been adequately evaluated and is not recommended.Hui Te Ning should be taken immediately before bedtime. Taking Hui Te Ning with or immediately after a heavy, high fat meal results in slower absorption and would be expected to reduce the effect of Hui Te Ning on sleep latency. Elderly patients and debilitated patients appear to be more sensitive to the effects of hypnotic, and respond to 5 mg of Hui Te Ning. The recommended dose for these patients is therefore 5 mg, doses over 10 mg are not recommended. For patients with mild to moderate renal impairment no dose adjustment is necessary.An initial dose of 5 mg should be given to patients concomitantly taking Cimetidine because ZalHui Te Ning clearance is reduced in this population.
Side Effects
Side effects of Hui Te Ning appear to be dose related. So, it is important to use the lowest possible effective dose, specially in the elderly. The side effects are usually mild and transient, the most common are diarrhoea, nausea, vomiting, vertigo, headache, asthenia, nightmare etc.
Toxicity
Side effects include abdominal pain, amnesia, dizziness, drowsiness, eye pain, headache, memory loss, menstrual pain, nausea, sleepiness, tingling, weakness
Precaution
Timing of drug administration: Hui Te Ning should be taken immediately before bedtime or after the patient has gone to bed.Use in the elderly and/or debilitated patients: Impaired motor and/or cognitive performance after repeated exposure or unusual sensitivity to sedative/hypnotic drugs is a concern in the treatment of elderly and/or debilitated patients. A dose of 5 mg is recommended for elderly patients to decrease the possibility of side effects. Elderly and/or debilitated patients should be monitored closely.Use in patients with concomitant illness: Hui Te Ning should be used with caution in patients with diseases or conditions that could affect metabolism or haemodynamic responses. Although preliminary studies did not reveal respiratory depressant effects at hypnotic doses of Hui Te Ning in normal subjects, caution should be observed if Hui Te Ning is prescribed to patients with compromised respiratory function, because sedative/hypnotic have the capacity to depress respiratory drive. However, patients with compromised respiration due to preexisting illness should be monitored carefully. The dose of Hui Te Ning should be reduced to 5 mg in patients with mild to moderate hepatic impairment. It is not recommended for use in patients with severe hepatic impairment.Renal impairment patients: No dose adjustment is necessary in patients with mild to moderate renal impairment. Hui Te Ning has not been adequately studied in patients with severe renal impairment.Use in patients with depression: As with other sedative or hypnotic drugs, Hui Te Ning should be administered with caution to patients exhibiting signs or symptoms of depression
Interaction
Hui Te Ning has been shown to have minimal effects on the kinetic of Warfarin, Imipramine, Ethanol, Ibuprofen, Diphenhydramine, Thioridazine, and Digoxin.
Food Interaction
- Avoid alcohol. Ingesting alcohol may increase the CNS depressant effects of zaleplon.
- Do not take with or immediately after a high-fat meal. The effects of zaleplon are reduced when taken with a high-fat meal.
[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of zaleplon.
Use in combination may result in additive central nervous system depression and
ADJUST DOSING INTERVAL: Administration of zaleplon with a high-fat or heavy meal may delay the onset of hypnotic effects.
In healthy adult subjects, administration of zaleplon with a high-fat meal resulted in a 2-hour delay in the time to reach peak plasma drug concentration (Tmax) and a 35% reduction in the peak plasma drug concentration (Cmax) compared to fasting.
Hui Te Ning systemic exposure (AUC) and elimination half-life were not significantly affected.
MANAGEMENT: Patients receiving zaleplon should be advised to avoid the consumption of alcohol.
For faster sleep onset, zaleplon should not be administered with or immediately after a high-fat or heavy meal.

Hui Te Ning Disease Interaction
Major: alcohol intox, depression, drug dependence, liver diseaseModerate: glaucoma, liver disease, resp depression, renal dysfunction
Volume of Distribution
- 1.4 L/kg
Elimination Route
Absorption Hui Te Ning is rapidly and almost completely absorbed following oral administration.
Half Life
Approximately 1 hour
Clearance
- 1 L/h/kg
Elimination Route
Hui Te Ning is metabolized primarily by the liver and undergoes significant presystemic metabolism. After oral administration, zaleplon is extensively metabolized, with less than 1% of the dose excreted unchanged in urine. Renal excretion of unchanged zaleplon accounts for less than 1% of the administered dose.
Pregnancy & Breastfeeding use
Pregnancy: There are no studies of Hui Te Ning in pregnant women; therefore, it is not recommended for use in women during pregnancy. Hui Te Ning has no established use in labour and delivery.Lactation: A study in lactating mothers indicated that the clearance and half-life of Hui Te Ning is similar to that in young normal subjects. A small amount of Hui Te Ning is excreted in breast milk, with the highest excreted amount occurring during a feeding at approximately 1 hour after Hui Te Ning administration. Since the small amount of the drug from breast milk may result in potentially important concentrations in infants, and because the effects of Hui Te Ning on a nursing infant are not known, it is not recommended in nursing mothers.
Contraindication
Hui Te Ning is contraindicated in patients with known hypersensitivity to any of its components.
Special Warning
Special Patient Group: Patients on cimetidine should receive initial dose of 5 mg at bedtime.Hepatic Impairment:
- Mild to moderate: 5 mg at bedtime.
- Severe: Contraindicated.
Paediatric use
: The safety and effectiveness of Hui Te Ning in paediatric patients have not been established.
