Correct usage and dosage of Leborexan (Daveco) and dose adjustment standards for different groups of people

Lemborexant (trade name Dayvigo) is an oral dual Orexin Receptor Antagonist (DORA), mainly used to treat insomnia in adults. By antagonizing the Orexin-1 and Orexin-2 receptors, leborexin inhibits arousal signals, helping patients fall asleep and stay asleep longer while reducing nighttime awakenings. It is well absorbed orally, has high bioavailability, and is typically used at bedtime to ensure maximum efficacy.

The recommended starting dose for adult patients is 5 mg, taken orally once a night before going to bed, and can be gradually adjusted to 10 mg/ at night based on the patient's symptoms and tolerance. The drug should be taken about 20 minutes before going to bed, and a minimum of 7 hours of sleep should be ensured after taking the drug to reduce the risk of daytime sleepiness and decreased concentration. Leborexan is not recommended for use with large amounts of alcohol or CNS depressants to reduce the risk of excessive sedation or falls.

Dose adjustment standards for different groups of people:

1.Elderly patients (≥65 years old): Due to the decline in liver metabolism, the recommended initial dose is 5 mg/late. If tolerated well and symptoms are not relieved, it can be increased to 10 as appropriate. mg, but require close monitoring for sedation and risk of falls.

2.Patients with impaired liver function: Patients with mild to moderate liver impairment (Child-Pugh A/B) may consider starting with 5 mg and adjust according to efficacy; patients with severe liver impairment (Child-Pugh C) are not recommended for use.

3. Patients with impaired renal function: Leborexen is mainly metabolized by the liver. Patients with mild to moderate renal impairment do not need to adjust the dosage. However, patients with severe renal impairment should use it with caution and closely monitor adverse reactions.

In clinical practice, it should be followed The principle of “start with a low dose and adjust according to efficacy and tolerability”. Patients should avoid getting up suddenly or driving at night to prevent accidents due to sedation or loss of concentration. During long-term use, sleep quality and daytime functional status should be regularly assessed, and potential interactions with other CNS depressant drugs or alcohol should be noted. Following the above usage and dosage adjustment standards, leborexan can significantly improve the ability to fall asleep and maintain sleep in adult patients with insomnia while ensuring safety.
