Nov, 2023. Class 1 innovative drug Dimdazenil Capsules from Zhejiang Jingxin Pharmaceutical Co., Ltd is approved for marketing by China NPMA for short term treatment of insomnia disorders.
Dimdazenil is a benzodiazepine drug that is a partial positive allosteric modulator of gamma-aminobutyric acid type A (GABAA) receptors. It promotes sleep by partially activating GABAA receptors. The launch of this drug provides new treatment options for patients with insomnia disorders.
Insomnia disorder is a common clinical problem characterized by difficulty falling or staying asleep, or waking up too early. Insomnia disorder brings problem to estimated 10%–20% of the general population with a higher incidence in women, the elderly, and those with comorbid medical and psychiatric conditions. Dimdazenil is a novel partial positive allosteric modulator of the GABAA receptor with high affinity and moderate efficacy. As a result, Dimdazenil offers an improved safety profile compared to full agonists. Dimdazenil exhibited a favorable safety profile and was well-tolerated, without altering sleep architecture or impairing next-day vigilance and cognition. These findings demonstrate Dimdazenil’s promising potential as an insomnia therapy, with rapid sleep promotion, sustained efficacy over time, and an absence of next-day hangover effects.https://academic.oup.com/sleep/advance-article/doi/10.1093/sleep/zsad271/7326687
