Abstract:
Dimdazenil (Junoenil®) is a small-molecule, oral, partial positive allosteric modulator of the gamma-aminobutyric acid (GABA)A receptor that is being developed by Zhejiang Jingxin Pharmaceutical in collaboration with Evotec for the treatment of insomnia. Dimdazenil is designed to overcome issues associated with full GABAA receptor agonists, such as tolerance, withdrawal symptoms and associated adverse effects. On 29 November 2023, dimdazenil oral capsules received approval in China for the short-term treatment of insomnia. This article summarizes the milestones in the development of dimdazenil leading to this first approval for insomnia.

Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
