Somnifacient

Etizolam is a benzodiazepine somnifacient for treating insomnia.

Somnifacient (from Latin somnus, sleep[1]), also known as sedatives or sleeping pills, is a class of medications that induces sleep. It is mainly used for treatment of insomnia. Examples of somnifacients include benzodiazepines, barbiturates and antihistamines.

Around 2-6% of adults with insomnia use somnifacients to aid sleep.[2] However, somnifacients only benefit transient or short-term insomnia but not chronic insomnia.[3] It is because somnifacients lack supportive evidence for sleep aids in chronic insomnia, and chronic use of somnifacients leads to many adverse effects.[4][5] When somnifacient is used, it should be combined with Cognitive behavioural therapy for insomnia (CBT-I) and healthy sleeping habits but not solely used due to potential severe adverse effects.[6][7]

Somnifacients are mainly in oral formulations, including tablets, capsules, solution and suspension, with an onset time within an hour.[8] One or two doses of somnifacients should be given for transient insomnia, while doses indicated for a week should be given for short-term insomnia.[9]
