Concurrent anxiety and/or insomnia symptoms in women with postpartum depression (PPD) are common and associated with more severe PPD. The effects of zuranolone on concurrent anxiety and/or insomnia symptoms and on patient-perceived functional health in women with PPD in the ROBIN study are reported.

The phase 3, double-blind, randomized, placebo-controlled trial (conducted January 2017-December 2018) included women aged 18-45 years, ≤ 6 months postpartum, with PPD (onset of DSM-5-defined major depressive episode in the third trimester or ≤ 4 weeks postpartum) and baseline 17-item Hamilton Depression Rating Scale (HDRS-17) total score ≥ 26. Women were randomized 1:1 to once-daily oral zuranolone 30 mg (n = 77) or placebo (n = 76) for 14 days with follow-up through day 45. Concurrent remission of depressive and anxiety symptoms (Hamilton Anxiety Rating Scale total score ≤ 7 plus HDRS-17 total score ≤ 7 or Montgomery-Asberg Depression Rating Scale total score ≤ 10), improvement in insomnia symptoms, patient-perceived functional health, and treatment effect sizes described by number needed to treat (NNT) were assessed. Analyses were exploratory; P values are nominal.

Rates of concurrent remission of depressive and anxiety symptoms were higher with zuranolone versus placebo (P < .05) at days 3, 15, and 45; the rate of sustained concurrent remission (ie, at both days 15 and 45) was also higher with zuranolone (P < .05). Anxiety symptoms (assessed by HDRS-17 anxiety/somatization subscale and Edinburgh Postnatal Depression Scale anxiety subscale) improved with zuranolone versus placebo (P < .05) at days 3 through 45. Potential benefits on insomnia symptoms and patient-perceived functional health were observed. Day 15 NNTs were 5 for both HDRS-17 response and remission.

Zuranolone was associated with concurrent improvements in depressive and anxiety symptoms, with beneficial effects on insomnia symptoms and patient-perceived functional health in adults with PPD.

Anxiolytic Drugs: Benzodiazepines and Buspirone

Benzodiazepines are a class of anxiolytic drugs known for their rapid efficacy and high therapeutic-to-lethal dose ratio, but with a potential risk of drug dependence. These drugs are lipophilic, allowing for rapid absorption after oral administration, eventually reaching the central nervous system (CNS). Once in the CNS, benzodiazepines bind to the allosteric site of the GABAA receptor. This binding enhances the inhibitory effects of the neurotransmitter GABA. By doing so, they prevent...

Management of Insomnia01:19

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
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...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
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...

Insomnia01:27

Insomnia

Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

CNS Depressants: Barbiturates and Benzodiazepines01:14

CNS Depressants: Barbiturates and Benzodiazepines

CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...
