Sedatives and Hypnotics Drugs: Miscellaneous Agents01:17

Sedatives and Hypnotics Drugs: Miscellaneous Agents

132
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...

Management of Insomnia

223
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

239
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...

CNS Depressants: Barbiturates and Benzodiazepines01:14

CNS Depressants: Barbiturates and Benzodiazepines

183
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...

Stages of General Anesthesia01:22

Stages of General Anesthesia

317
Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

Sedatives and Hypnotics Drugs: Benzodiazepines

162
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
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...
