Which of the following medications is marketed under the brand name Restoril?

Temazepam is the medication marketed under the brand name Restoril. It is a benzodiazepine primarily used to treat insomnia, helping patients fall asleep and stay asleep throughout the night. The effectiveness of temazepam in inducing sleep is due to its ability to enhance the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) at GABA-A receptors in the brain, leading to sedative, anxiolytic, and muscle relaxant properties.

While the other medications listed also belong to classes of drugs that can affect the central nervous system, they are used for different indications and are marketed under different brand names. Triazolam, for instance, is another benzodiazepine that is used for insomnia but is marketed under a different name, and clorazepate is mainly used for anxiety and seizure disorders. Pentazocine is an opioid analgesic used for pain management and is not related to the treatment of sleep disorders. Understanding the specific uses and brand names of these medications is important for proper patient care and management.
