Which among the following may be used as a sedatives-hypnotic?
Correct Answer: Zolpidem
Description: Zolpidem
The hypnotic zolpidem is not structurally related to benzodiazepines, but it selectively binds to the benzodiazepine receptor subtype BZ1. Zolpidem has no anticonvulsant or muscle-relaxing properties.
It shows few withdrawal effects, exhibits minimal rebound insomnia, and little tolerance occurs with prolonged use. Zolpidem is rapidly absorbed from the gastrointestinal (GI) tract, and it has a rapid onset of action and short elimination half-life (about 2 to 3 hours). It provides a hypnotic effect for approximately 5 hours.
Zolmitriptan is one of the drugs used to treat migraine headache.
Zileuton is a selective and specific inhibitor of 5-lipoxygenase, preventing the formation of both LTB4 and the cysteinyl leukotrienes. These drugs are useful for treatment of asthma in patients who are poorly controlled by conventional therapy.
Key Concept:
Zolpidem (AMBIEN, others) is a non-benzodiazepine sedative-hypnotic drug.
