Real Life Pharmacology - Pharmacology Education For Health Care Professionals

On this episode, I discuss the pharmacology of zaleplon including side effects, drug interactions, and important clinical pearls. Zaleplon is a non-benzodiazepine sleep aide commonly known as Sonata. It is commonly used for sedation and the management of insomnia. Zaleplon is a controlled medication, with a high risk for dependence, and because of that, it is best used to treat short-term insomnia. The pharmacology of zaleplon is similar to other sleep aids like Ambien, and Lunesta; they all have an impact on GABA. Specifically, zaleplon regulates the GABABZ receptor. The GABABZ receptor has been shown to be responsible for the pharmacological properties of benzodiazepines which produce sedative, anxiolytic, relaxant, and anticonvulsive effects. For pharmacokinetics, zaleplon has a general onset of action around 30-60 minutes, because of that it is best dosed closer to bedtime.  For sedatives, and other drugs similar to zaleplon, it is generally better to start at lower doses in geriatrics and smaller p
