Concomitant administration with benzodiazepine agonists may enhance the risk of extreme sedation, respiratory depression, and coma
It may enhance sedation when combined with oxycodone
it decreases the rate of elimination of pidotimod
CYP3A strong enhancers of the small intestine may reduce the bioavailability of zaleplon
the excretion rate of gadopentetic acid may be decreased by zaleplon, potentially leading to a higher serum level
zaleplon may lower the excretion rate of ioxilan, which could result in a raised serum level
zaleplon may lower the excretion rate of phylloquinone, potentially leading to higher serum levels
muzolimine may increase the excretion rate of zaleplon, potentially resulting in a lower serum level and a potential reduction in efficacy
mycophenolic acid has the potential to decrease the excretion rate of zaleplon, potentially resulting in higher serum levels
zaleplon may lower the excretion rate of n-acetyl tyrosine, potentially resulting in elevated serum levels
zaleplon may lower the excretion rate of sulbactam, potentially resulting in a higher serum level
when used with fosnetupitant, zaleplon's metabolism can be lowered
the risk or extent of CNS depression can be heightened when butalbital is used in conjunction with zaleplon
procarbazine: they may increase the CNS depressant effect of CNS Depressants
It may enhance the risk of adverse effects when combined with Platelets inhibitors
It may enhance the risk of adverse effects when combined with Platelets inhibitors
It may enhance the risk of adverse effects when combined with Platelets inhibitors
It may enhance the risk of adverse effects when combined with Platelets inhibitors
It may enhance the risk of adverse effects when combined with Platelets inhibitors
glucagon: they may increase the CNS depressant effect of CNS Depressants
hyaluronidase: they may increase the CNS depressant effect of CNS Depressants
the rate of excretion of aurothioglucose may be reduced with zaleplon
the rate of excretion of inositol may be reduced
imidazole salicylate may slow down the pace at which allopurinol is excreted, which could lead to a rise in the blood level of the drug
the excretory rate of bufylline may be increased by zaleplon
metronidazole enhances the effect of zaleplon by altering the intestinal or hepatic CYP3A4 enzyme metabolism
Action and Spectrum:
Zaleplon binds with GABA receptors in the brain. It increases GABA effect to regulate CNS inhibition.
It opens chloride channels to reduce excitability and promotes sleep induction.
Adverse reaction:
>10%:
Headache
1-10%:
Dizziness
Nausea
Abdominal pain
Dysmenorrhea
Eye pain
Weakness
Tremor
<1%:
Fever
Photosensitivity
Amnesia
Vertigo
Epistaxis
Depersonalization
Anorexia
Colitis
Hallucination
Hypesthesia
Ear pain
Hyperacusis
Parosmia
Black box warning:
Therapy may lead to complex sleep behaviours such as sleepwalking and sleep-driving to cause serious injuries.
In such cases discontinue therapy immediately if patient experiences a complex sleep behaviour.
Contraindications/caution:
Contraindications:
Cautions:
Pregnancy Warnings:
Pregnancy category: C
Lactation: Small amount secreted in breast milk
Pregnancy categories:
Pharmacology: Zaleplon selectively binds to omega-1 receptor on GABA-A/chloride ion channel. It modulates GABA-BZD receptor chloride channel to induce action.
Pharmacodynamics: Zaleplon quickly induces sleep within 30 minutes of ingestion. It causes CNS depression that occurs into sedation, drowsiness, and coordination issues.
Pharmacokinetic:
Absorption:
It reaches peak plasma time in 1 hours.
Distribution:
It shows protein bound of 45% to 75%.
Metabolism:
It metabolized by aldehyde oxidase.
Excretion and elimination:
It is excreted through urine route.
Administration:
It is available in capsule form for oral use.

Generic Name: zaleplon
Why do we use zaleplon?
Zaleplon is used to manage sleep disorders i.e., insomnia.
It is indicated as short-term course for acute stress or temporary sleep pattern changes.
Both our subscription plans include Free CME/CPD AMA PRA Category 1 credits.
On course completion, you will receive a full-sized presentation quality digital certificate.
A dynamic medical simulation platform designed to train healthcare professionals and students to effectively run code situations through an immersive hands-on experience in a live, interactive 3D environment.
When you have your licenses, certificates and CMEs in one place, it's easier to track your career growth. You can easily share these with hospitals as well, using your medtigo app.
