Zaleplon is classified as a non-benzodiazepine hypnotic in the pyrazolopyrimidine chemical class. It is delivered in capsule form and is usually taken with food. While the exact chemical mechanism of zaleplon is not yet fully understood, it appears to work by increasing the availability and effectiveness of the neurotransmitter GABA inside the brain. This increased availability aids in slowing neural activity within the brain and depressing certain other functions of the central nervous system. Patients should not discontinue using zaleplon abruptly; the medication can be habit-forming and may cause serious withdrawal symptoms if proper care is not used.
Uses for Zaleplon
Zaleplon is most commonly prescribed for insomnia. As a result, it can be useful for patients with severe or chronic back pain that interferes with regular sleep. While zaleplon is not thought to directly relieve back pain, it can provide an added degree of comfort to patients in managing their treatment for spinal injuries, muscle strains and other serious back disorders.
H2: Contraindications for Zaleplon
Zaleplon should not be used by patients who are allergic to it or any other non-benzodiazepine hypnotic medication. Additionally, zaleplon may not be right for patients suffering from the following conditions:
- Liver problems
- Severely high or low blood pressure
- Respiratory difficulties, including asthma and emphysema
- Addictive behaviors, including drug and alcohol abuse
Elderly patients may experience heightened susceptibility to the effects of zaleplon and should take extra precautions during use. As with any prescription medication, zaleplon should be used only under the supervision of a physician. The effects of zaleplon on fetal development and on infants are not known; as a result, pregnant and nursing women should not take this medication.
Known Drug Interactions
Zaleplon is known to interact with a number of other medications, herbal supplements and other substance. Patients should inform their physician and pharmacist if they are currently taking any of the following:
- Prescription or nonprescription antihistamines
- Cough and cold medications
- Allergy pills

These medications may amplify the effects of zaleplon and cause severe depression of the nervous system, leading to respiratory depression in susceptible individuals. It is essential to notify appropriate medical personnel immediately if any signs of respiratory distress occur in patients using zaleplon.
Side Effects of Zaleplon

However, the drowsiness and sleepiness caused by zaleplon can cause serious difficulties for patients who attempt to continue regular activities while using the medication.
