Zolpidem tartrate is a non-benzodiazepine receptor modulator primarily used in the FDA-approved short-term treatment of insomnia aimed at patients with difficulty starting sleep. It improves measures of sleep latency, sleep duration, and reduces the number of awakenings in patients with transient insomnia. It also improves sleep quality in patients with chronic insomnia as well and can act as a minor muscle relaxant. Research also shows it is rapid and effective in restoring brain function in patients who are in a vegetative state after brain injury, as the drug has the potential to completely or partially reverse the abnormal metabolism of damaged brain cells. Usually, patients recover if the injury is in non-brain stem areas. Buy stilnox Zolpidem online in Australia
Mechanism of Action
Zolpidem, a non-benzodiazepine hypnotic agent, works as a gamma-Aminobutyric acid (GABA), a receptor chloride channel modulator/agonist that increases GABA inhibitory effects leading to sedation. It also has anticonvulsant, anxiolytic, and minor myorelaxant properties. The GABAa receptor, also called GABA-BZ, is found in the sensorimotor cortical regions, globus pallidus, inferior colliculus, pons, ventral thalamic complex, olfactory bulb, cerebellum, and substantial in the brain. The drug upregulates these receptors allowing for the sedative effects leading to the preservation of deep sleep. Buy stilnox Zolpidem online in Australia
Differing from benzodiazepines, which non-selectively bind to and activate all benzodiazepine (BZ) receptor subtypes, zolpidem in vitro binds the BZ1 receptor preferentially with a high affinity ratio of the alpha1/alpha5 subunits. The selective binding of zolpidem on the BZ1 receptor may explain the relative absence of myorelaxant and anticonvulsant effects. Overall, zolpidem is not recommended for the general population as a first-line treatment because of its high potential for abuse. Drugs like controlled-release melatonin and doxepin may be used as the first-line therapy in addition to proper sleep hygiene and cognitive behavioral therapy for patients with insomnia.

Zolpidem is rapidly absorbed by the gastrointestinal tract and has a short half-life in healthy patients. Zolpidem oral formulation is available as a tablet and an extended-release tablet. Zolpidem is also available as an oral spray, which is sprayed into the mouth over the tongue and a sublingual tablet to place under the tongue. It is administered in 5 mg or 10 mg tablets orally, depending on the patient’s sleep quality. Zolpidem is then converted to an inactive metabolite and excreted by the kidneys. Tablets are not scored. Ingestion with or immediately after food intake may slow the effects of this drug. Buy stilnox Zolpidem online in Australia
Elderly patients must receive a 5 mg dosage as their concentrations were found to be higher than young adults during clinical trials. Dosage should be changed in patients with hepatic impairment as the half-life of zolpidem was found to be a multitude of times larger than in patients with normal health. The recommended initial dose is 5 mg for women and either 5 or 10 mg for men, taken only once per night immediately before bedtime with at least 7 to 8 hours remaining before the planned time of awakening. Zolpidem clearance is lower in women.
Patients with end-stage renal failure undergoing dialysis do not need dosage adjustments, as they were not significantly different from patients with renal impairments. Zolpidem concentrations, however, should be closely watched on a daily basis.
Pediatric patients should not be given zolpidem as its effectiveness has not been found yet. In addition, the research found that hallucinations might occur in a small percentage of pediatric patients who received zolpidem. Buy stilnox Zolpidem online in Australia
Some adverse effects include anaphylaxis, changes in behavior, withdrawal, and central nervous system (CNS) depression.
In rare situations, patients have reported tongue, larynx, or glottis swelling in the form of angioedema. Also, patients have reported shortness of breath, airway closure, nausea, and vomiting. If patients report these, do not re-administer the patient with the drug. Patients who experience closure in the throat, glottis, or larynx should be sent to the emergency department.
Changes in behavior and abnormal thinking have been reported as well. In addition, patients have been found to show aggressiveness and extroversion that is abnormal for the person’s usual behavior. Patients with alcohol or drug toxicities have experienced auditory and visual hallucinations associated with strange behavior and agitation. Buy stilnox Zolpidem online in Australia
The patient was also found to experience a behavior called sleep-driving, in which the patient drives while not fully awake after intake of sedative-hypnotic with no recollection of the event. Consumption of alcohol or any other CNS depressant was found to increase these events as they enhance sedation when combined. In these cases, the drug needs to be discontinued. Patients who are depressed should also not take zolpidem as it worsens depression and suicidal ideations and actions.
