Quazepam is indicated for the treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings. Quazepam interact preferentially with the benzodiazepine-1 (BZ1) receptors. Most common adverse reactions (>1%): drowsiness, headache, fatigue, dizziness, dry mouth, dyspepsia. Downward of CAN depressant dose adjustment may be necessary due to additive effects.
A benzodiazepine used as a hypnotic agent. It is of medium potency and is highly lipid soluble, enabling rapid penetration of the blood - brain barrier and resulting in rapid onset of effects. Because its metabolic products are eliminated slowly, quazepam may accumulate in the body, leading to unwanted daytime sedation. U.S. trade name: Doral.
Quazepam is unique in its drug properties in two ways:
- Several medications from the same class of drugs have an effect called rebound insomnia. This means that the insomnia becomes worse than the original insomnia when the drug is used for extended periods. Quazepam has a minimal tendency to cause rebound insomnia.
- Secondly, quazepam is eliminated from the body slowly. This gives quazepam advantage over certain other medications in the benzodiazepine class, such as alprazolam or halazepam, in that patients do not experience earlymorning insomnia, since there is still enough medication to induce sleep in the very early morning hours.
Quazepam's sedating effect that reduces insomnia lasts only for about four weeks of continuous use. The medication is most effective for an intermediate-term treatment of insomnia (two weeks), rather than a long duration of treatment of over four weeks. Hence, long-term treatment for insomnia with quazepam should be avoided.
Quazepam comes in 7.5-mg and 15-mg tablets
Doral is a prescription drug and the brand name for the generic drug quazepam. It is a benzodiazepine that is used to treat sleep problems in people who have difficulties falling asleep, continually wake very early in the morning, or have trouble staying asleep at night. Doral comes in the form of an orange-colored tablet and a typical dose is usually 7.5 mg, but that can also be increased to 15 mg if necessary. Since it is a longer-acting benzodiazepine, it generally causes fewer side effects than other benzodiazepines, but if it is used incorrectly or purposely abused, it can still cause dependence and addiction. If you are taking this medication for insomnia, it is extremely important that you use it exactly as it was prescribed by your doctor. People who misuse benzodiazepines like Doral or even who use them as prescribed for an extended amount of time can become addicted. Doral is similar to the sleep medications Ambien and Sonata and works by targeting only the GABA receptors in the brain that are responsible for sleep. When the drug is consumed, it provides the user with a calming and sedating effect that helps them fall asleep and stay asleep. Compared to other benzodiazepines, Doral has a lower risk of addiction, but dependence and addiction are still very possible. A person may develop a Doral addiction if he or she takes very large dosages of the drug or uses it for a long period of time.

Addiction, abuse, and misuse
As with most benzodiazepines, quazepam therapy has not been associated with serum aminotransferase or alkaline phosphatase elevations, and clinically apparent liver injury from quazepam has not been reported and must be very rare, if it occurs at all.
Quazepam, like other benzodiazepines, is rarely associated with serum ALT elevations, and clinically apparent liver injury from quazepam is extremely rare, if it occurs at all. There have been no case reports of symptomatic, acute liver injury from quazepam, but it has not been available for very long. Cases of clinically apparent liver injury have been reported with other benzodiazepines including alprazolam, chlordiazepoxide, clonazepam, diazepam, flurazepam and triazolam. The clinical pattern of acute liver injury from benzodiazepines is typically cholestatic and mild-to-moderate in severity with a latency of 1 to 6 months. Fever and rash are uncommon as is autoantibody formation.
E Likelihood score: E (unlikely cause of clinically apparent liver injury).
Appropriate studies have not been performed on the relationship of age to the effects of quazepam in children.
Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of quazepam in the elderly. However, elderly patients are more likely to have confusion, dizziness, or falls and age-related heart, liver, or kidney problems which may require an adjustment in the dose for patients receiving quazepam.
Other Medical Problems:
The presence of other medical problems may affect the use of this medicine. Make sure you tell your doctor if you have any other medical problems, especially:
- Alcohol abuse, history of
- Breathing problems or lung disease
- Drug abuse or dependence, history of
- Mental health problems - Use with caution. May make these conditions worse
- Pulmonary insufficiency
- Sleep apnea (temporary stopping of breathing during sleep) - Should not be used in patients with these conditions
Summary of Use During Lactation:
No information is available on the long-term use of quazepam during breastfeeding.
Because the drug and metabolites could accumulate in the breastfed infant, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
Quazepam has a half-life of about 41 hours and is extensively metabolized to 2-oxoquazepam, which is in turn metabolized to desalkylflurazepam having a half-life of 47 to 100 hours.
Alternate Drugs to Consider:
|Chemical Safety Summary:
|Main risks and target organs:
|Central nervous system, causing depression of respiration and consciousness.
|Summary of clinical effects:
|Central nervous system (CNS) depression and coma, or paradoxical excitation, but deaths are rare when benzodiazepines are taken alone. Deep coma and other manifestations of severe CNS depression are rare. Sedation, somnolence, diplopia, dysarthria, ataxia and intellectual impairment are the most common adverse effects of benzodiazepines. Overdose in adults frequently involves co- ingestion of other CNS depressants, which act synergistically to increase toxicity. Elderly and very young children are more susceptible to the CNS depressant action. Intravenous administration of even therapeutic doses of benzodiazepines may produce apnoea and hypotension. Dependence may develop with regular use of benzodiazepines, even in therapeutic doses for short periods. If benzodiazepines are discontinued abruptly after regular use, withdrawal symptoms may develop. The amnesia produced by benzodiazepines can have medico-legal consequences.
- Quazepam is only found in individuals that have used or taken this drug
- It is a drug which is a benzodiazepine derivative
- It induces impairment of motor function and has hypnotic properties
- Quazepam is used to treat insomnia
- Benzodiazepines bind nonspecifically to benzodiazepine receptors, which affects muscle relaxation, anticonvulsant activity, motor coordination, and memory
- QUAZEPAM CIV
- A relatively long-acting benzodiazepine derivative
- Developed in the 1970s
- Patented in 1970 and came into medical use in 1985
- Indicated for the treatment of insomnia including sleep induction and sleep maintenance
Quazepam induces impairment of motor function and has relatively (and uniquely) selective hypnotic and anticonvulsant properties with considerably less overdose potential than other benzodiazepines (due to its novel receptor-subtype selectively).
- Quazepam is an effective hypnotic which induces and maintains sleep without disruption of the sleep architecture
- Usual dosage is 7.5 to 15 mg orally at bedtime
- Quazepam causes significantly less drug tolerance and less withdrawal symptoms including less rebound insomnia upon discontinuation compared to other benzodiazepines
Short-acting hypnotics often cause next day rebound anxiety. Quazepam due to its pharmacological profile does not cause next day rebound withdrawal effects during treatment.
Quazepam is a drug with the potential for misuse. Two types of drug misuse can occur either recreational misuse is where the drug is taken to achieve a high or when the drug is continued long term against medical advice.
