Temazepam is specifically indicated only for the short-term management of insomnia,. Furthermore, such management is generally predominantly associated with the symptomatic relief of transient and short-term insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings and/or early morning awakenings. In particular, the official prescribing information for temazepam typically specifies that the instructions issued for dispensed prescriptions of the medication should indicate specifically that patients are only expected to use the therapy for short periods of time - usually 7-10 days in general. Subsequently, treatment with temazepam should usually not exceed 7 to 10 consecutive days and nor should it be prescribed in quantities exceeding a one-month supply. Some regional prescribing information also notes that temazepam may be used for premedication prior to minor surgery or other related procedures.
FDA Label
Temazepam is a benzodiazepine used as a hypnotic agent in the management of insomnia. Temazepam produces CNS depression at limbic, thalamic, and hypothalamic levels of the CNS. Temazepam increases the affinity of the neurotransmitter gamma-aminobutyric acid (GABA) for GABA receptors by binding to benzodiazepine receptors. Results are sedation, hypnosis, skeletal muscle relaxation, anticonvulsant activity, and anxiolytic action. In sleep laboratory studies, the effect of temazepam was compared to placebo during a two week period. The studies demonstrated a linear dose-response improvement in total sleep time and sleep latency with substantial drug-placebo differences apparent for total sleep time and for sleep latency at higher doses of temazepam. Regardless, REM sleep was ultimately unchanged but slow wave sleep was decreased. Moreover, a transient syndrome, known as "rebound insomnia", wherein the symptoms that led to treatment with temazepam in the first place recur in an enhanced form, may happen on withdrawal of temazepam treatment. The possibility of this occurrence is in part why long term use of temazepam is not recommended due to worries over tolerance and dependence wherein patients' bodies become physiologically accustomed to the regular presence and pharmacological effect of higher and higher doses of the benzodiazepine used. The duration of hypnotic effect and the profile of unwanted adverse effects may be influenced by the distribution and elimination half-lives of the administered temazepam and any active metabolites that may be formed. When such half-lives are long, the drug or its metabolite(s) may accumulate during periods of nightly administration and be associated with impairments of cognitive and motor performance during waking hours. Conversely, if half-lives are short, the drug and metabolites would be cleared before the next dose is ingested, and carry-over effects related to sedation or CNS depression should be minimal or not present at all. However, during nightly use and for an extended period, pharmacodynamic tolerance or adaptation to some effects of benzodiazepine hypnotics may develop - which may also contribute to the possibility of 'rebound insomnia'. Consequently, if the drug has a very short elimination half-life, it is possible that a relative deficiency (for example, in relation to benzodiazepine GABA(a) receptor sites) may occur at some point in the interval between each night's use. This sequence of events may account for certain clinical findings reported happening after several weeks of nightly use of rapidly eliminated benzodiazepine hypnotics, including increased wakefulness during the last third of the night and the appearance of increased daytime anxiety.
GABA Modulators
Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) appear to have at least three allosteric sites at which modulators act: a site at which BENZODIAZEPINES act by increasing the opening frequency of GAMMA-AMINOBUTYRIC ACID-activated chloride channels; a site at which BARBITURATES act to prolong the duration of channel opening; and a site at which some steroids may act. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here. (See all compounds classified as GABA Modulators.)
Anti-Anxiety Agents
Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here. (See all compounds classified as Anti-Anxiety Agents.)
Hypnotics and Sedatives
Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety. (See all compounds classified as Hypnotics and Sedatives.)

Absorption
Studies demonstrate that between 90 to 100% of an orally administered temazepam dose is absorbed, making the medication very well absorbed. The oral administration of 15 to 45 mg temazepam resulted in rapid absorption with significant blood levels achieved in 30 minutes and peak levels at 2-3 hours. In particular, direct studies following the oral ingestion of 30 mg of temazepam revealed measurable plasma concentrations were obtained 10-20 minutes after dosing with peak plasma levels ranging between 666-982 ng/mL (with a mean of 865 ng/mL) presenting approximately 1.2-1.6 hours (with a mean of 1.5 hours) after the dosing. Finally, a dose-proportional relationship was established for the area under the plasma concentration/time curve over the 15 to 30 mg dose range.
Route of Elimination
Following a single dose, 80-90% of the dose appears in the urine, predominantly as the O-conjugate metabolite, and 3-13% of the dose appears in the faeces. Less than 2% of the dose is excreted unchanged or as N-desmethyltemazepam in the urine.
Volume of Distribution
The volume of distribution documented for temazepam is 1.3-1.5 L/kg body weight - and in particular, 43-68 L/kg for the unbound fraction.
Clearance
Studies regarding the clearance of temazepam have recorded the values of 1.03 ml/min/kg and 31 ml/min/kg for the clearance of total temazepam and the clearance of unbound temazepam, respectively.
First-pass metabolism of temazepam is minimal at approximately 5-8% of an administered dose. Nevertheless, temazepam is principally metabolized in the liver where most of the unchanged drug is directly conjugated to glucuronide and excreted in the urine. In particular, the primary metabolite present in the blood is the O-conjugate of temazepam. Less than 5% of the drug is demethylated to oxazepam and subsequently eliminated as the glucuronide. Regardless, the glucuronides of temazepam have no demonstrable CNS activity and it is believed that no active metabolites are formed in general. Since temazepam mainly undergoes Phase II conjugation reactions, it is proposed that it is devoid of CYP450 interactions.
Temazepam is a known human metabolite of diazepam.

The terminal half-life determined for temazepam is recorded as being between 3.5-18 hours, with a mean of 9 hours.
Gamma-Aminobutyric acid (GABA) is considered the principal inhibitory neurotransmitter in the human body. When GABA binds to GABA(a) receptors found in neuron synapses, chloride ions are conducted across neuron cell membranes via an ion channel in the receptors. With enough chloride ions conducted, the local, associated neuron membrane potentials are hyperpolarized - making it more difficult or less likely for action potentials to fire, ultimately resulting in less excitation of the neurons. Subsequently, benzodiazepines like temazepam can bind to benzodiazepine receptors that are components of various varieties of GABA(a) receptors. This binding acts to enhance the effects of GABA by increasing GABA affinity for the GABA(a) receptor, which ultimately enhances GABA ligand binding at the receptors. This enhanced ligand binding of the inhibitory neurotransmitter GABA to the receptors increases the aforementioned chloride ion conduction (perhaps reportedly via an increase in the frequency of the chloride channel opening), resulting in a hyperpolarized cell membrane that prevents further excitation of the associated neuron cells. Combined with the notion that such benzodiazepine receptor associated GABA(a) receptors exist both peripherally and in the CNS, this activity consequently facilitates various effects like sedation, hypnosis, skeletal muscle relaxation, anticonvulsant activity, and anxiolytic action.

A Temazepam DMF (Drug Master File) is a document detailing the whole manufacturing process of Temazepam active pharmaceutical ingredient (API) in detail. Different forms of Temazepam DMFs exist exist since differing nations have different regulations, such as Temazepam USDMF, ASMF (EDMF), JDMF, CDMF, etc.
A Temazepam DMF submitted to regulatory agencies in the US is known as a USDMF. Temazepam USDMF includes data on Temazepam's chemical properties, information on the facilities and procedures used, and details about packaging and storage. The Temazepam USDMF is kept confidential to protect the manufacturer’s intellectual property.
click here to find a list of Temazepam suppliers with USDMF on PharmaCompass.
A Temazepam CEP of the European Pharmacopoeia monograph is often referred to as a Temazepam Certificate of Suitability (COS). The purpose of a Temazepam CEP is to show that the European Pharmacopoeia monograph adequately controls the purity of Temazepam EP produced by a given manufacturer. Suppliers of raw materials can prove the suitability of Temazepam to their clients by showing that a Temazepam CEP has been issued for it. The manufacturer submits a Temazepam CEP (COS) as part of the market authorization procedure, and it takes on the role of a Temazepam CEP holder for the record. Additionally, the data presented in the Temazepam CEP (COS) is managed confidentially and offers a centralized system acknowledged by numerous nations, exactly like the Temazepam DMF.
A Temazepam CEP (COS) is recognised by all 36 nations that make up the European Pharmacopoeia Convention. Temazepam CEPs may be accepted in nations that are not members of the Ph. Eur. at the discretion of the authorities there.
click here to find a list of Temazepam suppliers with CEP (COS) on PharmaCompass.
A Temazepam written confirmation (Temazepam WC) is an official document issued by a regulatory agency to a Temazepam manufacturer, verifying that the manufacturing facility of a Temazepam active pharmaceutical ingredient (API) adheres to the Good Manufacturing Practices (GMP) regulations of the importing country. When exporting Temazepam APIs or Temazepam finished pharmaceutical products to another nation, regulatory agencies frequently require a Temazepam WC (written confirmation) as part of the regulatory process.
