4 Drug and Medication Information
4.1 Drug Indication

Used to treat short-term sleeping problems (insomnia), such as difficulty falling asleep, frequent awakenings during the night, and early-morning awakening.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Nitrazepam is a type of benzodiazepine drug. It is a powerful hypnotic drug which possesses strong sedative, anxiolytic, amnestic, anticonvulsant, and skeletal muscle relaxant properties. Nitrazepam shortens the time required to fall asleep and lengthens the duration of sleep. It is also useful for the management of myoclonic seizures.


5.2 MeSH Pharmacological Classification

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.)


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.)


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.)


Anticonvulsants

Drugs used to prevent SEIZURES or reduce their severity. (See all compounds classified as Anticonvulsants.)

5.4 Absorption, Distribution and Excretion

Absorption

Bioavailability is 53-94% following oral administration.


5.5 Biological Half-Life

15-38 hours (mean elimination half life 26 hours).


5.6 Mechanism of Action

Nitrazepam belongs to a group of medicines called benzodiazepines. This drug affects central benzodiazepine receptors, which are associated with inhibitory GABA (gamma amino butyric acid)receptors, leading to enhanced GABA binding activity. GABA is a major neurotransmitter in the brain, which causes somnolence, relaxation of muscles, a decrease in anxiety and general central nervous system depression. Nitrazepam has anticonvulsant properties that may be attributed to its ability to bind to voltage-dependent sodium channels. Sustained repetitive firing seems to be limited by benzodiazepines effect of slowing recovery of sodium channels from inactivation.
