As manufacturer of Nitrazepam we hereby state the following facts about the drug:

Nitrazepam belongs to a group of medicines called benzodiazepines. It is a 1,4-benzodiazepinone that is 1,3-dihydro-2H-1,4-benzodiazepin-2-one which is substituted at positions 5 and 7 by phenyl and nitro groups, respectively. It is used as a hypnotic for the short-term management of insomnia and for the treatment of epileptic spasms in infants (West's syndrome). It has a role as an anticonvulsant, an antispasmodic drug, a GABA modulator, a sedative and a drug metabolite.

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.

Therapeutic uses and effectiveness:

  • Used to treat short-term sleeping problems (insomnia), such as difficulty falling asleep, frequent awakenings during the night, and early-morning awakening. Nitrazepam shortens the time required to fall asleep and lengthens the duration of sleep
  • Nitrazepam is a powerful hypnotic drug which possesses strong sedative, anxiolytic, amnestic, anticonvulsant, and skeletal muscle relaxant properties
  • It is also useful for the management of myoclonic seizures
    • 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
    • GABA modulators: Substances that do not act as agonists or antagonists but do affect the GABA receptor-ionophore complex
    • Hypnotics and sedatives: Drugs used to induce drowsiness or sleep or to reduce psychological excitement or anxiety
    • Anticonvulsants: Drugs used to prevent seizures or reduce their severity

Global Calcium is a leading manufacturer of this drug. We manufacture this pharmaceutical drug and make it available to domestic and overseas market
