Phenazepam (also known as fenazepam) is a benzodiazepine drug developed in the Soviet Union in 1974 and now produced in Russia and some other CIS countries. It is used in the treatment of various neurological and psychiatric disorders, including anxiety, insomnia, and epilepsy. Phenazepam is known for its potent anxiolytic, anticonvulsant, muscle relaxant, and sedative properties.

Medical Uses

Phenazepam is primarily prescribed for the treatment of anxiety disorders, insomnia, and epileptic seizures. It is also used as a premedication before surgery to reduce anxiety and induce sedation. In some cases, it is used to manage alcohol withdrawal syndrome.

Anxiolytic

Phenazepam is effective in reducing symptoms of anxiety and is often prescribed for generalized anxiety disorder and panic disorder.

Anticonvulsant

Phenazepam has anticonvulsant properties and is used in the management of epilepsy and other seizure disorders.

Muscle Relaxant

The drug is also used as a muscle relaxant in the treatment of muscle spasms and other conditions that cause muscle stiffness.

Sedative

Phenazepam is used as a sedative to treat insomnia and to induce sedation before medical procedures.

Pharmacology

Phenazepam works by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) at the GABA_A receptor, which results in its sedative, anxiolytic, muscle relaxant, and anticonvulsant effects.

Side Effects

Common side effects of phenazepam include drowsiness, dizziness, fatigue, and muscle weakness. Long-term use can lead to tolerance, dependence, and withdrawal symptoms upon discontinuation. Overdose can result in severe respiratory depression, coma, and even death.

Legal Status

Phenazepam is a controlled substance in many countries due to its potential for abuse and dependence. In the United States, it is not approved for medical use and is classified as a Schedule IV controlled substance.

History

Phenazepam was developed in the Soviet Union in 1974 and has been used in medical practice in Russia and other CIS countries since then. It has gained some popularity in other parts of the world, often being sold online as a research chemical.
