NITRAZEPAM belongs to a group of medications called 'benzodiazepines' (BZD) primarily used to treat anxiety disorders, insomnia and prevention of seizures (fits) due to epilepsy. An anxiety disorder is a mental health disorder characterized by excessive fear or worry, that affects individual daily activities. Epilepsy is a brain-related neurological disorder characterized by episodes of seizures (fits) due to a chemical change in the brain cells (neurons) that leads to a sudden surge of electrical activity in the brain followed by sudden jerky movements of limbs or a part of the body. Insomnia is a sleeping disorder in which a person finds difficulty in feeling asleep or staying asleep.
