Calzapam is a brand name for a medication that contains the active ingredient diazepam, which is a benzodiazepine. It is primarily used to treat anxiety, muscle spasms, and seizure disorders, and it may also be prescribed for short-term relief of insomnia. Like other benzodiazepines, calzapam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, leading to a calming effect. Due to its potential for dependence and withdrawal symptoms, it is generally recommended for short-term use under medical supervision.
