Diazepam is a medication that belongs to the benzodiazepine class of drugs. It is commonly used to treat anxiety, muscle spasms, seizures, and alcohol withdrawal symptoms. Diazepam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain, which helps to reduce the activity of certain nerve cells and produce a calming effect.Diazepam is available in various forms, including tablets, capsules, and injections. It is important to take this medication exactly as prescribed by a healthcare provider, as misuse or abuse can lead to serious side effects and addiction.
