Diazepam is a medication that belongs to the benzodiazepine class of drugs. It is commonly prescribed to treat anxiety disorders, muscle spasms, seizures, and alcohol withdrawal symptoms.

Diazepam works by enhancing the activity of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA). GABA helps to calm excessive brain activity, leading to a sedative and calming effect. This helps to alleviate anxiety, relax muscles, and prevent seizures.
