Benzodiazepines are commonly used to treat alcohol withdrawal, anxiety, insomnia, panic disorders and seizures, and can be used as muscle relaxants and for conscious sedation, states Drugs.com. This class of medication works in the central nervous system by enhancing the effects of the neurotransmitter GABA, or gamma-aminobutyric, at GABA-A receptor sites.
