A drug may be classified by the chemical type of the active ingredient or by the way it is used to treat a particular condition. Each drug can be classified into one or more drug classes.
Benzodiazepines are a class of agents that work on the central nervous system, acting selectively on gamma-aminobutyric acid-A (GABA-A) receptors in the brain. It enhances response to the inhibitory neurotransmitter GABA, by opening GABA-activated chloride channels and allowing chloride ions to enter the neuron, making the neuron negatively charged and resistant to excitation.
Benzodiazepines are similar in pharmacological action but have different potencies, and some benzodiazepine work better in treatment of particular conditions. Benzodiazepines are used as sedatives, hypnotics, anxiolytics, anticonvulsants and muscle relaxants.
