Valium is a benzodiazepine drug that acts directly on the central nervous system. It increases neurotransmitter activity and function and GABA (Gama Amminobutaric Acid) levels, calms the brain and nerve cells and reduces anxiety and hyperactivity. Balanced GABA levels affect the different receptor spots in the brain's automatic function and reflex action, inducing a relaxing effect on the body and mind.
