Barbiturates

Barbiturates were first made in the mid 1890s and were widely used to treat anxiety. All barbiturates inhibit the activity of neurones in the brain by exaggerating the actions of a naturally occurring neurotransmitter: gamma-aminobutyric acid (GABA). There are many different barbiturates, which have different uses depending on how long they last in the body.
