It was discovered to have that ability and since then, a lot of studies have subsequently been carried out to evaluate its effectiveness in treatments of psychiatric disorders.

How does D-cycloserine work?

D-cycloserine works by partially stimulating the N-methyl-D-aspartic acid abbreviated as NMDA. The receptors are located at the base of the basolateral nucleus of the amygdala. These receptors are glutaminergic in nature, and the D-cycloserine influences the glycine binding sites. These sites that are affected by D-cycloserine are important for opening the NMDA channels. When the channels are open, there is an increased neurotransmission that is excitatory. The D-cycloserine, studies have revealed, possess a greater efficacy at the NR1/NR2 receptors, more than even the endogenous agonists such as D-serine and glycine.

The thinking behind this step is that the extinction of addiction to drugs is similar to the extermination of fear. Trials have already been made in animals as well as human models. In the light of the evidence that there were mixed results in studies conducted in 2006 and 2010, more studies are being conducted to determine conclusively if this drug can be used to combat the drug addiction menace.
