Ativan is a kind of opioid that doctors prescribe as pain relievers in case of severe pain. It is specially prescribed to get relief from post-surgery pain and severe diseases like cancer.

This process even enhances the functioning of the two most important neurotransmitters of the brain who even participate in pain perception.
