The CNS is responsible for processing and controlling most of our bodily functions, and consists of the nerves in the brain and spinal cord.

Central nervous system medications are used to treat the effects of a wide variety of medical conditions, including  depression, includes analgesics (pain medications), sedatives, and anticonvulsants.

There are many different types of drugs that work on the CNS, including anesthetics, anticonvulsants, antiemetics, antiparkinson agents, CNS stimulants, muscle relaxants, narcotic analgesics (pain relievers), nonnarcotic analgesics (such as acetaminophen and NSAIDs), and sedatives.
