What are analgesics?
Analgesics interrupt the pain stimulus, or the brains ability to recognize the pain stimulus. Analgesics are a class of drugs which are used to only relieve pain. They act on physiology by being a “counter-irritant”. The pain relief induced by analgesics occurs either by blocking pain signals going to the brain or by interfering with the brain’s interpretation of the signals, without producing anesthesia or loss of consciousness. There are basically two kinds of analgesics: non-narcotics and narcotics.
