Pain can be relieved through a combination of medicines that help to relieve pain. There are two main groups of pain killers:

•  
  • Narcotic analgesics(Morphine, Tramadol) Narcotic analgesics stimulate the production of endorphins that reduce pain and cause the feeling of euphoria. Narcotic pain killers are indicated to relieve severe pain.
  • Non steroidal anti-inflammatory drugs or NSAID's(ibuprofen, paracetamol, acid acetylsalicylic). These medicines exert analgesic action via inhibiting the enzyme called cyclooxygenase type 1 or cyclooxygenase type 2. By inhibiting cyclooxygenase NSAID's decrease the production of inflammatory mediators called prostoglandins. Prostoglandins work by increasing the excitability threshold of the pain receptors. NSAID's are used for the treatment and relieve of mold and moderate pain.
