Opiod analgesics, also called narcotics, are drugs usually used for treating pain. Opiod analgesics are defined as "all of the natural and semisynthetic alkaloid derivatives from opium, their pharmacologically similar synthetic surrogates, as well as all other compounds whose opiod-like actions are blocked by the nonselective opiod receptor antagonist naloxone.[1]

Pharmacology

There a several cell surface receptors for opiods. All are are G-protein-coupled receptors. The major subtypes of opiod receptors are:

  • Mu receptors are responsible for analgesia.
  • Delta
  • Kappa
