特許 係属中 An opioid is any chemical such as morphine that resembles opiates in its pharmacological effects. Opioids work by binding to opioid receptors, which are found principally in the central and peripheral nervous system and the gastrointestinal tract. These receptors mediate both the psychoactive and the somatic effects of opioids.
