Any man-made drug that exhibits properties of opium and is given to treat pain.
A type of medication related to opium. Opioids are strong analgesics. Opioids include morphine, codeine, and a large number of synthetic (man-made) drugs like methadone and fentanyl.
a synthetic narcotic drug
any compound, peptide or otherwise, which, while not containing the fundamental morphine or thebaine structure, possesses some affinity for any, or all, of the opioid receptor subtypes. Common opioids are endorphin, fentanyl and methadone.
a drug used to relieve or manage pain that elicits a physiologic effect via interaction with one of three subtypes of opioid receptors found in the body
A synthetic or naturally occurring chemical in the brain that may reduce pain and induce sleep. Placebo: An inactive pill or sham procedure given to a participant in a research study as part of a test of the effects of another substance or treatment. Scientists use placebos to get a true picture of how the substance or treatment under investigation affects participants. In recent years, the definition of placebo has been expanded to include such things as aspects of interactions between patients and their health care providers that may affect their expectations and the study's outcomes.
A class of chemicals that has narcotic, analgesic, soporific (sleep-causing) and other effects on the body. Also a class of natural substances, such as endorphins, produced by the body in response to stress or pain.
class of drugs including heroin, methadone, codeine, pethidine, morphine etc.
Prescription medication used to treat moderate to severe pain. (e.g. codeine, morphine, hydrocodone)
Referring to synthetic narcotics that act in a similar way to opiates but are not derived from opium. Opioids such as morphine are used to control severe pain.
any agent that binds to opioid receptors found principally in the central nervous system and gastrointestinal tract. The term is applied to opiates and their synthetic equivalents, with effects similar to those of morphine, in particular the capacity to relieve pain. They include substances such as fentanyls, methadone, and pethidine (UNODC definition).
A drug, hormone, or other chemical substance having sedative or narcotic effects similar to those containing opium or its derivatives; a natural brain opiate.
a class of drugs (e.g., heroin, codeine, methadone) that are derived from the opium poppy plant, contain opium, or are produced synthetically and have opium-like effects. Opioid drugs relieve pain, dull the senses and induce sleep.
A synthetic narcotic that resembles the naturally occurring opiates and binds to the opiate receptor on cell surface eliciting its effect.
Any derivative of opium or any narcotic with effects similar to those of an opiate.
A broad term encompassing natural and synthetic morphine-like compounds, known to inhibit the transmission of pain signals in the spinal cord and brain through their action at opioid receptor sites.
A scientific term that refers to both natural and synthetic drugs whose effects are mediated by specific receptors in the central and peripheral nervous systems, including codeine, morphine, oxycodone, and fentanyl.
1. A synthetic narcotic that resembles the naturally occurring opiates. 2. Any substance that binds to or otherwise affects the opiate receptors on the surface of the cell. See the entire definition of Opioid
a synthetic narcotic analgesic, also used in the general sense for all narcotic analgesics.
A drug with opiumlike qualities, which means that it reduces pain, causes relaxation or sleepiness, and carries an addictive potential. Opioids may be either: Derived from opiates or Chemically related to opiates or opium. Opioids include some prescription painkillers, such as oxycodone and hydrocodone. Buprenorphine, methadone, and heroin are also opioids.
Any man-made drug that acts like opium and is given to treat pain.
A drug used to treat moderate to severe pain. Opioids are similar to opiates such as morphine and codeine, but they do not contain and are not made from opium.
Any chemical that has opiate-like effects; commonly used to refer to endogenous neurochemicals that activate opiate receptors.
A synthetic drug that is used to treat moderate to severe pain. Opioids are similar to opiates such as morphine and codeine.
A class of strong pain medicines derived from Opium. Morphine and Codeine would be examples.
An opioid is a chemical substance that has a morphine-like action in the body. The main use is for pain relief. These agents work by binding to opioid receptors, which are found principally in the central nervous system and the gastrointestinal tract.
