This is a list of opioids, opioid antagonists and inverse agonists. Opium and poppy straw derivatives. Seedhead of opium poppy with white latex.
Unique to each opioid is its distinct binding affinity to the various classes of opioid receptors (e.g. the μ, κ, and δ opioid receptors are activated at different magnitudes according to the specific receptor binding affinities of the opioid). For example, the opiate alkaloid morphine exhibits high-affinity binding to the μ-opioid receptor ...
Opiates with opioid activity are mainly used for pain management with the premise that there will be benefits for both pain & function that will outweigh the risks to the patient. [25] Another indication is symptomatic relief of shortage of breath, both in the acute setting (for example, pulmonary edema) and in terminally ill patients. [26] [27]
This is the list of Schedule II controlled substances in the United States as defined by the Controlled Substances Act. [1] The following findings are required, by section 202 of that Act, for substances to be placed in this schedule:
Opioids. ACSCN Drug 9815 Acetyl-alpha-methylfentanyl [3] 9601 Acetylmethadol [4] [note 1] 9821 Acetylfentanyl [5] 9811 Acryl fentanyl [6] 9551 AH-7921 [7] 9602
The structure-activity relationship of the drug class has been explored to a reasonable extent. The optimal substitution pattern is fairly tightly defined (i.e. N,N-diethyl on the amine nitrogen, 4-ethoxy on the benzyl ring and 5-nitro on the benzimidazole ring), but even derivatives incorporating only some of these features are still potent opioids.
The opioid epidemic took hold in the U.S. in the 1990s. Percocet, OxyContin and Opana became commonplace wherever chronic pain met a chronic lack of access to quality health care, especially in Appalachia. The Centers for Disease Control and Prevention calls the prescription opioid epidemic the worst of its kind in U.S. history.
The best known agonist-antagonists are opioids. Examples of such opioids are: pentazocine, agonist at the kappa (κ) and sigma (σ) and has a weak antagonist action at the mu opioid receptor (μ) [4] butorphanol, partial agonist at μ- and a pure agonist at κ-opioid receptor and antagonist activity at the delta opioid receptor (δ) [5]
