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 ...

Suzetrigine is the first non-opioid analgesic – or medication to control pain – of its class to receive federal approval in more than 20 years.
In general, until the synthesis of dihydromorphine (c. 1900), the dihydromorphinone class of opioids (1920s), and oxycodone (1916) and similar drugs, there were no other drugs in the same efficacy range as opium, morphine, and heroin, with synthetics still several years away (pethidine was invented in Germany in 1937) and opioid agonists among ...
Opioids reduce pain by binding to receptors in the brain that receive nerve signals from different parts of the body. Those chemical interactions also give rise to opioids' addictive effects.
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]
The first over-the-counter naloxone, a drug used to reverse opioid overdose, is starting to come available in retail stores and online. The medicine, with the brand name Narcan, has a suggested ...
