 Context examples 

The hydrochloride salt form of nalbuphine, a synthetic phenanthrene opioid with opiate agonist and antagonist effects, used to treat moderate to severe pain and provide preoperative and postoperative analgesia and sedation.

(Nalbuphine Hydrochloride, NCI Thesaurus)

This results in reversal of the effects of the opioids, including reversal of analgesia, euphoria, respiratory depression, hypotension, sedation and physical dependence.

(Nalmefene Hydrochloride, NCI Thesaurus)

In addition, morphine closes N-type voltage-gated calcium channels and opens calcium-dependent inwardly rectifying potassium channels, which results in hyperpolarization of neuronal membranes and a reduction in neuronal excitability, and subsequently, analgesia and sedation.

(Morphine Sulfate Sustained-Release Tablet, NCI Thesaurus)

In the central nervous and gastrointestinal systems, this agent has widespread effects including analgesia, anxiolysis, euphoria, sedation, respiratory depression, and gastrointestinal system smooth muscle contraction.

(Morphine sulfate, NCI Thesaurus)

The use of light at various frequencies to produce thermal analgesia and prevent damage to nerve and muscle tissue.

(Actinotherapy, NCI Thesaurus)

In the central nervous and gastrointestinal systems, this agent exhibits widespread effects including analgesia, anxiolysis, euphoria, sedation, respiratory depression, and gastrointestinal system smooth muscle contraction.

(Morphine, NCI Thesaurus)

Naloxone binds to opioid receptors in the CNS in a competitive manner, reversing or inhibiting characteristic opioid effects, including analgesia, euphoria, sedation, respiratory depression, miosis, bradycardia, and physical dependence.

(Naloxone Hydrochloride, NCI Thesaurus)

This leads to an inhibition of the typical actions of opioid analgesics, including analgesia, euphoria, sedation, respiratory depression, miosis, bradycardia, and physical dependence.

(Naltrexone, NCI Thesaurus)

The kappa opioid receptor plays a key role in the profound analgesia of opiates and is activated by the endogenous peptide ligand dynorphin, encoded by the prodynorphin gene.

(Pain Repression Pathway, NCI Thesaurus/BIOCARTA)

Pentazocine hydrochloride binds to and activates kappa- and sigma-opioid receptors, resulting in sedation and analgesia.

(Pentazocine Hydrochloride, NCI Thesaurus)
