 Context examples 

Although the exact mechanism through which droperidol exerts its effects is unknown, droperidol may block dopamine receptors in the chemoreceptor trigger zone (CTZ), which may lead to its anti-emetic effect.

(Droperidol, NCI Thesaurus)

This agent may also stimulate the chemoreceptor trigger zone, thereby inducing nausea and vomiting.

(Nicotine, NCI Thesaurus)

Phenothiazines antagonize the dopamine D2-receptor in the chemoreceptor trigger zone (CTZ) of the brain, potentially preventing chemotherapy-induced emesis.

(Phenothiazine, NCI Thesaurus)

Perphenazine blocks postsynaptic dopamine 2(D2) receptors in the mesolimbic and medullary chemoreceptor trigger zone (CTZ), thereby preventing the excess of dopamine in the brain.

(Perphenazine, NCI Thesaurus)

This may prevent activation of the chemoreceptor trigger zone (CTZ) and may reduce nausea and vomiting.

(Buclizine, NCI Thesaurus)

Palonosetron competitively blocks the action of serotonin at 5-hydroxytryptamine type 3 (5-HT3) receptors located on vagal afferents in the chemoreceptor trigger zone (CTZ), resulting in suppression of chemotherapy-induced nausea and vomiting.

(Palonosetron hydrochloride, NCI Thesaurus)

A malignant neoplasm of the chemoreceptor system (e.g. carotid body, glomus jugulare, glomus vagale).

(Malignant Carotid Body Paraganglioma, NCI Thesaurus/CDISC)

In addition, apomorphine hydrochloride acts on the chemoreceptor trigger zone and is used as a central emetic in the treatment of drug overdose.

(Apomorphine Hydrochloride, NCI Thesaurus)

A benign neoplasm of the chemoreceptor system (e.g. carotid body, glomus jugulare, glomus vagale).

(Benign Carotid Body Paraganglioma, NCI Thesaurus/CDISC)

A small mass that is located in the inferior surface of the aortic arch. It functions as a peripheral chemoreceptor and is composed of glomus cells.
