Modulation by 5-HT3 and 5-HT4 receptors of the release of 5-hydroxytryptamine from the guinea-pig small intestine.

1993

The effects of agonists and antagonists of 5-hydroxytryptamine (5-HT) receptors on the release of endogenous 5-HT from enterochromaffin cells were studied in the vascularly perfused isolated guinea-pig small intestine. The experiments were done in the presence of tetrodotoxin in order to exclude a neuronally mediated influence on 5-HT release. The 5-HT3 receptor agonist 2-methyl-5-HT increased 5-HT release, and this effect was antagonized by 1 nmol/l tropisetron. Nanomolar concentrations of tropisetron, MDL 72,222 and granisetron decreased 5-HT release. Ondansetron (0.1 and 1 mumol/l) did not modify 5-HT release. 5-Methoxytryptamine, BIMU8 and cisapride concentration-dependently inhibited 5…

A two-centre prospective randomized open cross-over study to compare granisetron (Gra) vs ondansetron (Ond) vs tropisetron (Tro) in the prevention of high-dose cisplatin-induced nausea and vomiting was carried out. The notable characteristics of our study were: all patients were very homogeneous for tumor site (head and neck cancer), all were treated with high-dose (80 to 100 mg/sqm) cisplatin on day 1 and all were chemotherapy-naive. 141 patients for a total number of 541 chemotherapy cycles containing high-dose cisplatin were randomized to receive 24 mg of Ond intravenously (i.v.) or 3 mg of Gra i.v. or 5 mg of Tro i.v. for the control of acute nausea and emesis. In the Gra group in 138 o…
