Ondansetron is a serotonin (5HT3) receptor antagonist used for the prevention and treatment of postoperative nausea vomiting. It available in many dosage forms market. Various analytical methods determination have been studied this review article such as UV spectroscopy, mass high-performance liquid chromatography, thin layer new electrospray ionization spectrometry etc. human plasma can be est...

BACKGROUND This study examined whether different ondansetron dosing schedules plus dexamethasone influenced antiemetic efficacy during multiple cycles of cisplatin-based chemotherapy (CT). Antiemetic activities between previous CT and subsequent cycles were compared. METHODS The cross-over study involved 424 patients. Arm A, three doses of 8 mg ondansetron given intravenously (IV) at 4-hourly...

BACKGROUND Negative symptoms and cognitive deficits are two partially-related features of schizophrenia which have a major negative impact on social function and objective quality of life. Standard drug treatments have little impact on either. There is some evidence that anti-inflammatory treatment may have beneficial effects in schizophrenia and major depression. Statins are cholesterol-loweri...

Serotonin type 3 (5-HT(3)) receptors have been shown to participate in the negative-feedback control of food intake. We previously reported that cholecystokinin (CCK)-induced suppression of food intake is partly mediated through 5-HT(3) receptors when rats were tested on a preferred liquid diet, but whether such an effect occurs when they are tested on a solid maintenance diet is unknown. In th...

BACKGROUND Given the potential role of the 5-hydroxytryptamine-3 receptor in the pathogenesis of schizophrenia, this study was performed to determine whether ondansetron plus risperidone could reduce the negative and depressive symptoms in patients with treatment-resistant schizophrenia. METHODS In a double-blinded, placebo-controlled, randomized trial (IRCT registration # 201112125280N7), in...

BACKGROUND Accumulating data support the involvement of the serotonin (5-hydroxytryptamine [5-HT]) system in the pathophysiology of chronic fatigue syndrome. Neuropharmacologic studies point to a hyperactive 5-HT system, and open-label treatment studies with 5-HT(3) receptor antagonists have shown promising results. In this randomized controlled clinical trial, the effect of ondansetron, a 5-HT...

Topal A. , M. Kaya, N. Gül: Ondansetron and Granisetron in the Prophylaxis of Nausea and Emesis Induced by Cisplatin in Dogs. Acta Vet. Brno 2005, 74: 111-116. In the present study, the effects of 5-HT3 receptor antagonist granisetron and ondansetron on the acute phase of cisplatin-induced nausea and emesis were analyzed in dogs. Fifteen healty dogs were used in this study. Cisplatin was admini...

Ondansetron is widely used in general practice for nausea and vomiting due to any cause. We report a rare side effect, life-threatening hypokalaemia following intravenous Ondansetron injection. It may be judicious to restrict the use of Odansetron to patients with severe vomiting due to chemotherapy or in post-operative state. Life-threatening hypokalemia can occur without any warning and may b...

We investigated whether the 2677G>T/A and 3435C>T polymorphisms of adenosine triphosphate-binding cassette subfamily B member 1 (ABCB1) affect the efficacy of ondansetron to prevent postoperative nausea and vomiting. One hundred and ninety-eight patients undergoing general anaesthesia were enrolled. Thirty minutes before the end of surgery, 0.1 mg.kg⁻¹ ondansetron was administered intravenously...
