To determine the contribution of metoclopramide to the efficacy of ondansetron in control of cisplatin-induced emesis, ondansetron was compared with ondansetron plus metoclopramide for antiemetic efficacy in a randomized double-blind trial. Enrolled 66 patients were treated with cisplatin(60mg/m2) in combination with etoposide, flourouracil, or vinblastine, and randomized to receive either onda...

This is an analysis of fetal outcome in pregnancies exposed to ondansetron to treat Hyperemesis Gravidarum (HG). In this retrospective cohort study, U.S. data on outcome were collected on 1070 pregnancies exposed to ondansetron and compared to outcomes in two control groups: 771 pregnancies in women with a history of HG with no ondansetron exposure and 1555 pregnancies with neither a history of...

BACKGROUND Postoperative pruritus, nausea, and vomiting are common side effects of intrathecal or epidural opioids. Intravenous ondansetron has been used for postoperative emesis. However, there are no reports regarding epidural ondansetron. Two studies were conducted to evaluate the prophylactic effects of epidural ondansetron for opioid-induced pruritus, nausea, and vomiting. METHODS Neurot...

This study aimed to attain a comparison in pharmacokinetic parameters of ondansetron after transdermal (as invasomes gel) and oral solution) routes. Ondansetron is 5 ? hydroxytryptamine receptor antagonist used for chemotherapy radiotherapy induced nausea emesis. The was performed using Wistar albino rats weighing 200 ±20 g divided into two groups (6 each). A dose 0.28 mg ondansetron, eq...

5-Hydroxytryptamine (5-HT) causes antinociception via presynaptic 5-HT3 (5-HT subtype 3) receptors on primary afferent nociceptive neurones in the spinal cord dorsal horn. Therefore, ondansetron (a 5-HT3 receptor antagonist) may increase the perception of a noxious stimulus or decrease the effects of concurrently administered antinociceptive drugs. Using a randomized, double-blind, crossover st...

UNLABELLED We assessed the efficacy and safety of ondansetron (0.1 mg/kg IV) prophylactically administered before surgery for prevention of postoperative vomiting (POV) in a double-blind, placebo-controlled study of 670 pediatric patients, 1- to 24-mo-old, undergoing elective surgery under general anesthesia. The study enrolled 335 children in each treatment group (ondansetron versus placebo). ...

Background: Nausea and vomiting is one of the most common complications after the strabismus surgery. In this study, we evaluated the efficacy of atropine versus ondansetron administration on the incidence of postoperative nausea and vomiting and duration of recovery stay in patients undergoing this procedure. Methods: In this case-control study, 90 patients between 3 to 30 years old who were ...

In this randomized study we compared the efficacy of ondansetron 4 mg with ondansetron 8 mg for the prevention of postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy with sevoflurane and remifentanil infusion anaesthesia. Sixty patients were randomized to receive ondansetron 8 mg (30 pts) or ondansetron 4 mg (30 pts) before the induction of anaesthesia with thiopental an...

OBJECTIVE To compare the efficacy of ondansetron alone and combination of ondansetron and dexamethasone in preventing post-operative nausea and vomiting in patients undergoing laparoscopic cholecystectomy. METHODS The randomised control trial was conducted from April 23 to August 22, 2009, at the Liaquat National Hospital, Karachi, and comprised 100 American Society of Anaesthesiology I and I...

Droperidol and ondansetron are potent anti-emetic agents which are often administered together. Although both drugs prolong QT interval in man by inhibition of Human Ether-a-go-go Related Gene-coded potassium channels, only droperidol was tested using more integrated experimental models. Therefore, we studied the effects of both compounds and their combination on action potentials (AP) of rabbi...
