Recent studies have shown that endogenous serotonin is not required for colonic peristalsis in vitro, nor gastrointestinal (GI) transit in vivo. However, antagonists of 5-Hydroxytryptamine (5-HT) receptors can inhibit peristalsis and GI-transit in mammals, including humans. This raises the question of how these antagonists inhibit GI-motility and transit, if depletion of endogenous 5-HT does not cause any significant inhibitory changes to either GI-motility or transit? We investigated the mechanism by which 5-HT3 and 5-HT4 antagonists inhibit distension-evoked peristaltic contractions in guinea-pig distal colon. In control animals, repetitive peristaltic contractions of the circular muscle were evoked in response to fixed fecal pellet distension. Distension-evoked peristaltic contractions were unaffected in animals with mucosa and submucosal plexus removed, that were also treated with reserpine (to deplete neuronal 5-HT). In control animals, peristaltic contractions were blocked temporarily by ondansetron (1-10 μM) and SDZ-205-557 (1-10 μM) in many animals. Interestingly, after this temporary blockade, and whilst in the continued presence of these antagonists, peristaltic contractions recovered, with characteristics no different from controls. Surprisingly, similar effects were seen in mucosa-free preparations, which had no detectable 5-HT, as detected by mass spectrometry. In summary, distension-evoked peristaltic reflex contractions of the circular muscle layer of the guinea-pig colon can be inhibited temporarily, or permanently, in the same preparation by selective 5-HT3 and 5-HT4 antagonists, depending on the concentration of the antagonists applied. These effects also occur in preparations that lack any detectable 5-HT. We suggest caution should be exercised when interpreting the effects of 5-HT3 and 5-HT4 antagonists; and the role of endogenous 5-HT, in the generation of distension-evoked colonic peristalsis.

The aim of the present study was to investigate the participation of central 5-HT(3) receptors in the control of blood pressure and heart rate (HR) of non-stressed and stressed rats. The pharmacological stimulation of brain 5-HT(3) receptors by third ventricle injections of the selective 5-HT(3) receptor agonist m-CPBG induced a significant decrease in blood pressure in non-stressed rats and impaired the hypertensive response induced by restraint stress. The blockade of brain 5-HT(3) receptors by the central administration of the selective 5-HT(3) antagonist ondansetron elicited a significant increase in blood pressure in non-stressed rats. Conversely, the hypertensive response induced by restraint stress was not affected by central administration of ondansetron. Additionally, baroreflex-mediated bradycardia during phenylephrine-induced hypertensive response was preserved in non-stressed animals receiving third ventricle injections of m-CPBG, while the baroreflex-mediated tachycardia that occurs during the hypotensive response induced by the administration of sodium nitroprusside was impaired. It is concluded that the serotoninergic component represented by the brain 5-HT(3) receptors exerts a tonic inhibitory influence on the central control of blood pressure in non-stressed rats, probably by a sympathoinhibitory-related mechanism. On the other hand, during stress, this central 5-HT(3)-dependent inhibitory drive is overwhelmed by the different neurochemical systems that harmonically trigger and sustain the hypertensive response.

Two hundred forty-four adults were randomized to receive i.v. haloperidol 1 mg or ondansetron 4 mg, during general anesthesia. Nausea, vomiting, need for rescue, sedation, extrapyramidal effects, QTc intervals, and time to postanesthesia care unit discharge were evaluated with a third-party blind design.

The management of chemotherapy induced emesis presents a major difficulty in the paediatric population. Ondansetron is a 5-HT3 antagonist and its antiemetic properties have been established in adults receiving chemotherapy. Experience in the treatment of children, however, is limited. There is no standard comparative antiemetic in paediatric practice, so this European, multi-centred study aimed to assess the clinical efficacy and safety of ondansetron in a large cohort of children receiving a range of emetogenic chemotherapy regimens for malignant disease. Two hundred patients were entered into the study, of whom 183 fulfilled entry criteria. Forty per cent (10/25) of patients receiving cisplatin, 68% (27/40) receiving ifosfamide and 70% (83/118) receiving other drugs had less than 3 emetic episodes (vomit or retch) during their worst 24 hours of chemotherapy. The number of days without vomiting or retching during and shortly after receiving chemotherapy was also related to the emetic potential of the agents in the regimen: cisplatin 82/182 (45%), ifosfamide 137/213 (64%) and other agents 430/566 (76%). The control of nausea appeared better than that of emesis in each of the sub-groups analysed. Ondansetron was safe, well tolerated and effective in the prevention of vomiting in children receiving a wide variety of chemotherapy regimens.

Ondansetron was more effective with 45.3 POV-free patients (PFP) in an adjusted cohort of 100, while dimenhydrinate resulted in 38.2 PFP in an adjusted cohort of 100. The costs were significantly different between the two groups, CAD dollars 185.90 (+/-26.37, 95% CI, CAD dollars 173,89; CAD dollars 197.90) and CAD dollars 232.90 (+/-CAD dollars 66.84, 95% CI, CAD dollars 198.53; CAD dollars 267.27) per patient for ondansetron and dimenhydrinate, respectively. The length of stay in the postanesthetic care unit (PACU) represented over 97% of total costs, and the mean lengths of stay in the PACU for ondansetron and dimenhydrinate were significantly different, 3.43 and 4.41 h, respectively.

Ondansetron is a 5-hydroxytryptamine 3-receptor antagonist which has shown activity in the prevention of cytotoxic-induced emesis. Preliminary non-randomized studies also indicated efficacy in preventing sickness following radiotherapy. The present study was therefore undertaken to compare the efficacy and safety of ondansetron (8 mg tds orally) and metoclopramide (10 mg tds orally) in preventing sickness after single-exposure radiotherapy treatments of 8-10 Gy to the upper abdomen. Of 82 evaluable patients 38 received ondansetron and 44 metoclopramide. On the first day after irradiation vomiting or retching was prevented in all but one of the patients on ondansetron whereas metoclopramide achieved complete control of these symptoms in only 46% of subjects (P less than 0.001). Similarly nausea was significantly better controlled by ondansetron in the first 24 hours after treatment (P = 0.001). Complete or major control of vomiting or retching was maintained for 92%-100% of patients on ondansetron during the five days of the study period. In the metoclopramide group the proportion of patients with equivalent control improved from 70% on day 1 to 95 on day 5. Both drugs were well-tolerated.

An analytical method based upon liquid chromatography coupled to ion trap mass spectrometry (MS) detection with electrospray ionization interface has been developed for the simultaneous identification and quantification of droperidol and ondansetron in human plasma. The two drugs were isolated from 0.5 mL of plasma using a basic liquid-liquid extraction with diethyl ether/heptane (90/10, v/v) and tropisetron and haloperidol as internal standards, with satisfactory extraction recoveries. They were separated on a 5-μm C(18) Highpurity column (150 mm×2.1 mm I.D.) maintained at 30°C. The elution was achieved isocratically with a mobile phase of 2 mM HCOONH(4) pH 3.8 buffer/acetonitrile (60/40, v/v) at a flow rate of 200 μL/min. Data were collected either in full-scan MS mode at m/z 100-450 or in full-scan MS-MS mode, selecting the [M+H] (+) ion at m/z=294.0 for ondansetron, m/z=285.2 for tropisetron, m/z=380.0 for droperidol and m/z=376.0 for haloperidol. The most intense daughter ion of ondansetron (m/z=212.0) and droperidol (m/z=194.0) were used for quantification. Retention times for tropisetron, ondansetron, droperidol and haloperidol were 2.50, 2.61, 3.10 and 4.68 min, respectively. Calibration curves were linear for both compounds in the 0.50-500 ng/mL range. The limits of detection and quantification were 0.10 ng/mL and 0.50 ng/mL, respectively. The intra- and inter-assay precisions were lower than 6.4% and intra- and inter-assay recoveries were in the 97.6-101.9% range for the three 3, 30 and 300 ng/mL concentrations. This method allows simultaneous and rapid measurement of droperidol and ondansetron, which are frequently co-administrated for the prevention of postoperative nausea and vomiting.

All antiemetic trials in patients receiving chemotherapy that were published from January 2000 to July 2004 were evaluated. Standard prophylactic antiemetic therapy was derived from contemporary antiemetic guidelines published by oncology professional organizations and expert panels. The number of patients and studies in which patients received standard and substandard antiemetic therapy was determined for both the acute and delayed phases of chemotherapy-induced nausea and vomiting (CINV). Separate determinations were made for severely and moderately emetogenic chemotherapy. The annual percentage of studies in which substandard antiemetic prophylaxis was given and the percentage of patients who received substandard prophylaxis also were determined.

Effects of benzodiazepine (diazepam, lorazepam) and benzodiazepine-like anxiolytics (alpidem, suriclone) and a 5-HT-3 antagonist (ondansetron) on actual driving performance were measured in three double-blind, placebo-controlled studies. Subjects were healthy volunteers in two and anxious patients in the third. Treatments lasted for 8 days. Standardized testing occurred within the first full day and on the last day of treatment. No important differences existed between volunteers' and patients' baseline and/or placebo performances and both groups responded similarly to comparable drugs/doses. Benzodiazepine and benzodiazepine-like anxiolytics produced marked and pervasive driving impairment, which lasted throughout treatment; but ondansetron, none.

In a randomised, double-blind trial, we compared the use of ondansetron and droperidol for the prevention of nausea and vomiting after total abdominal hysterectomy, during patient-controlled analgesia with morphine. One hundred and forty-two patients were randomly allocated to one of two groups. All patients received a standardised general anaesthetic and postoperative analgesic regimen. One group received ondansetron 4 mg at induction of anaesthesia, and ondansetron 0.13 mg with each 1-mg bolus dose of morphine. The other group received droperidol 0.5 mg at induction and droperidol 0.05 mg per 1-mg bolus dose of morphine. Results were available for 137 patients. During the first 24 h after surgery, prophylaxis was successful in 26 of 66 patients given ondansetron (39%) compared with 36 of 71 patients given droperidol (51%). This difference was not statistically significant (Chi-squared = 1.766, p = 0.18). We conclude that in the regimens studied, ondansetron is not more effective than droperidol at preventing postoperative nausea and vomiting.

The complete effective rate and effective rate of prevention of nausea, vomiting, and anorexia during the periods 0 - 6 hours, 6 - 12 hours, 24 - 48 hours, and 48 - 62 hours after chemotherapy were similar in these 2 groups. However, these rates during the period 12 approximately 24 hours after chemotherapy were significantly higher in group A than in group B (all P < 0.05). The side effects of these 2 drugs included carebarja, headache, fatigue, etc, all being mild and not significantly different between these 2 groups.

We have performed a randomized, double-blind study comparing droperidol and high-dose ondansetron mixed with morphine for patient-controlled analgesia (PCA). To detect a reduction in the incidence of postoperative nausea and vomiting from 55% to 20% with a power of 80% at the P < 0.05 level, 29 patients per group were required. We studied 60 healthy women undergoing abdominal hysterectomy, anaesthetized using a standard technique. Group D received a bolus dose of droperidol 1.25 mg at induction followed by droperidol 0.1 mg per 1 mg of morphine from the PCA system. Group O received a bolus dose of ondansetron 4 mg at induction followed by ondansetron 0.32 mg per 1 mg of morphine. This dose of ondansetron is more than double that studied previously. Mean nausea and vomiting scores at 4, 8, 12 and 24 h, mean time to first vomit, sedation scores, incidence of side effects, and doses of prochlorperazine did not differ between the groups. In group D, 24 patients did not vomit compared with 23 in group O. The only significant difference between the groups was increased morphine consumption in the ondansetron group up until 12 h after operation (P < 0.05), but by 24 h this difference was not significant. The ondansetron regimen was more expensive (at local prices) by a factor of 27, and our results suggested no clinical advantage over droperidol.

A number of 5-HT3 receptor antagonists are currently in clinical development as antiemetics. In this paper we focus on two of these antagonists, granisetron and ondansetron, and compare their antimetic activity against cisplatin (10 mg/kg i.v.)- or whole body X-irradiation (200 rads)-induced emesis in the conscious ferret. The results presented here have been discussed in the light of the recently published literature. Our data suggest that in comparison to ondansetron, granisetron is a more potent, longer acting and pharmacologically "cleaner" compound with a more conventional dose-response profile. The possible impact of these features upon the performance of these compounds in the clinic is discussed particularly with respect to dosing regimens and clinical efficacy. Differences appear to be emerging between granisetron and ondansetron in both these respects, although a direct head-to-head clinical comparison has yet to be carried out. This would involve studies monitoring a sufficiently high number of patients receiving severely emetogenic regimes to allow real clinical differences to be detected with the appropriate statistical power.

The neurochemical consequences of aversive behavior based on novelty, rat social interaction, have been assessed in various rat brain regions utilizing high-performance liquid chromatography coupled with an electrochemical detector (HPLC-ECD) technique. The present studies indicated that compared to animals from the home cage, those exposed to the high-light aversive unfamiliar test condition, had significantly increased levels of 5-hydroxyindoleacetic acid (5-HIAA), the metabolite of 5-hydroxytryptamine (5-HT), in the tested brain regions including amygdala, entorhinal cortex, frontal cortex, temporal cortex, tuberculum olfactorium, hippocampus, nucleus accumbens, and striatum. The levels of 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), the metabolites of dopamine (DA), were increased in tuberculum olfactorium, nucleus accumbens, and striatum. When compared to the low-light familiar test condition (LF), the levels, following exposure to the highlight unfamiliar situation, of 5-HIAA were significantly increased in the amygdala, entorhinal cortex, tuberculum olfactorium, hippocampus, and nucleus accumbens, while the 5-HIAA levels remained unchanged in the frontal cortex, temporal cortex, and striatum. The DOPAC and HVA levels were also increased by the HU situation in the amygdala, tuberculum olfactorium, and nucleus accumbens. An increase was also found for the levels of DA in the amygdala. Such effects were prevented by diazepam or the 5-HT3 receptor antagonist ondansetron. It is concluded that the aversive test condition of the social interaction test (HU) increases 5-HT and DA turnover throughout the rat brain. Such effects might be related to the sensitivity to novel anxiolytic drug of the social interaction test.

Ondansetron combined with haloperidol produced a significantly greater improvement on PANSS overall scale and subscales for negative symptoms, general psychopathology, and cognition at endpoint compared to placebo with haloperidol, but no between-treatment group difference was observed on the subscale for positive symptoms and CGI-S. The ondansetron-treated group had a significantly higher proportion of patients with a 30% or greater baseline-to-endpoint reduction in PANSS total score than placebo. Patients in adjunctive ondansetron therapy also experienced significantly lower incidence and severity of parkinsonism and akathisia as well as fewer behavioral hyperactivity, cardiac, and gastrointestinal side effects.

It is a randomised cross-over multicenter study comparing the efficacy and the tolerance of granisetron (Gra) 1 mg and ondansetron (Ond) 8 mg, oral, given during two consecutive cycles to 188 naive patients scheduled to receive a moderately emetogenic chemotherapy. The antiemetic treatment is given one day per course, 1 hour before chemotherapy and the second administration from 8 to 12 hours after the beginning, during each of the two cycles; alternatively according to the randomisation. Five criteria are assessed; nausea (ordinal and visual analogic scales), emeric episodes (vomiting orland retching), complete response (minor or no nausea, no emetic episode and no rescue treatment), patient preference and tolerance. The intent to treat analysis showed no significant difference at cycle 1 between Gra and Ond; at cycle 2, there is no significant difference in the number of emetic episodes; for the prevention of nausea, the ordinal scale shows a significant difference (p = 0.028 in favour of Gra at day 1 (D1) but not from D2 to D5. Gra induced more complete response than Ond at D1 (p = 0.028), but not from D2 to D5. The cross-over study did not show any period or order effect, whereas a treatment effect on Ond was significant in favour of Gra (p = 0.01). There is no significant patients preference in favour of Gra or Ond. In conclusion, Gra was more efficient in preventing nausea and obtaining complete response on the first day of treatment, significantly at the second cycle. Both Gra and Ond had a good antiemetic activity for moderately emetogenic chemotherapy with complete response rates always over 50% on day 1; delayed emesis remain less weli controlled.
zofran drug classification
1. The influence of 5-hydroxytryptamine (5-HT) receptor agonists and antagonists on the emptying phase (circular muscle contraction) of the peristaltic reflex was investigated in the guinea-pig isolated ileum. 2. The effect of drug application to the serosal surface was measured as the changes in threshold pressure required to trigger the peristaltic reflex and the interval between the peristaltic strokes. A facilitation or inhibition of peristalsis was defined as a reduction or increase in threshold pressure respectively. 3. Peristalsis was not modified by the inclusion of methysergide (1 microM) and/or ondansetron (2 microM) in the bathing medium. 5-HT (0.1-1.0 microM) caused a facilitation of the peristaltic reflex; the response curve to 5-HT was not altered by the presence of methysergide (1 microM) and ondansetron (2 microM). 4. In the presence of methysergide (1 microM) plus ondansetron (2 microM), 5-HT (7.36 +/- 0.06), 5-methoxytryptamine (7.01 +/- 0.17), 5-carboxamidotryptamine (5.43 +/- 0.06), renzapride (6.09 +/- 0.17), (S)-zacopride (5.99 +/- 0.11), (R)-zacopride (5.61 +/- 0.13) and metoclopramide (4.8 +/- 0.65) caused a concentration-related facilitation of the peristaltic reflex, the pEC50 values (mean +/- s.e.mean) being shown in parentheses. 2-Methyl-5-HT was ineffective up to 10 microM. 5. The administration of SDZ 205-557 (1 microM) alone failed to modify the peristaltic reflex, but caused a parallel dextral shift in the concentration-effect curve to 5-HT (apparent pKB 7.38 +/- 0.30). It failed to modify the effect of acetylcholine to enhance the peristaltic reflex. 6. It is concluded that the rank order of potency of the 5-HT agonists from the indole and substituted benzamide series to facilitate the emptying phase of the peristaltic reflex in the guinea-pig ileum closely correlates with their published actions as 5-HT4 agonists in other systems. An agonist action on the 5-HT4 receptor is also supported by the potency of the 5-HT3/5-HT4 antagonist SDZ 205-557 (but not the 5-HT3 antagonist ondansetron) to inhibit the effects of 5-HT.

Formalin tests of rats treated with antidepressants and antagonists of monoamine receptors indicate that alpha(1) adrenoceptors, serotonin (5-HT)(2) receptors, and 5-HT(3) receptors are involved in antidepressant-induced antinociception, suggesting functional interactions between noradrenergic and serotonergic neurons as mechanisms of antidepressant-induced antinociception.
