1. The effects of DA2 agonist, quinpirole (50 micrograms/kg, i.v.) and a DA2 antagonist, domperidone (50 micrograms/kg, i.v.) on the release of adrenal catecholamines were evaluated in the anaesthetized and vagotomized dog. 2. Stimulations (5 V pulses of 2 ms duration for 3 min) of the splanchnic nerve at frequencies of 1, 3 and 5 Hz were applied randomly before and after injection of the drug. 3. The results show that quinpirole reduces significantly the release of adrenaline at 1 and 3 Hz but not at 5 Hz, while the release of noradrenaline is reduced at 1 Hz but not at 3 and 5 Hz. Inversely, domperidone potentiates significantly the release of both catecholamines at 3 and 5 Hz, but not at 1 Hz. 4. There was no change in basal release of adrenal catecholamines, adrenal blood flow or heart rate after both drug treatments. 5. The mean arterial pressure was not affected by domperidone treatment but there was a significant reduction in basal mean arterial pressure after the injection of quinpirole. 6. There was no change in any of these parameters during electrical stimulation. 7. Therefore, these results strongly suggest that DA2 dopamine receptors are present at the level of the adrenal medulla and that their activation could mediate an inhibitory modulation on the adrenal catecholamines release within a certain range of electrical stimulation.

The purpose of this clinical study was to determine the efficacy, tolerability, and impact on quality of life of domperidone--a specific peripherally acting dopamine antagonist--in the management of symptoms of gastroparesis, a common and potentially debilitating condition in patients with diabetes mellitus. In the first phase of this multicenter, two-phase withdrawal study, 287 diabetic patients with symptoms of gastroparesis of at least 6 months' duration received domperidone 20 mg QID in a single-masked fashion for 4 weeks. Efficacy was evaluated using a four-point rating scale (0 = none, 1 = mild, 2 = moderate, 3 = severe) for each of the following symptoms: nausea, abdominal distention/bloating, early satiety, vomiting, and abdominal pain. At the end of the first phase, patients with sufficient improvement in their total symptom score (a score < or = 6 and a decrease in score of > or = 5 units from the baseline [selection] visit) were eligible for the 4-week, randomized, placebo-controlled, double-masked withdrawal phase of the study. The impact of domperidone on quality of life was determined using the Medical Outcomes Study Short Form-36 (SF-36). Of 269 patients with data from the single-masked phase, 208 (77%) qualified for entry into the double-masked phase based on a statistically significant improvement in total symptom score, from a mean score of 10.32 at baseline (initial visit) to 3.79 after 4 weeks of single-masked domperidone therapy. During the double-masked phase, patients in the placebo group had significantly greater deterioration in total symptom scores compared with patients in the domperidone group (mean changes of 1.84 and 0.85, respectively). Similar significant differences in favor of domperidone were seen in the secondary efficacy variables (i.e., patients' diary scores and global assessments of symptoms). The tolerability profile of domperidone was similar to that of placebo. Patients who responded to domperidone experienced significant improvements in quality of life, as indicated by the SF-36 physical and mental component summary scores. During the double-masked phase, patients who were randomized to placebo experienced a significant deterioration in the physical component summary score compared with patients in the domperidone group. The results of this study suggest that domperidone 20 mg QID provides significant improvement in the upper gastrointestinal symptoms of diabetic gastroparesis and is well tolerated in patients with this condition.

We studied the receptor responsible for dopamine action in isolated perfused cortical collecting ducts (CCD) from rats treated with deoxy-corticosterone. (Critical experiments were repeated in CCD from untreated rats with the same results.) At doses > or = 1 microM, dopamine inhibited arginine vasopressin (AVP)-dependent Na+ and water transport (measured by the unidirectional lumen-to-bath 22Na+ flux and the transepithelial voltage) and osmotic water permeability (Pf). The effects of dopamine were not reversed by the dopamine-1 (D1) antagonist SCH-23390, and no inhibition was produced by the D1 agonists fenoldopam or SKF-81247. When Na+ transport and Pf were stimulated with 8-(4-chlorophenylthio)adenosine 3',5'-cyclic monophosphate plus 3-isobutyl-1-methylxanthine, dopamine did not inhibit, suggesting a "D2-type" receptor. However, the D2 agonist quinpirole had no effect on the AVP-dependent transepithelial voltage (VT), and the D2 and D3 antagonists domperidone and pimozide did not reverse dopamine inhibition of VT. The only agent tested that reversed the effects of dopamine was the D4-specific antagonist clozapine. We conclude that dopamine inhibition of salt and water transport in the CCD is mediated by a D4-like receptor.

This study used quantitative autoradiography to simultaneously evaluate the relative affinities of dopaminergic compounds for dopamine D2 and D3 receptors in rat brain. PD 152255, PD 128907, and l-nafadotride exhibited significantly higher affinity for cerebellar dopamine D3 sites than [3H]quinpirole-labeled sites in caudate/putamen (6.3-, 6.0-, and 2.3-fold, respectively). In contrast, chlorpromazine, risperidone, and domperidone were more potent at striatal dopamine D2 receptors (3.8-, 31-, and 40-fold, respectively). Dopamine, quinelorane, (+)-UH 232, and RS-trans-7-OH-PIPAT exhibited relatively little D2/D3 selectivity.

The availability of a sensitive and specific bioassay (BA) for PRL in human serum has made possible a comparative assessment of PRL bioactivity and immunoactivity in normal and abnormal serum specimens. Serum was studied from 20 normal subjects and 54 patients with a variety of disorders relating to PRL secretion. The correlation between the results of both assays was very close in all subjects. The mean BA/RIA ratio in normal subjects was 0.90, with a range from 0.67-1.33, and in patients with disordered PRL secretion the mean BA/RIA ratio was 0.94, with a range from 0.53-1.58. Similar results were obtained with PRL stimulatory testing using TRH, metoclopramide, and domperidone, and samples of culture medium from both PRL-secreting and non-PRL-secreting human pituitary tumor cultures. In one patient with a high proportion of "big, big" PRL and hyperprolactinaemia a BA/RIA ratio of 2.47 was found, a value well outside the normal range. However another patient with a similar history had a ratio of 0.82, in the range observed in normal subjects. These findings indicate that in a wide variety of clinical disorders the correlation between PRL bioactivity in the Nb2 system and immunoactivity in human serum samples is remarkably good under basal and stimulated conditions. One exception was found, but the nature of the underlying PRL abnormality in this patient remains to be investigated.

Dopamine (DA) causes a dose-dependent increase in the frequency of motor neuron bursts [virtual ventilation (fR)] produced by deafferented crab ventilatory pattern generators (CPGv). Domperidone, a D2-specific DA antagonist, by itself reversibly depresses fR and also blocks the stimulatory effects of DA. Serotonin (5HT) has no direct effects on this CPGv. Nicotine also causes dramatic dose-dependent increases in the frequency of motor bursts from the CPGv. The action is triphasic, beginning with an initial reversal of burst pattern typical of reversed-mode ventilation, followed by a 2- to 3-min period of depression and then a long period of elevated burst rate. Acetylcholine chloride (ACh) alone is ineffective, but in the presence of eserine is moderately stimulatory. The inhibitory effects of nicotine are only partially blocked by curare. The excitatory action of nicotine is blocked by prior perfusion of domperidone, but not by SKF-83566.HCl, a D1-specific DA antagonist. SKF-83566 had no effects on the ongoing pattern of firing. These observations support the hypothesis that dopaminergic pathways are involved in the maintenance of the CPGv rhythm and that the acceleratory effects of nicotine may involve release of DA either directly or via stimulation of atypical ACh receptors at intraganglionic sites.
The basal prolactin (PRL) levels on five different days, the PRL responses to thyrotropin-releasing hormone and to domperidone, and the thyroid-stimulating hormone (TSH) responses to domperidone were studied in 75 regularly menstruating women and 44 patients with moderate hyperprolactinemia. It was found that, for the entire sample, the responses to each of the stimuli could be described by a continuous function of the basal PRL levels. The present work provides evidence for the following conclusions: 1) The PRL responses to thyrotropin-releasing hormone and to domperidone merely bring additional diagnostic information relative to basal PRL levels in the occasional patients with macroprolactinemia; 2) there is a continuous spectrum of lactotroph activities in women, ranging from normal secretors through an intermediate group of hypersecretors (with progressively increased serum PRL levels and decreased responsiveness to stimuli) to full-blown prolactinomas; and 3) idiopathic hyperprolactinemia is a heterogeneous entity that includes the above intermediate group of patients, women with macroprolactinemia, and patients with undiagnosed prolactinomas.

Acute gastroenteritis (AGE) is a common condition among children that is frequently accompanied by vomiting. Symptomatic control of vomiting is important as it improves patient's general condition and reduces the need for intravenous therapy and hospitalization. Antiemetic agents including ondansetron and domperidone are used to provide symptomatic relief but the existing studies do not provide enough evidence of better efficacy for one over another.

Gastroparesis is a disorder of gastric emptying that occurs in the absence of mechanical obstruction. Its cardinal features include nausea, vomiting, bloating, early satiety and discomfort. Weight loss, dehydration, electrolyte disturbances and malnutrition may develop in severe cases. The majority of cases is idiopathic, long standing diabetes mellitus is responsible for about 25-30% of cases. Diabetic gastroparesis may render glucose control extremely difficult, its treatment represents a major challenge. Besides frequent, small meals and psychological support, several drug options are available, however, their efficacy is limited and only a few randomized studies have been performed to date. Prokinetic agents (erythromycin, domperidone, metoclopramide) and antiemetics (phenothiazines, serotonin antagonists, butyrophenones) are the most wide-spread medicaments. Among the novel, recently developed agents, 5-HT4 serotonin receptor agonists and dopamine D2 receptor antagonists are the most promising. Injection of botulinum toxin into the pyloric sphincter resulted in faster gastric emptying and symptom alleviation in some studies. Gastric electric stimulation appears to be one of the most effective options, both low and high-frequency stimulation may alleviate symptoms. Gastrostomy/jejunostomy and other surgical interventions are considered as "last resort".

Effects of the clathrate compound of mobenzoxamine (MBX) with beta-cyclodextrin (MBX-CD), a new gastro-intestinal function modulator, on the digestive system were studied in comparison with those of metoclopramide, domperidone and trimebutine. MBX-CD showed inhibitory effects that were approximately 1/4 times as potent as metoclopramide on both apomorphine- and copper sulfate-induced emesis and about 1/40 times as potent as domperidone on apomorphine-induced emesis in dogs. In rats, MBX-CD enhanced gastric emptying as potently as metoclopramide, and only MBX-CD showed a clear amelioration of the delayed gastric emptying induced by BaCl2. Similarly, only MBX-CD showed an ameliorative effect on small intestinal transport accelerated by BaCl2 in mice. Though both MBX and trimebutine inhibited spontaneous contractions of the isolated guinea pig stomach and rabbit intestine, it seemed that the properties of these effects were different from those of papaverine. On isolated guinea pig ileum, MBX inhibited contractions induced by various agonists equally to or more potently than trimebutine or papaverine. The results suggest that MBX-CD or MBX acts extensively on the gastro-intestinal system for the reason that it has not only the respective properties of the gastro-intestinal function modulators used as the standards, but also its own characteristic effects.
Administration of LY171555 (1 mg/kg i.v.) decreased mean arterial pressure (MAP) and heart rate in both pentobarbital- and urethane-anesthesized Sprague-Dawley rats. The depressor response to LY171555 in pentobarbital-anesthetized rats was sustained for at least 30 min, but in urethane-anesthetized rats lasted only approximately 3 min after LY171555 injection. In pentobarbital-anesthetized rats, pretreatment with domperidone (0.5 mg/kg) or metoclopramide (5 mg/kg) attenuated the depressor action of LY171555, whereas pretreatment with d(CH2)5Tyr(Me)arginine vasopressin (AVP) (10 micrograms/kg) only delayed the recovery phase of the depressor response to LY171555. In contrast, LY171555 administered to urethane-anesthetized rats after domperidone pretreatment induced a pressor response which was blocked completely by d(CH2)5Tyr(Me)AVP. Metoclopramide pretreatment in urethane-anesthetized rats prevented the decreases in MAP and heart rate induced by LY171555, whereas pretreatment with d(CH2)5Tyr(Me)AVP delayed the recovery phase of the depressor response. Pretreatment with d(CH2)5Tyr(Me)AVP per se decreased basal MAP in the urethane-anesthetized group, but not in pentobarbital-anesthetized rats. Basal plasma norepinephrine, epinephrine and AVP levels were higher in urethane-anesthetized rats than in the pentobarbital-anesthetized group. LY171555 administration decreased plasma norepinephrine without altering plasma epinephrine in both groups and induced a significant increase in plasma AVP which was greater in the urethane-anesthetized rats than in pentobarbital-anesthetized animals. These results suggest that LY171555 decreases MAP and heart rate in anesthetized rats by inhibiting norepinephrine release from nerve endings through the peripheral dopamine D2 receptor and that the time course of the depressor response may be altered by LY171555-induced AVP release, the magnitude of which appears to be dependent on the anesthetic agent.

Gastrointestinal involvement occurs in most patients with systemic sclerosis. Pathology is characterized by vasculopathy, resulting in tissue ischemia, progressive dysfunction and fibrosis. In its diffuse and visceral pattern, digestive manifestations may involve most of the intestinal tract and are the most frequent before renal, cardiac and pulmonary involvement. Whatever the visceral extension, about 80% of patients have digestive manifestations including gastroesophageal reflux, abnormalities of intestinal motility leading to chronic intestinal pseudo-obstruction and small bowel bacterial overgrowth and malnutrition. Long-term treatment of reflux with high-dose proton pump inhibitors appears safe and effective for symptom relief and may prevent recurrence of esophagitis and stricture. Prokinetic agents effective in pseudoobstruction include metoclopramide, domperidone, octreotide, and erythromycin.

A prospective randomised double blind crossover trial was conducted comparing the new synthetic cannabinoid nabilone with oral domperidone in a group of children receiving repeated identical courses of emetogenic chemotherapy for a variety of malignant diseases. Eighteen of 23 consecutive eligible children, aged 10 months to 17 years, completed the trial. When taking nabilone they experienced significantly fewer vomiting episodes and less nausea, and two thirds expressed a preference for the drug. The most common side effects of treatment with nabilone were somnolence and dizziness, with one patient being disturbed by hallucinations. The results indicate that nabilone is an effective antiemetic for children having chemotherapy, even for young children. It seems to be superior in this respect to domperidone, and although it has a higher incidence of side effects, these are mostly acceptable to patients. It can be recommended as an alternative to conventional antiemetic treatment throughout childhood.

Cytochrome P450 3A4 (CYP3A4) is the major enzyme responsible for phase I drug metabolism of many anticancer agents. It is also a major route for metabolism of many drugs used by patients to treat the symptoms caused by cancer and its treatment as well as their other illnesses, for example, cardiovascular disease. To assess the ability to inhibit CYP3A4 of drugs most commonly used by our patients during cancer therapy, we have made in silico predictions based on the crystal structures of CYP3A4. From this set of 33 common comedicated drugs, 10 were predicted to be inhibitors of CYP3A4, with the antidiarrheal drug loperamide predicted to be the most potent. There was significant correlation (r(2) = 0.75-0.66) between predicted affinity and our measured IC(50) values, and loperamide was confirmed as a potent inhibitor (IC(50) of 0.050 +/- 0.006 microM). Active site docking studies predicted an orientation of loperamide consistent with formation of the major (N-demethylated) metabolite, where it interacts with the phenylalanine cluster and Arg-212 and Glu-374; experimental evidence for the latter interaction comes from the approximately 12-fold increase in K(M) for loperamide observed for the Glu-374-Gln mutant. The commonly prescribed drugs loperamide, amitriptyline, diltiazem, domperidone, lansoprazole, omeprazole, and simvastatin were identified by our in silico and in vitro screens as relatively potent inhibitors of CYP3A4 that have the potential to interact with cytotoxic agents to cause adverse effects, highlighting the likelihood of drug-drug interactions affecting chemotherapy treatment.
