| New Combination | NCT00236223 ↗ | The Effect of Gabapentin, Ketamine and Dexamethasone on Pain and Opioid Requirements After Hip Surgery | Terminated | Glostrup University Hospital, Copenhagen | Phase 4 | 2005-10-01 | Patients scheduled for primary hip replacement needs postoperative pain treatment, i.e. morphine. Morphine has side-effects: nausea, vomiting, sedation and dizziness. These side-effects are unpleasant for the patients and sometimes keeps them at bed longer time than needed. We investigate in new combinations of analgesics for postoperative pain, hoping to minimize the need for morphine. |
| New Formulation | NCT01275547 ↗ | The Analgesic Effect of Combined Treatment With Intranasal S-ketamine and Intranasal Midazolam | Completed | University Hospital, Basel, Switzerland | Phase 2/Phase 3 | 2011-01-01 | Introduction Ketamine is an old and generally well accepted analgesic used in the intra- and perioperative setting. Several studies demonstrated the effectiveness of ketamine in the postoperative setting. A new formulation of S-ketamine as an intranasal spray device was tested in our hospital in 8 healthy volunteers (unpublished data, EKBB 351/08). 20 mg of S-ketamine were administered intranasally and compared with S-ketamine i.v. and i.m.. None of the volunteers had serious adverse effects or complications. A preliminary data analysis shows a clear analgesic effect and good absorption of the intranasal S-ketamine. As a next step we would like to investigate the effect of S-ketamine intranasal spray combined with midazolam intranasal spray in a group of postoperative spinal surgery patients. The rational for the combination of intranasal S-ketamine and midazolam is the well known midazolam antagonising effect of ketamine induced psychomimetic adverse effects. Furthermore we know from other studies (EKBB 106/06) that midazolam intranasal spray has relaxant and anxiolytic effects. As far as we know, this is the first study which will examine the combination of S-ketamine and midazolam intranasal sprays in adult patients. Study work plan This prospective, randomized, double-blinded non inferiority study will address pain ratings and patient satisfaction in a postoperative setting in two treatment scenarios: 1. Alternating S-ketamine intranasal unit-dose spray (6 mg per dose) with midazolam intranasal spray (0.75 mg per dose) patient controlled application with a lock-out interval of 20 minutes between two applications and placebo patient controlled analgesia (PCA) with a lock-out interval of 12 minutes with saline 0.9% i.v. for 72 hours or until 40 unit-dose sprays are delivered 2. PCA with 2 mg morphine with a lock-out interval of 12 minutes i.v. with placebo intranasal spray (saline 0.9% + chitosan) with a minimum lock-out interval of 20 minutes for 72 hours or until 40 unit-dose sprays are delivered Patient number We will examine 36 patients, 18 patients in each group. The study duration for an individual patient will be at latest 72 hours, the total study duration is 4 to 5 months. Study importance An intranasal spray is an ideal application form for surgery patients, either in- or outpatients. On the other hand, ketamine and S-ketamine is quite often used in the perioperative setting as a rescue analgesic. In higher doses it could be used as an emergency tool in emergency prehospital medicine. In the perioperative setting it is important to evaluate the efficacy and safety of S-ketamine intranasal spray combined with midazolam intranasal spray in patients. If our study shows that S-ketamine intranasal spray is effective as an analgesic and has good patient acceptance, S-ketamine intranasal spay could be considered as an alternative, completely non-invasive analgesic procedure in a postoperative outpatient setting. As a consequence development of a nasal multidose-applicator combining S-ketamine and midazolam would be of interest. |
| New Combination | NCT03089905 ↗ | A Study to Compare the Long-term Outcomes After Two Different Anaesthetics | Recruiting | Baylor College of Medicine | Phase 3 | 2017-08-10 | There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function. |

| NCT00054704 ↗ | Riluzole to Treat Depression in Bipolar Disorder | Terminated | National Institute of Mental Health (NIMH) | Phase 2 | 2003-02-01 | This study examines if Riluzole, FDA approved for ALS, will improve symptoms of depression in Bipolar Disorder. Purpose: This study will examine the safety and effectiveness of riluzole (Rilutek trademark) for short-term treatment of depression symptoms, such as depressed mood, psychomotor retardation, and excessive sleeping in patients with bipolar disease. Riluzole is approved by the Food and Drug Administration (FDA) to treat amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's disease). Preliminary findings of a study using riluzole to treat acute depression in patients with unipolar depression indicate that it may have antidepressant properties in some patients. Patients between 18 and 70 years of age with bipolar I or II disorder without psychosis may be eligible for this 8-week study. Candidates must be currently depressed, must have had at least one previous major depressive episode, and must have failed to improve with prior treatment with at least one antidepressant. They will be screened with a medical history, physical examination, electrocardiogram (EKG), blood and urine tests, and psychiatric evaluation. A blood or urine sample will be analyzed for illegal drugs. Women of childbearing potential will have a pregnancy test. Participants will begin an 8-week course of treatment, starting with a placebo (a sugar pill formulated to look like the active drug) and, at some point, switching to riluzole. In addition to drug treatment, participants will undergo the following procedures: Physical examination and electrocardiogram (EKG) at the beginning and end of the study; Weekly check of vital signs (temperature, blood pressure and heart rate); Weekly 1-hour interviews consisting of psychiatric and psychomotor rating scales to assess treatment response; Weekly blood tests to measure blood levels of riluzole and evaluate drug side effects. At the end of the study, participants' psychiatric status will be reassessed and appropriate long-term psychiatric treatment arranged. Atendemos pacientes de habla hispana. We enroll eligible participants locally and from around the country. Travel arrangements are provided and costs covered by the National Institute of Mental Health (NIMH). (Arrangements vary by distance and by specific study.) After completing the study participants receive short-term follow-up care while transitioning back to a provider. |
| NCT00088699 ↗ | Rapid Antidepressant Effects of Ketamine in Major Depression | Completed | National Institute of Mental Health (NIMH) | Phase 1/Phase 2 | 2004-07-26 | Depressive disorders may be severe, chronic and often life-threatening illnesses. Impairment in physical and social functioning resulting from depression can be just as severe as other chronic medical illnesses. Recent preclinical and clinical studies suggest that the glutamatergic system is involved in the mechanism of action of antidepressants. This study examines whether ketamine can cause a rapid-next day antidepressant effect in patients with Major Depressive Disorder. This study was designed to address the questions: Does the NMDA antagonist ketamine produce rapid antidepressant effects in patients with treatment-resistant major depression? What are the neurobiological correlates of antidepressant response (examining multi-modal MRI, MEG, polysomnography and serum markers) Patients, ages 18 to 65 years with treatment-resistant major (unipolar) depression will in a double-blind crossover study receive either intravenous ketamine or saline solution. |
| NCT00115102 ↗ | Sensory Examination and Pharmacological Modulation of Oral Hyperexcitability in Patients With Atypical Odontalgia and Matched Healthy Controls | Completed | Danish Pain Research Center | Phase 4 | 2004-03-01 | This project examines experimental pain and chronic pain in the mouth, specifically the condition called atypical odontalgia (AO:atypical toothpain). In 16 patients with AO and 16 healthy persons, capsaicin (chili-pepper) is applied to the gingiva to cause pain. This pain is evaluated by the participants. In three sessions, 3 different medications are tested for effect on the pain. The medications are fentanyl, S-ketamine and placebo-treatment (saline). The aim is to know more about pain mechanisms in AO in order to develop an effective treatment. |
