New Formulation NCT00244777 ↗ Introduction of Hypo-osmolar ORS for Routine Use Completed United States Agency for International Development (USAID) Phase 4 2002-12-01 The World Health Organization has very recently recommended the routine use of a hypo-osmolar ORS in the management of diarrhoeal diseases. This recommendation is based on the better efficacy of the hypo-osmolar ORS over the standard WHO ORS demonstrated in controlled clinical trials. The recommendation, however, also expressed the need for "careful monitoring to better assess risk, if any, of symptomatic hyponatraemia". There thus is a need for phase IV trials before the new solution is introduced into routine clinical practice to assess the risk in relatively large number of patient populations. The proposed study will be carried out at two different settings- at the urban settings of the Dhaka Hospital (60000 patients) and at the rural settings of the Matlab Hospital (15000 patients) of ICDDR,B. The hypo-osmolar rice or glucose-based ORS will be introduced as standard management of patients with diarrhoea . The hypo-osmolar ORS will contain 75 mmol /L of sodium instead of 90 mmol/L. Surveillance will be carried out to detect adverse events focusing on the occurrence of seizures or undue lethargy during hospitalization. Each episode of seizure or undue lethargy would be evaluated to determine if they are associated with abnormal levels of serum sodium or glucose, or fever. It has been estimated that about 3% (1,800) of patients initially admitted to the Short Stay Ward of the Dhaka Hospital, and 340 patients at the Matlab Hospital might require admission to the longer stay inpatient wards due to seizure or altered consciousness. Such patients would be thoroughly assessed including determination of their serum sodium and glucose, two common causes of seizures/altered consciousness, to determine if and to what extent they could be attributed to hyponatraemia.The results from this study would be used in planning and implementing the routine use of the new formulation of ORS at all Government, NGO and private health care facilities that treat diarrhoeal patients, in Bangladesh and in other countries.

All Clinical Trials for Diazepam

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00004297 ↗ Phase III Randomized Study of Diazepam Vs Lorazepam Vs Placebo for Prehospital Treatment of Status Epilepticus Completed University of California, San Francisco Phase 3 1995-11-01 OBJECTIVES: I. Compare the efficacy, onset of clinical anticonvulsant activity, and complications of diazepam and lorazepam given intravenously as prehospital therapy to patients in status epilepticus. II. Determine the effect of prehospital therapy on the incidence of status epilepticus at the subsequent emergency department admission. III. Establish whether prehospital therapy alters hospital management of these patients and ultimately affects patient outcome.
NCT00004297 ↗ Phase III Randomized Study of Diazepam Vs Lorazepam Vs Placebo for Prehospital Treatment of Status Epilepticus Completed National Institute of Neurological Disorders and Stroke (NINDS) Phase 3 1995-11-01 OBJECTIVES: I. Compare the efficacy, onset of clinical anticonvulsant activity, and complications of diazepam and lorazepam given intravenously as prehospital therapy to patients in status epilepticus. II. Determine the effect of prehospital therapy on the incidence of status epilepticus at the subsequent emergency department admission. III. Establish whether prehospital therapy alters hospital management of these patients and ultimately affects patient outcome.
NCT00030004 ↗ Pilot Study of Spinal Manipulation for Chronic Neck Pain Terminated National Center for Complementary and Integrative Health (NCCIH) Phase 1 2000-05-01 This study is designed to determine whether a medicine that can produce temporary amnesia (midazolam) can be used to block the memory of treatment with spinal manipulation. This is important since any study that is designed to determine whether spinal manipulation is effective would be better if patients were not aware of whether or not they were treated. This would allow a true assessment of treatment effects without the complication of a strong placebo effect that manipulative treatment may produce.
NCT00106106 ↗ Acamprosate to Reduce Symptoms of Alcohol Withdrawal Completed National Institute on Alcohol Abuse and Alcoholism (NIAAA) Phase 2 2005-03-01 This study will examine whether a new drug called acamprosate can be helpful for alcohol withdrawal, a result of drinking high amounts of alcohol for long periods of time. Alcohol withdrawal can cause various symptoms, including nausea or vomiting, anxiety or depression, tremor, high blood pressure, and others. During withdrawal, brain chemicals called neurotransmitters change, with some rising to abnormally high levels. These changes may contribute to alcohol craving, drinking relapse and impaired mental performance. This study will see if taking acamprosate for 4 weeks can lower the levels of neurotransmitters, such as glutamate, lessen withdrawal symptoms and decrease alcohol craving and brain damage associated with withdrawal. Healthy normal volunteers and alcohol-dependent patients between 21 and 65 years of age may be eligible for this study. Participants are admitted to the hospital for 28 days. They receive standard inpatient care for alcohol detoxification, including a medical history and physical examination, neurological evaluation, laboratory tests, nursing, nutrition, discharge planning and referrals for treatment of concomitant conditions, if needed. In addition, they are randomly assigned to take either two acamprosate or two placebo pills three times a day for 28 days and undergo the following tests and procedures: - Days 1-28: Drug treatment. Patients take acamprosate or placebo daily. Patients with severe withdrawal symptoms may also receive diazepam (Valium). Throughout their hospitalization, patients fill out questionnaires about their emotional state and personality and are interviewed by staff about their mental health, use of alcohol, cigarettes, and illicit drugs, employment, support systems and family and social relationships, and their legal status. - Days 2 and 3: Blood tests. Blood is tested for levels of the stress hormones cortisol and ACTH, which are released to excess during alcohol withdrawal. For this test, a heparin lock (thin, flexible plastic tube with a rubber stopper on the end) is placed in an arm vein for blood collections each day at 6 AM, 12 noon, 6 PM and 12 midnight. Patients rest in bed for 30 minutes before each collection. - Day 4: Magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). These procedures are done at the same time. They use a strong magnetic field and radio waves to show structural and chemical changes in the brain. The patient lies on a table in a space enclosed by a metal cylinder (the scanner) for about 20 to 30 minutes during the test. - Day 5: Lumbar puncture (spinal tap). A local anesthetic is given to numb the area for the procedure. Then, a needle is inserted in the space between the bones in the lower back where the cerebrospinal fluid circulates below the spinal cord. A small amount of fluid is collected through the needle. - Days 5 and 6: Dexamethasone-corticotropin releasing factor (CRF) test. This test measures the effect of alcohol withdrawal on ACTH and cortisol. The patient takes a standard dose of the steroid dexamethasone at 11 PM on day 5. At noon the next day, they are given lunch and then stay in bed and rest. A plastic tube is put in an arm vein. A salt water solution is slowly infused through the catheter and a blood sample is withdrawn through it. At 3 p.m., the patient is given 100 micrograms of the hormone CRF. Repeated blood samples are obtained to measure ACTH and cortisol. - Days 23-27: All of the tests done on days 2-6 are repeated, except the MRI. MRS is repeated to measure neurotransmitters.
