| OTC | NCT00055549 ↗ | Dextromethorphan to Treat Patients With Voice Spasms | Completed | National Institute of Neurological Disorders and Stroke (NINDS) | Phase 1 | 2003-03-04 | This study will examine how dextromethorphan, a drug that alters reflexes of the larynx (voice box), might change voice symptoms in people with voice disorders due to uncontrolled laryngeal muscle spasms. These include abductor spasmodic dysphonia (breathy voice breaks), adductor spasmodic dysphonia (vowel breaks), muscular tension dysphonia (tight strained voice), and vocal tremor (tremulous voice). Dextromethorphan-one of a group of drugs called NMDA antagonists-has been used for years in over-the-counter cough suppressant medicines. In animal studies, the drug has blocked one of the reflexes in the larynx that may be associated with spasms in the laryngeal muscles. This study will compare the effects of dextromethorphan, lorazepam (a valium-type drug), and a placebo (inactive substance) in patients with the four types of voice disorders described above. Patients with spasmodic dysphonia, muscular tension dysphonia and vocal tremor may be eligible for this study. Individuals who smoke or use tobacco, who have vocal nodules or polyps, or who have a history of airway obstruction may not participate. Candidates will be screened with a medical history and physical examination, a questionnaire, voice recording (repeating sentences into a microphone), and nasolaryngoscopy (examination of the larynx with a tube advanced through the nose). For the nasolaryngoscopy, the inside of the nose is sprayed with a decongestant (to open the nasal passages) and possibly a local anesthetic. A small, flexible tube called a nasolaryngoscope is passed through the nose to look at the larynx during speech and other tasks, such as singing, whistling and prolonged vowels. Participants will be admitted to the NIH Clinical Center for each of three visits, which will last from the afternoon of one day to late afternoon of the following day. At each visit, patients will complete a questionnaire, baseline speech recording, and a test for sedation level. They will take three pills-either dextromethorphan, lorazepam, or placebo-one every 6 hours. Vital signs will be checked every 6 hours and the level of sedation during waking hours will be monitored. One to three hours after taking the third pill, speech recording, questionnaire and test of sedation will be repeated to check for possible voice changes. Patients will be given a different pill at each visit. ... |

| NCT00000441 ↗ | Drug Therapy for Alcohol Detoxification | Completed | National Institute on Alcohol Abuse and Alcoholism (NIAAA) | Phase 4 | 1969-12-31 | This project will provide relevant clinical information for primary care practitioners treating alcohol withdrawal syndrome in outpatient settings. This double-blind, placebo- controlled clinical trial will compare the effectiveness of lorazepam (Ativan) and carbamazepine (Tegretol) in alcoholics who meet the criteria for a diagnosis of uncomplicated alcohol withdrawal syndrome. Participants are randomized to five days of treatment with a 1-week posttreatment followup. |
| NCT00001725 ↗ | Studies of Dextromethorphan and Topiramate to Treat Oral and Facial Pain | Completed | National Institute of Dental and Craniofacial Research (NIDCR) | Phase 2 | 1997-12-01 | This study will evaluate the safety and effectiveness of two drugs-dextromethorphan and topiramate-in treating orofacial (mouth and face) pain. Dextromethorphan, a commonly used cough suppressant, and topiramate, an anti-seizure medicine, block certain receptors on brain and spinal nerve cells that may cause the cells to produce electrical discharges and pain. Patients 18 years of age and older with oral and facial pain with trigeminal nerve damage and who have had pain daily for at least 3 months may be eligible for this study. Candidates will be screened with a medical history, physical examination, blood tests and psychiatric evaluation. These results will serve as baseline values for participants. Those enrolled in the study will take either dextromethorphan or topiramate in a 2-part study as follows: Dextromethorphan In Part 1, patients will take dextromethorphan and lorazepam (a commonly used anti-anxiety drug) separately in two 6-week periods. (Lorazepam is used in this study as an "active placebo" for comparison with dextromethorphan. An active placebo is a drug that does not work for the problem being studied but whose side effects are like those of the test drug.) They will take dextromethorphan for 4 weeks to determine the maximum tolerated dose (the highest dose that does not cause troubling side effects) and will stay on that dose for the remaining 2 weeks. Then they will repeat this process with lorazepam. Patients who respond to either drug may continue with Part 2 of the study, which compares these two drugs four more times to confirm the response seen in Part 1. In Part 2, the maximum tolerated dose will be determined in a 2-week period and that dose will be continued for another 2 weeks. This procedure will be repeated eight times. Throughout the study, patients will keep a daily pain diary. They will be contacted by telephone 2 to 3 times a week during dose escalation to check for side effects. At the end of each of the two 6-week periods in Part 1 and at the end of each 4-week period in Part 2 of the study, patients will have a 1-hour clinic visit. Participants who live more than a few hours' drive from NIH will have a full telephone follow-up evaluation instead of the clinic visits. Topiramate Patients who receive topiramate will follow a plan similar to that described above for dextromethorphan, with the following exceptions. They will take topiramate and an inactive placebo (a look-alike pill that has no active ingredients) in two separate 12-week periods. Patients' maximum tolerated dose will be determined in the first 8 weeks and they will stay on that dose for the remaining 4 weeks of each period. Patients who respond to the medication in Part 1 may continue with Part 2 to confirm the response. Part 2 consists of six 6-week periods. The first 4 weeks of each will be used to determine the maximum tolerated dose and the patient will remain on that dose for the next 2 weeks. Patients will keep a daily pain diary and will be contacted by phone 2 to 3 times a week while doses are being increased. Patients who complete Part 2 of the topiramate study may participate in another phase of the study that will last for 2 years. Those who continue for this phase will take topiramate for the 2-year period. They will be followed regularly by a study nurse and will come to NIH every 6 months for a follow-up visit. |
| 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. |
