43 Clinical Trials for Various Conditions
The investigators hypothesis is that obstructive sleep apnea (OSA) patients with a low arousal threshold may wake up too early during a respiratory event, before upper airway muscles can be activated to achieve stable ventilation. Thus, strategies to manipulate the respiratory arousal threshold could potentially improve the quality of sleep and sleep disordered breathing. Agents that raise arousal threshold are therefore likely to benefit some patients with OSA. The overall goal of this project is to determine the importance of the arousal threshold in OSA, determine which patients might benefit from a raised arousal threshold, and test this hypothesis by using pharmacological manipulation of the arousal threshold to achieve this goal.
The purpose of the study is to determine whether a significant and predictable change in bioavailability of extended-release venlafaxine occurs following Roux-en-Y gastric bypass.
Purpose: The purpose of this study is to demonstrate the potential efficacy of venlafaxine administration in reducing acute and chronic musculoskeletal pain in individuals presenting to the ED for evaluation after motor vehicle collision. Participants: Participants will consist of 60 patients between the ages of 18-50 who present to the ED within 12 hours post-motor vehicle collision. Patients who report a neck pain score \> 6 will be screened for further eligibility. Procedures (methods): Using a placebo-controlled, randomized, double-blind trial design, 60 high risk patients will be randomized to venlafaxine vs. placebo in the ED. The ability of venlafaxine to decrease acute and persistent musculoskeletal neck pain will be assessed during serial short-term telephone follow-ups as well as more in-depth follow-ups at 6 weeks, 4 months, and 6 months post-MVC.
The primary objective of this study is to determine the efficacy of both low-dose oral (by mouth) 17-ß-estradiol and the non-hormonal drug venlafaxine XR compared to placebo in reducing hot flashes. Included in this objective is the intention to compare venlafaxine XR to estradiol therapy, to provide evidence of the relative efficacy of venlafaxine to what is currently considered the most established but also a controversial therapy. 17-ß-estradiol is a type of estrogen. Venlafaxine XR is the extended release (XR) version of venlafaxine. Venlafaxine XR is an serotonin-norepinephrine reuptake inhibitor (SNRI). A placebo is a substance containing no medication.
Study evaluates the drug-drug interaction between Ticagrelor and Venlafaxine when taken together in healthy volunteers
The purpose of this study is to determine if Venlafaxine Extended Release (Ven-XR) is effective in treating individuals with marijuana addiction and depression.
Patients experience pain after their knee replacement surgery - and some may continue to experience persistent pain long after their knee replacement surgery. Traditional pain management strategies reply on pain medication such as opioids for pain control. However, these drugs do not work well for pain associated with movement or the the nerve pain (tingling, electrical sensations) after surgery. In addition, opioids are associated with significant side effects such as nausea, vomiting, respiratory depression, depression, cognitive dysfunction and risk of persistent opioid use. Neuropathic pain medications, such as venlafaxine are effective in managing nerve pain. Recent studies also support its potential role in acute pain management. Here, we propose a prospective randomized clinical trial 1) to evaluate the efficacy of Venlafaxine in reducing pain intensity and opioid consumption at post-operative day 1 (POD1) and 1- week after surgery, and 2) to examine whether the use of Venlafaxine will reduce the incidents of chronic postsurgical pain in TKA patients at 3-month time point.
This trial studies how well gabapentin, methadone, and oxycodone with or without venlafaxine hydrochloride work in managing pain in participants with stage II-IV squamous cell head and neck cancer undergoing chemoradiation therapy. Gabapentin may reduce the need for these pain medications if given at the start of radiation therapy. Methadone and oxycodone may help relieve pain caused by cancer. Venlafaxine hydrochloride may prevent or improve pain caused by cancer. It is now yet known whether giving gabapentin, methadone, and oxycodone with venlafaxine hydrochloride will work better in managing pain in participants with squamous cell head and neck cancer undergoing chemoradiation therapy.
This study is being conducted to evaluate how the body absorbs and processes the immediate release (IR) and sustained release (XR) medication venlafaxine (Effexor®). Subject who are 1-3 years post gastric bypass or sleeve gastrectomy surgery will be invited to participate. Non-surgical controls will also be enrolled based on a matching criteria to post gastric bypass subjects. Participants will be asked to complete two 12-hour study days approximately 11 days apart. This study will enroll up to 30 participants.
You are being asked to take part in this research study because you are going to be treated with oxaliplatin chemotherapy as part of your standard care. Oxaliplatin commonly causes neuropathy (numbing, tingling and/or pain).The purpose of this study is to compare the effects, good and/or bad, of venlafaxine with a placebo (an inactive agent) on oxaliplatin-induced neuropathy (numbing, tingling and/or pain)
This study will test the use of venlafaxine to treat the depression in Alzheimer's Disease. Venlafaxine works by increasing natural substances in the brain (serotonin and norepinephrine) that help maintain mental balance. Alzheimer's disease (AD) is the commonest neurodegenerative disease of aging and the cause of major financial and emotional burden to patients, families and caregivers, and society. Depression is a very common symptom of AD, affecting as many as 50% of patients over their illness. Depression in AD (Alzheimer's disease) contributes greatly to patient disability and caregiver distress. Neither psychosocial interventions nor psychotropic medications have proven effective to date for the treatment of depression in AD.Venlafaxine is approved by the U.S. Food and Drug Administration (FDA) for the treatment of major depression but it is not known whether or not it can help depression in Alzheimer's Disease.
The purpose of this study is to assess the change in quality of life over a 6 month period between gabapentin and venlafaxine in men with prostate cancer treated for hot flashes related to androgen deprivation therapy.
This study will examine the effects of co-administration of SPD489 and the antidepressant EFFEXOR XR on the pharmacokinetics of lisdexamfetamine, d-amphetamine, and EFFEXOR XR. In addition, serial blood pressure and pulse measures will be obtained and examined to ensure that there are no unexpected changes in vital signs following co administration of SPD489 and EFFEXOR XR that would impact the further study of this drug combination. The hypothesis is that a drug drug interaction could possibly exist.
Rationale: Venlafaxine may help relieve hot flashes in women who have had breast cancer. Hypnosis or focused attention may help control hot flashes in postmenopausal women. It is not yet known whether giving venlafaxine together with hypnosis or focused attention is more effective in treating hot flashes. Purpose: This randomized clinical trial is studying venlafaxine together with hypnosis or focused attention in treating patients with hot flashes.
This is a study to determine the percentage of patients with depression who are treated with extended-release venlafaxine HCl (U.S. marketed brand Effexor XR®) who are Poor Metabolizers (based on the levels of the drug in the blood) at 2D6 (a system in the liver that breaks down some medications and other chemicals).
The purpose of this study is to determine if the relative difference in Pharmacokinetics (PK) between extensive metabolizers (EMs) and poor metabolizers (PMs) is the same with desvenlafaxine SR and venlafaxine ER when a single dose is administered.
RATIONALE: Studying samples of blood in the laboratory from patients receiving tamoxifen may help doctors learn more about the effects of other drugs on the level of tamoxifen in the blood. PURPOSE: This clinical trial is studying levels of tamoxifen in the blood of women with breast cancer and in women at high risk of breast cancer who are receiving tamoxifen together with venlafaxine, citalopram, escitalopram, gabapentin, or sertraline.
The purpose of this study is to evaluate the effect of the Dialogues Time to Talk program in subjects treated with Venlafaxine Extended Release (ER). Dialogues Time to Talk Program is a patient management program, which aims to help patients achieve successful outcomes by reinforcing physician treatment efforts, providing feedback to treating physicians, and encouraging better physician-patient communications.
The purpose of this study is to determine if the relative difference in PK between extensive metabolizers (EMs) and poor metabolizers (PMs) is the same with desvenlafaxine SR and venlafaxine ER when a single dose is administered.
Preliminary research has shown that venlafaxine, a medication currently used for treating depression, may also discourage cocaine use in depressed individuals. This study will evaluate the effectiveness of venlafaxine in reducing cocaine use and alleviating depression in individuals addicted to cocaine.
The purpose of this study is to evaluate Venlafaxine as a treatment option for hot flashes in breast cancer survivors. The goals of this study are to assess the effectiveness and toxicity of venlafaxine hydrochloride and identify the psychological, behavioral, and physical outcomes associated with relief of hot flashes in women following treatment for breast cancer.
The primary purpose of this study is to examine whether IV hydrocortisone can speed up the time required for Venlafaxine XR to work.
This study will assess the effectiveness of venlafaxine XR, randomized to either venlafaxine XR or placebo in preventing the relapse of generalized anxiety disorder after 6 months of treatment versus 12 months of treatment.
This is a randomized, double-blind, active control, 8-week, flexible dose study of sertraline vs. venlafaxine Extended Release in the acute treatment of Major Depression in male and female outpatient sites that will recruit 15-20 patients each. Subjects will be randomized in a 1:1 ratio to receive either sertraline or venlafaxine XR based on a computer-generated randomized list.
This research study is to evaluate the safety and usefulness of venlafaxine-XR in the treatment of major depression in the elderly.
The purpose of this study is to evaluate the pain-relieving effects of venlafaxine hydrochloride (Effexor) in chronic neuropathic (burning, shock-like, electric) pain after spinal cord injury (SCI). Although a number of medications have been used to treat SCI pain, no drug has been consistently helpful, and, therefore, many people with SCI continue to have difficult chronic pain. Venlafaxine is a new anti-depressant drug that has not been tested for use in SCI neuropathic pain, but has been helpful for other types of neuropathic pain.
RATIONALE: Venlafaxine may be effective in relieving hot flashes caused by hormone therapy. Giving venlafaxine with zolpidem (a sleeping pill) may improve sleep and quality of life in women who are receiving hormone therapy for treatment or prevention of breast cancer. PURPOSE: This randomized clinical trial is studying giving venlafaxine together with zolpidem to see how well it works compared to venlafaxine alone in relieving hot flashes and associated sleep disorders in women who are receiving hormone therapy to treat or prevent breast cancer.
RATIONALE: Medroxyprogesterone and venlafaxine may be effective in relieving hot flashes. It is not yet known whether venlafaxine is more effective than medroxyprogesterone in relieving hot flashes. PURPOSE: Randomized phase III trial to compare the effectiveness of medroxyprogesterone with that of venlafaxine in treating women who are experiencing hot flashes.
Cancer and depression commonly occur together, and each worsens the other. We conducted a large psychotherapy study treating depression in breast cancer patients, showing that psychotherapy lowers symptoms. Surprisingly, no studies have compared depression-focused psychotherapy to antidepressant medication for patients with breast cancer and depression. We applied to the National Cancer Institute for a large, cross-national grant. Reviewers asked us to first demonstrate that patients would accept either psychotherapy or medication as treatment. Thanks to funding from the Columbia Herbert Irving Cancer Center, we will test this study approach. We will randomly assign 20 patients with both non-metastatic breast cancer and major depression to 12 weeks of tele-therapy (by Zoom) with either interpersonal psychotherapy or a serotonin reuptake inhibitor. We expect patients in both treatments to report improvement in depression symptoms. We will also measure C-reactive protein, a blood test of inflammation elevated in both cancer and depression, which may predict medication response.
This is an investigator-initiated study comparing two types of FDA-approved anti-depressants, Escitalopram and Venlafaxine, to placebo, in order to determine if these medications have positive effects on cognition and memory in those who are between the ages of 50 to 89 years old, who are cognitively normal, and who have subjective memory concerns. Research has shown that those who are cognitively normal but report subjective cognitive impairment are more likely to progress to mild cognitive impairment and Alzheimer's disease in the future. Anti-depressants such as Escitalopram and Venlafaxine have been shown to stimulate production of neurons in memory-sensitive areas such as the hippocampus. Therefore, the investigator is researching whether these drugs would help cognition in those with subjective cognitive impairment, and would help to prevent cognitive decline and eventual Alzheimer's disease.
