Filter by:Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).
Muscle cramp is defined as a paroxysmal, involuntary, and painful contraction of skeletal muscle. Cirrhotic patients can encounter with muscle cramp frequently, which might be associated with poor quality of life. Gabapentin can be prescribed for muscle cramp. However, patients with liver cirrhosis have limited access to gabapentin which is metabolized primarily in liver. Pregabalin with a similar mechanism of action to gabapentin undergoes negligible metabolism owing to its improved pharmacokinetic properties. Thus, pregabalin might be a promising therapeutic option for patients with liver cirrhosis who are suffering from muscle cramp and susceptible to drug-induced hepatotoxicity. Therefore, the investigators hypothesize that pregabalin could effectively reduce painful symptoms derived from muscle cramp. In the current study, the investigators are going to evaluate the efficacy and safety of pregabalin by comparing outcomes between two groups (treatment group vs. placebo group).
The goal of this study is to evaluate the effectiveness of magnesium supplements (MagTabSR 168 mgs twice daily) for relief and/or improvement in the frequency, duration, and intensity of chronic leg cramps. Improvement in sleep disturbances and quality of life will also be evaluated.
Pelvic floor tension myalgia (PFTM) is increasingly noted in patients with chronic pelvic pain. Pelvic floor physical therapy is typically utilized and is at times combined with other therapies such as botox injections, trigger point injections or pudendal blocks. The investigators' study will randomize newly diagnosed patients with PFTM to weekly . Final patient assessment will be performed at 6 months to assess durability of response. Primary hypothesis: The addition of pudendal blocks to standard pelvic floor physical therapy will result in lower pain and pelvic floor muscle tension scores, lower baseline vaginal pressure and increase pelvic floor strength. Secondary hypothesis: The addition of pudendal blocks to standard pelvic floor physical therapy will result in a lower pain score in a shorter time frame, resulting in faster progress through physical therapy.
Many patients with ALS experience cramps during the course of the disease. Frequently, cramps occur as the first symptom of the disease, months before the patients notice weakness and wasting. Cramp severity varies from mild, without affecting daily activities and sleep, to disabling, where almost any voluntary muscle activity induces long standing, severely painful cramping. ALS patients who smoke herbal cannabis (marijuana) or drink hemp tea report lessening of cramps and fasciculations. Although, various medications, such as magnesium, quinine sulfate, lioresal, dantrolene, clonazepam, diphenylhydantoin and gabapentin are used for the treatment of cramps in ALS so far, no medication has been of proven benefit. However, a recent pilot study with THC in ALS showed symptomatic effects in "spasms", fasciculations, insomnia and appetite. The aim of the proposed study is to determine the tolerability, safety and efficacy of THC in the treatment of cramps in ALS. The hypothesis is that THC will lessen cramps in ALS.
1. Research question: Does vitamin D reduce the frequency and severity of nocturnal leg cramps in older persons who previously took quinine for leg cramps? 2. Experimental Design: This is a randomized, double blind, placebo controlled study of 70 men and women veterans receiving care at the Madison VA Medical Center(VAMC) or at the University of Wisconsin Hospitals and Clinics (UWHC). Individuals age 50 or more who have previously taken quinine for nocturnal leg cramps and meeting baseline criteria are eligible to enroll. Enrollees meeting laboratory criteria, including low-normal vitamin D levels, will undergo a 2-week "diary run-in" period to confirm cramp frequency. Those who report two or more leg cramps in each week will continue in the study and will be randomized to vitamin D or placebo. After a two-week wash-in, subjects will take a vitamin D capsule (50,000 units) once daily for 10 days, followed by a once weekly vitamin D (50,000 units) maintenance dose for 7 weeks. Subjects will record by diary the number and severity of leg cramps from the start of the "diary run-in" until a week after the last dose of study drug. Study investigators will call subjects at scheduled intervals to assess compliance, tolerability, and diary use. 3. Major risks to subjects: No major risks are anticipated. Excessive vitamin D can increase blood calcium levels (hypercalcemia), with symptoms such as thirst, nausea, and weakness. However, symptomatic hypercalcemia has not been reported except for those taking more than 40,000 units daily for several months. This is far above the cumulative dose in our study. 4. Potential benefits: Subjects may not receive any benefit. Vitamin D may alleviate leg cramps for subjects who receive it. 5. Consent Procedure: Flyers describing the study and telephone contact information will be mailed to patients who have received quinine during the period 2002-2007. The PI or Co-PI will return calls to describe the study and answer any questions. For persons meeting preliminary (pre-lab) study criteria, two copies of the consent form will be mailed, with the patient mailing back one signed consent to the PI.
Muscle cramps occur frequently among pregnant women, and few therapeutic options exist. This is a study of oral L-carnitine, a dietary supplement, for the treatment of muscle cramps in pregnancy. Our hypothesis is that carnitine will alleviate or eliminate muscle cramps experienced by pregnant women.
The study consists of cohorts where participants are randomized, in a 2:1 ratio, to 1 of 2 sequences, A and B. In each cohort, Sequence A, comprised of participants, who will receive ascending doses of ganaxolone and ascending doses of placebo. Sequence B, comprised of participants, who will receive ascending doses of placebo and ascending doses of ganaxolone. The dosing level in each subsequent cohort will be based upon experience gained from previous cohorts.
This study sets out to show whether infusions of magnesium can lessen the frequency of rest cramps and to determine whether rest cramp sufferers have a deficiency in magnesium.
The purpose of this study is to evaluate the efficacy of Eperisone HCl in the treatment of Acute Musculoskeletal spasm associated with Low-Back Pain.
