Gabapentin + Tizanidine for Insomnia in Chronic Pain
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests gabapentin and tizanidine, two pain-relief medications, to determine their effectiveness for people with chronic pain who have trouble sleeping. Participants will receive either gabapentin, tizanidine, or a placebo (a harmless pill with no active medicine) to compare effects on sleep. This trial suits those who have experienced pain for at least three months and struggle with sleep issues. Participants must communicate in English and have email access for completing surveys. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.
Do I need to stop my current medications for the trial?
The trial information does not specify if you need to stop your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that gabapentin is generally well-tolerated. Since 1993, it has been used and approved by the FDA for treating seizures and nerve pain. Some studies suggest it can improve sleep without causing many serious side effects. However, warnings exist about possible breathing problems, especially when combined with medications like opioids.
Tizanidine, in contrast, relaxes muscles and can induce sleepiness, aiding some people with muscle pain in sleeping better. Although commonly used, tizanidine is not specifically approved by the FDA for sleep disorders.
Both gabapentin and tizanidine have been studied in various contexts and are considered relatively safe when used properly. Always consult a healthcare provider to understand any potential risks based on personal health needs.12345Why are researchers excited about this trial's treatments?
Researchers are excited about these treatments because they offer a fresh approach to tackling insomnia associated with chronic pain. Gabapentin and Tizanidine, the drugs being studied, work differently from typical sleep medications like benzodiazepines or non-benzodiazepine sleep aids. Gabapentin, primarily used for nerve pain, might help improve sleep by calming nerve activity, while Tizanidine, a muscle relaxant, can help ease muscle-related discomfort, potentially aiding in better sleep quality. Unlike standard treatments that mainly target sleep directly, these drugs could address the underlying pain issues contributing to insomnia, offering a dual benefit. This approach could lead to more effective relief for individuals struggling with both chronic pain and sleep disturbances.
What evidence suggests that this trial's treatments could be effective for insomnia in chronic pain?
Research shows that gabapentin, one of the treatments in this trial, can improve sleep by increasing both duration and depth. It helps individuals stay asleep longer and reduces the time spent awake after initially falling asleep. For those experiencing ongoing pain, gabapentin can lessen pain, potentially leading to better sleep.
Tizanidine, another treatment option in this trial, has improved sleep quality for individuals with long-term muscle pain. Studies indicate it can reduce pain levels and enhance overall sleep. This trial examines both gabapentin and tizanidine for their potential to alleviate insomnia in people with chronic pain.14678Who Is on the Research Team?
