Metoclopramide vs Acetaminophen for Concussion

(IMPACT Trial)

This trial tests two common medications, metoclopramide (used for nausea) and acetaminophen (a pain reliever), to determine which better eases symptoms after a mild head injury, such as headaches, dizziness, or trouble concentrating. It targets individuals who recently experienced a concussion and are suffering from pain or other symptoms as a result. Participants should have sustained their concussion within the last week and be experiencing significant pain or post-concussion symptoms not present before the injury. The trial aims to improve concussion treatment in the emergency department by identifying the more effective medication. As a Phase 4 trial, this research involves FDA-approved treatments and seeks to understand how they can benefit more patients.

Research has shown that both metoclopramide and acetaminophen are generally well-tolerated. Studies have found that metoclopramide, often used in emergencies, is safe for short-term use and can help manage symptoms like nausea and headaches after a concussion.

Acetaminophen is widely recognized as a safe and effective treatment for headaches, including those from concussions. It is often recommended for relieving post-concussion symptoms such as pain and discomfort.

Researchers are excited about using metoclopramide and acetaminophen for treating concussions because they offer new ways to manage symptoms. Metoclopramide is typically used for nausea and migraines, and it might help with concussion symptoms by improving blood flow in the brain and reducing headache-related nausea. Acetaminophen is a pain reliever, and while it's commonly used, administering it intravenously can provide faster relief for concussion-related headaches compared to oral options. These treatments are being explored for their potential to provide quicker and more effective symptom relief than standard pain medications like NSAIDs.

This trial will compare Metoclopramide and Acetaminophen for treating concussion symptoms. Studies have shown that Metoclopramide can reduce headache pain in individuals with post-head injury headaches. Specifically, one study found that patients who took Metoclopramide experienced significant improvement compared to those who took a placebo, which contains no active medicine. Acetaminophen, a common pain reliever, can also aid in faster recovery from concussions. Research suggests that over-the-counter pain relievers like Acetaminophen help individuals resume normal activities sooner after a concussion. Both treatments have evidence supporting their effectiveness in managing post-concussion symptoms.⁶⁷⁸⁹¹⁰
