Delayed Onset Muscle Soreness | A Study Comparing the Efficacy and Safety of Orally Administered Ibuprofen and Placebo in Delayed Onset Muscle Soreness

Delayed Onset Muscle Soreness research study

What is the primary objective of this study?

The hypotheses to be tested are: Efficacy: Ibuprofen will be more effective than the Placebo in relieving muscle pain/soreness over 48 hour post-dosing with study medication. Safety: There will be no or minimal increased incidence of adverse events (AEs) with Ibuprofen versus and both will be well tolerated.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Acetaminophen 1000mgSubjects who require rescue medication between hours 4 and 6 will be allowed to take Dose 2 of the study medication. If the subject chooses to take a rescue analgesic (acetaminophen 1000mg), they will be considered a treatment failure. This intervention will be use for the placebo and Ibuprofen arm.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Placebo2 capsules identical to comparator, 3 times daily on Day 1 and Day 2. On Day 3 only one dose will be taken. The intervention is Acetaminophen 1000mg.

Ibuprofen2oomg capsules (400 mg per dose), 3 times daily on Day 1 and Day 2. On Day 3 only one dose will be taken. The intervention is Acetaminophen 1000mg.
