Delayed Onset Muscle Soreness
Conditions
Keywords
Delayed onset muscle soreness, DOMS
Brief summary
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.
Interventions
Subjects 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.
