RB Naproxen (Test) First, Then Aleve Naproxen (Reference)
Participants first received RB naproxen sodium 2 x 220 mg tablets single-oral dose in a fasting condition. After a washout period of 5-8 Days, they then received Aleve naproxen sodium 2 x 220 mg tablets single-oral dose in a fasting condition.

Timeframe: Up to follow-up day 7

Population: Safety population

Intensity was determined by the Investigator Mild = AE does not limit usual activities; subject may experience slight discomfort. Moderate = AE results in some limitation of usual activities; subject may experience significant discomfort. Severe = AE results in an inability to carry out usual activities; subject may experience intolerable discomfort or pain. Relationship to Investigational Medicinal Products (IMP) Certain = AE was definitely caused by IMP. Probable = Most likely that the AE was caused by IMP. Possible = Reasonable suspicion that the AE was caused by IMP Unlikely = Slight, but remote, chance that the AE was caused by IMP but the balance of judgment is that it was most likely not due to the IMP. Unrelated = No possibility that the AE was caused by IMP Un-assessable/Unclassified = Insufficient information to be able to make an assessment. Conditional/Unclassified = Insufficient information to make an assessment at present.
