Actual Use Trial of Naproxen Sodium

Bayer778 enrolled

Overview

An actual use trial to demonstrate that consumers will not exceed the labeled daily dose of Aleve 24 Hour at an unacceptable rate. Two aspects of consumer use will be evaluated: 1) the frequency at which consumers exceed the label-defined daily dose, thus putting themselves at clinical risk, and 2) the reasons for exceeding the labeled daily dose.

Outcomes

Primary Outcomes

Estimated Percentage of Misuse for Non-Therapeutic Reasons

The primary objective of this trial was to determine the percentage of non-therapeutic misuse. Two aspects of consumer use of Aleve 24 Hour were examined: the frequency at which consumers exceeded the label-defined daily dose modified by those who did so for non-therapeutic reasons.

Time frame: 28 days

Secondary Outcomes

Non-therapeutic Reasons for Misuse

Those subjects in the Reasons for Misuse Cohort who did not state misuse due to need for additional pain relief were categorized to Non-therapeutic misuse.

Time frame: 28 days

Estimated Percentage of Misuse for Non-Therapeutic Reasons Using the First 10-Day Treatment Course

This endpoint was an assessment of whether the rate of non-therapeutic misuse exceeded the pre-defined acceptable threshold for non-therapeutic misuse. The difference lay in the estimation of misuse in the Patterns of Use Cohort by using 10-day treatment courses rather than by "use day". A treatment course for each subject began on the first day they recorded taking one or more tablets which was followed by nine consecutive "evaluable days."

Time frame: 28 days

Percentage of Participants Took >/= 2 Tablets/Use Day in Any 10 Use Days

Percentage of participants took \>/= 2 tablets/use day in any 10 use days thus exceeding the label directions during a treatment course.

Time frame: 28 days

Percentage of Participants Who Took Product With Mean Daily Use >/= 2 Tablets /Use Day

Percentage of participants who took product with mean daily use \>/= 2 tablets /use day thus exceeding the label directions on any use day.

Time frame: 28 days

Percentage of Participants With at Least One Dosing Occasion Where More Than One Tablet Was Taken
