Primary Outcome Measures
NameTimeMethod
Efficacy Rate (Percentage) of Patient's Impression2 hours post-additional dose

Patient's impression was assessed by self-report and was entered in the patient diary, based on the following categories: "Excellent", " Good", "Fair" and "Poor".

Efficacy rate was calculated from the following formula, "The number of participants assessed as Excellent or Good" over "total participants" multiplied by 100.

Secondary Outcome Measures
NameTimeMethod
Differences in Pain Intensity (PI) Measured by VAS Among ParticipantsPre-additional dose (baseline) and 2 hours post-additional dose

The differences in PI were obtained by subtracting the PI at each time point from the Baseline PI score.

Number of Participants in Each Pain Intensity (PI) With 4 Categories2 hours after additional dose

Pain intensity was entered in the patient diary on the following categories: "No pain", "Mild pain", "Moderate pain" and "Severe pain".

Pain Intensity Measured by Visual Analog Scale (VAS)2 hours post-additional dose

The Pain intensity was recorded on the 100 mm VAS in the patient diary, where 0 mm=no pain, 100 mm=unbearable maximal pain.
