Trial Outcomes & Findings for To Evaluate the Safety and Efficacy of Acetaminophen 650 mg and 1000mg in Dental Pain After Surgery (NCT NCT01115673)

NCT ID: NCT01115673

Last Updated: 2012-05-28

Results Overview

Weighted Sum of Pain Intensity Difference and Pain Relief Scores Over Six Hours (SPRID6) - pain intensity and pain relief were evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no pain and 100 = very severe pain for pain intensity and 0 = no relief and 100 = complete relief for pain relief. For SPRID6, the total possible minimum value is -300 (worst) and the total possible maximum value is 1200 (best). The weights used in the calculation of weighted sums were equal to the elapsed time (hour) between the time point of interest and the preceding time point.

PRIMARY outcome

Timeframe: 6 Hours

Population: Analysis is based on the Intent-to-Treat (ITT) set, which included all subjects who were randomized, took study medication, did not vomit within 60 minutes after dosing, and had a baseline pain score and at least one post-randomization assessment.

Weighted Sum of Pain Intensity Difference and Pain Relief Scores Over Six Hours (SPRID6) - pain intensity and pain relief were evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no pain and 100 = very severe pain for pain intensity and 0 = no relief and 100 = complete relief for pain relief. For SPRID6, the total possible minimum value is -300 (worst) and the total possible maximum value is 1200 (best). The weights used in the calculation of weighted sums were equal to the elapsed time (hour) between the time point of interest and the preceding time point.

Pain Intensity Difference (PID) from Baseline at Each Assessment Time point - pain intensity was evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no pain and 100 = very severe pain with a highest possible score of 100. The pain intensity difference was calculated at each time point as the pain intensity score at baseline minus the pain intensity score at the stated time point.

Timeframe: 360 Minutes

Population: Analysis is based on the Intent-to-Treat (ITT) set, which included all subjects who were randomized, took study medication, did not vomit within 60 minutes after dosing, and had a baseline pain score and at least one post-randomization assessment.

Pain Relief Scores at each Assessment Timepoint - pain relief was evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no relief and 100 = complete relief with a highest possible score of 100

Minutes until confirmed perceptible pain relief was achieved. A stopwatch was provided to the subject after ingestion of the study medication. The subject was instructed to stop the stopwatch when they first began to feel any pain relieving effect whatsoever of the drug, that was when they first felt any pain relief. It did not necessarily mean they felt completely better, although they might have, but when they first felt any difference in the pain.
