Trial Outcomes & Findings for Maxigesic 325 Acute Dental Pain Study (NCT NCT01420653)

NCT ID: NCT01420653

Last Updated: 2018-12-06

Results Overview

The time-adjusted Summed Pain Intensity Differences (SPIDs) of the VAS pain intensity scores up to 48 hours after the first dose of study medication. This was calculated from the visual analogue scale (VAS) pain intensity scores recorded during the 48 hours double blind treatment period, with the last measure taken just prior to the final dose of blinded study medication. The visual analogue scale is 100mm long with 0= no pain and 100=worst pain imaginable. The Visual Analogue Scale It is expected that treatments which can provide superior analgesic effect will demonstrate a greater Summed Pain Intensity Difference.
