Efficacy and Safety of Ibuprofen and Caffeine in Dental Pain

Phase 3

Completed

Conditions: Tooth Diseases
Pain, Postoperative

Interventions: Drug: ibuprofen + caffeine
Drug: ibuprofen
Drug: placebo
Drug: caffeine

Registration Number: NCT01929031

Lead Sponsor: Boehringer Ingelheim

Brief Summary: The primary objective of this study is to compare the efficacy of a combination product containing ibuprofen 400 mg and caffeine 100 mg versus either ingredient alone as well as placebo for the treatment of post-surgical dental pain over an eight-hour period followed by a single dose of study medication (study stage 1). A secondary objective is to evaluate efficacy of multiple doses of the combination in comparison to ibuprofen alone over a 5-day post-surgical period (study stage 2).

Primary Outcome Measures

Name	Time	Method
Time-weighted Sum of Pain Relief (PAR) and Pain Intensity Difference (PID) From 0 to 8 Hours (SPRID0-8h)	0 to 8 hours	SPRID0-8h: Time-weighted sum of PAR and PID from 0 to 8 hours, score range: -40 (worst) to 112 (best). PI was assessed on a 0-10 numerical pain rating scale (NPRS), where 0=no pain and 10=worst possible pain, pre-dose and at 0.25,0.5,0.75,1,1.5,2,3,4,5, 6,7 and 8 hours; PAR was assessed on a 5-point verbal rating scale (VRS) (0=none to 4=complete) at the same post-dose time points. Time-weights were equal to the elapsed time (hour) between the time point of interest and the preceding time point. All PAR and pain intensity (PI) assessments completed after the patient had taken rescue medication or the second dose of study medication, whichever was first, until hour 8 were considered missing. Last observation carried forward (LOCF) was used with the last completed PI/PAR assessments prior to first rescue/second study medication, whichever was first, to impute missing values up to 8 hours.

Secondary Outcome Measures

Name	Time	Method
Time-weighted Sum of Pain Relief (PAR) and Pain Intensity Difference (PID) From 0 to 2 Hours (SPRID0-2h)	0 to 2 hours	SPRID0-2h: Time-weighted sum of PAR and PID from 0 to 2 hours, score range: -10 (worst) to 28 (best). PI was assessed on a 0-10 numerical pain rating scale (NPRS), where 0=no pain and 10=worst possible pain, pre-dose and at 0.25,0.5,0.75,1,1.5 and 2 hours; PAR was assessed on a 5-point verbal rating scale (VRS) (0=none to 4=complete) at the same post-dose time points. Time-weights were equal to the elapsed time (hour) between the time point of interest and the preceding time point. All PAR and pain intensity (PI) assessments completed after the patient had taken rescue medication or the second dose of study medication, whichever was first, until hour 2 was considered missing. Last observation carried forward (LOCF) was used with the last completed PI/PAR assessments prior to first rescue/second study medication, whichever was first, to impute missing values up to 2 hours.
Duration of Pain Relief	8 hours	Duration of pain relief was defined as the time between the administration of first dose of trial medication and first dose of rescue medication or second dose of trial medication, whichever was first. Duration of pain relief was censored at 8 hours.
Time to Meaningful Pain Relief	8 hours	Time to meaningful pain relief was captured by a stopwatch, which was started by the study staff immediately after the administration of the first dose of trial medication and which was to be stopped by the patient as soon as he/she felt meaningful pain relief. Time to meaningful pain relief was censored at 8 hours.
