The Effect of Paracetamol, Pseudoephedrine Hydrochloride, Dextromethorphan Hydrobromide and Chlorpheniramine Maleate Tablets Compared to Placebo in Subjects Suffering From the Common Cold or Influenza.

A Double-Blind, Randomised, Placebo-Controlled, Parallelgroup, Single-Dose Study to Evaluate Effect of Paracetamol, Pseudoephedrine Hydrochloride, Dextromethorphan Hydrobromide and Chlorpheniramine Maleate Tablets Compared to Placebo in Subjects Suffering From the Common Cold or Influenza Over a 4 Hour Period

This phase IV multi-centre, randomised, double-blind, placebo-controlled, parallel-group, single-dose study will assess the efficacy and tolerability of the active tablets versus placebo in participants suffering from cold and influenza. Eligible participants will be randomly assigned to one of 2 treatment groups (active or placebo tablets) and enter a four-hour (hr) treatment phase. Each participant will be administered only once during each study period. Participants will use a questionnaire to record the symptom severity scores as described, as well as time.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Symptom Severity Assessment at 15 Minutes	Symptom severity assessment was determined by Total Sum Score (TSS), TSS ranged from 0 to 21 with less severity score at the given time point represented a better outcome measure. TSS was calculated as the sum of the non missing scores (all on a 0-3 scale measuring worsening or severity) of the following common cold symptoms: sore throat, headache, extremities pain, nasal congestion, runny nose, sneezing, and cough post treatment administration. Participants self assessed symptoms severity using 4 points (0 = absent, 1 = mild, 2 = moderate, and 3 = severe) categorical scale at 15 minutes post product use.	15 minutes
Symptom Severity Assessment at 30 Minutes	Symptom severity assessment was determined by TSS, TSS ranged from 0 to 21 with less severity score at the given time point represented a better outcome measure. TSS was calculated as the sum of the non missing scores (all on a 0-3 scale measuring worsening or severity) of the following common cold symptoms: sore throat, headache, extremities pain, nasal congestion, runny nose, sneezing, and cough post treatment administration. Participants self assessed symptoms severity using 4 points (0 = absent, 1 = mild, 2 = moderate, and 3 = severe) categorical scale at 30 minutes post product use.	30 minutes
Symptom Severity Assessment at 1 Hour	Symptom severity assessment was determined by TSS, TSS ranged from 0 to 21 with less severity score at the given time point represented a better outcome measure. TSS was calculated as the sum of the non missing scores (all on a 0-3 scale measuring worsening or severity) of the following common cold symptoms: sore throat, headache, extremities pain, nasal congestion, runny nose, sneezing, and cough post treatment administration. Participants self assessed symptoms severity using 4 points (0 = absent, 1 = mild, 2 = moderate, and 3 = severe) categorical scale at 1hour post product use.	1 hour
Symptom Severity Assessment at 2 Hours	Symptom severity assessment was determined by TSS, TSS ranged from 0 to 21 with less severity score at the given time point represented a better outcome measure. TSS was calculated as the sum of the non missing scores (all on a 0-3 scale measuring worsening or severity) of the following common cold symptoms: sore throat, headache, extremities pain, nasal congestion, runny nose, sneezing, and cough post treatment administration. Participants self assessed symptoms severity using 4 points (0 = absent, 1 = mild, 2 = moderate, and 3 = severe) categorical scale at 2 hours post product use.	2 hours
Symptom Severity Assessment at 3 Hours	Symptom severity assessment was determined by TSS, TSS ranged from 0 to 21 with less severity score at the given time point represented a better outcome measure.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Global Assessment of Treatment	After completing the 4 hours symptom severity assessments, participants evaluated their treatment response on a 5-point scale by answering the question: "How well did the test medication control your symptoms?" (0-ineffective, 1-poor, 2-fair, 3-good, or 4-excellent).	4 hours
Sore Throat Severity Assessment	Participants self-assessed sore throat severity using 4 points (0 = absent, 1 = mild, 2 = moderate, and 3 = severe) categorical scale at baseline and at 15, 30, 60, 120,180 and 240 minutes post product administration.
