The purpose of this study is to investigate the efficacy and safety for a marketed sinus allergy product, Sinutab, in the treatment of nasal congestion and headache.

In response to a mandated requirement from the Belgium Medicines Agency - rising from the perforce switch of Sinutab® to a 2 active ingredients Pseudoephedrine+Paracetamol combination - we have made a commitment to demonstrate the safety and efficacy of Sinutab®.

In agreement with the Medicines Agency, an in-use Pharmacy-based study has been designed to demonstrate efficacy and safety of Sinutab® for the approved indications (symptomatic relief in the common cold).

This will be a randomized, double blind, placebo-controlled, comparative phase 4, multi-centre study in parallel groups between Sinutab and placebo. To study the drug in it's 'natural environment', community pharmacists will function as local investigators. Approximately 25 community pharmacists will be carefully selected, and only be taken into consideration if appropriate software programs are used in their pharmacy.

This implicates that the pharmacist has a medication record of his patients at his disposal which he will use to check the exclusion criteria. They will include subjects with early (≤ 48 hours) cold symptoms of blocked nose with headache. Subjects fulfilling the inclusion/exclusion criteria will be assigned to one of the two treatment groups, according to a computer-generated randomization list. A sufficient number of subjects will be randomized in the order of their enrolment, targeting at 300 evaluable subjects at the conclusion of study.

The following information will be collected every evening from subjects during 7 days: symptom assessment, compliance, adverse events and the ability to go to work or school.

Inclusion Criteria:

• age 18 years or more
• reported cold symptoms beginning ≤ 48 hours prior to visit 1
• scored ≥ 2 for each of nasal congestion and headache using the Modified Jackson Subject Evaluation Scale
• willing and able to comply with scheduled visits, treatment plan, and other study procedures
• evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the trial

Exclusion Criteria:

• patients without an electronic medication record in the pharmacy
• history of hypersensitivity to paracetamol or pseudoephedrine or lactose
• fever more than 38.0°C (measured by pharmacist)
• women in the fertile years who do not use a hormonal contraception or an intra-uterine device
• use of concomitant drugs, medications or treatments that could interfere with the study drug
• important intercurrent medical condition based on the available medication record of the patient. (cf. exclusion criterium 1)
• history of nasal reconstructive surgery
• alcohol and/or drug abuse within a 6-month period immediately preceding the screening visit
• any medication or indication that might point to an increased risk, associated with study participation or study drug administration or may interfere with the interpretation of study results and, in the judgment of the study personnel, would make the subject inappropriate for inclusion
• participation in other clinical trials the last three months and during study participation.
• employees of the clinical research centers, sponsor, the CRO's contracted for this study, or their immediate family members
