Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Drug supplies will be packed and labelled according to a computer produced randomisation schedule by site. On randomisation, patients will be allocated a unique number in numerical sequence. Issue of the drug in sequence will ensure randomisation.
The investigator will be provided with the randomisation code for each patient as a code break envelope. The code will only be broken for an individual patient in an emergency case such as a serious adverse event that requires knowledge of what study drug was taken in order that the serious adverse event can be treated appropriately.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
SAS random code generator, will randomly assign patients to either placebo or active treatment.

Summary
Brief summary
This study is testing a new treatment for sore throat called flurbiprofen micro granules.
Flurbiprofen lozenges are approved by the Australian health authority, the Therapeutic Goods Administration (TGA) for the relief of pain, swelling and inflammation due to severe sore throat. In this study, tiny granules of flurbiprofen will be tested to determine if they too are effective in the relief of sore throat.
