Plain English summary of protocol
Background and study aims
A DHEP medicated plaster contains 180 mg of a diclofenac salt, named diclofenac epolamine or DHEP, and it allows a continuous release of the drug from the plaster during the application period. This plaster has been marketed by many years in Europe and USA for the local treatment of pain and inflammation of traumatic and rheumatic origin. Our goal was to demonstrate how well the DHEP plaster works for the treatment of minor soft tissue injuries in the Chinese population.
Who can participate?
Adult male and female patients (18-65 years) with a minor soft tissue injury, such as ankle or knee joint sprain, muscle strain or contusion, which has occurred within the last 72 hours.
What does the study involve?
Participants were randomly allocated to one of two groups. One group of patients applied two DHEP plasters per day, each for 12 hours, for 7 days. The other group applied a placebo (dummy) plaster instead. During the study the severity of pain was measured using an established scale. The safety was also assessed by blood and urinalysis at the beginning and at the end of the study.
What are the possible benefits and risks of participating?
The participants who received the DHEP plaster can expect an improvement of their pain symptoms. The most common side effects seen with DHEP plasters are skin reactions (including itching, inflamed skin, burning) at the site of treatment.
Where is the study run from?
From 10 medical centres in China, with Peking University First Hospital in Beijing as lead centre.
When is the study starting and how long is it expected to run for?
The study started in April 2010 and ended in November 2010 when the required number of 384 patients (192 for each group) was recruited and treated.
Who is funding the study?
IBSA Institut Biochimique (Switzerland)
