Plain English Summary
Background and study aims
Loxonin (loxoprofen sodium) is a kind of non-steroidal anti-inflammatory drug (NSAID). Loxonin tablets are widely used as a painkiller or anti-inflammatory, but like other NSAIDs, they have a number of side effects or adverse reactions (ADR’s). These may include heartburn, headaches, nausea, gastrointestinal problems (such as constipation or diarrhoea) and even intestinal or stomach ulcers. A Loxonin ointment, designed to be applied externally to the skin has therefore been developed in order to reduce the risk of ADR’s when taking the medication. Loxonin is widely used for myalgia (muscle pain). This study aims to compare the effectiveness and safety of the Loxonin ointment with Loxonin tablets for the treatment of myalgia.
Who can participate?
Patients aged 18 to 80 with moderate muscle pain on resting, pressing on the affected muscle or when exercising.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in group 1 (the study group) are treated with the Loxonin ointment once a day and a placebo (dummy) tablet three times a day. Those in group 2 (the control group) are treated with a placebo ointment once a day and a loxoprofen sodium tablet three times a day.
What are the possible benefits and risks of participating?
This product has been marketed in Japan for many years and as it’s an external application it’s relatively safe. Participants will receive the treatment for free and given appropriate economic compensation.
