The study population is a healthy population who are voluntarily participating in this clinical trial. This study will compare the PK profile after e.c. and oral application of the same dosage of ketoprofen and in a dosage range as intended for clinical use in OA. It will also indicate whether application on muscle will result in a different PK profile as compared to application on a joint. The intended use for Diractin® will be osteoarthritis of the knee MedDRA version: 9.1 Level: LLT Classifi

| Main Objective: Primary: – Evaluation of reduction in pain caused by muscle soreness after application of 200 mg ketoprofen from Diractin® per b.i.d. in comparison to placebo. – Evaluation of reduction in pain caused by muscle soreness after application of 100 mg ketoprofen from Diractin® b.i.d. in comparison to placebo. ;Secondary Objective: Secondary: –Evaluation of reduction in pain caused by muscle soreness after application of 100 mg ketoprofen from oral application b.i.d. in comparison to placebo;Evaluation of reduction in pain caused by muscle soreness after application of 200 mg ketoprofen from Diractin® in comparison to 100 mg ketoprofen from oral application b.i.d.; Evaluation of reduction in pain caused by muscle soreness after application of 100 mg ketoprofen from Diractin® in comparison to 100 mg ketoprofen from oral application b.i.d.; Evaluation of the plasma pharmacokinetics after single application; 100 mg ketoprofen from Diractin®; 200 mg ketoprofen from Diractin®;100 mg from oral ketoprofen; Comparison of the plasma pharmacokinetics after 7 days of b.i.d. application of –100 mg ketoprofen from Diractin® –200 mg ketoprofen from Diractin® –100 mg from oral ketoprofen –Evaluation of safety and tolerability of Diractin® in comparison to placebo and oral ketoprofen ;Primary end point(s): Primary endpoint : The area under the curve of muscle pain scores evaluated by a 10 point categorical pain scale at 15 min, 30 min, 1h, 2h, 4h, 8h, 12 h after the first application (the 12 h evaluation should be done immediately the before 2nd application) and then always before the next application. Secondary endpoints: The area under the curve of muscle soreness within the first 12 hours after the first application.
