Mentholated Cream Containing Oxygenated Glycerol Triesters on Acute Pain of the Muscles and Joints

Study Overview
=================
Brief Summary
-----------------
A single center trial to evaluate the efficacy, tolerance, and acceptability of Oxygenated Glycerol Triesters (OGT) mentholated cream on acute musculoskeletal pain in normal healthy adult volunteers suffering from a recent inflammation of muscles and joints. Patient who met eligibility requirements were instructed to identify one area on their body where they were experiencing the most acute musculoskeletal pain/discomfort. Patients were provided with visual analog scales in order to quantify their pain. Patients either received mentholated cream with or without OGT and instructed to rub on the identified site 3 times a day for 7 days. Pain and other observations were written in a diary for each day.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity of Pain | Patients were instructed to identify one area on their body where they were experiencing the most acute musculoskeletal pain/discomfort. |  | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Limitation of Activity | How limited patient activities were due to the pain associated with the area of interest. |  | 
| Evaluation of the mobility of the painful joint/muscle | Patient assessed how mobile their joints/muscles were within the area of interest. |  | 
| Skin Toxicity | Tolerability was assessed from Redness and Dryness VAS recorded by the clinical evaluator. No formal safety testing was performed in this study; however anecdotal information (stinging, burning, itching, etc.) was captured on the subjects' diaries. |  |
