The present invention relates to the field of pain treatment.
Many people suffer from musculoskeletal conditions such as soft tissue trauma and arthritis. Some bear the pain associated with those conditions for prolonged periods. Treatment of musculoskeletal pain using anti-inflammatory drugs, such as non-steroidal anti-inflammatory drugs or NSAIDs, is not always effective.
Forming one aspect of the invention is a composition comprising, by weight:
Forming another aspect of the invention, the neuropathic analgesic can be Amitriptyline, the muscle relaxant can be Baclofen, the anesthetic can be Lidocaine and the anti-inflammatory analgesic can be Ketoprofen.
Forming another aspect of the invention is a topical composition comprising, by weight:
Further aspects of the invention will become apparent from the following description.
An exemplary embodiment of the invention is a composition comprising:
The oil phase is produced by mixing 50 parts granular soya lecithin, 50 parts isopropyl palmitate (USP-NF), and 1.3 parts sorbic acid (USP-NF) powder. The mixture is allowed to sit until a syrup that looks similar to motor oil is produced, which process takes a few hours.
The poloxamer 20% gel phase is produced by mixing 20 grams poloxamer 407, 0.3 grams potassium sorbate and 79.7 ml purified cold water, and allowing the resulting mixture to stand for approximately 24 hours in cold conditions, such as in a refrigerator.
It has been found that the composition can be used to treat musculoskeletal inflammation and/or pain resulting from various types of musculoskeletal conditions. For example, the composition can be used to treat soft tissue trauma pain and/or inflammation, arthritis, post-operative pain (e.g., resulting from scarring) and/or stiffness, neuropathic pain, joint pain, tendonitis, osteoarthritis, dermatomal pain, knee pain, hip pain, back pain, shoulder pain, wrist pain, neck pain, arm pain, ankle pain, sciatic pain, chronic pain, acute pain, or inflammation. In general, the clinical situations where the product has been found useful include patients who are waiting a long time for surgery as a result of long waiting lists. It is also useful in patients for whom surgery is contraindicated (advanced age, poor health etc). It has been found useful in the setting of acute pain following injury or exacerbation of underlying arthritis, in the management of post-operative pain and chronic pain and in the management of post-operative stiffness after total knee replacement by enabling more aggressive physiotherapy. In a survey of 60 patients using the product, 80% reported some form of relief. Of those who experienced relief, the average pain relief they reported was 67%. The only side effect reported was a rash in 3% of the patients surveyed. The rash resolved when they discontinued use.
For use, the composition is typically rubbed onto the skin in the areas of pain and/or inflammation, two to three times daily.
What follows is a random selection of exemplary results:
A 50 year old man with mild to moderate osteoarthritis of the knee had tried physiotherapy and bracing, with oral NSAIDs as needed. After six weeks of use of the cream, he reported significant pain relief and as a result, required less oral medication.
A 65 year old man with left hip arthritis pain and low back pain reported significant pain relief after using the cream. As a result, he decided to postpone a total hip replacement.
A 55 year old woman with osteoarthritis of the knee used viscosupplementation injections in conjunction with the cream, and as a result, reported significant pain reduction.
A 45 year old woman with greater trochanteric bursitis of the hip reported significant pain relief after using the cream.
Whereas only a single embodiment is hereby described in detail, variations are possible. Accordingly, the invention should be understood to be limited only by the accompanying claims, purposively construed.
