Cartilage is the tough elastic tissue found in the nose, throat, ear and joints. It is like a cushion at the ends of the bones. The cartilage between joints acts as a shock absorber, protecting the bones and tissues from the impact created during walking and other bodily movements.
Tendons are like rubber bands stretched over joints that keep muscles attached to bones.
Ligaments are the soft tissues that attach bones to bones.
Ligaments are very similar to tendons. The difference is that tendons attach muscles to bones. Both of these structures are made up of small fibers of a material called collagen. The collagen fibers are bundled together to form a rope-like structure. Ligaments and tendons come in many different sizes, and like rope, are made up of many smaller fibers. The thicker the ligament (or tendon) the stonger it is, for example the large Achilles tendon is the most important tendon for walking, running, and jumping. Sometimes, tendons and ligaments slide out of their spot at the joint and then quickly snap back into place.
Q. What is ibuprofen?
A. Ibuprofen is medication called a Non-Steroidal Anti-Inflammatory Drug, NSAID. Ibuprofen works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostagladins are produced in response to injury, certain diseases and various conditions, which cause pain, swelling and inflammation. Ibuprofen blocks the production of these prostaglandins and is therefore effective at reducing inflammation and pain.
Q. What is topical ibuprofen?
A. Topical ibuprofen is used for 2 purposes; to help reduce inflammation below the skin surface and alleviate nerve pain such as muscular and joint pain, spasms, neck and low back pain, and pain associated with strain or injury.
When ibuprofen is applied to the skin (topical application) it is absorbed through the skin into the underlying tissues, where it reduces pain and inflammation in the local area. NSAID's (non-steroid anti-inflammatory drugs, such as ibuprofen) administered as cream, quickly penetrate through the outer layer (of the skin) at the application site and reach highly effective concentrations deep in the tissue such as tendons, ligaments, and muscles. It is estimated that as much as 95% reach the target area. Blood levels of topical NSAIDs are extremely low with no systemic side effects. By contrast, oral NSAIDs lead to high blood levels but a lower concentration at the targeted site of pain and are estiamted to be less than 5% in the soft tissue.
Q. Is it new?
A. Topical anti-inflammatory creams have been available in Europe for 15 years and are extremely popular. There is four decades of research studies done on topical ibuprofen.
Q. What is the advantage of using ibuprofen?
A. Topically, ibuprofen is very advantageous for several reasons. The stomach and digestive tract are not exposed to the normal side effects of oral pain relievers, such as stomach pain or increased risk of ulcers. The risk of kidney and liver damage as well as cardiovascular problems, such as heart attack and stroke, should be reduced because the active ingredients remain in the skin and do not enter the blood to any real extent. The rest of the body does not have to be exposed to unwanted medication--only the site of pain.
Studies have shown that levels of topical ibuprofen can be 4 to 7 times higher in the cartilage than oral ibuprofen. Results from oral preparations delivered to a targeted site of pain are less than 5%. Onset of symptom relief in some cases may be faster that oral preparations and relief may last longer.
Q. What is it used for?
A. Topical ibuprofen is used for pain and inflammation such as muscle pain, rheumatic pain, sprains, strains, sports injuries, and pain from non-serious arthritic conditions.
Q. Why combine glucosamine with ibuprofen?
A. The November 2003 issue of Journal of Pharmacology and Experimental Therapeutics reported the findings of Temple University researchers that popular nutritional supplement glucosamine, administered with ibuprofen, synergistically boosts the ability of the drug to relieve pain.
When compared on osteoarthritis ibuprofen works faster, within 2 weeks. However, at eight weeks glucosamine is slightly more effective at reducing pain.
Q.Are there any cautions is using topical ibuprofen?
A. Topical ibuprofen is for external use only. Do not apply to broken skin. Avoid contact with the eyes and the moist membranes lining the inside of certain parts of the body, such as the mouth and nasal passages (mucous membranes). Rinse with cold water if accidental contact occurs. You should not cover the area being treated with airtight dressings such as bandages or other dressings. Wash your hands thoroughly after applying this medication, unless the hands are the area being treated. Seek medical advice from your doctor or pharmacist if your symptoms persist or worsen despite treatment. If you experience any side effects from this medicine, in particular a rash, stop using it and seek medical advice. Do not use if you are allergic to ibuprofen. Ibuprofen cream is not recommended for children under 12 years of age unless instructed by a doctor. Not indicated during pregnany and breastfeeding unless approved by a doctor.
Q. Is topical ibuprofen more costly than oral ibuprofen?
A. Two studies have compared the cost of a topical NSAID with an oral NSAID (generic ibuprofen), and examined costs over one month and three months. Both studies concluded that total costs of topical NSAIDs were lower than those of oral NSAIDs, and for the same reason--because of lower adverse event rates. Higher acquisition costs for topical NSAIDs were offset by lower adverse event costs which results in savings for the whole health economy. Oral NSAIDs are associated with significant gastrointestinal adverse events. Topical NSAIDs have much lower plasma concentrations, and are not associated with higher rates of adverse events, or at any rate of gastrointestional adverse events.
Topical Versus Oral Ibuprofen
Topical Administration---------------------------------Oral Administration
Low Blood Levels --------------------High Blood Levels
After a single application=500ng/ml -----After a single dose (400mg)=20,000ng/ml
Levels in cartilage 4-7 x higher---------Levels in cartilage 4 x 7 lower (proving direct absorption into joints does occur)
Levels in tendons several hundred x higher---Low levels in tendons
Low levels of Gastrointestional events-------High levels of Gastrointestional adverse events
Q. What are the prescrtiption drugs for arthritis?
A. Cox-2 Inhibitors, such as Celebrex and other Non-Steriod Anti-Inflammatory Drugs, NSAIDs, such as ibuprofen (Motrin, Advil, Rufen, Nuprin), naproxen (Naprosyn, Naprelan, Anaprox, Aleve), nabumetone (Relafen), ketorolac, sulindac, and diclofenac (Cataflam, Voltaren). The class of drugs known as Cyclo-oxygenase-2 inhibitors that emerged in the late 1990s for dealing with arthritis pain, such as the brand names Celebrex and Vioxx, are also considered part of the group of NSIADs.
Due to increased risk of heart attacks and strokes Vioxx was voluntairly pulled off the market by its manufacturer.
Q. What are side effects of NSAIDs?
A. The major side effects of NSAIDs are related to their effects on stomach and bowels (gastrointestional system). Some 10% to 50% of patients are unable to tolerate NSAID treatment because of side effects, including abdominal pain, diarrhea, bloating, heartburn, and upset stomach. Approximately 15% of patients on long term NSAID treatment develope ulceration of the stomach and duodenum. Even though many of these patients with ulcers do not have symptoms and are unaware of their ulcers, they are at risk of developing serious ulcer complications such as bleeding or perforation of the stomach.
Q. How do NSAIDs work and how do they cause stomach problems?
A. Prostaglandins are natural chemicals which are involved in body inflammation. By inhibiting the body's production of certain chemical messengers (prostaglandins), NSAIDs decrease inflammation. However, certain prostaglandins are also important in protecting the stomach lining from the corrosive effects of stomach acid as well as playing a role in maintaining the natural healthy condition of the stomach lining. These prostaglandins are produced by an enzyme called Cox-1. By blocking the Cox-1 enzyme and disrupting the production of prostaglandins in the stomach, NSAIDs can cause ulcers and bleeding. Some NSAIDs have less effect on the stomach prostaglandins than others, and, therefore a lower risk of ulcer formation.
Q. Are Cox-2 inhibitors safer?
A. Cox-2 inhibitor drugs are generally considered a safer alternative to non-steroidal anti-inflammatory drugs (NSAIDs), but Cox inhibitors are not without gastric side effects. In fact, the Cox-2 inhibitors have been associated with gastrointestional side effects, particularly in people with a history of gastrointestional disorders. In those who have inflammatory bowel disease (Chron's disease or ulceratative colitis), Cox-2 inhibitors have been found to cause gastrointestional side effects, including relapse of symptoms, requiring cessation of treatment in 25% of patients.
A new study published in the Journal of Immunology identifies a potential long-term problem that could lead to cartilage and other tissue degeneration if these drugs are taken over an extended time period. The authors of this study found that Cox-2 inhibitors cause metabolic imbalances that have been shown to play a role in the cartilage destruction and the inflammation process.
Another problem with inhibiting the Cox-2 enzyme is that metabolic imbalances occur, resulting in an overdose of byproducts that damage the arterial wall and induce arterial blood clotting.
Q. What are the side effects of oral NSAIDs?
A. Prehaps the most notable side effect for people suffering with chronic joint pain is that NSAIDs have a propensity to make cartilage deteriorate, according to an article in the American Journal of Medicine as early as 1987.
(Brandt KD. Effects of nonsteridol anti-inflammatory drugs on chondrocyte metabolism in vitro and in vivo. Am J Med. 1987 Nov 20;83(5A):29-34.)
There are also very considerable evidence that oral NSAIDs produce significant upper gastrointestional adverse events because of gastroduodenal ulceration, and, in some cases, bleeding. These require hospital treatment or prophylaxis with proton pump inhibitors to prevent these adverse events. Gastrointestional adverse events are known NOT to be associated with topical NSAID use.
General risks: gastrointestional side effects, renal insufficiency, hepatic toxicity, exacerbation of asthma, sodium retention, raised blood pressure and resistance to anti-hypertensive drugs, and increased risk of iron deficency or iron deficiency anemia.
Around 40% of hospital admissions with upper gastrointestional bleeding, and 40% of associated deaths in older people are related to NSAID use.
Recent research also has found that the use of NSAIDs increases the risk of erectile dysfunction in middle-age and elderly men.
Q. What is the pain patch?
A. The FDA has issued a health advisory regarding the safe use of fentanyl skin patches (brand name Duragesic) in response to reports of deaths in patients using this potent narcotic medication for pain management.
The FDA is conducting an investigation into the deaths associated with these pratches. It's unclear if the deaths are due to inappropiate use of the patch or factors related to the quality of the product, according to the advisory.
Deaths and overdoses have occured in patients using both the brand name product Duragesic and the generic product Fentanyl. The directions for using the Fentanyl skin patch must be followed exactly to prevent death or other serious side effects from overdosing with Fentanyl, according to the FDA.

Topical NSAIDs relieve osteoarthritis pain for only two weeks but there is no evidence that topical NSAIDs cure arthritis pain long term.
* BMJ, January 1998.
Reported that topical NSAIDs were effective in relieving pain in acute conditions like sprains ans strains. Authors Conclusions: Topical NSAIDs were effective and safe in treating acute painful conditions for one week.
*J Accid Energ Med, Sept 1994.
Evaluation of topical cream in the treatment of acute sprains. One hundred patients who presented to the accident and emergency (A&E) department with an acute ankle sprain. Patients using the topical ibuprofen cream had significant reduction in pain scores over the first 48 hours of treatment.
*Journal of Clinical Pharmacy & Therapeutics. (December 2002)
Comparative efficancy of a proprietary topical ibuprofen gel and oral ibuprofen in acute soft tissue injuries. Summary: The efficacy of a novel, proprietary topical formation of ibuprofen 5% gel and ibuprofen 400 mg tablets (1200 mg daily) acute soft tissue injuries. The two treatments showed similar efficancy. In summary: Ibuprofen gel shows similar efficancy to oral ibuprofen 400 mg and may offer improved tolerability.
* Health Technol Asses, 1997
Topical NSAIDs are effective in rheumatological conditions with few adverse events.
* German journal, 1999
Essentially the entire oral dose is excreted in urine during 24 hours but only .55% of the topical dose is excreted during 24 hours, suggesting that if target tissue concentrations correlate directly with the degree of pain relief, patients with pain caused by dermal or subcutaneous tissue damage will have greater pain relief after topical administration of ibuprofen with less systemic side effects
Additionally, some patients with muscle pain may also experience pain relief from topical ibuprofen.
Q. What is Glucosamine?
A. Glucosamine is a natural remedy that has been found to be useful in promoting healthy joints. In Europe glucosamine is approved as a drug for osteoarthritis. It is a natural substance made by the body that provides the raw material needed to repair the connective tissue found in skin, tendons, ligaments, and joints. Animal studies show that when an injury occures levels of glucosamine in the body increases.
Q. Are there studies proving Glucosamine is effective?
A. Supplemental glucosamine appears to provide the material necessary for joint repair. Research has also demonstrated that glucosamine also has the ability to delay the progression of the disease. It does this by inhibiting certain enzymes, which destroy the cartilage. Furthermore, it has been shown to relieve symptoms even for weeks after termination of the treatment.
Many studies confirm the efficacy of glucosamine. Recently all of the published studies done on glucosamine were reviewed. In all, there were 13 of these studies (six involving glucosamine and seven involving chondroitin sulfate). All 13 studies found positive results in hip and knee osteoarthritis.
Even the prestigious, Journal of the American Medical Association (JAMA) in the March 15, 2000 issue, reviewed all known studies on glucosamine and chondroitin in the treatment of arthritis. The conclusion of the authors was: "Trials of glucosamine and chondroitin preparations for osteoarthritis symptoms demonstrate moderate to large effects..."
Glucosamine alone or in conjunction with chondroitin sulfate may have the ability to repair and improve joint function in addition to providing pain relief.

Q.How do we know that glucosamine and chondroitin are effective used topically?
A. Published studies on topical glucosamine have demonstrated outcomes of reduced joint pain, less stiffness and increased function of the affected joints.
J Rheumatol. 2003 Nov;30(11)2512. A radonmized, double blind, placebo controlled trial of a topical cream containing glucosamine sulfate, chondroitin sulfate, and camphor for ostearthritis of the knee. CONCLUSION: Topical applicatiion of glucosamine and chondroitin sulfate is effective in relieving the pain from OA of the knee and improvement within 4 weeks.
Q. Where does it come from?
A. The glucosamine used in supplements is typically derived from the shells of crabs, although a corn source is also available.
Q. Why should glucosamine be used in conjunction with MSM?
A. In a new study, the combination of glucosamine with MSM was found to be more effective in improving the signs and symptoms of osteoarthritis than the use of either agent alone. The study authors concluded that the combination of glucosamine with methylsulfonylmethane (MSM) provides better and more rapid improvement in patients with osteoarthritis than either agent alone.

Q. How long does it take to work?
A. As with most natural remedies the therapeutic effect of glucosamine usually takes some weeks to appear (1-8 weeks). Once achieved, it tends to persist for a notable time even after discontinuation of the treatment.
Q. Why combine Glucosamine with Ibuprofen?
A. The November 2003 issue Journal of Pharmacololgy and Experimental Therapeutics reported that the findings of Temple University researchers that the popular nutritional supplement glucosamine, administered with ibuprofen, synergistically boosts the ability of the drug to relieve pain.
When compared on osteoarthritis ibuprofen works faster, within 2 weeks. However, at eight weeks glucosamine is slightly more effective at reducing pain.
Q. What about the safety of Glucosamine?
A. Glucosamine is generally expected to be safe since it is a substance normally used by the body.
Q. How does taking Glucosamine compare to taking NSAIDs for arthritic pain?
A. Clinical evidence suggests that glucosamine helps maintain the joint space and may help rebuild damaged cartilige. By contrast, oral NSAIDs have a propensity to make cartilage deteriorate. Glucosamine also inhibits certain enzymes that destroy cartliage. By blocking pathogenic mechanisms that lead to joint degeneration, glucosamine delays the progression of osteoarthritis and relieves symptoms even for weeks after termination of the treatment.

Q. Are there contraindications to glucosamine?
A. There are no known contraindications to glucosamaine supplementaion. Glucosamine appears safe and has few short-term side effects. Pregnant women, children, and very elderly people should avoid glucosamine since no studies among these specific populations exists. Patients taking blood-thinners should be extremely careful if they take glucosamine combined with chondroitin.
Q. Are there side effects to Glucosamine?
A. Side effects that have been reported are on oral glucsoamine and are mainly mild gastrointestional complaints such as heartburn, epigastric distress and diarrhea. No allergic reactions have been reported including sulfa-allergic reactions to glucosamine sulfate. These have not been measured or demonstrated topically.
Q. What is Chondroitin sulfate?
A. Chondroitin sulfate is a major component of cartilage. As in the case of glucosamine, chondroitin sulfate also works by attracting water into the cartilage matrix and stimulating the production of cartilage. This is essential in order for healthy cartilage to recieve nutrients and to protect the cartilage from wear and tear.
Another similarity is that chondroitin sulfate is also believed to prevent enzymes from dissolving cartilage, slowing progress of joint degradation. Recent studies have shown very good results from long-term treatment with chondroitin sulfate, reducing pain and increasing range of motion.
Q. Are there side effects asssociated with taking chondroitin sulfate?
Side effects that have been reported are mainly mild gastrointestional complaints such as heartburn, epigastric distress and diarrhea. No allergic reactions have been reported including sulfa-allergic reactions to glucosamine sulfate.
Q. Where does chondroitin sulfate come from?
A. Chondroitin sulfate is generally derived from cow cartilage, but porcine (pig) and even chicken cartilage has been used and algae are another potential source.
Q. Are there contraindications or interactions to chondroitin sulfate?
A. There are no known contraindications. There are no known drug, nutrient, food or herb interactions. Chitosan (see Chitosan) may form complexes with chondroitin sulfate decreasing its absorption. Therefore, chondroitin sulfate should not be used concomitantly with chitosan.
Q. Are there any side effects to chondroitine sulfate?
A. Because of insufficient safety data, children, pregnant women and nursing mothers should avoid using chondroitin sulfate. Because of the theoretical possibility that chondroitin sulfate may have anti-thrombotic activity, those taking warfarin and those with hemophilia should exercise caution in its use. Those who need to restrict their salt intake should, if they use chondritin sulfate, use salt-free preparations.
Side effects from oral usage that have been reported are mostely of the mild gastrointestinal variety, such as epigastric distress, nausea and diarrhea. No sulfa-allergic reactions or other allergic reactions have been reported. These have not been measured topically.
Q. What is MSM?
A. Methylsulfonymethane, abbreviated MSM, is an organic sulfer-contining compound. MSM occurs naturally in a variety of fruits, vegetables, grains and in animals, including humans in at least trace amounts. MSM has also been found in such plants as Equisetem arvense, also known as horsetail. MSM is produced by the body as a result of the foods we eat.
MSM finds its way into the collagen of skin, joints, and blood vessels. It is also incorporated in the keratin of hair and nails. The body's concentration of MSM tends to decrease with age. Some research suggests a minimum concentration of MSM must be maintained in the body to preserve normal function and structure.
Q. What does MSM do?
A. MSM is a natural remedy that may benefit individuals with arthritis, act as a natural analgesic and anti-inflammatory substance. MSM is a small but highly effective molecule that may inhibit pain impulses along nerve fibers, quell inflammation, increase blood supply, reduce muscle spasms, and soften scar tissue. MSM is thought to relieve pain and inflammation in osteoarthritis, rheumatoid arthritis, lupus, scleroderma, and fibromyalgia. It has also been reported to be helpful in allergies, back pain, headaches, temporomandibular joint dysfunction (TMG), Tendonitis, and more.
Q. What so studies on MSM show?
A. Animal studies have shown that joints affected by osteoarthritis have lower sulfer content, and that arthritic mice given MSM experience less joint degeneration. In a human trial in people with osteoarthritis, subjects who recieved MSM experienced significant pain relief.

Q. Are there any safety concerns or contraindications for MSM?
A. MSM is thought to be safe and nontoxic. There are no known contrindications. MSM should be avoided by pregnant women and nursing mothers due to lack of studies. It is generally believed that people who are allergic to sulfa drugs or do not tolerate sulfite preservatives in foods need not be concerned about the use of MSM and glucosamine sulfate--that these do not give rise to allergic reactions. However, there are reports of individulas who are reactive, so caution is advised.
Q. What is Bromelain?
A. Bromelain is an enzyme derived from pineapple stems. It is believed to inhibit the root cause of inflammation within the body by adjusting the hormones that trigger inflammation. Bromelain's anti-inflammatory enzyme is thought to possess the ability to break down or dissolve proteins which help to reduce muscle and tissue swelling, especially following injuries or surgery, and as indicated by research dental surgery and musculoskeltal trauma.
Q. Is there scientific research on Bromelain?
A. Yes as cited below:
* (MacKay D. et al 2003) Use of oral bromelain over the postoperative period results in faster resolution of swelling and decreased dependence of analgesics in fracture patients (Kamenicek V et al 2001).
* Similar resutls have been recorded after dental surgery (Tassman G et al 1964) and musculoskeletal trauma (Masson M 1995).
