## Background
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS
This application claims priority to U.S. Provisional Patent Application 61/675,272, filed Jul. 24, 2012, the entire contents of which are incorporated herein by reference in their entirety.


BACKGROUND OF THE INVENTION
Joint conditions and the pain and disability associated with joint conditions affect millions of individuals. One such joint condition is arthritis, which involves inflammation of one or more joints. Osteoarthritis, in particular, affects 27 million Americans. This number is expected to increase as the median age in the U.S. continues to rise. Osteoarthritis, also known as degenerative arthritis or degenerative joint disease, is a group of mechanical abnormalities involving degradation of joints, including articular cartilage and subchondral bone. In some cases, symptoms include, for example, joint pain, tenderness, stiffness, locking, and the presence of increased intra-articular fluid.
SUMMARY OF THE INVENTION
Current medical strategies for treating osteoarthritis include pharmaceutical therapy (such as oral administration of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and narcotics or administration of steroid or joint lubrication injections), physical and occupational therapy, prescription of medical devices (such as splints, braces, and shoe inserts), and surgery including joint realignment surgery (osteotomy) and joint replacement surgery (arthroplasty).
Oral administration of the monosaccharide amino sugar glucosamine, which is a constituent of hyaluronic acid, has been shown in some studies to have mild to moderate efficacy in the treatment of joint conditions such as osteoarthritis. Prior oral glucosamine treatments however have been limited by the fact that glucosamine is well absorbed orally, but undergoes substantial first-pass metabolism. First-pass metabolism (also known as presystemic metabolism) is a phenomenon of drug metabolism whereby the concentration of a drug is greatly reduced as it passes through the liver before it reaches the systemic circulation. The liver metabolizes many drugs; sometimes to such an extent that only a small amount of active drug emerges from the liver to the rest of the circulatory system. The first pass through the liver greatly reduces the bioavailability of glucosamine.
Advantages of the baths, soaks, lozenges, suppositories, patches, and topical creams comprising glucosamine or a pharmaceutically acceptable salt thereof, compositions adapted therefor, and methods of treatment using the same described herein include, but are not limited to, avoiding first-pass metabolism by allowing glucosamine and other substances to be absorbed directly into the systemic circulation. Further advantages include providing new and expanded transdermal and transmucosal treatment options for patients suffering from joint conditions, including osteoarthritis.

In a particular embodiment, the time the subject is exposed to the medication or supplement is greater than 1 minute and less than 5 hours.
Many temperatures for the water in which the subject is immersed are suitable. In various embodiments, suitable temperatures include about 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, and 48 degrees Celsius, including increments therein. In some embodiments, the temperature of the water in which the subject is immersed is greater than 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, and 47 degrees Celsius. In some embodiments, the temperature of the water in which the subject is immersed is less than 47, 46, 45, 44, 43, 42, 41, 40, 39, 38, 37, 36, 35, 34, 33, 32, 31, and 30 degrees Celsius. In some embodiments, the bath or soak is cold and has a temperature of from 34 to 37 degrees Celsius. In other embodiments, the bath or soak is warm and has a temperature of from 38 to 41 degrees Celsius. In some embodiments, the bath or soak is hot and has a temperature of from 42 to 45 degrees Celsius.
In some embodiments, the temperature of the water in which the subject is immersed is greater than about 37 degrees Celsius as this increases capillary dilation and will increase potential absorption of the medication or supplement. When absorption rates at different temperatures are known, then Ab of Formula 1 in the immersion therapy equation will reflect the absorption rate at that particular temperature. In some embodiments, the subject takes a shower or otherwise rinses the skin before entering a bath or soak in order to eradicate excess skin oil which would otherwise interfere with absorption. In other embodiments, this is not a required step of immersion therapy.
In a particular embodiment, immersion therapy involves partially or completely immersing a subject's body in a glucosamine solution (e.g., a bath or soak) in order to raise the blood plasma level of glucosamine. In a further embodiment, immersion therapy with a glucosamine solution elevates blood plasma levels of glucosamine to support optimal joint function.
A wide range of amounts of glucosamine are suitably added to liquid to create a bath or soak with a wide range of suitable glucosamine concentrations. In various embodiments, suitable quantities of glucosamine for the bath or soak are about 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, 2400, 2500, 2600, 2700, 2800, 2900, 3000, 3100, 3200, 3300, 3400, 3500, 3600, 3700, 3800, 3900, 4000, 4100, 4200, 4300, 4400, 4500, 4600, 4700, 4800, 4900, and 5000 grams, including increments therein.

For example, a subject with a high BMI is optionally exposed to a higher overall quantity of glucosamine and/or a higher concentration of glucosamine in a bath or soak. Conversely, a subject with a low BMI is optionally exposed to a lower overall quantity of glucosamine and/or a lower concentration of glucosamine in a bath or soak. In other embodiments, the quantity of glucosamine is determined based on the severity of the condition or symptoms of the subject.

EXAMPLES
The following examples illustrate representative embodiments and are not meant to be limiting.
Example 1
An 84-year-old female patient with a history of right total knee replacement and several year history of severe left knee osteoarthritis presents with constant pain that limits walking (e.g., uses a cane for ambulation). The patient has undergone ultrasound-guided steroid and hyaluronic injections, acupuncture, and physical therapy with little effect. Steroid injections offered moderate pain relief ( ̃30-40% reduction) but the pain has returns after one week
The patient is given glucosamine powder with instructions to use 1 kg in a bath soak every day for three days. (Directions: Fill the bath to the point where all of the powder dissolved—soak in bath for one hour.)
One week post treatment the patient reports 50% improvement, is able to walk for twice as long, and no loner requires a cane for outdoor ambulation. Three weeks post treatment the patient reports 70-75% improvement in pain and function. Although the patient continues to use a cane for outdoor ambulation she reports experiencing days with no pain at all. Two months post treatment the patient reports persistent 70-75% improvement in symptoms. Further results are shown in FIG. 1.
Example 2
Patients diagnosed with osteoarthritis were selected for an experimental study of a glucosamine bath soak as described herein. The patients were instructed to pour 1 kilogram of glucosamine powder into a hot bath and to sit in the hot bath for one hour. Patients were instructed to keep bath water as hot as they could without making themselves “too uncomfortable” and without burning themselves. Patients were instructed to repeat for five days (one bath per day), but patient 4 only completed 4 baths.
Prior to treatment, patients were surveyed for VAS pain scores and asked to list at least four activities that they cannot perform due to osteoarthritis and pain. Results are summarized below and in FIG. 2-8 (individual VAS scores) and 10 (data for Patients 1-7).
