Test example 1
With regard to the preparations of Test Tablets 1 and 2 and Examples 8 and 9 shown in Table 1, the joint pain improvement effect was examined for 10 persons each having knee joint pain in daily life due to deformation of the knee joint. In addition, the test tablet was prepared according to the formulation of Example 1 except changing the usage-amount of an active ingredient.

  The test was performed by taking the test tablet 3 times a day for 3 weeks under the condition of 3 tablets each time and comparing it with the joint pain before taking. The evaluation was performed by scoring the degree of joint pain when walking, climbing stairs, standing up from a chair, and sitting upright. The degree of joint pain was scored according to the following criteria.

[Pain when walking]
Not painful: 0 points, painful when walking long distance: 1 point, painful even if walking short distance: 2 points [pain when going up and down stairs]
Can climb up and down easily: 0 points, can easily climb up and down with handrails: 1 point, step up and down step by step: 2 points [pain when getting up from a chair]
Not painful: 0 points, painful if not supported by hand: 1 point, painful if held by hand: 2 points [pain when sitting upright]
Can sit straight: 0 points, cannot sit down but can sit sideways: 1 point, can not sit sideways: 2 points For each item, the effect was evaluated by the difference of the total score of 10 people before and after taking. That is, the larger the difference Δ between the total points, the higher the improvement effect. The results are shown in Table 2.

  Furthermore, the degree of joint pain in daily life was evaluated by VAS (Visual Analogue Scale). That is, as an evaluation method, when the left end of the 10 cm scale is “no pain at all” 0 points and the right end is “the highest pain that can be imagined” 100 points, how much the degree of pain perceived corresponds to, The test subject was pointed at one point on the scale, and the score of the indicated scale was examined. And the effect was evaluated by the difference of the total score of 10 people before and after taking.

  As is clear from the above table, as a result of examining the improvement effect on joint pain by VAS and the degree of joint pain during walking, stair climbing, standing up from a chair, sitting upright, and daily activities of the four items, Compared to a preparation containing sodium chondroitin sulfate and glucosamine hydrochloride, the preparation of the present invention further containing vitamin B1 improved the joint pain in any of the items, and a high effect was recognized. Moreover, it was shown that the limitation of the range of motion of the joint was eased from the improvement of the joint pain during the daily life movement, and the present invention was able to further relax the limitation of the range of motion of the joint.

  Furthermore, even if it compared with the formulation which mix | blended vitamin B1 and chondroitin sodium sulfate, the formulation of this invention which further mix | blended glucosamine recognized the high effect.

Therefore, it was shown that the preparation of the present invention is useful for the treatment or prevention of diseases such as osteoarthritis and arthritis that cause joint pain.
