Definitions
- the present invention relates to a novel therapeutic agent for rheumatism.
- Rheumatoid arthritis is a chronic systemic inflammatory disease involving joints, and patients with rheumatoid arthritis often have difficulty in their daily lives due to dysfunction of the joints.
- Salicylic acid has long been known as a therapeutic agent for rheumatism, but currently widely used drugs include sodium gold thiomalate, penicillamine, olananofin, lonzarritni sodium, psiramine, methotrexate (MTX).
- MTX methotrexate
- An object of the present invention is to provide a new therapeutic agent for rheumatism which has high side effects, high safety, and excellent therapeutic effects.
- the present inventors have found that N-substitution of 5-fluoroperacil, which produces 5-fluoroperacil in the form of 5-fluorouracil or 5-fluorouracil which has been conventionally used as an antitumor agent.
- the present inventors have found that the body shows excellent medicinal effects as a therapeutic drug for rheumatism, and have led to the present invention.
- the present invention can provide a therapeutic agent for rheumatism containing an N-substituted 5-fluoroperacil, which produces lauracil, as an active ingredient.
- 5-Fluororlausyl used as a medicinal ingredient in the present invention is represented by the following structural formula.
- Examples of the substance that produces 5-fluoroperacil in vivo include ⁇ -substituted 5-fluoroperacil, typical examples of which include tegafur and doxyfluridine shown below.
- the 5-fluorouracil or its ⁇ -substituted product is used as an antitumor
- a modulator m 0 du 1 ator
- Such substances include methotrexate, leucovorin and the like, and it is preferable to use peracyl represented by the following formula, and the amount of peracyl is 5-fluorouracil or its N-substituted 1 About 4 moles per mole.
- the therapeutic agent for rheumatism of the present invention is administered by a conventional administration method such as oral or injection. In this case, the daily dose is 300 to 1200 mg, and it is preferable to administer this amount in 3 to 4 divided doses.
- the remedy for rheumatism of the present invention is a completely new type different from conventional products, and exhibits high drug efficacy and specificity for rheumatoid arthritis without causing serious side effects.
- Therapeutic agent A (Tegafur: 15 mg / kg, Peracil: 33.6 mg / kg) or Therapeutic agent B (Tegafur: l.Smg / kg) was dissolved or suspended in a 5% gum arabic solution and orally administered. After 4 hours, the transferability of each therapeutic agent to tissues (plasma, feet inoculated with bovine dairy bacteria, feet not inoculated with bovine dairy bacteria) was measured by an ordinary method.
- both therapeutic agents A and B showed good transferability to tissues. Tegafur concentration in the tissue was not significantly different between the treatment with A and the treatment with D, but the tissue concentration of 5-fluorouracil (5-FU) A large difference was observed, and it was confirmed that the 5-FU concentration was larger in the therapeutic agent A administration group. This suggests that the metabolism of 5-FU, the active form, was suppressed in the inflammatory site near rheumatism by using peracil together.
- RA rheumatoid arthritis
- ARA American College of Rheumatology
- this test At the time of treatment, the patient fully explained the purpose, content, duration, expected clinical effects, and expected side effects of the study to the patient, and obtained consent to participate in this study.
- Treatment A The treatment period of Treatment A was 6 weeks or longer, and one capsule of Treatment A (containing 10 Omg of Tegafur and 224 mg of Peracil) was taken once a day and taken three times a day after meals.
- Non-steroidal anti-inflammatory drugs were not changed during the treatment with therapeutic agent B, and joint injection of new immunosuppressants, immunomodulators, and corticosteroids was not allowed.
- the overall safety level is 4 levels of overall safety, taking into account the side effects during the administration of therapeutic agent A and clinical test results (safe, almost safe, unsafe, unsafe) Was evaluated.
- the degree of usefulness was determined based on a comprehensive assessment of overall improvement and overall safety, and was evaluated in 7 stages (very useful, useful, somewhat useful, neither good, slightly unfavorable, unfavorable, extremely unfavorable) .
- Tables 1 and 2 show the clinical effects of the 6 cases 12 weeks after administration of therapeutic agent A.
- Table 1 shows the transition of various parameters before and after the administration of therapeutic agent A
- Table 2 shows the transition of each evaluation item before and after the administration of therapeutic agent A.
- L ansbury activity index [Morning stiffness duration (min) Grip strength (mmH g), blood sedimentation value (mm / hr), and activity function) were 63.2 ⁇ 30.3% before administration, and 29.4 ⁇ 13.7% after administration. And the rate of change was 53.5%.
- CRP was 13.1 ⁇ 10.2 mg / d1 before administration, and 4.0 ⁇ 2.2 mg / d1 after administration, a decrease of 69.5% in the variation rate.
- IgG immunoglobulins
- IgA is 268.2 ⁇ 4 8.OmgZd l 2 27.0 ⁇ 51.5 mg / d1 (variation 15.4%)
- IgM is 194.2 ⁇ 64 lmgZd l 1 33.2 ⁇ 57.4 mg Zd l (variation rate 31.4%) was shown.
- Short-term treatment effects over 16 weeks include stiffness in the morning, pain in joints * tenderness and swelling, comprehensive evaluation of patients, comprehensive evaluation of physicians; laboratory findings also show increased red blood, CRP, RAH A aggregation
- immunoglobulin especially IgM
- improvement of 50% or more in Lansburyindex was observed around 8 to 10 weeks, and it was confirmed that this drug showed a relatively strong antirheumatic effect.
