Definitions
- the present invention relates to a medicament containing, as an active ingredient, natural calcitonin or a calcitonin derivative having a prophylactic effect against reflex sympathetic dystrophy that develops after a stroke.
- Reflex Sympathetic Dystrophy is mainly a trauma to the extremities characterized by clinical symptoms such as pain, hyperalgesia, movement disorders, and autonomic disorders.
- ⁇ Power a disease that develops with surgical invasion, often develops with vascular disorders in the trunk, such as stroke and myocardial infarction.
- RSD after stroke or myocardial infarction often develops as shoulder-hand syndrome (Non-patent Document 1).
- Non-patent Document 1 Painful movement limitation in the upper limb is not only a significant obstacle to rehabilitation to overcome the paralysis associated with stroke and myocardial infarction, but also the quality of life (QOL) and ADL (Activities of Daily Living). ) Is also seriously affected (Non-Patent Document 2).
- Non-patent document 1 Non-patent document 3
- Non-patent document 4 To do.
- the disease is resistant to treatment and often leaves serious aftereffects.
- it is easy to relapse (Non-patent Document 1).
- Non-patent Documents 2 and 5 Various treatment methods for RSD and shoulder-hand syndrome have been reported so far. No systematic treatment methods have yet been established (Non-patent Documents 2 and 5). In clinical settings, for example, low-dose steroids are used for the purpose of avoiding various side effects (susceptibility to infection, decreased bone density, abnormal glucose metabolism, gastric ulcer, etc.) caused by long-term steroid use. Use is limited for a short period of time, and long-term management of the disease is considered difficult. Nerve block that repeatedly performs local anesthesia for the sympathetic nerve is a treatment method that is also favored.
- Vitamin C's initial preventive effect (non-patent document 6) and natural calcitonin recurrence preventive effect (non-patent document 7 and non-patent document 8) against RSD that develops due to trauma and surgical invasion
- no drug has been reported that has demonstrated a safe and sufficient preventive effect for RSD that develops due to stroke, except for steroids, which are difficult for long-term continuous administration.
- the only report was that the post-stroke RSD was suppressed to 8 to 18.5% by S and the load restriction on the shoulders and paralyzed limbs (Non-patent document 9, Non-patent document 10). In light of the seriousness of the disease, it is still not enough.
- Natural calcitonin is a polypeptide consisting of 32 amino acids secreted from thyroid cells in mammals. Since natural calcitonin or calcitonin derivatives act on osteoclasts to suppress bone resorption and reduce blood calcium concentration, it is clinically useful as a therapeutic and / or prophylactic agent for high-strength lucumemia and osteoporosis. Has been used. In addition, natural calcitonin or calcitonin derivatives are widely known to have analgesic effects on certain types of pain such as low back pain associated with osteoporosis, cancer pain, inflammatory pain, and have already developed. A therapeutic effect has also been reported for RSD (Non-Patent Documents 11 and 12).
