Definitions
- the present invention relates to a therapeutic agent for osteoporosis containing a certain triazepine compound as an active ingredient, a novel triazepine compound, and an intermediate compound useful for producing such a triazepine compound, which has an excellent bone resorption inhibiting action.
- Osteoporosis is a syndrome that refers to a condition in which bone mass per unit volume is abnormally reduced without changing the chemical composition of the bone itself (the ratio between organic and inorganic substances).
- the depletion of calcium and phosphorus is its physiological feature. Since the loss of bone as the disease »is accompanied by the loss of bone mass due to physiological aging, the definition of bone loss is more pronounced than that due to physiological aging, and lower back pain It can be said that the patient had s bed symptoms such as pathological fracture and vertebral deformity.
- Osteoporosis increases with age and usually affects the spine, causing low back pain and short stature. Especially in advanced cases, the long bones are also affected, and sometimes fractures may occur. It is said that the major cause of the great tendon fracture in the elderly is senile osteoporosis.
