Definitions
- the present invention relates to a composition for treating osteoporosis according to muscle loss and bone density decrease, and more particularly, to a composition for treating osteoporosis through a mechanism for promoting muscle fiber formation or inhibiting differentiation of osteoclasts containing cycloLphenylalanylelproline dipeptide. it is about
- the body fat content increases, the solid content and water decrease, and in particular, the calcium in the bones is lost, and the bone mass decreases, which leads to a decrease in bone density.
- the cartilage tissue becomes thinner and the elasticity is weakened, which causes arthritis, and the volume of the voluntary muscle is reduced, resulting in decreased exercise capacity.
- Hip fracture refers to a fracture around the hip joint and occurs mainly in the elderly over 70 years of age with severe osteoporosis. Falls are the main cause, and there are various causes that contribute to it, but weakness in muscle strength and a decrease in bone density are the main causes.
- Osteoporosis and senile sarcopenia are of increasing interest with the aging of the population, but no solution has been found yet. Specifically, hormones, bisphosphonates, RANKL antibodies, and PTH peptides are used as the treatment for osteoporosis, but there are limitations on the subject and period of use, and side effects have been reported. In addition, it is reported that there is also a clinical need for a drug with a good feeling of use due to the low compliance with existing drugs. In addition, in order to increase muscle mass, biologic drugs targeting myostatin and activin receptor, which decrease muscle, are being developed, but problems of relatively low efficacy and side effects have been reported.
