Japanese Patent JPH07215849
Kind Code:

PURPOSE: To obtain an anti-osteoporosis agent having a suppressive function against osteoclast formation and excellent in activity and safety by compounding a polyisoprenoide derivative as an effective component.

CONSTITUTION: This agent contains a compound of formula I (R is OH, formula II or formula III; waved line is an E-type or a Z-type double bond), e.g. (2E,6E,10 E)-3,7,11,15-tetramethyl-2,6,10,14-hexadecatetraene-1-ol. The agent may be formulated into a preparation, e.g. a powder, a particle, a granule, a tablet, a coated tablet, a capsule, an ointment, a plaster or an injection. A daily dose for an adult is 100-3000mg. The compound of formula I has the suppressive activity against osteoclast formation in a coexistent system of an osteoblast and a spleen cell. In osteoporosis, the balance between bone resorption and osteogenesis is destroyed and the bone resorption is accelerated. As a result, the amount of bone is decreased, bones become fragile and pain is accompanied. Osteoporosis frequently occurs especially in a postmenopausal woman and its treatment continues for a long time. Therefore, the danger of the occurrence of side effects characteristic to female sex hormones is concerned and so as drug is required to have high safety.
