OSTEOGENESIS PROMOTER AND OSTEOPOROSIS REMEDY

摘要

An osteogenesis promoter and/or an osteoporosis remedy containing an androgen derivative represented by general formula (1) or a salt thereof as the active ingredient. In said formula (1), the broken lines indicate that the bonds containing the same represent each either a single or a double bond. The compound (1) activates osteoblasts, promotes osteogenesis and increases bone quantity, and hence it is used for treating a morbid condition of lowered osteogenesis due to aging, immobilization, administration of glucocorticoids, and so forth. Further it can increase bone quantity by the osteogenesis promoter effect thereof, so that it is useful for treating osteoporosis accompanying the above morbid condition or occurring after ovariectomy or menopause.
