A large clinical trial of a new osteoporosis drug found that it stimulates bone growth and prevents fractures at least as well as the only other such drug on the market. The new drug, expected to win approval from federal regulators, would offer another much-needed treatment for some of the 10 million Americans, 80 percent of them women, who have a disease that weakens bones and often leads to years of pain, disability and early death.
Experts agree that new drugs are urgently needed for this debilitating disease. People with osteoporosis have bones that are fragile and break easily. Bone is naturally lost with age. But osteoporosis is an extreme, abnormal bone loss that can cause devastating fractures, particularly of the spine and hip. Yet most with osteoporosis do not take medications to prevent fractures, according to the National Osteoporosis Foundation.
