Preliminary research indicates that use of nitroglycerin ointment among postmenopausal women for 2 years was associated with a modest increase in bone mineral density and decrease in bone resorption (loss), according to a study in the February 23 issue of JAMA.
"The number of osteoporotic fractures is increasing worldwide as populations age. An inexpensive and widely available treatment may help limit this increase," the authors write. "Nitroglycerin stimulates bone formation and inhibits bone resorption, is inexpensive, and is widely available. Its effects on bone density, bone structure, and bone strength are unknown." Nitroglycerin is used medically as a vasodilator (a drug that causes dilation of blood vessels) to treat heart conditions, such as angina and chronic heart failure.
