Growth Hormone Releasing Hormone (GHRH) Treatment for Age-Related Sleep Disturbances

The purpose of this study is to examine the effects of giving growth hormone releasing hormone (GHRH) to treat sleep disorders in older men and in older women who are on estrogen replacement therapy (ERT). Many older men and women complain of sleep disturbances. GHRH has been used successfully to treat sleep disorders in young men and may help older men and women. 40 healthy older men and 40 healthy older women on ERT will receive either GHRH or an inactive placebo. An individual may be eligible for this study if he/she is a healthy older man or woman with sleep disturbances, and is on estrogen replacement therapy (women).
