| NCT01384591 | Pilot Study of Losartan and N-acetylcysteine as Inhibitors of Muscle Oxidative Stress in Elderly | Completed | Lantheus Medical Imaging | Phase 1/Phase 2 | 2011-07-01 | The general hypothesis is that elderly have diminished nutritive flow to skeletal muscle and impaired capacity for building of muscles. In aging populations, this decreased ability to build muscles may represent a tipping point in the progression towards chronic physical frailty and disability. The goal is to examine whether novel pharmacologic therapies can improve nutritive blood flow to the muscles and muscle building in the elderly. The purpose of this study is 1) to determine if losartan administration will enhance the building of muscles via proteins and suppress muscle breakdown 2) to determine if N-acetylcysteine (NAC) will enhance blood flow to muscles and the building of muscles via proteins. The investigators will study community dwelling, healthy older men and women (60-85 years). Subjects will be randomized to one of three groups: Experimental Group 1: Placebo losartan and placebo N-acetylcysteine (NAC). Experimental Group 2: losartan (25mg/dose) and placebo N-acetylcysteine (NAC). Experimental Group 3: N-acetylcysteine (NAC) (50 mg/kg/dose) and placebo Subjects will admit the night before and get their first dose of NAC/ losartan/ placebo with dinner. Subjects will be fasted after 10 pm. The next morning at 6 am blood samples will be taken and leg blood flow (LBF) will be measured. Subjects will receive their second dose of NAC/ losartan/ placebo. As from 6 am every hour blood will be drawn until 1 pm. At 8am, the second biopsy is taken and LFB and CEU will be measured. At 11am they get their third dose of NAC/ losartan/ placebo together with leucine (oral) and again a muscle biopsy is taken and LBF is measured. Leucine is anabolic to skeletal muscle of elderly and so the investigators will use it to stimulate muscle building. |
