Amino Acid Therapy for Hot Flashes in Postmenopausal Women
The purpose of this study is to determine the safety, tolerability, and effectiveness of the amino acid L-isoleucine in the treatment of hot flashes in postmenopausal women.
Hot flashes affect approximately 75% of postmenopausal women. Although hormone replacement therapy (HRT) is highly effective in reducing hot flashes, long-term HRT is associated with increased rates of breast cancer and heart disease. Safe, effective, and well-tolerated hot flash therapies are needed. The amino acids L-methionine and L-isoleucine have produced reductions in hot flash frequency. However, long-term L-methionine therapy may increase cardiovascular risks. This study will evaluate the short-term effects of L-isoleucine therapy. Data from this study will be used to conduct long-term studies in the future.
Participants in this study will be randomly assigned to receive one of two different L-isoleucine doses for 2 weeks. Clinic visits will be made at baseline, Week 1, and Week 10. Participants will record the frequency and severity of their hot flashes in a diary.
Allocation: Randomized, Control: Uncontrolled, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Primary Purpose: Treatment

A type of anxiety disorder characterized by unexpected panic attacks that last minutes or, rarely, hours. Panic attacks begin with intense apprehension, fear or terror and, often, a feeling of impending doom. Symptoms experienced during a panic attack include dyspnea or sensations of being smothered; dizziness, loss of balance or faintness; choking sensations; palpitations or accelerated heart rate; shakiness; sweating; nausea or other form of abdominal distress; depersonalization or derealization; paresthesias; hot flashes or chills; chest discomfort or pain; fear of dying and fear of not being in control of oneself or going crazy. Agoraphobia may also develop. Similar to other anxiety disorders, it may be inherited as an autosomal dominant trait.
