There is no known cure for ALS. The medication and treatment prescribed for this disease centers on prolonging the duration and quality of life for ALS patients. There are numerous drugs and supportive therapies such as speech pathology or occupational therapy, prescribed to help ALS patients cope with the different symptoms they will experience. A Food and Drug Administration (FDA) approved drug called Rilutek © has been shown to prolong the survival rate by an average of three months. Rilutek © is used to slow down the loss of muscle strength, and is more effective in bulbar-onset ALS.
