Which ALS treatment is the most effective?

Several medications have been approved by the U.S. Food and Drug Administration  as amyotrophic lateral sclerosis (ALS) treatments. These therapies have been shown to slow the progression of ALS in clinical trials, but studies have generally not compared them against each other. Furthermore, each patient may respond differently to each therapy; as such, it’s impossible to say whether one medicine or the other is more effective for an individual patient.
