FDA committee rejects Solvay's tedisamil

An FDA expert panel has unanimously turned thumbs down on Solvay's tedisamil for atrial fibrillation. The experts said they would need more and better data before they could change their decision. Solvay says it will continue to work with regulators. The key problem, says the panel, is that the trial data indicates only a narrow dosage range that could be safe and effective. Serious side effects were noted for the high dosage and lower doses were less effective in treating the condition.
