A new drug appears to be safe and effective so far in treating influenza symptoms, according to the results from clinical trials. Researchers analyzed the data from phase 2 and phase 3 placebo-controlled clinical trials and found that the single dose treatment worked when given within 48 hour after the symptoms appeared.
In the two trials, the researchers tested the injectable drug, peramivir on a total of 427 adults. The participants were instructed to report the severity of their flu-like symptoms on a four-point scale over the course of two weeks. They also reported their temperatures.
