However, after piecing together information from over 16,000 pages of clinical trial data and documents used in the process of licensing oseltamivir (Tamiflu) by national authorities, a team of researchers has raised critical questions about how well the drug works and about its reported safety profile. The new analysis shows inconsistencies with published reports, and describes possible under-reporting of drug-related side-effects in some published trial reports. While the drug did reduce the time to first alleviation of symptoms by an average of 21 hours, it did not reduce the number of people who went on to need hospital treatment. Results from the reanalysis of data also raise questions about how the drug works as an influenza virus inhibitor. http://medicalxpress.com/news/2012-01-uncertainties-anti-influenza-drug.html Medications Wed, 18 Jan 2012 04:00:03 EST news246081179 Your risk of heart attack may increase during the days and weeks after the death of a close loved one, according to research reported in Circulation: Journal of the American Heart Association. http://medicalxpress.com/news/2012-01-grief-linked-higher-heart.html Cardiology Mon, 09 Jan 2012 16:00:02 EST news245326451
