WASHINGTON (AP) - concerns of security with the popular birth control pill as yaz increased federal Thursday that scientists of Health reported that the drug from Bayer and other newer birth control treatment appear to increase the risk of dangerous blood clots more older drugs.
A new study published by the Food and Drug Administration reviewed the medical history over 800,000 women U.S. takes different forms of control of births between 2001 and 2007. On average, women taking Yaz had 75% more likely to end up with a blood clot than women older birth control medications.
YAZ contains estrogen with a synthetic hormone of next generation called drospirenone, who is known to increase the level of potassium in the blood. FDA compared the medical records of women taking the drug with those who take the old drug levonorgestrel.YAZ, Yasmin and related pills containing drospirenone of were free of second-best-selling Bayer to $ 1.6 billion in global sales last year.
In 2009, the FDA has taken an unusual step order Bayer to run corrective on Yaz TV advertisements, stating that the ability of drugs exaggerated the drugmaker marketing campaign to prevent acne and premenstrual syndrome.Bayer Healthcare, a division of the German conglomerate, it says "currently assessing this publication and cannot comment on at this time."
The Agency also reported complications higher in women using the Ortho Evra of Johnson & Johnson and ring patch vaginal Nuvaring of Merck & Co. Inc. These drugs combine estrogen, which is present in all birth control pills, with two other synthetic hormones in the last decade.The FDA said it has not reached a final conclusion on the safety of the drugs but will hold a meeting with scientific advisors on 8 December.
The consumer safety advocates have criticized the Agency of the latest and most expensive birth control drug approval when cheaper, generic medicines with established security records are widely available."At some point we must ask why the FDA continues to approve drugs that are less safe and have no advantage over drugs already on the market," said Dr. Diana Zuckerman, President of the National Centre for women and families, a group of consumers for women's health issues. "With all these different birth control options, why take the more expensive that can kill you?"
Recent studies have reached different conclusions about the risks of contraceptive pills more recent.A study published earlier this week on more than 1 million Danish women found that women taking Yaz and other newer drugs have twice the risk of blood clots as women taking the hormone levonorgestrel older. The findings published Tuesday in the British Medical Journal.
However, two studies published in 2007, conducted as part of the regulators FDA postmarketing requirements or European, have not found any difference in clotting between comparable groups.Pills of birth control containing drospirenone include Yaz, Yasmin, Bayer's Beyaz, Safyral; Sandoz Syeda and Loryna; as well as Ocella Barr, Watson Pharmaceuticals Zarah and Loryna of Teva Pharmaceuticals laboratories.
