A few potential blockbusters won approval during the year, but some of the most highly anticipated new products got delayed into next year or beyond. That partly reflects a tougher environment at the FDA, with regulators stepping up their scrutiny of safety issues in drugs for obesity, diabetes and other conditions.
According to monthly drug-approval reports on the FDA's website, 21 new drugs were approved in 2010, down from 25 in 2009 and 24 in 2008, but higher from a recent low of 18 in 2007.
