Varenicline - History

History

Varenicline was discovered at Pfizer through the research aimed at modifying the structure of cytisine.

Varenicline received a "priority review" by the U.S. Food and Drug Administration (FDA) in February 2006, shortening the usual 10-month review period to 6 months because of its demonstrated effectiveness in clinical trials and perceived lack of safety issues. The agency's approval of the drug came on May 11, 2006. August 1, 2006, varenicline was made available for sale in the United States and on September 29, 2006, was approved for sale in the European Union.

Famous quotes containing the word history:

    All history becomes subjective; in other words there is properly no history, only biography.
    Ralph Waldo Emerson (1803–1882)

    History has neither the venerableness of antiquity, nor the freshness of the modern. It does as if it would go to the beginning of things, which natural history might with reason assume to do; but consider the Universal History, and then tell us,—when did burdock and plantain sprout first?
    Henry David Thoreau (1817–1862)

    I am ashamed to see what a shallow village tale our so-called History is. How many times must we say Rome, and Paris, and Constantinople! What does Rome know of rat and lizard? What are Olympiads and Consulates to these neighboring systems of being? Nay, what food or experience or succor have they for the Esquimaux seal-hunter, or the Kanaka in his canoe, for the fisherman, the stevedore, the porter?
    Ralph Waldo Emerson (1803–1882)
