Tiazac

TORONTO -- Biovail Corporation (NYSE:BVF)(TSX:BVF) announced today that a United States District Judge for the District of Columbia has granted Biovail's motions for summary judgment, thereby dismissing complaints in two related putative class-action cases asserting antitrust claims by purchasers of Biovail's Tiazac(R) product. E[acute accent]The complaints, launched in 2001 and 2003, alleged that Biovail's listing with the U.S. Food and Drug Administration (FDA) of a patent for Tiazac(R) improperly delayed the entry of a competing generic product. Plaintiffs further alleged that the delay in entry of a generic product into the market caused them to pay a premium to purchase Biovail's brand-name product. E[acute accent]In its summary judgment motion, Biovail contended that the reason why the owner of generic Tiazac(R) had not marketed its product on a timely basis was due to its inability to obtain final FDA approval, rather than through any action or omission on the part of Biovail. E[acute accent]In granting Biovail's motions for summary judgment, the Court agreed with Biovail's position that, in light of the evidence and facts pleaded, the plaintiffs had been unable to prove that they had suffered any damages for which Biovail could be responsible.

E[acute accent]About Tiazac(R)

E[acute accent]Tiazac(R) (diltiazem) belongs to a classification of drugs known as calcium channel blockers currently indicated for the treatment of hypertension and angina.

Widening of the coronary arteries also increases the amount of blood reaching the heart, which can reduce the symptoms of angina.
