Biovail Updates Status of NDA for Tramadol ER

TORONTO--(CCNMatthews - Mar 30, 2005) -

Biovail Corporation (NYSE:BVF) (TSX:BVF) today announced that it has
received comments from the United States Food and Drug Administration
(FDA) with regard to its New Drug Application (NDA) for Tramadol ER, an
extended-release, once-daily formulation of tramadol hydrochloride.

The FDA has acknowledged that Biovail's Complete Response to the
Tramadol ER Approvable Letter is a Class 2 response, which is therefore
subject to a six-month review. The FDA has also advised that, upon
preliminary review, it is of the opinion that additional clinical trial
data will be required. Biovail's view is that the clinical data
contained within the original NDA and the March 2005 Complete Response
fully support 505(b)(2) filing requirements, and the Company is
considering a number of options. Biovail expects to meet with the FDA to
discuss these options promptly. In the meantime, however, Biovail will
immediately undertake a clinical program to address the FDA's comments.
Biovail anticipates the submission of new clinical data in late 2005 or
early 2006. Biovail believes that a new six-month review period would
then be initiated.

Biovail's original application was submitted December 31, 2003 under
provisions of Section 505(b)(2) of the Food, Drug and Cosmetic Act. The
application included clinical and safety data obtained from four
original adequate and well-controlled trials involving more than 3,000
patients who received doses of up to 400mg of Tramadol ER once daily.
The application also included 12 definitive and five supportive
pharmacokinetic studies which demonstrated that once-daily dosing of
Tramadol ER delivers the equivalent amount of drug as Ultram®
(tramadol hydrochloride tablets) given three times (TID) or four times
(QID) per day.

In October 2004, Biovail's NDA for Tramadol ER received an Approvable
Letter from the FDA. In March 2005, Biovail submitted a Complete
Response to the FDA, which included a significant amount of statistical
analyses, but no new clinical data. The response also addressed other
items raised in the Approvable Letter, including discontinuation rates
of clinical-trial participants (dropouts), which are common in pain
trials, and previously well documented in studies involving tramadol.
