IMPAX Announces the Launch of IMPAX Pharmaceuticals; Company's Branded Products Division

July 11, 2006

HAYWARD, Calif.--(BUSINESS WIRE)--July 11, 2006--IMPAX Laboratories, Inc. (OTC:IPXL) today announced that consistent with its previously stated strategic intent and timeline, it has launched IMPAX Pharmaceuticals as the Company's branded products division. IMPAX Pharmaceuticals has deployed its specialty sales force of 66 representatives through a contract sales arrangement with a third party. This organization is being managed by a dedicated IMPAX management team experienced in the sales and marketing of branded pharmaceutical products and will promote Carbatrol(R) (carbamazepine extended release capsules), a product of Shire Plc, for the treatment of epilepsy and trigeminal neuralgia. Carbatrol(R) had U.S. gross sales of $77 million for the 12 months ended May 31, 2006, according to Wolters Kluwer Health.

The potential target market for Carbatrol(R) is nearly 8,300 neurologists in the U.S. and overlaps with IMPAX's target market for its own neurology focused products. IMPAX Laboratories has several products at various stages of development including Vadova(TM) (carbidopa and levodopa), which is under review by the U.S. Food and Drug Administration. The establishment of this division is expected to allow IMPAX to achieve synergies in overall sales and marketing costs.

Commenting on the launch, Larry Hsu, Ph.D., IMPAX's president, stated, "We are very pleased to have achieved this milestone in the continued development of IMPAX and to establish our company's name within the neurology marketplace. The launch of this division is consistent with our corporate growth and strategic objectives and positions IMPAX well to capitalize on its established relationships to benefit the introduction of its own future products."
