Allergan Receives Positive Opinion for GANFORT(R) (LUMIGAN(R)/Timolol Combination) in European Union

IRVINE, Calif.--(BUSINESS WIRE)--March 27, 2006--Allergan, Inc. (NYSE:AGN) today announced that the Committee for Medicinal Products for Human Use (CHMP) has recommended that the European Commission approve GANFORT(R), Allergan's LUMIGAN(R)/timolol combination product (bimatoprost/timolol ophthalmic solution) for the treatment of glaucoma. The CHMP opinion serves as the basis for a European Commission approval, which is expected to be finalized in the second quarter of 2006.

GANFORT(R) is indicated for reduction of intraocular pressure (IOP) in patients with open-angle glaucoma or ocular hypertension who are insufficiently responsive to topical beta-blockers or prostaglandin analogues.

"Adherence to therapy is an integral factor in the successful treatment of glaucoma and ocular hypertension. Combination therapies often reduce the number of medications required and can aid patients with compliance," said Dr. Scott Whitcup, Allergan's Executive Vice President, Research & Development. "We are very pleased to have received this positive opinion for GANFORT(R) in the European Union and to present physicians and their patients with this latest advance in combination therapy for the treatment of glaucoma, a leading cause of preventable blindness worldwide."
