For Immediate Release

Alcon Develops New, Once-Daily Formulation of

PATANOLÒ ophthalmic solution for the Treatment of Ocular Allergies

ForT Worth, Texas, Jan. 23 - Alcon, Inc. (NYSE: ACL) will present the results from two clinical trials involving a new, investigational once-daily formulation of the company's flagship brand PATANOL^® at the annual meeting of the Western Society of Allergy, Asthma & Immunology (WSAAI) in Hawaii this week.

The first study investigated the product's safety and efficacy up to 24 hours after dosing, while the second evaluated the safety of the drug. This new formulation of PATANOL solution is intended for the once-daily treatment of ocular allergy.

In the first clinical trial, adult subjects were given the study medication once and then exposed, after a specified interval, to an allergen that previously caused the patientsto have intense ocular allergic reactions. The study showed that up to 24 hoursafter treatment, subjects experienced a significant reduction in ocular itching and redness when compared to the placebo group.

The second clinical trial evaluated the drug's safety profile in patients aged 3 years and older who showed no signs or symptoms of allergic conjunctivitis. The subjects were given a once-daily treatment for six weeks. The study demonstrated that the new once a day formulation of PATANOL solution was safe and well tolerated in children, adolescents, adults and elderly participants. In addition, the adverse events reported by those who wore contact lenses throughout the study were similar in type to those experienced by those subjects who did not wear contacts.

Because it only needs to be instilled topically to the eye once a day, the drug does not interfere with patients' normal daily activities, which should enhance patient compliance. This benefit is especially true for young children and adults with highly active lifestyles. Alcon anticipates approval of its NDA later this year.

PATANOL solution was the first ocular allergy product to combine antihistamine and mast cell stabilizing action. In the United States, it is now the most frequently prescribed topical treatment of allergic conjunctivitis, an allergen-induced, inflammatory response characterized by intense itching, redness and tearing.

Alcon introduced the currently marketed twice-daily formulation of PATANOL solution in 1997 and currently markets the drug in over 30 countries, including the US and Canada. PATANOL solution has been approved by the European Union under the trademark OPATANOLÒ eye drops and will launch there this spring. Due to its effectiveness, comfort, and favorable safety profile, PATANOL solution has been well accepted by both patients and physicians and has become a category-leader in most markets where it has been introduced.

Alcon is the world's leading eye care company and has been dedicated to the ophthalmic industry for more than 50 years. Alcon develops, manufactures, and markets pharmaceuticals, surgical equipment and devices, contact lens solutions, and other vision care products that treat diseases, disorders, and other conditions of the eye.

PATANOL and OPATANOL ophthalmic solutions are registered trademarks of Alcon, Inc. in the US and throughout the world.
