Mucinex(R) and Delsym(R) Brands Rated Highly by Pharmacists in Pharmacy Times 2007 OTC Recommendation Survey

Adams Respiratory Therapeutics, Inc. (Nasdaq: ARxT) today announced that both Mucinex(R) (600 mg guaifenesin extended-release bi-layer tablets) and Delsym(R) (dextromethorphan polistirex) brands ranked No. 1 in their respective over-the-counter (OTC) therapeutic categories, in the recently published Pharmacy Times 2007 OTC Survey of Pharmacist Recommendations. According to Pharmacy Times, pharmacists make more than 15 million recommendations every month in the Cough and Cold category alone -- including adult and pediatric formulations.

For the second consecutive year, Mucinex achieved elite status in the Pharmacy Times OTC Master's Circle, which includes products that have earned at least 50 percent of pharmacists' recommendations in the OTC Recommendation Survey. In the adult expectorant category, Mucinex was rated No. 1, with 62.6 percent of pharmacist recommendations.

In its first year of marketing under Adams' ownership, Delsym ranked No. 1 in the Children's Cough category with 34.3 percent of pharmacist recommendations. In the adult cough category, Delsym and Mucinex ranked No. 1 and 3, with 41.4 percent and 18.1 percent of pharmacist recommendations, respectively.

Commenting on the survey results, John S. Thievon, executive vice president, sales and corporate accounts said, "We are very pleased that Mucinex maintained its No. 1 recommended brand position for the second year in a row. The strong acceptance among U.S. pharmacists demonstrates that our sales teams have a winning strategy that clearly articulates how Mucinex helps consumers get extended relief for chest congestion."

Robert D. Casale, chief operating officer, added, "Since acquiring the Delsym brand in June 2006, we have experienced tremendous success with the brand, and we are encouraged that the product is generating such a high level of pharmacist recommendations. Both Mucinex and Delsym are benefiting from a well-executed marketing strategy and these endorsements by pharmacists support our plans to further expand these product lines."
