Decision Resources, one of the world's leading research and advisory firms focusing on pharmaceutical and health care issues, announced today that the introduction of generic forms of Claritin (Schering-Plough's loratadine) will reduce the United States antihistamine market by 15% over the next ten years. According to the new report entitled Allergic Rhinitis, the availability of over-the-counter nonsedating antihistamines will reduce the prescription drug-treated population in the U.S. from 95% of the diagnosed cases in 2001 to 80% in 2011.

"The historically lucrative allergic rhinitis market is on the verge of major transitions, particularly in the United States," said Daqing Hartwell, Director of the Immune and Inflammatory Disorders Service at Decision Resources. "On the one hand, generic substitutions and possible prescription to over-the-counter switches of major products threaten to reduce the market size for prescription drugs. On the other hand, the recently published Allergic Rhinitis and Its Impact on Asthma report endorsed by the World Health Organization (WHO) encourages early treatment of allergic rhinitis in order to prevent asthma exacerbations. This recommendation may lead to an increase in the number of patients treated with nasal corticosteroids and also encourages the development of combination therapies."

Disease Facts - Allergic Rhinitis

Allergic rhinitis is a highly attractive disease target for pharmaceutical companies because it affects nearly 150 million people in the world's seven major pharmaceutical markets (United States, France, Germany, Italy, Spain, United Kingdom, and Japan). Most people with allergic rhinitis self-medicate with nonprescription "first-generation" antihistamines and/or decongestants. According to allergy experts interviewed by Decision Resources, only 30-45% of allergic rhinitis patients are actually diagnosed with the condition by a physician. Consequently, there is a vast untapped market of allergic rhinitis sufferers who could benefit from prescription medications that either are more potent or produce fewer side effects than available over-the counter drugs.
