英文原文：FDA Approves Sanofi’s Nasacort® Allergy 24HR for Over-the-Counter Use 

- Nasal Spray Treats Adults and Children with Seasonal and Year-Round Nasal Allergies - 

Paris, France, October 11, 2013 - Sanofi (EURONEXT: SAN and NYSE: SNY) announced today that the U.S. Food and Drug Administration (FDA) approved Nasacort® Allergy 24HR nasal spray as an over-the-counter (OTC) treatment for seasonal and year-round nasal allergies in adults and children 2 years of age and older. Nasacort is the first and only medicine in its class to be available without a prescription and will be marketed by Sanofi’s consumer healthcare division in the United States, Chattem, Inc. 

“We believe there is significant value in making certain types of medicines, like Nasacort, directly available to consumers,” said Anne Whitaker, President, North America Pharmaceuticals, Sanofi US. “Allergy sufferers will benefit from having an additional treatment option and it is a strong addition to our existing consumer healthcare portfolio.” 

Up to 60 million Americans suffer from seasonal and year-round nasal allergies annually. This can have a major disruption to the quality of life of both adults and children, interfering with sleep, outdoor activities, and for children their performance at school. Nasacort and nasal sprays in the same medication class are considered the most effective treatment for hay fever and other upper respiratory allergies. 

“By adding Nasacort to Chattem’s growing consumer healthcare portfolio, we are expanding our successful OTC allergy offering that includes the Allegra family of products,” said Zan Guerry, Chief Executive Officer, Chattem. 

Nasacort is the only single active ingredient OTC medicine that relieves the full range of nasal allergy symptoms, including nasal congestion, for 24 hours with a single daily dose.

The FDA approval of Nasacort Allergy 24HR as an OTC treatment was based on data submitted from 13 placebo-controlled efficacy studies, and safety information from 43 clinical studies, as well as information from 16 years of post-marketing surveillance data for Nasacort AQ. 

Chattem anticipates that Nasacort will be available in Spring 2014.
