INSPIRE REPORTS THIRD QUARTER 2006 FINANCIAL RESULTS

- Third Quarter 2006 Revenue Increases 48% from Third Quarter 2005 -

DURHAM, NC – November 7, 2006 – Inspire Pharmaceuticals, Inc. (NASDAQ: ISPH) today reported financial results for the third quarter ended September 30, 2006.

Total revenue for the third quarter of 2006 was $9.7 million, which was generated from co-promotion activities, compared to $6.6 million for the third quarter of 2005. Co-promotion revenue from net sales of Elestat^® (epinastine HCl ophthalmic solution) 0.05% was $5.4 million, an increase of 20% compared to $4.5 million recognized in the third quarter of 2005. Co-promotion revenue on net sales of Restasis^® (cyclosporine ophthalmic emulsion) 0.05% for the third quarter of 2006 was $4.3 million, an increase of 109% compared to $2.1 million recognized in the third quarter of 2005. The increases in third quarter 2006 co-promotion revenues, as compared to 2005, were related to the continued patient and physician acceptance and usage of Elestat and Restasis in the United States, a continued increase in the allergic conjunctivitis products market in which Inspire competes and an increase in Inspire’s entitled percentage of net sales of Restasis effective in April 2006.

Total revenue for the nine months ended September 30, 2006 was $28.6 million, as compared to $18.0 million for the same 2005 period. Co-promotion revenues were $27.4 million, an increase of approximately $9.4 million compared to the same period in 2005. In addition, in the first quarter of 2006, the Company recognized $1.25 million in development milestone revenue received pursuant to a collaborative research agreement with Santen Pharmaceutical Co., Ltd. related to Santen’s completion of Phase 2 development of diquafosol tetrasodium for dry eye disease in Japan.

Operating expenses for the third quarter of 2006 totaled $18.1 million, as compared to $14.4 million for the same period in 2005. All categories of operating expenses increased in the third quarter of 2006, as compared to 2005, with research and development expenses increasing $1.5 million, selling and marketing increasing $1.1 million and general and administrative expenses increasing $1.0 million. Increased research and development expenses were attributable to

increased costs for advancing the Company’s seasonal allergic rhinitis and glaucoma programs, as well as increased costs associated with the cardiovascular program prior to the Company terminating its Phase 2 clinical trial in August 2006. Increased selling and marketing costs were due to an overall increase in promotional activities and costs associated with the Company’s sales force. Increased general and administrative expenses were due to increased legal and administrative costs associated with the ongoing stockholder litigation and U.S. Securities and Exchange Commission (SEC) investigation, as well as increased personnel costs, partially due to implementation of Statement of Financial Accounting Standards No. 123(R). Operating expenses for the nine months ended September 30, 2006 were $58.7 million, as compared to $45.8 million for the same period in 2005.

Effective January 1, 2006, the Company adopted the fair value recognition provisions of Statement of Financial Accounting Standards No. 123 (R), “Share-Based Payment”. The Company recorded approximately $417,000 and $1.1 million of stock-based compensation expense, related to stock options and restricted stock units, in its operating expenses for the third quarter and nine months ended September 30, 2006, respectively.

For the quarter ended September 30, 2006, the Company reported a net loss of $7.2 million, or ($0.17) per share, as compared to a net loss of $6.8 million, or ($0.16) per share, for the same period in 2005. The net loss for the nine months ended September 30, 2006 was $26.6 million, or ($0.63) per share, as compared to a net loss of $24.8 million, or ($0.59) per share for the same period in 2005. Cash, cash equivalents and investments totaled $95.6 million at September 30, 2006, reflecting a $26.7 million utilization of cash, cash equivalents and investments during the first nine months of 2006.

Based upon the current results and trends and the recent completion of the FAES Farma in-licensing agreement in October 2006, which requires the Company to pay an upfront license fee of $7 million, the Company has adjusted its 2006 operating guidance to aggregate revenue of $35-$39 million and operating expenses of $84-$89 million, which includes approximately $2 million of stock-based compensation expense.

Christy L. Shaffer, Ph.D., President and CEO of Inspire, stated, “Our commercial team continued to deliver excellent performance, driving nearly 50% growth in revenues from Elestat and Restasis. We are looking forward to leveraging our commercial infrastructure with bilastine, the late-stage novel oral antihistamine compound that we recently added to our allergy franchise through an in-licensing collaboration with FAES Farma. We also made progress in our other allergy program with the filing of an Investigational New Drug (IND) application and initiation of Phase 2 testing of epinastine nasal spray.”
