Exhibit 99.1 [SANTARUS, INC. LOGO] COMPANY CONTACT: INVESTOR CONTACT: Debra P. Crawford Lippert/Heilshorn & Associates, Inc. Chief Financial Officer Jody Cain (jcain@lhai.com) (858) 314-5708 Mike Pollock (mpollock@lhai.com) (310) 691-7100 www.lhai.com FOR IMMEDIATE RELEASE SANTARUS REPORTS FIRST QUARTER FINANCIAL RESULTS CONFERENCE CALL TO BEGIN AT 4:30 P.M. EASTERN TIME TODAY SAN DIEGO (MAY 12, 2004) - Santarus, Inc. (NASDAQ: SNTS), a specialty pharmaceutical company focused on therapies for gastrointestinal diseases and disorders, today reported financial results for the quarter ended March 31, 2004. In April 2004, Santarus completed an initial public offering (IPO) of common stock, which generated gross proceeds of $62.1 million, including the exercise of the underwriters' over-allotment option. "With the capital we raised through our IPO, we look forward to advancing our strategy to address therapeutic gaps in the $20 billion global gastrointestinal (GI) prescription drug market with our immediate-release proton pump inhibitor (PPI) product candidates," said Gerald T. Proehl, president and chief executive officer of Santarus. "We are working toward the achievement of several significant milestones as we transition from a company focused on R&D to one focused on the commercialization of our product candidates. Our goals for the balance of 2004 include obtaining U.S. Food and Drug Administration (FDA) approval for Rapinex(R) powder for oral suspension 20mg, and launching this product. We also plan to initiate pivotal pharmacokinetic/pharmacodynamic clinical studies with Rapinex capsules 20mg and 40mg and Rapinex chewable tablets 20mg and 40mg." FIRST QUARTER FINANCIAL RESULTS Research and development expense for the three months ended March 31, 2004 were $5.0 million, compared with $3.1 million for the comparable period last year. This increase reflects the hiring of additional personnel, higher manufacturing costs associated with formulation development and production of clinical trial materials for the Rapinex product candidates, Prescription Drug User Fee Act (PDUFA) costs associated with the submission of a New Drug Application (NDA) for Rapinex powder for oral suspension 40mg in February 2004, and expense associated with Santarus' clinical trial to evaluate the safety of Rapinex powder for oral suspension 40mg, which was initiated in October 2003 and completed in February 2004. Selling, general and administrative expense totaled $3.4 million for the first quarter of 2004, compared with $1.3 million for the first quarter of 2003. Higher SG&A expenses are attributable, in part, to the hiring of additional sales and marketing personnel and professional fees associated with preparing for commercial launch of the company's Rapinex powder for oral suspension 20mg product candidate. For the first quarter of 2004, the company reported a net loss of $10.2 million, compared with a net loss of $4.4 million for the first quarter of 2003. As of March 31, 2004, Santarus had cash, cash equivalents and short-term investments of $37.7 million and working capital of $33.2 million. These amounts do not include the proceeds of Santarus' recent IPO completed in April 2004. In its IPO, Santarus sold 6,900,000 shares of common stock (including the exercise of the underwriters' over-allotment option) at a price to the public of $9.00 per share. Net proceeds from the offering of approximately $55.9 million, as well as the number of shares issued, will be reflected in Santarus' second quarter 2004 financial results.

ABOUT PPIS PPIs are the most common prescription treatment option for upper GI diseases and disorders, including gastroesophageal reflux disease (GERD), due to their potent acid suppression, demonstrated safety and once-daily dosing. However, all currently marketed PPIs are available for oral use only in delayed-release formulations. According to IMS Health total U.S. market sales of PPI products were $12.9 billion in 2003, and prescriptions written in the U.S. for PPI products totaled 95.2 million in 2003, up 10% from 2002.
