Nov 7 (Reuters) - Salix Pharmaceuticals Ltd said it has agreed to buy Santarus Inc for about $2.6 billion to acquire the specialty biopharmaceutical company's portfolio of gastrointestinal drugs.
The $32 per share offer price is a 37 percent premium to Santarus' Thursday close of $23.22 on the Nasdaq.
Santarus said it expects the deal - approved by both companies' boards - to close in the first quarter of 2014.
Santarus also said it expects the acquisition to provide "significant accretion" in 2014.
