SNAC, is a pyrophosphate absorption enhancer used in the treatment of gastrointestinal diseases, particularly suitable for gastrointestinal disorders caused by poor absorption of pyrophosphate compounds.

Salcaprozate sodium (SNAC) is an oral absorption enhancer with the potential to act as a delivery agent for oral forms of heparin and insulin. Salcaprozate sodium can increase the lipophilicity induced by non-covalent large molecule complexes, thereby enhancing the passive transcellular permeation through the small intestinal epithelial cells.
