Abstract

The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than t he corresponding monosodium salt. Furthermore, the inventors have discovered th at the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. The delivery agents have formula (I) wherein R1, R2, R3 , and R4 are indepedently hydrogen, halogen, C1-C4 alkyl, or C1-C4 alkoxy; and R5 is a substituted or unsubstituted C2-C16 alkylene, substituted or unsubstituted C2-C16 alkenylene, substituted or unsubstituted C1-C12 alkyl(arylene), or substituted or unsubstituted aryl(C1-C12 alkylene). The hydrates and solvates of present invention also have surprisingly greater efficacy for delivering active agents, such as heparin and calcitonin, than their corresponding monosodium salts and free acids. The present invention provides an alcohol solvate, such as ethanol solvate, of a disodium salt of a delivery agent of formula (I) above. Preferred delivery agents include, but are not limited to, N-(5-chlorosalicyloyl)-8-aminocaprylic acid (5-CNAC),N-( 10- [2-hydroxybenzoyl]amino)decanoic acid (SNAD), and sodium N-(8-[2- hydroxybenzoyl]amino)caprylate (SNAC). The invention also provides methods o f preparing the disodium salt, ethanol solvate, and hydrate and compositions containing the disodium salt, ethanol solvate, and/or hydrate.
