Abstract: The present invention relates to crystalline polymorphic forms of the di-sodium salt of N-(5-chlorosalicyloyl)-8-aminocaprylic acid, pharmaceutical compositions containing the same, methods of preparing the same, and methods for facilitating the delivery of active agents with the same.

Abstract: Oral insulin formulations and processes for preparing oral insulin formulations are provided.

Abstract: The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. 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 of preparing the disodium salt, ethanol solvate, and hydrate and compositions containing the disodium salt, ethanol solvate, and/or hydrate.

Abstract: The inventors have discovered that the disodium salt of certain delivery agents has surprisingly greater efficacy for delivering active agents than the corresponding monosodium salt. Furthermore, the inventors have discovered that the disodium salts of these delivery agents form solvates with ethanol and hydrates with water. The delivery agents have the formula wherein R1, R2, R3, and R4 are independently 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 the formula above.

Abstract: Disclosed are improved methods for the synthesis of N-(8-[2-hydroxybenzoyl]-amino)caprylic acid. Certain compounds have been found useful for preventing the formation of a colored impurity when included in an ester hydrolysis reaction. Conducting ester hydrolysis in anaerobic conditions has also been found to minimize the formation of the color impurity. Also disclosed are improved methods for synthesizing the sodium salt of N-(8-[2-hydroxybenzoyl]-amino)caprylic acid.
