Abstract

Salicylsalicylic acid (“Salsalate”) is a non-steroidal anti-inflammatory drug with anti-rheumatic properties, whose amorphous form offers the potential for enhanced dissolution rates and improved bioavailability compared with its crystalline counterpart. It has been reported to form a stable glassy phase on heating and rapid quenching. A number of the existing studies of the solid-state structure of salsalate and of its thermal decomposition contain information that is difficult to reconcile. In this article, we review much of the existing literature in light of our own recent studies using solution-state nuclear magnetic resonance, mass spectrometry, and solid-state infrared spectroscopy, and conclude that much of the literature data relating to melting and the glassy state is questionable due to failure to take into account the effects of thermal decomposition. © 2016 American Pharmacists Association®
