solid-state properties of the pro-drug were fully investigated, and extensive polymorph screening was undertaken. An unusual low-temperature endothermic event was observed in the differential scanning calorimetry thermogram. This low-temperature event was further investigated using variable-temperature X-ray powder diffraction and variable-temperature solid-state nuclearmagneticresonancespectroscopy. It
Ester derivatives of the phenolic hydroxyl group of buprenorphine can be used in the treatment of opiate dependency and/or moderate to severe pain. The esters have an enhanced bioavailability, an enhanced duration of action, and a reduced abuse potential.
