Abstract
Most drugs are delivered as crystalline solids, but some widely used pharmaceutical ingredients cannot be crystallized at ambient conditions: propofol, one of the most widely used anesthetic agents in the world is a liquid. Here we stabilize propofol in a crystalline phase by cocrystallization, and we thoroughly characterize the structural and thermodynamic properties of the new materials. Ternary solubility diagrams of a liquid pharmaceutical ingredient cocrystallized with a solid coformer are presented and analyzed for the first time. It is shown that, when equilibrated with the solid cocrsytal, the concentration of propofol in water is kept constant in a wide range of starting compositions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
