Abstract
Methods for preparing cocrystals wherein solutions of active agents in suitable liquids are combined with solutions of guests, both with and without suitable liquids, in an interface region are described herein. Methods for analyzing the cocrystals are also described.
Claims10
A method for screening a cocrystal of an active agent and a guest comprising the steps of:
- a. Contacting the active agent with a suitable liquid to form an active-agent solution;
- b. Contacting the active-agent solution with a guest solution to form a mixture of solutions in an interface region;
- c. Solidifying the solution mixture in the interface region to form a solid;
- d. Analyzing the solid for the presence of a cocrystal.
