Abstract
X-ray powder diffraction was used to determine the percent crystallinity in blends of crystalline and X-ray amorphous MK-0591, a potent indirect leukotriene biosynthesis inhibitor. A linear calibration curve was obtained. Preliminary studies using powder blends of MK-0591 with pregelatinized starch, microcrystalline cellulose, and magnesium stearate demonstrated the feasibility of using this method to determine (or quantify) the percent crystallinity of MK-0591 in tablet formulations.
