Reaction Steps

Hydromorphone beads were prepared by dissolving hydromorphone HCl in water, adding Opadry®, and mixing for about 1 hour, and then spraying onto nu pariel 18/20 beads using a Wurster insert. The resultant coated beads were then overcoated with Opadry® Y-5-1442 light pink (15% w/w). The beads were then overcoated with an aqueous dispersion of Aquacoat® to a 15% weight gain according to Table 15 below:
