The preparation of tablet using drug layered controlled release beads is an important goal to the pharmaceutical industry.   However, this effort is challenged by poor compressibility of functionally coated beads.  It is usually difficult to make sufficient strong tablets from such beads without compromising the integrity of the functional coating layer.  In this talk, we will discuss how a top coating strategy (using highly bonding polymers) can be used to overcome this problem.
