Formulation of minitablets with personalised dissolution profile by fluid-bed granulation ofdrug nanosuspensions.

Transforming poorly soluble active pharmaceutical ingredients (APIs) into a nanoparticulate form is a proven way of improving their dissolution characteristics. The preparation of API nanosuspensions is commonly achieved by wet-stirred media milling. The challenge lies in converting the nanosuspension into a solid dosage form without compromising its re-dispersibility.
