• Reproducible granulation process with a power value based endpoint.
• Fast dissolving minitablets were produced using hard fat as sole excipient.
• Taste improvement of all formulations was confirmed by e-tongue measurements.
• Precise and accurate dosing is feasible using a special dosing spoon.
Sodium benzoate is a highly soluble orphan drug with unpleasant taste and high daily dose. The aim of this study was to develop a child appropriate, individually dosable, and taste masked dosage form utilizing lipids in melt granulation process and tableting. A saliva resistant coated lipid granule produced by extrusion served as reference product. Low melting hard fat was found to be appropriate as lipid binder in high-shear granulation. The resulting granules were compressed to minitablets without addition of other excipients. Compression to 2 mm minitablets decreased the dissolved API amount within the first 2 min of dissolution from 33% to 23%. The Euclidean distances, calculated from electronic tongue measurements, were reduced, indicating an improved taste. The reference product showed a lag time in dissolution, which is desirable for taste masking. Although a lag time was not achieved for the lipidic minitablets, drug release in various food materials was reduced to 2%, assuming a suitable taste masking for oral sodium benzoate administration.
