High-Tensile-Strength Paracetamol Tablets

June 15, 2015


Fast-dissolving products are of high interest in the pharmaceutical industry due to drug delivery issues as well as in the food industry. The freeze-casting process can be applied not only to produce dense materials, but also to create materials with adjustable porous microstructures. The low-temperature process facilitates the formulation of drug carrier systems, and the designable microstructure can promote matrix-solvent interaction, therefore, it improves the drug dissolution, bioavailability, the therapeutic effect of the active ingredients as well as the capability to prolong the life time of a bioproduct. P. T. N. Nguyen and J. Ulrich successfully produced fast dissolving porous dosage forms (tablets), containing paracetamol as the active pharmaceutical ingredient and modified starch as an additive, by the freeze-casting technique. The freeze-casted tablets own equal tensile strength and a threefold faster disintegration time compared to commercial compressed tablets, i.e., < 3 min in comparison to 10 min of commercial tablets.
