Solid state suspensions (soft chews), where an insoluble active ingredient is suspended in a semi-solid matrix, provide for very rapid dissolution profiles and superior taste masking. These are an ideal delivery format for children. Our OxpChew™ solid state suspensions are matrices comprised of sugar and non-sugar carbohydrates which are naturally sweet and act as an excellent taste masker. We have a granted patent in the UK for this delivery system and expect the European patent application to be granted in 2012.

We currently market a calcium supplement using this technology where calcium carbonate particles are uniformly and substantially dispersed over the matrix. The matrix primarily composed of carbohydrates dissolves quickly at stomach conditions, helps the "wetting" of each individual particle, and releases them in conditions ideal for solubilisation. Tests on dissolution have demonstrated significant improvements in the dissolution profile of this system relative to standard calcium tablets and chewable tablets.
