The first patent claims a layered immediate-release (IR) tablet having at least two different active ingredients segregated from each other by a drug-free layer. The innovative tablet design may be used to combine medications in a way that allows them to be administered together in a single tablet, as in traditional fixed-dose combination tablets, but also enables the two medications to be accurately separated if medically indicated simply by splitting the tablet through the drug-free layer.
The second patent also claims divisible tablets, but involves the creation of tablets that contain a half dose of the same active (or combination of the same actives) on each end of the tablet, separated by a drug-free break layer. Division of these tablets through the drug-free break layer would provide an accurate partial dose of the active, useful for titration and dose adjustment.
