The present invention features a tablet containing at least one first material, at least one second material, and at least one pharmaceutically active agent, wherein:(a) the first material is a dielectric water-containing material (i) containing from about 1 to about 5 percent, by weight, of bound water and (ii) having a dielectric loss, when measured at a density of between 0.15 and 0.5 g/cc, of from about 0.05 to about 0.7 and(b) the second material (i) having a water solubility from about 20 to about 400 g per 100 g of water at 25° C., (ii) having a dielectric loss, when measured at a density between 0.5 and 1 g/cc, of less than about 0.05.
