More specifically, it is found that when DMSO and urea are both administered to epithelial regions of a human or other animal subject, expected adverse skin reactions, malodorous breath and foul taste are substantially reduced. In most cases they are entirely eliminated.
Furthermore, urea is discovered to potentiate DMSO in certain instances. It appears that a DMSO composition containing urea and/or ethanol is more rapidly absorbed into tissue than are similar compositions containing no urea or ethanol. If the DMSO composition includes another pharmaceutical substance, such other substance is also absorbed more rapidly when urea and/or ethanol are present. The presence of NaCl, KCl and/or acetamide reduces discomfort resulting from topical application of DMSO compositions and appears to further enhance penetration.
It has also been discovered that certain DMSO formulations, which contain urea, are effective in treating diseased finger and toe nails, for softening cuticle to be removed from finger and toe nails, and for softening epidermal thickenings to ease removal.
