Apricus Biosciences (formerly NexMed) wants you to rub it in. The drug development company uses its NexACT technology to deliver drugs through the skin; it is developing topical formulations with improved absorption rates, using already-proven drug ingredients. One of the company's products is a treatment for erectile dysfunction, Vitaros, that is sold in select international markets. Another offering, Totect, works to detoxify tissue that has been accidentially exposed to chemotherapy agents. Apricus Biosciences is also working on a topical product called Femprox that treats female sexual arousal disorder, as well as a topical nail fungus treatment called MycoVa.
