Oral medications that are approved for the treatment of painful diabetic neuropathy include anticonvulsants such as Lyrica (pregabalin), the antidepressant Cymbalta (duloxetine) and the opioid Nucynta (tapentadol), with sales for the treatment of neuropathic pain totaling over $3 billion in the U.S. according to Datamonitor. These treatments are modestly effective in relieving symptoms and their use can be limited by adverse effects and drug interactions. BDSI believes that a topical clonidine gel offers a novel mechanism of action to the available therapies with an improved safety and tolerability profile. BDSI estimates annual peak sales potential for this product in excess of $300 million.About BioDelivery Sciences International BioDelivery Sciences International (NASDAQ: BDSI) is a specialty pharmaceutical company that is leveraging its novel and proprietary patented drug delivery technologies to develop and commercialize, either on its own or in partnerships with third parties, new applications of proven therapeutics.
