Hi All, When I was searching for "transdermal" for Nancy's Sinemet Patch, I chanced on this....... MACROCHEM has developed a topically applied gel product for treating erectile dysfunction, Topiglan. It is a formulation of alprostadil with SEPA®, MacroChem’s patented transdermal drug delivery technology. Alprostadil has been approved in the US for the treatment of erectile dysfunction. A Phase IIA clinical study of Topiglan’s efficacy demonstrated a 67 - 75 percent response compared with a 17 percent response in patients treated with a placebo. Phase IIB is ongoing and confirming the positive response demonstrated from the earlier study. MACROCHEM believes that when Topiglan is approved for marketing, this non-invasive product will become one of the preferred methods of treating erectile dysfunction. The finger on this page holds 1/4 ml. of TopiglanTM, a representation of the volume of gel applied for a single application. MacroChem has filed a federal trademark application with the U.S. Patent and Trademark Office for the mark Topiglan, its SEPA/alprostadil gel for treating male erectile dysfunction. http://www.mchm.com/topiglan.htm and then there was this mind boggling press release...... 4/03/00 MacroChem Will Exhibit Innovative Investigational Drug For Erectile Dysfunction at World's Largest Meeting of Urologists cheerz ......... murray [log in to unmask]
