Headline: Asensio & Company: Zonagen's Vasomax Patent Application Exposed ====================================================================== NEW YORK, Jan. 14 /PRNewswire/ -- Asensio & Company issued the following statement today: Zonagen, Inc. (BB: ZONA) has not disclosed the contents of its U.S. Vasomax patent application. However, Zonagen also filed an International Application under the Patent Cooperation Treaty that includes the Vasomax formulation. This application is publicly available and contradicts Zonagen's Vasomax discovery claims. The application confirms that Vasomax's only active ingredient is unaltered generic phentolamine. It also reveals that Vasomax contains no ingredient that can alter phentolamine's chemistry or its effects on the circulatory system. In fact, 212 mg of Vasomax's total 400 mg tablet is lactose, commonly known as milk sugar. Last Friday, Asensio & Company released a report on charges that Zonagen had filed a fraudulent ImmuMAX patent application and had failed to disclose it had been rejected. Despite this, Zonagen continued to promote ImmuMAX to investors and attempted to sell ImmuMAX rights to several companies including Schering-Plough. Likewise, Zonagen filed a Vasomax patent application despite having made no discovery and the prior existence of extensive phentolamine MED studies and products. A complete report on Zonagen's Vasomax patent application, including a description of Vasomax's ingredients and formulation, is available on Asensio & Company, Inc.'s home page located on the Internet atasensio.com . The report on Zonagen's ImmuMAX patent and discovery fraud charges and a complete Zonagen research report are also available at Asensio's Internet site in its Current Reports section under Zonagen. Asensio & Company maintains a Strong Sell recommendation on Zonagen shares. SOURCE Asensio & Company, Inc. -0- 01/14/98 /CONTACT: Manuel P. Asensio of Asensio & Company, 212-702-8800/
