Anti-impotence drug by South Korea's Dong-A aims for US
SEOUL: A South Korean drug maker is aiming to market a new anti-impotence drug in the United States, officials said today, adding they hope it will be the first approved South Korean product of its kind for the US market.
Dong-A Pharmaceutical Co. began South Korean sales this month of Zydena, the first South Korean-made anti-impotence drug to be approved by regulators in its home country.
The US Food and Drug Administration is conducting clinical tests of Zydena and Dong-A is looking at a 2008 target for launching the product in the United States, an official said.
The drug is effective for about a 12-hour period, the official said, adding that this compares well with major competitors.
''With Viagra's four hours, you might feel a little rushed, and with Cialis' 36 hours, the effect goes on a bit too long,'' she said.
South Korea bans prescription drug advertisements so Dong-A is hoping that offering the product at a cost lower than Pfizer's Viagra in South Korea will help it gain market share, another Dong-A official said.
The other notable erectile dysfunction drugs are Levitra sold by Bayer AG, GlaxoSmithKline Plc and Schering-Plough Corp. Cialis is sold by Icos Corp. and Eli Lilly and Co.
