Dong-A Pharmaceutical announced on Oct. 11th that it will launch Zydena 50mg, a low 
dosage pill 
(vs. existing 
100mg, 200mg) for daily treatment. This new Zydena 50mg is the world’s second erectile dysfunction daily 
treatment and is intended to boost up confidence whenever patients want without being conscious of being 
impotence.
The new Zydena 50mg is different from other existing oral erectile dysfunction pills which are needed to be 
taken before the event. If patients take this regularly (once in a day at certain time), it will help patients to 
engage in sexual activity without planning it ahead, boosting up the psychological comfort while regaining 
confidence.
Daily Zydena 50mg pill showed the meaningful clinical results as studies done by 10 domestic hospitals 
including Seoul National University Hospital since June 2008 on 237 patients showed 6.59 point improvement in 
erectile dysfunction domain (vs. placebo 3.14 point) while showing significant improvement in satisfaction and 
efficacy, scoring 75% within the treated group. Daily intake of Zydena 50mg is expected to enhance quality of 
life as one will experience improvement in sexual desire as well as sexual satisfaction.
There will be minimal side effects with insignificant occurrence of facial redness while experiencing virtually no 
interference on sexual activities. Professor Je-Jong Kim at Korea University Hospital, one of researchers who 
conducted the clinical studies, said “sales of ‘daily intake Zydena 50mg’ will give patients who did not have 
satisfying results from existing erectile dysfunction drugs another option by adding different way of intake and 
dosage.
The drug is expected to be available during the mid October at the drug stores and doctor prescription will be 
necessary
