This is a 12 week study in which different doses and formulations of UK-369,003 will be
administered to patients with a diagnosis of enlarged prostate. Patients will complete a
series of questionnaires before, during and after treatment to assess if UK-369,003 has
improved their urinary symptoms and erectile function . There will be several blood samples
taken during the study to asses the level of drug in the blood and correlate it with the
responses to the questionnaires.
