6. Presence of severe renal disease (BUN 50% greater than normal). Patients must have evidence from their PCP or Urologists of normal PSA and urodynamic tests within the last 12 months; patients with BUN 50% greater than normal (5 to 20 mg/ d L) or creatinine 50% greater than normal (0 .7 and 1.4 mg/ d L) will be excluded. Labs will be requested from PCP.

Concomitant or prior therapy with the following treatments: neuroleptics, metoclopramide, domperidone (in doses >60mg/day), azole antifungals (e.g. ketoonazole), etomidate, ciprofloxacin, fluvoxamine, cimetidine, fludrocortizone, encainide, flecainide, mexiletine, propafenone, guanoxane, maprotiline, antidepressants on doses higher than the maximum approved daily dose for outpatients, intermittent therapy with oral corticoids.
