Chronic hypotension, infrequent though possible in chronic renal failure pa
tients on hemodialysis, has harmful consequences on their physical state an
d hence general well-being. These patients often experience acute intradial
ytic manifestations while non-pharmacologic interventions as pharmacologic
agents are sometimes insufficient to improve symptoms. Well tolerated, mido
drine appears to be a suitable and effective agent as it raises blood press
ure significantly via its effect on peripheral a-adrenergic receptors. The
authors describe their use of midodrine in a dialysis patient for the longe
st period of time reported up to now, documented by a pharmacokinetic study
, confirming long-term both clinical efficacy and safety of the drug.
