Case report: atenolol overdose successfully treated with hemodialysis.

Owing to the drug's favorable hydrophilic and pharmacokinetic characteristics, a number of case reports have demonstrated effective treatment of atenolol overdose with hemodialysis. However, the efficiency of atenolol clearance throughout hemodialysis treatments has not previously been examined. In this report, a patient with impaired renal function was successfully treated with two 5-hour intermittent high-flux high-efficiency hemodialysis therapies after atenolol overdose. Serial atenolol levels were measured during his hemodialysis treatments. We observed an over 50% plasma atenolol concentration reduction after each 5-hour hemodialysis therapy. Hemodialysis therapy is an effective treatment for atenolol overdose, especially in patients with impaired renal function.
