Zusammenfassung:We report a 53-year-old woman with hyperkaliemia secondary to treatment with atenolol. The diagnosis of atenolol induced hyperkaliemia was obtained after excluding other causes of hyperkaliemia and normalization of potassium serum level following the discontinuation of this medication without any other modification (treatment or diet). Furthermore, when atenolol was again introduced, serum potassium level increased and normalized when atenol was definitively discontinued. The mechanism of hyperkaliemia we suspected is probably a reduction of potassium intracellular transfer.
