  • Title: An unusual cause of hypokalemic muscle weakness.
    Author: Valeriano J, Tucker P, Kattah J.
    Journal: Neurology; 1983 Sep; 33(9):1242-3. PubMed ID: 6684266.
    Abstract:
    A 36-year-old woman presented with proximal muscle weakness, cramps, and a serum potassium level of 2.7 mEq/l. During her hospitalization she was noted to use excessive quantities of a snuff preparation containing glycyrrhizinic acid, a potent mineralocorticoid analogue. With discontinuation of this substance, her potassium returned to normal values and her strength improved. This case is submitted as a hypokalemia myopathy induced by snuff dipping.
