Answer

Hypokalemia may be precipitated by a diet that is rich in sodium or the concomitant administration of drugs that produce kaliuresis (including diuretics and carbenoxolone). Taking carbenoxolone or eating large quantities of licorice may result in hypokalemia because of blockade of the target tissue enzyme that protects the aldosterone receptor from the relatively higher levels of circulating cortisol (apparent mineralocorticoid excess).
