Web25 jun. 2024 · The molecular mechanism of the lithium reabsorption has not been fully elucidated, and only epithelial sodium channel ENaC located in the brush-border membrane of collecting duct was shown to mediate lithium uptake into principal cells by in vitro experiment ( Kortenoeven et al. 2009 ). Webcan be used. Amiloride decreases the lithium entry into prin- cipal cells by inhibiting ENaC. iazides induce hypovolemia and increase the proximal tubular water reabsorption and thus reduce polyuria.
