Web22 jun. 2015 · Most of the filtered lithium is reabsorbed in the proximal tubule, about 20% between the loop of Henle and the collecting duct. The underlying mechanisms involve mainly two transmembrane proteins, the sodium (Na + )–hydrogen (H +) exchanger (NHE) and the ENaC, both of which are amiloride sensitive ( Fig. 1 a). WebLithium seems to be reabsorbed mainly or exclusively in the proximal tubules. Determination of the fractional lithium reabsorption is simple; it may be a useful tool for …

Web1 nov. 2003 · Lithium is excreted almost entirely by the kidney. However, anywhere from 60-75% of the filtered load is reabsorbed in the proximal tubule. Since lithium is handled by the kidney in a manner very similar to sodium, any underlying condition with volume or sodium depletion will result in increased lithium reabsorption. WebLithium is excreted primarily in urine with less than 1% being eliminated with the feces. Lithium is filtered by the glomeruli and 80% of the filtered lithium is reabsorbed in the tubules, probably by the same mechanism responsible for sodium reabsorption. The renal clearance of lithium is proportional to its plasma concentration.
