Webthis route of excretion for lithium is primary, accumulation to potentially toxic levels may occur. Inhibition of renal prostaglandins may also increase proximal sodium reab sorption with attendant enhanced lithium reabsorption.8 Sulindac is metabolized intrarenally to its inactive forms, sulindac sulfoxide and sulindac sulfone, which Webinﬂuence lithium serum concentrations by inducing sodium depletion and thereby stimulating proximal sodium and therefore lithium reabsorption. RAS inhibitors induce volume depletion and in this manner reduce glomerular ﬁltration rate, which may lead to a reduction in lithium clearance. Up to now, theophyllin has been implicated in lowering

Web19 apr. 2024 · However, the role of lithium on PT albumin reabsorption and its correlation with the development of TII have still to be determined. Albumin reabsorption in PT cells occurs by receptor-mediated endocytosis; megalin is the main receptor involved in this process [12,13,17]. WebThe kidneys are responsible for 95% of lithium excretion, and the rest is removed through sweat and feces. The kidneys treat lithium and sodium similarly which is the reason sodium depletion can significantly elevate lithium reabsorption [14].
