WebLithium is capable to activate GPCRs, and to induce phosphorylation of protein kinase C (16), a key factor in the intracellular reactions usually induced by the activation of the CASR; as a monovalent cation, lithium might be thought to be a weak activator of the CASR. Web1 mrt. 2016 · Hypercalcemia was identified a mean 5.2 years (median, 3.9 years) after thiazide initiation (range, 4 days to 33 years). The average highest serum calcium was 10.72 mg/dL [2.67 mmol/L] (range, 10.2 to 12.5 mg/dL [2.5–3.1 mmol/L]). Most subjects were treated with thiazides for hypertension (94%).
