How do thiazide diuretics work in the treatment of hypertension?
By decreasing sodium reabsorption, thiazide use acutely results in an increase in fluid loss to urine, which leads to decreased extracellular fluid (ECF) and plasma volume. This volume loss results in diminished venous return, increased renin release, reduced cardiac output and decreased blood pressure [7].
