WebJun 7, 2024 · Thiazides cause vasodilation by activating calcium-activated potassium channels (large conductance) in vascular smooth muscles and inhibiting various carbonic anhydrases in vascular tissue. Thiazide prevents the reabsorption of sodium and water from the distal convoluted tubule, allowing for the increased elimination of water in the urine. WebThiazide (/ ˈ θ aɪ ə z aɪ d /) refers to both a class of sulfur-containing organic molecules and a class of diuretics based on the chemical structure of benzothiadiazine. The thiazide drug class was discovered and developed at Merck and Co. in the 1950s. The first approved drug of this class, chlorothiazide, was marketed under the trade name Diuril beginning in 1958.

WebDec 1, 1998 · The vasodilator effect of hydrochlorothiazide in the human forearm is small and only occurs at high concentrations. The mechanism of action is not mediated by inhibition of vascular Na-Cl cotransport but involves vascular potassium channel activation. In contrast, indapamide does not exert any direct vasoactivity in the forearm vascular bed. WebThiazides and related diuretics may also cause hypokalaemia and metabolic alkalosis via a similar mechanism to loop diuretics. Thiazides and related diuretics are commonly used for the treatment of hypertension. This is not due to their direct diuretic effect, but because they cause vasodilation (the mechanism for this is poorly understood).
WebLoop diuretics cause an increase in the renal blood flow by this mechanism. This diuresis leaves less water to be reabsorbed into the blood, resulting in a decrease in blood volume. The collective effects of decreased blood volume and vasodilation decrease blood pressure and ameliorate edema. Read more about this topic: Loop Diuretic.
