Zestoretic

Derivative of benzothiadiazepine selectively blocks the transport system of sodium ions, potassium and chlorine, stopping its transport across the apical membrane into cells of the epithelium of the thick segment of ascending part of Henles loop. The suppression of the re-absorption of ions leads to their excretion from the body. Ions of calcium and magnesium are excreted simultaneously with the ions of sodium, potassium and chlorine.

Description

Pharmacodynamics of Zestoretic:

Combined antihypertensive drug.

Derivative of benzothiadiazepine selectively blocks the transport system of sodium ions, potassium and chlorine, stopping its transport across the apical membrane into cells of the epithelium of the thick segment of ascending part of Henles loop. The suppression of the re-absorption of ions leads to their excretion from the body. Ions of calcium and magnesium are excreted simultaneously with the ions of sodium, potassium and chlorine. Hypocalcemia does not develop due to active re-absorption in the distal convoluted canalize of the Henles loop.

It is effective in case of any fluctuations of acid-base balance, preserves a diuretic effect both in case of acidosis and alkalosis.

The drug blocks the conversion of angiotensin I to angiotensin II, resulting in decreased release of norepinephrine from the endings of sympathetic fibers, vasoconstrictor effect, secretion of aldosterone by the adrenal cortex and increase of the amount of bradykinin by decreasing its inactivation of angiotensin converting enzyme.

Bradykinin stimulates B2-kinin receptors in vascular endothelium, leading to rapid release of prostacyclin and other vasodilator substances that cause smooth muscle relaxation.

It reduces the total peripheral vascular resistance without affecting heart rate.

The half-life is 6.4 hours. It is eliminated by the kidneys, about 75% in an unmodified form.

The therapeutic effect develops within 1 hour after ingestion, reaches its maximum after 6 hours and lasts for 24 hours. It doesn’t cause the withdrawal syndrome. It penetrates through the blood-brain and placental barrier, and is excreted in breast milk.  It is not metabolized.

The half-life is 12 hours. Elimination occurs in the kidneys in unchanged form.

Drug interaction:

It enhances the effects of depolarizing muscle relaxants.

Patients with diabetes require the correction doses of oral hypoglycemic agents and insulin preparations in case of the reception of hydrochlorothiazide.

It increases hypoglycemic effect of corticosteroids, adrenocorticotropic hormone, carbenoxolone, amphotericin b, cardiac glycosides.

Anticholinergic drugs increase the bioavailability of hydrochlorothiazide.

The simultaneous use with the lithium drug may cause a manifestation of a paradoxical antidiuretic effect.

The simultaneous use of vitamin D and calcium may develop hypercalcemia.

The simultaneous use of cyclosporine increases the risk of development of gout and hyperuricemia.
