4.4 Drug Indication

Polythiazide is a thiazide diuretic used to decrease edema and decrease blood pressure.


5 Pharmacology and Biochemistry
5.1 Pharmacology

As a thiazide diuretic, Polythiazide inhibits the sodium-chloride symporter which decreases solute reabsorption leading to a retention of water in the urine, as water normally follows solutes. More frequent urination is due to the increased loss of water that has not been retained from the body as a result of a concomitant relationship with sodium loss from the convoluted tubule. The short-term anti-hypertensive action is based on the fact that thiazides decrease preload, decreasing blood pressure


5.2 MeSH Pharmacological Classification

Diuretics

Agents that promote the excretion of urine through their effects on kidney function. (See all compounds classified as Diuretics.)


Sodium Chloride Symporter Inhibitors

Agents that inhibit SODIUM CHLORIDE SYMPORTERS. They act as DIURETICS. Excess use is associated with HYPOKALEMIA. (See all compounds classified as Sodium Chloride Symporter Inhibitors.)


Antihypertensive Agents

Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. (See all compounds classified as Antihypertensive Agents.)

5.8 Mechanism of Action

As a diuretic, polythiazide inhibits active chloride reabsorption at the early distal tubule via the thiazide-sensitive Na-Cl cotransporter (TSC), resulting in an increase in the excretion of sodium, chloride, and water. Thiazides like polythiazide also inhibit sodium ion transport across the renal tubular epithelium through binding to the thiazide sensitive sodium-chloride transporter. This results in an increase in potassium excretion via the sodium-potassium exchange mechanism. The antihypertensive mechanism of polythiazide may be mediated through its action on carbonic anhydrases in the smooth muscle or through its action on the large-conductance calcium-activated potassium (KCa) channel, also found in the smooth muscle.


DOMINANT ACTION OF THIAZIDES IS TO INCR RENAL EXCRETION OF SODIUM & CHLORIDE & ACCOMPANYING VOL OF WATER. THIS EFFECT IS VIRTUALLY INDEPENDENT OF ACID-BASE BALANCE. /BENZOTHIADIAZIDE DIURETICS/

Gilman, A. G., L. S. Goodman, and A. Gilman. (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 6th ed. New York: Macmillan Publishing Co., Inc. 1980., p. 899


RENAL ACTIONS OF THIAZIDE DIURETICS DECR EXTRACELLULAR FLUIDS & PLASMA VOL, CARDIAC OUTPUT, & TOTAL EXCHANGEABLE SODIUM IN INDIVIDUALS WITHOUT ANY EVIDENCE OF CARDIAC FAILURE. AT THIS STAGE, SODIUM & WATER DEPLETION APPEARS TO PROVIDE ADEQUATE BASIS FOR ANTIHYPERTENSIVE EFFECT... /BENZOTHIADIAZIDE DIURETICS/

Gilman, A. G., L. S. Goodman, and A. Gilman. (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 6th ed. New York: Macmillan Publishing Co., Inc. 1980., p. 901


GLOMERULAR FILTRATION RATE MAY BE REDUCED BY THIAZIDES... THIS IS PRESUMABLY RESULT OF DIRECT ACTION ON RENAL VASCULATURE. ...THIAZIDES DECR RENAL EXCRETION OF CALCIUM RELATIVE TO THAT OF SODIUM, SINCE ITS REABSORPTION IS UNAFFECTED IN DISTAL NEPHRON WHEREAS THAT OF SODIUM IS BLOCKED. /BENZOTHIADIAZIDE DIURETICS/

Gilman, A. G., L. S. Goodman, and A. Gilman. (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 6th ed. New York: Macmillan Publishing Co., Inc. 1980., p. 901


BECAUSE HEMODYNAMIC MEASUREMENTS INDICATE THAT PERIPHERAL VASCULAR RESISTANCE IS DECR BY THIAZIDES, DIRECT ACTION OF THESE DRUGS ON ARTERIOLAR SMOOTH MUSCLE HAS BEEN SUGGESTED. /BENZOTHIADIAZIDE DIURETICS/

Gilman, A. G., L. S. Goodman, and A. Gilman. (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 6th ed. New York: Macmillan Publishing Co., Inc. 1980., p. 804
