Metxone Tablets SpecificationRequires Prescription (YES/NO)YesGenericsMetolazoneUsed ForHypertensionHow it worksIt is a quinazoline diuretic, with properties generally similar to the thiazide diuretics. The actions of Metolazone result from interference with the renal tubular mechanism of electrolyte reabsorption. Metolazone acts primarily to inhibit sodium reabsorption at the cortical diluting site and to a lesser extent in the proximal convoluted tubule. Sodium and chloride ions are excreted in approximately equivalent amounts. The increased delivery of sodium to the distal-tubular exchange site results in increased potassium excretion.Metxone Tablets Usage And SafetyDosageMetolazoneSide EffectsCardiovascular: Chest pain/discomfort, orthostatic hypotension, excessive volume depletion, hemoconcentration, venous thrombosis, palpitations.

Metolazone has also been used in the management of mild to moderate essential hypertension alone or in combination with other antihypertensive drugs of a different class.When not to UseIt is contraindicated in anuria, in hepatic coma or pre-coma, and in cases of known allergy and hypersensitivity to metolazone.Metxone Tablets PrecautionsPrecautionAll patients receiving metolazone should have serum electrolytes measured at appropriate intervals and be observed for clinical signs of fluid and/or electrolyte imbalance; namely, hyponatremia, hypochloremic alkalosis, and hypokalemia. Serum and urine electrolyte determinations are particularly important when the patient is vomiting excessively, has severe diarrhea, or is receiving parenteral fluids.Metxone Tablets WarningsWarning 1The rapid onset of severe hyponatremia and/or hypokalemia has been reported following initial doses of thiazide and non-thiazide diuretics. When symptoms consistent with severe electrolyte imbalance appear rapidly, the drug should be discontinued and supportive measures should be initiated immediately. The appropriateness of therapy with this class of drug should be carefully re-evaluated.Warning 2Hypokalemia may occur, with consequent weakness, cramps, and cardiac arrhythmias. Hypokalemia is a particular hazard in digitalized patients or those who have had or have a ventricular arrhythmia; dangerous or fatal arrhythmias may be precipitated. Serum potassium should be determined at regular intervals, and dose reduction, potassium supplementation or addition of a potassium sparing diuretic instituted if indicated. Hypokalemia is dose related.Warning 3Azotemia and hyperuricemia may be noted or precipitated during the administration of metolazone. Infrequently, gouty attacks have been reported in persons with a history of gout. If azotemia and oliguria worsen during treatment of patients with severe renal disease, metolazone should be discontinued.Metxone Tablets Additional InformationPregnancy categoryAlways consult your physician before using any medicine.Storage (YES/NO)Store this medicine at room temperature, away from direct light and heat.
