Thalidon 25mg 10pcs

Chlorthalidone is indicated in the management of hypertension. Chlorthalidone is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis and corticosteroid and estrogen therapy.

Thiazide diuretics & related drugs

Chlortalidone prevents reabsorption of sodium and chloride by inhibiting the Na⁺/Cl⁻ symporter in the distal convoluted tubule. Thiazides and related compounds also decrease the glomerular filtration rate, which further reduces the drug’s efficacy in patients with kidney impairment (e.g. kidney insufficiency). By increasing the delivery of sodium to the distal renal tubule, chlortalidone indirectly increases potassium excretion via the sodium-potassium exchange mechanism (i.e. apical ROMK/Na channels coupled with basolateral NKATPases). This can result in hypokalemia and hypochloremia as well as a mild metabolic alkalosis; however, the diuretic efficacy of chlortalidone is not affected by the acid-base balance of the patient being treated.

Dosage & Administration

Therapy should be initiated with the lowest possible dose and then titrated according to individual patient response. A single dose given in the morning with food is recommended; divided doses are unnecessary.

Edema: Up to 50 mg daily.

Hypertension: 25 mg daily in the morning, increased to 50 mg daily if necessary.

Heart failure: 25-50 mg daily in the morning, increased if necessary to 100-200 mg daily (reduce to lowest effective dose for maintenance).

Maintenance doses may often be lower than initial doses and should be adjusted according to the individual patient.
