Chlorthalidone acts as a diuretic, aiding in blood pressure management. Promotion of water and electrolyte excretion through the distal convoluted tubule reduces peripheral vessel resistance over time.
What is Chlorthalidone? It belongs to the thiazide-like diuretic class and is the active compound that helps the kidneys remove excess fluid. In Singapore, this substance is listed on the label of several Chlorthalidone medications and is regulated by the Health Sciences Authority. Its main therapeutic purpose is to aid in controlling fluid balance, which can affect blood pressure and swelling.
Chlorthalidone is offered in tablet form, typically ranging from 12.5 mg to 25 mg strengths. Both generic versions and branded products carry the same active ingredient, though the packaging and brand name may differ. Patients in Singapore will find the tablets available at pharmacies and hospitals, labelled clearly as containing the Chlorthalidone active ingredient.
