Key points

  • Chlorthalidone is a diuretic that works by making the kidneys remove more salt and water into the urine.
  • The official label for Thalitone, a US chlorthalidone brand, describes it as a tablet.
  • Chlorthalidone can affect the body’s fluid and electrolyte balance, so its prescribing information calls for laboratory monitoring.

What Chlorthalidone is used for

Chlorthalidone is prescribed for Hypertension, to bring high blood pressure down over time. It is also used for Oedema, swelling caused by the body holding onto extra fluid.

Brands and forms in this catalogue

Hygroton is the single-ingredient chlorthalidone tablet in this catalogue, with Novartis as its originator. The other three brands pair chlorthalidone with a second blood pressure medicine in one tablet: Combipres adds clonidine (originator Boehringer Ingelheim), Tenoretic adds atenolol (originator AstraZeneca), and Edarbyclor adds azilsartan medoxomil (originator Takeda). All four are tablets, so what sets them apart is the combination of active ingredients rather than the form. Each falls under the Heart & Blood Pressure part of the catalogue.
