The use of diuretics in modern antihypertensive therapy.

A review is made to sum up the indications when diuretics may be the drug of choice in the treatment of hypertension. Advantages from the combined treatment of thiazide diuretics and other antihypertensive agents are also emphasized. Adverse effects from diuretic treatment, i.e. hypokalemia, hyperuricemia, impaired glucose tolerance and risks associated with unfavourable serum lipoprotein patterns are discussed. It is concluded that from a hemodynamic point of view thiazide diuretics can be a good therapeutic alternative for most patients, excepting those with hyperkinetic circulation. It is recommended to use lower doses of thiazide diuretics than previously and the monitoring of S-potassium is necessary in all patients.
