Recent advertisements for indapamide (Lozol - Rorer), an oral antihypertensive/diuretic (Medical Letter, 26:17, 1984), claim that the drug, unlike thiazide diuretics, does not significantly increase serum cholesterol and has a minimal impact on potassium. Indapamide has no thiazide ring but, like chlorthalidone (Hygroton; and others) and hydrochlorothiazide (HydroDiuril; and others), it does have a sulfamoyl benzamide moiety, which is probably responsible for its natriuretic and diuretic effects. Unlike the thiazides, it also has a methylindoline moiety, which apparently decreases peripheral resistance.

Microx (Pennwalt), a new low-dosage formulation of the thiazide-type diuretic metolazone (Zaroxolyn; Diulo), was recently marketed in the USA. The manufacturer claims that the low dose of controls hypertension with less potassium loss, making it safer than other diuretics and as effective as combination drugs, such as Dyazide, that include both a thiazide and a potassium-sparing diuretic. Medical Letter consultants generally do not recommend Dyazide or other fixed-dose combinations for treatment of hypertension.
