Metolazone tablets are indicated for the treatment of salt and water retention including: - edema accompanying congestive heart failure; - edema accompanying renal diseases, including the nephrotic syndrome and states of diminished renal function. Metolazone tablets are also indicated for the treatment of hypertension, alone or in combination with other antihypertensive drugs of a different class. Mykrox® tablets, a more rapidly available form of metolazone, are intended for the treatment of new patients with mild to moderate hypertension. A dose titration is necessary if Mykrox® tablets are to be substituted for Zaroxolyn® tablets and other formulations of metolazone that share its slow and incomplete bioavailability, in the treatment of hypertension. The routine use of diuretics in an otherwise healthy woman is inappropriate and exposes mother and fetus to unnecessary hazard.

CLINICAL PHARMACOLOGY
Metolazone is a quinazoline diuretic, with properties generally
similar to the thiazide diuretics. The
actions of metolazone result from interference with the renal tubular
mechanism of electrolyte
reabsorption. Metolazone acts primarily to inhibit sodium reabsorption
at the cortical diluting site and to
a lesser extent in the proximal convoluted tubule. Sodium and chloride
ions are excreted in
approximately equivalent amounts. The increased delivery of sodium to
the distal tubular exchange site
