Terapeutiska indikationer:

Metolazone tablets USP 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 USP 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. Diuretics do not prevent development of toxemia of pregnancy, and there is no evidence that they are useful in the treat

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
results in increased potassium excretion. Metolazone does not inhibit
carbonic anhydrase. A proximal
action of metolazone has been shown in humans by increased excretion
of phosphate and magnesium
ions and by a markedly increased fractional excretion of sodium in
patients with seve
