疗效迹象:

Metolazone tablets are indicated for the treatment of salt and water retention including: 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. Diuretics do not prevent development of toxemia of pregnancy, and there is no evidence that they are useful in the treatment of developed toxemia. Edema during pregnancy may arise from pathologic causes or from the physiologic and mechanical consequences of pregnancy. Metolazone tablets

DESCRIPTION
Metolazone Tablets, USP for oral administration contain 2.5 mg, 5 mg
or 10 mg of metolazone, USP, a
diuretic/saluretic/antihypertensive drug of the quinazoline class.
Metolazone has the molecular formula C
H ClN O S, the chemical name 7-chloro-1, 2, 3, 4-
tetrahydro-2-methyl-3-(2-methylphenyl)-4-oxo-6-quinazolinesulfonamide,
and a molecular weight of
365.83. The structural formula is:
Metolazone is only sparingly soluble in water, but more soluble in
plasma, blood, alkali, and organic
solvents. Inactive Ingredients: colloidal silicon dioxide, FD&C Yellow
#6 Lake HT, magnesium
stearate and microcrystalline cellulose. In addition, the 10 mg
strength contains D&C Yellow #10 Lake
HT and FD&C Blue #2 Lake HT.
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 severely compromise
