dailymed-instance:dosage |
Therapy should be individualized according to patient response.
Use the smallest dosage necessary to achieve the required response.<br/>Adults:<br/>For Edema: The usual adult dosage is 0.5 to 1.0g (10 to 20 mL) once or twice a day. Many patients with edema
respond to intermittent therapy, i.e., administration on alternate days or
on three to five days each week. With an intermittent schedule, excessive
response and the resulting undesirable electrolyte imbalance are less likely
to occur.<br/>For Control of Hypertension: The usual adult starting dosage is 0.5 or 1.0g (10 to 20 mL) a day as a single or divided dose. Dosage is
increased or decreased according to blood pressure response. Rarely some patients
may require up to 2.0g (40 mL)
a day in divided doses.<br/>Infants and Children:<br/>For Diuresis and For Control of Hypertension: The usual pediatric dosage is 5 to 10 mg per pound (10
to 20 mg/kg) per day in single or two divided doses, not to exceed 375 mg
per day (2.5 to 7.5 mL or��to 1��teaspoonfuls of the oral
suspension daily) in infants up to 2 years of age or 1 g per day in children
2 to 12 years of age. In infants less than 6 months of age, doses up to 15 mg
per pound (30 mg/kg) per day in two divided doses may be required.

DIURIL(Chlorothiazide) is a diuretic and antihypertensive.
It is 6-chloro-2H-1,2,4-benzothiadiazine-7-sulfonamide
1,1-dioxide. Its empirical formula is CHClNOSand
its structural formula is: It is a white, or practically
white, crystalline powder with a molecular weight of 295.72, which is very
slightly soluble in water, but readily soluble in dilute aqueous sodium hydroxide.
It is soluble in urine to the extent of about 150 mg per 100 mL
at pH 7. Oral Suspension DIURIL contains 250 mg
of chlorothiazide per 5 mL, alcohol 0.5 percent, with methylparaben 0.12
percent, propylparaben 0.02 percent, and benzoic acid 0.1 percent added as
preservatives. The inactive ingredients are D&C Yellow 10, flavors,
glycerin, purified water, sodium saccharin, sucrose and tragacanth.

dailymed-instance:clinicalP... |
The mechanism of the antihypertensive effect of thiazides
is unknown. DIURIL does not usually affect normal blood pressure. DIURIL
affects the distal renal tubular mechanism of electrolyte reabsorption. At
maximal therapeutic dosage all thiazides are approximately equal in their
diuretic efficacy. DIURIL increases excretion of sodium
and chloride in approximately equivalent amounts. Natriuresis may be accompanied
by some loss of potassium and bicarbonate. After oral
use diuresis begins within 2 hours, peaks in about 4 hours and lasts about
6 to 12 hours.<br/>Pharmacokinetics and Metabolism: DIURIL is not metabolized but is eliminated rapidly by the
kidney. The plasma half-life of chlorothiazide is 45-120 minutes. After oral
doses, 10-15 percent of the dose is excreted unchanged in the urine. Chlorothiazide
crosses the placental but not the blood-brain barrier and is excreted in breast
milk.

General: All patients receiving diuretic therapy should be observed
for evidence of fluid or electrolyte imbalance: namely, hyponatremia, hypochloremic
alkalosis, and hypokalemia. Serum and urine electrolyte determinations are
particularly important when the patient is vomiting excessively or receiving
parenteral fluids. Warning signs or symptoms of fluid and electrolyte imbalance,
irrespective of cause, include dryness of mouth, thirst, weakness, lethargy,
drowsiness, restlessness, confusion, seizures, muscle pains or cramps, muscular
fatigue, hypotension, oliguria, tachycardia, and gastrointestinal disturbances
such as nausea and vomiting. Hypokalemia may develop,
especially with brisk diuresis, when severe cirrhosis is present or after
prolonged therapy. Interference with adequate oral electrolyte
intake will also contribute to hypokalemia. Hypokalemia may cause cardiac
arrhythmias and may also sensitize or exaggerate the response of the heart
to the toxic effects of digitalis (e.g., increased ventricular irritability).
Hypokalemia may be avoided or treated by use of potassium-sparing diuretics
orpotassium supplements such as foods with a high potassium content. Although
any chloride deficit is generally mild and usually does not require specific
treatment except under extraordinary circumstances (as in liver disease or
renal disease), chloride replacement may be required in the treatment of metabolic
alkalosis. Dilutional hyponatremia may occur in edematous
patients in hot weather; appropriate therapy is water restriction, rather
than administration of salt, except in rare instances when the hyponatremia
is life-threatening. In actual salt depletion, appropriate replacement is
the therapy of choice. Hyperuricemia may occur or acute
gout may be precipitated in certain patients receiving thiazides. In
diabetic patients dosage adjustments of insulin or oral hypoglycemic agents
may be required. Hyperglycemia may occur with thiazide diuretics. Thus latent
diabetes mellitus may become manifest during thiazide therapy. The
antihypertensive effects of the drug may be enhanced in the post-sympathectomy
patient. If progressive renal impairment becomes evident,
consider withholding or discontinuing diuretic therapy. Thiazides
have been shown to increase the urinary excretion of magnesium; this may result
in hypomagnesemia. Thiazides may decrease urinary calcium
excretion. Thiazides may cause intermittent and slight elevation of serum
calcium in the absence of known disorders of calcium metabolism. Marked hypercalcemia
may be evidence of hidden hyperparathyroidism. Thiazides should be discontinued
before carrying out tests for parathyroid function. Increases
in cholesterol and triglyceride levels may be associated with thiazide diuretic
therapy.<br/>Laboratory Tests: Periodic determination of serum electrolytes to detect possible
electrolyte imbalance should be done at appropriate intervals.<br/>Drug Interactions: When given concurrently the following drugs may interact
with thiazide diuretics. Alcohol,
barbiturates, or narcotics - potentiation of orthostatic hypotension
may occur. Antidiabetic
drugs (oral agents and insulin) - dosage adjustment of the
antidiabetic drug may be required. Other
antihypertensive drugs - additive effect or potentiation. Cholestyramine and colestipol resins -
Both cholestyramine and colestipol resins have the potential of binding thiazide
diuretics and reducing diuretic absorption from the gastrointestinal tract. Corticosteroids, ACTH - intensified electrolyte
depletion, particularly hypokalemia. Pressor
amines (e.g., norepinephrine) - possible decreased response
to pressor amines but not sufficient to preclude their use. Skeletal muscle relaxants, nondepolarizing (e.g., tubocurarine) -possible increased responsiveness to the muscle relaxant. Lithium - generally should not be given with
diuretics. Diuretic agents reduce the renal clearance of lithium and add a
high risk of lithium toxicity. Refer to the package insert for lithium preparations
before use of such preparations with DIURIL. Non-steroidal Anti-inflammatory Drugs -
In some patients, the administration of a non-steroidal anti-inflammatory
agent can reduce the diuretic, natriuretic, and antihypertensive effects of
loop, potassium-sparing and thiazide diuretics. Therefore, when DIURIL and
non-steroidal anti-inflammatory agents are used concomitantly, the patient
should be observed closely to determine if the desired effect of the diuretic
is obtained.<br/>Drug/Laboratory Interactions: Thiazides should be discontinued before carrying out tests
for parathyroid function (see PRECAUTIONS,
General).<br/>Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenicity studies have not been conducted with chlorothiazide. Chlorothiazide
was not mutagenic in vitro in the Ames
microbial mutagen test (using a maximum concentration of 5mg/plate and Salmonella typhimurium strains TA98 and TA100) and was not mutagenic and did not induce
mitotic nondisjunction in diploid-strains of Aspergillus
nidulans. Chlorothiazide had no adverse effects
on fertility in female rats at doses up to 60mg/kg/day and no adverse effects on fertility in male rats at doses
up to 40mg/kg/day. These doses are
1.5 and 1.0 timesthe recommended maximum human dose, respectively,
when compared on a body weight basis.<br/>Pregnancy:<br/>Teratogenic Effects:<br/>Nonteratogenic Effects: Chlorothiazide may cause fetal or neonatal jaundice, thrombocytopenia,
and possibly other adverse reactions which have occurred in the adult.<br/>Nursing Mothers: Because of the potential for serious adverse reactions in
nursing infants from DIURIL, a decision should be made whether to discontinue
nursing or to discontinue the drug, taking into account the importance of
the drug to the mother.<br/>Pediatric Use: There are no well-controlled clinical trials in pediatric
patients. Information on dosing in this age group is supported by evidence
from empiric use in pediatric patients and published literature regarding
the treatment of hypertension in such patients. (See DOSAGE
AND ADMINISTRATION, Infants and Children.)<br/>Geriatric Use: Clinical studies of DIURIL did not include sufficient numbers
of subjects aged 65 and over to determine whether they respond differently
from younger subjects. Other reported clinical experience has not identified
differences in responses between the elderly and younger patients. In general,
dose selection for an elderly patient should be cautious, usually starting
at the low end of the dosing range, reflecting the greater frequency of decreased
hepatic, renal, or cardiac function, and of concomitant disease or other drug
therapy. This drug is known to be substantially excreted
by the kidney, and the risk of toxic reactions to this drug may be greater
in patients with impaired renal function. Because elderly patients are more
likely to have decreased renal function, care should be taken in dose selection,
and it may be useful to monitor renal function .

dailymed-instance:overdosag... |
The most common signs and symptoms observed are those caused
by electrolyte depletion (hypokalemia, hypochloremia, hyponatremia) and dehydration
resulting from excessive diuresis. If digitalis has also been administered,
hypokalemia may accentuate cardiac arrhythmias. In the
event of overdosage, symptomatic and supportive measures should be employed.
Emesis should be induced or gastric lavage performed. Correct dehydration,
electrolyte imbalance, hepatic coma and hypotension by established procedures.
If required, give oxygen or artificial respiration for respiratory impairment. The
degree to which chlorothiazide sodium is removed by hemodialysis has not been
established. The oral LDof chlorothiazide
is 8.5g/kg, greater than 10g/kg, and greater than 1g/kg, in the mouse, rat and dog respectively.

|
dailymed-instance:warning |
Use with caution in severe renal disease. In patients with
renal disease, thiazides may precipitate azotemia. Cumulative effects of the
drug may develop in patients with impaired renal function. Thiazides
should be used with caution in patients with impaired hepatic function or
progressive liver disease, since minor alterations of fluid and electrolyte
balance may precipitate hepatic coma. Thiazides may
add to or potentiate the action of other antihypertensive drugs. Sensitivity
reactions may occur in patients with or without a history of allergy or bronchial
asthma. The possibility of exacerbation or activation
of systemic lupus erythematosus has been reported. Lithium
generally should not be given with diuretics (see PRECAUTIONS,
Drug Interactions).

dailymed-instance:indicatio... |
DIURIL is indicated as adjunctive therapy in edema associated
with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen
therapy. DIURIL has also been found useful in edema
due to various forms of renal dysfunction such as nephrotic syndrome, acute
glomerulonephritis, and chronic renal failure. DIURIL
is indicated in the management of hypertension either as the sole therapeutic
agent or to enhance the effectiveness of other antihypertensive drugs in the
more severe forms of hypertension. Use
in Pregnancy. Routine use of diuretics during normal pregnancy is
inappropriate and exposes mother and fetus to unnecessary hazard. Diuretics
do not prevent development of toxemia of pregnancy and there is no satisfactory
evidence that they are useful in the treatment of toxemia. Edema
during pregnancy may arise from pathologic causes or from the physiologic
and mechanical consequences of pregnancy. Thiazides are indicated in pregnancy
when edema is due to pathologic causes, just as they are in the absence of
pregnancy .
Dependent edema in pregnancy, resulting from restriction of venous return
by the gravid uterus, is properly treated through elevation of the lower extremities
and use of support stockings. Use of diuretics to lower intravascular volume
in this instance is illogical and unnecessary. During normal pregnancy there
is hypervolemia which is not harmful to the fetus or the mother in the absence
of cardiovascular disease. However, it may be associated with edema, rarely
generalized edema. If such edema causes discomfort, increased recumbency will
often provide relief.Rarely this edema may cause extreme discomfort which
is not relieved by rest. In these instances, a short course of diuretic therapy
may provide relief and be appropriate.
