Composition:
Each tablet contains:
Spironolactone (USP) ............. 25 mg
Hydrochlorothiazide (USP) ...... 25 mg
Properties:
Spirozide is a combination of 2 diuretics agents with
complementary modes of action:
Hydrochlorothiazide promotes water and
sodium excretion by primary inhibition of
their reabsorption at the distal tubules.
Spironolactone acts specifically by
inhibiting aldosterone receptors at the
distal tubules.
Both actions lead to diuresis. In addition,
spironolactone minimizes potassium excretion
and helps its retention in the body.
Indications:
Edema associated with congestive heart
failure, nephrotic syndrome, liver cirrhosis
with ascites & idiopathic edema.
Essential Hypertension.
Contraindications:
► Significant renal impairment
► Hyperkalemia
► Acute renal failure
► Acute hepatic failure
Precautions:
Patient should be evaluated for possible fluid &
electrolyte disturbances, dehydration,
circulatory collapse, vertigo, hypotension
and lethargy.
Spirozide may raise BUN levels and cause
mild acidosis in patients with impaired
renal function.
Spirozide increases the half-life of
digitalis, resulting in possible digitalis
toxicity. Therefore, the dose of digitalis
should be reduced accordingly.
Spirozide may temporarily exaggerate
abnormalities of glucose metabolism.
Spirozide reduces the vascular
responsiveness to noradrenaline. Therefore,
caution should be exercised in managing
patients subjected to anesthesia while being
treated.
Thiazides were shown to alter metabolism of
uric acid, precipitating high level in
blood.
Warning:
Spirozide should not be taken with other potassium
sparing diuretics to avoid hyperkalemia.
Thiazides have been reported to exacerbate
systemic lupus erythematosus.
Dosage & route of administration & duration:
Edema: 4 tablets / day in divided doses.
Hypertension: 2 - 4 tablets / day in divided doses.
Children: 0.35 - 0.7 mg / kg body weight / day, in divided doses.
Use in pregnancy & lactation:
Spirozide may cross placental barrier and cause fetal
hazards. Necessity of the drug should be
weighed against this risk.
Spirozide may appear in milk of
breast-feeding mothers, if necessary
artificial feeding should be sought.
Side effects:
Side effects are reversible and disappear after the drug

vomiting, abdominal cramps, hypotension,
fatigue, dry mouth, dizziness, pruritis and

have been
reported. Gynaecomastia may occur.
