PHARMACOLOGICAL CLASSIFICATION
A 7.1.3 Other hypotensives.
PHARMACOLOGICAL ACTION
Lisinopril/HCT is a combination of an angiotensin converting
enzyme inhibitor, lisinopril and a diuretic,
hydrochlorothiazide. Both these
components have been widely used
alone and in combination for the treatment of hypertension due
to additive effects. Lisinopril is a peptidyl dipeptidase
inhibitor and inhibits the angiotensin converting enzyme (ACE)
that catalyses the conversion of angiotensin I to angiotensin
II. Angiotensin II is a vasoconstrictor peptide which also
stimulates aldosterone secretion by the adrenal cortex.
Inhibition of ACE results in decreased concentrations of
angiotensin II which results in decreased vasopressor activity
and reduced aldosterone secretion. Reduced aldosterone secretion
may result in an increase in serum potassium concentration.
The mechanism of action through which lisinopril lowers blood
pressure is mainly via suppression of the
renin-angiotensin-aldosterone system; however lisinopril also
has antihypertensive effects in patients with low-renin
hypertension.
ACE is identical to kininase II, an enzyme that degrades
bradykinin. It could be possible that increased levels of
bradykinin, a potent vasodilatory peptide, play a role in the
therapeutic effects of lisinopril. However, this remains to be
elucidated.
Hydrochlorothiazide is a thiazide diuretic and an
antihypertensive agent. It affects the distal renal tubular
mechanism of electrolyte re-absorption and increases excretion
of sodium and chloride in approximately equivalent amounts.
Natriuresis may be accompanied by some loss of potassium and
bicarbonate. The mechanism of the antihypertensive effects of
the thiazides is unknown. Thiazides do not usually affect normal
blood pressure.
Pharmacokinetics
The concomitant administration of lisinopril and
hydrochlorothiazide has no clinical significant effect on the
pharmacokinetics of either drug.
Lisinopril
Approximately 60% of lisinopril is absorbed after oral
administration. The absorption varies between individuals (6 to
60%).
Following oral administration of lisinopril, peak serum
concentrations occur within about 7 hours. Lisinopril has an
effective half-life of 12 hours. Lisinopril does not bind to
other serum proteins.
The absorption of lisinopril is not affected by the presence of
food in the
gastrointestinal tract.
Lisinopril does not undergo metabolism and absorbed drug is
excreted unchanged entirely in the urine. Impaired renal
function decreases elimination of lisinopril. This decrease only
becomes clinically important when the glomerular filtration rate
is below 30 mL/min. Lisinopril can be removed by dialysis.
Older patients have higher blood levels and higher values for
the area under the plasma concentration time curve than younger
patients.
Hydrochlorothiazide
The plasma half-life of hydrochlorothiazide can vary between
5 and 15 hours. Approximately 60% of the dose is eliminated
unchanged within 24 hours.
After oral administration of hydrochlorothiazide, diuresis
begins within 2 hours, peaks in about 4 hours and lasts 6 to
12 hours.
INDICATIONS
Mild to moderate hypertension in patients who have been
stabilized on their individual components given in the same
proportions.
CONTRA INDICATIONS
Anuria.
Hypersensitivity to any component of this product.
Patients with a history of angioedema relating to previous
treatment with an angiotensin-converting enzyme inhibitor.
Patients with hereditary or idiopathic angioedema (see Special
Precautions). Hypersensitivity to other sulphonamide-derived
medicines.
Pregnancy and Breast feeding Mothers - see Pregnancy and
Lactation. Patients with aortic stenosis or hypertrophic
cardiomyopathy.
Bilateral renal artery stenosis or unilateral renal artery
stenosis in the presence of a single kidney.
WARNINGS
Should a woman become pregnant while receiving Lisinopril
And Hydrochlorothiazide, the treatment must be stopped
immediately and switched to an alternative medicine. Should a
woman contemplate pregnancy, an alternative antihypertensive
medication should be used.
DOSAGE AND DIRECTIONS FOR USE
The usual dosage is one tablet daily, taken at approximately
the same time each day. It is recommended that if the desired
clinical effect cannot be achieved within 2 to 4 weeks with this
dosage, the dosage may be increased to a maximum of two tablets,
administered once daily.
Prior Treatment with Diuretics
Symptomatic hypotension may occur after the initial dose of
Lisinopril And Hydrochlorothiazide; this phenomenon occurs more
likely in patients who are volume and/or salt depleted as a
result of prior diuretic therapy. If possible, the diuretic
therapy should be discontinued for 2-3 days prior to initiation
of therapy with Lisinopril And Hydrochlorothiazide; or if this
is not possible, lisinopril should be given alone at a low
initial dose of 5 mg.
Renal Impairment
Thiazides may not be suitable diuretics for use in patients
with renal impairment and are ineffective in moderate or severe
renal impairment (creatinine clearance values of 30 mL/min or
below).
Lisinopril And Hydrochlorothiazide should not be used as initial
therapy in any patient with renal insufficiency.
In patients with creatinine clearance of >30 and <80 mL/min,
Lisinopril And Hydrochlorothiazide may be used, but only after
titration of the individual components.
Use in children
Safety and efficacy in children have not been established.
Use in the Elderly
There are no significant differences in the efficacy and
tolerability to lisinopril and hydrochlorothiazide, administered
concomitantly, between elderly and younger hypertensive
patients.
INTERACTIONS
Serum Potassium
The decrease in potassium caused by thiazide diuretics is
usually attenuated by the effect of lisinopril. The use of
potassium supplements, potassium-sparing agents or
potassium-containing salt substitutes, especially in patients
with impaired renal function, may result in a significant
increase in serum potassium. Should it be required to administer
Lisinopril And Hydrochlorothiazide concomitantly with any of
these agents, caution should be exercised and serum potassium
should be monitored on a regular basis.
Lithium
The concomitant use of lithium with diuretics or
ACE-inhibitors is not indicated. The renal clearance of lithium
is reduced by ACE-inhibitors and diuretic agents and a high risk
of lithium toxicity exists. The prescribing information for
lithium preparation should be reviewed before use of these
preparations.
Non-steroidal anti-inflammatory drugs (NSAIDs)
Indomethacin may decrease the antihypertensive efficacy of
Lisinopril And Hydrochlorothiazide. In some patients with
compromised renal function who are being treated with
non-steroidal anti-inflammatory drugs (NSAIDs), the
co-administration of lisinopril may result in a further
deterioration in renal function.
The administration of a non-steroidal anti-inflammatory agent
can reduce the diuretic, natriuretic and antihypertensive
effects of diuretics in some patients.
Tubocurarine
Thiazides may increase the responsiveness to tubocurarine.
Other Antihypertensive Agents
Additive effects may occur.
Alcohol, barbiturates or narcotics
Potentiation of orthostatic hypotension caused by thiazides
may occur.
Antidiabetic medicine (oral agents and insulin)
Dosage adjustment of the antidiabetic medicine may be required
with the concomitant use of a thiazide diuretic.
Corticosteroids, ACTH
Concomitant use of a thiazide diuretic may intensify
electrolyte depletion and hypokalaemia.
Pressor Amines (e.g. adrenalin):
Thiazide diuretics may decrease response to pressor amines.
This decrease in response is not sufficient to prelude the use
of pressor amines.

PREGNANCY AND LACTATION
Safety in pregnancy and lactation has not been established.
Refer to WARNINGS. Lisinopril And Hydrochlorothiazide can cause
foetal and neonatal morbidity and mortality when administered to
pregnant women during the 2nd and 3rd
trimesters. Lisinopril And Hydrochlorothiazide
passes through
the placenta and can be presumed to cause disturbance in foetal
blood regulatory mechanisms.
Use of Lisinopril And Hydrochlorothiazide during the second and
third trimester has been associated with foetal and neonatal
injury including hypotension, renal failure, hyperkalaemia,
oliguria, anuria and skull hypoplasia in the newborn. Maternal
oligohydramnios, presumably representing decreased foetal renal
function, has occurred and may result in limb contractures,
craniofacial deformations and hypoplastic lung development.
Prematurity and low birth mass can occur. These adverse effects
to the embryo and foetus do not appear to have resulted from
intrauterine ACE-inhibitor exposure limited to the first
trimester.
Infants whose mothers have taken Lisinopril And
Hydrochlorothiazide should be closely observed for hypotension,
oliguria and hyperkalaemia. Lisinopril, which crosses the
placenta, has been removed from the neonatal circulation by
peritoneal dialysis with some clinical benefit. There is no
experience with the removal of hydrochlorothiazide, which also
crosses the placenta, from the neonatal circulation.
The routine use of diuretics in otherwise healthy pregnant woman
is not recommended and exposes mother and foetus to unnecessary
hazard. Diuretics do not prevent development of toxaemia of
pregnancy and there is no satisfactory evidence that they are
useful in the treatment of toxaemia. Thiazides cross the
placental barrier and appear in cord blood. Hazards include
foetal or neonatal jaundice, thrombocytopenia and possibly other
adverse reactions which occur in the adult.
Breast-feeding
It is not known whether lisinopril is distributed into human
breast milk; however the thiazides do appear in human milk. If
the drug is deemed essential, the patient should stop nursing.

arthralgia/arthritis, a positive Antinuclear antibody (ANA),
elevated erythrocyte sedimentation rate, eosinophilia and
leukocytosis.
Lisinopril: Stevens-Johnson Syndrome
Laboratory Test Findings
Hyperkalaemia, hyperglycaemia and hyperuricaemia and have
been noted. Increases in serum creatinine and in blood urea
nitrogen have been reported in patients without renal
impairment. These are usually reversible if medication is
discontinued.
Bone marrow depression manifesting as anaemia and/or
thrombocytopenia and/or leucopenia have also occurred.
Agranulocytosis has been reported.
Small decreases in haemoglobin and haematocrit have been
reported frequently in hypertensive patients treated with
Lisinopril And Hydrochlorothiazide but were rarely of clinical
significance unless another cause of anaemia was also present.
Elevations of liver enzymes (AST and ALT) and/or serum bilirubin
have been reported.
Special Precautions
Hypotension and Electrolyte/Fluid Imbalance
Symptomatic hypotension may occur in the patients with the
following: fluid or electrolyte imbalance, e.g. volume
depletion, hyponatraemia, hypochloraemic alkalosis,
hypomagnesaemia or hypokalaemia which may occur from prior
treatment with diuretics, a salt restricted diet, dialysis, or
after severe diarrhoea and repeated vomiting.
Determination of serum electrolytes should be performed at
appropriate intervals in such patients.
Initiation of treatment and dose adjustment should be monitored
under close medical supervision in patients with an increased
risk of symptomatic hypotension. Special consideration should be
given when this medication is administered to patients with
ischemic heart or cerebrovascular disease as an excessive
decrease in blood pressure could result in a myocardial
infarction or cerebrovascular accident.
If hypotension occurs, the patient should be placed in the
supine position and, if necessary, should receive an intravenous
infusion of 0,9% saline. A transient hypotensive response does
not warrant discontinuation of further doses.
Once effective blood volume and pressure have been stabilised,
therapy at a reduced dosage may be reinstituted; or
alternatively either of the components may be used appropriately
as monotherapy.
Renal Insufficiency
Thiazides may not be suitable diuretics for use inpatients
with renal impairment and are ineffective at creatinine
clearance values of 30 mL/min or below (i.e. moderate or severe
renal insufficiency.)
Lisinopril And Hydrochlorothiazide should not be administered to
patients with a creatinine clearance < 80 mL/min until
titration of the individual components has shown the need for
the doses present in Lisinopril And Hydrochlorothiazide.
In some patients with bilateral renal artery stenosis or
stenosis of the artery to a solitary kidney, who have received
ACE inhibitor treatment, increases in blood urea and serum
creatinine, usually reversible upon discontinuation of therapy,
have been seen. This is especially likely to occur in patients
with renal insufficiency.
Some hypertensive patients with no apparent pre-existing renal
disease
have developed increases in blood urea and serum creatinine when lisinopril has been given concomitantly with a
diuretic. If this occurs during therapy with, it should be
discontinued. Reinstitution of therapy at a reduced dosage may
be possible: or either of the components may be used alone as
appropriate.
Haemodialysis
The use of Lisinopril And Hydrochlorothiazide is not
indicated in patients requiring dialysis for renal failure.
Anaphylactoid reactions have been reported in patients
undergoing haemodialysis procedures with certain dialysis
membranes (e.g. with the high-flux membranes) and concurrent
treatment with Lisinopril And Hydrochlorothiazide Consideration
to the use of a different type of dialysis membrane or a
different class of anti hypertensive agent should be given in
these patients.
Hepatic Disease
Caution should be exercised when thiazides are used in
patients with hepatic impairment or progressive liver disease,
as minor alterations of fluid and electrolyte balance may
precipitate hepatic coma in these patients.
Surgery/Anaesthesia
In patients undergoing major surgery or during anaesthesia
with agents that produce hypotension, lisinopril may block
angiotensin II formation secondary to compensatory renin
release. Should hypotension occur, and is considered to be due
to this mechanism, it can be corrected by volume expansion.
Metabolic and Endocrine Effects
Thiazide diuretics may impair glucose tolerance. Dosage
adjustment of antidiabetic agents, including insulin, may be
required.
Decreased urinary calcium excretion caused by thiazides may
result in intermittent and a slightly raised serum calcium
concentration. Should marked hypercalcaemia occur, it may be
evidence of underlying hyperparathyroidism. Lisinopril And
Hydrochlorothiazide therapy should be discontinued before
carrying out tests for parathyroid function (see Interactions).
Increased cholesterol and triglyceride levels may be a result of
thiazide diuretic therapy.
Thiazide diuretics may precipitate hyperuricaemia and/or gout in
certain patients. Due to the increase in urinary uric acid
caused by lisinopril, hyperuricaemia may be attenuated by
Lisinopril And Hydrochlorothiazide which contains both
components.
Sensitivity/Angioedema
Angioedema of the face, extremities, lips, tongue, glottis
and/or larynx has been reported in patients with angiotensin-converting
enzyme inhibitors, including lisinopril. In such cases
Lisinopril And Hydrochlorothiazide should be discontinued
immediately and appropriate measures should be instituted to
ensure complete resolution of symptoms prior to dismissing the
patient. In instances where swelling has been confined only to
the face and lips, the condition usually resolves without
treatment, although antihistamines have been useful in relieving
symptoms.
Angioedema associated with laryngeal oedema may be fatal. Where
there is involvement of the tongue, glottis or larynx, likely to
cause airway obstruction, appropriate emergency therapy should
be administered promptly. This may include the administration of
adrenaline and/or maintenance of a patients airway. The patient
should be under close medical supervision until complete and
sustained resolution of symptoms
has occurred. These patients
should never receive any Lisinopril And Hydrochlorothiazide
again.
Patients with a history of angioedema unrelated to
Lisinopril And Hydrochlorothiazide therapy may be at increased
risk of angioedema while receiving Lisinopril And
Hydrochlorothiazide (see also Contra-indications).
In patients receiving thiazides, sensitivity reactions may occur
with or without a history of allergy or bronchial asthma.
Exacerbation or activation of systemic lupus erythematosus has
been reported with the use of thiazides.
Race
Lisinopril And Hydrochlorothiazide causes a higher rate of
angioedema in black patients than in non-black patients.
Desensitisation
Patients receiving ACE-inhibitors during desensitisation
treatment (e.g. hymenoptera venom) have sustained anaphylactoid
reactions. These reactions have been avoided when ACE-inhibitors
were temporarily withheld but they reappeared upon inadvertant
rechallenge.
Cough
A non-productive, persistent cough has been reported with
the use of ACE-inhibitors. The cough resolves after
discontinuation of therapy. ACE-inhibitor-induced cough should
be considered as part of the differential diagnosis of cough.
KNOWN SYMPTOMS OF OVERDOSAGE AND PARTICULARS OF ITS
TREATMENT:
Treatment is symptomatic and supportive. No specific
information is available on the treatment of overdosage with
Lisinopril And Hydrochlorothiazide. Therapy with Lisinopril And
Hydrochlorothiazide should be discontinued and the patient
should be kept under very close supervision. Suggested measures
include induction of emesis and/or gastric lavage, if ingestion
is recent, and correction of dehydration, electrolyte imbalance
and hypotension by established procedures.
Lisinopril:The most likely features of overdosage may
include hypotension, electrolyte disturbance and renal failure.
Treatment is symptomatic and supportive.
Hydrochlorothiazide:The most common signs and symptoms
observed are those caused by electrolyte depletion (hypokalaemia,
hypochloraemia, hyponatraemia) and dehydration resulting from
excessive diuresis. If digitalis has been used concomitantly,
hypokalaemia may accentuate cardiac arrhythmias.
