ADVERSE REACTIONS
Quinapril hydrochloride
and hydrochlorothiazide has been evaluated for safety in 1571 patients in
controlled and uncontrolled studies. Of these, 498 were given quinapril plus
hydrochlorothiazide for at least 1 year, with 153 patients extending combination
therapy for over 2 years. In clinical trials with quinapril hydrochloride and
hydrochlorothiazide, no adverse experience specific to the combination has been
observed. Adverse experiences that have occurred have been limited to those that
have been previously reported with quinapril or hydrochlorothiazide.
Adverse experiences were
usually mild and transient, and there was no relationship between side effects
and age, sex, race, or duration of therapy. Discontinuation of therapy because
of adverse effects was required in 2.1% in patients in controlled studies. The
most common reasons for discontinuation of therapy with quinapril hydrochloride
and hydrochlorothiazide were cough (1%; see PRECAUTIONS)
and headache (0.7%).
Adverse experiences
probably or possibly related to therapy or of unknown relationship to therapy
occurring in 1% or more of the 943 patients treated with quinapril plus
hydrochlorothiazide in controlled trials are shown below.

Quinapril monotherapy
has been evaluated for safety in 4960 patients. In clinical trials adverse
events which occurred with quinapril were also seen with quinapril hydrochloride
and hydrochlorothiazide. In addition, the following were reported for quinapril
at an incidence greater than 0.5%: depression, back pain, constipation, syncope, and
amblyopia.
Hydrochlorothiazide has
been extensively prescribed for many years, but there has not been enough
systematic collection of data to support an estimate of the frequency of the
observed adverse reactions. Within organ-system groups, the reported reactions
are listed here in decreasing order of severity, without regard to frequency.

Orthostatic hypotension (may be potentiated by alcohol,
|

Clinical Laboratory Test Findings
Serum
Electrolytes: See PRECAUTIONS.
Creatinine, Blood Urea Nitrogen: Increases (greater than 1.25 times
the upper limit of normal) in serum creatinine and blood urea nitrogen were
observed in 3% and 4%, respectively, of patients treated with quinapril
hydrochloride and hydrochlorothiazide. Most increases were minor and reversible,
which can occur in patients with essential hypertension but most frequently in
patients with renal artery stenosis (see PRECAUTIONS).
PBI and
Tests of Parathyroid Function: See PRECAUTIONS.
Hematology: See WARNINGS.
Other
(causal relationships unknown): Other clinically important changes in
standard laboratory tests were rarely associated with quinapril hydrochloride
and hydrochlorothiazide administration. Elevations in uric acid, glucose,
magnesium, cholesterol, triglyceride, and calcium (see PRECAUTIONS) have been reported.
