used in pregnancy during the second and third trimesters, ACE inhibitors can
cause injury and even death to the developing fetus. When pregnancy is
detected, quinapril hydrochloride and hydrochlorothiazide should be discontinued
as soon as possible. See WARNINGS: Fetal/Neonatal Morbidity and
and hydrochlorothiazide is a fixed-combination tablet that combines an
angiotensin-converting enzyme (ACE) inhibitor, quinapril hydrochloride, and a
thiazide diuretic, hydrochlorothiazide.
QUINAPRIL AND HYDROCHLOROTHIAZIDE (QUINAPRIL/HYDROCHLOROTHIAZIDE) is indicated for the following:
DOSAGE AND ADMINISTRATION).
Angioedema in Black Patients: Black patients receiving ACE
inhibitor monotherapy have been reported to have a higher incidence of
angioedema compared to non-blacks. It should also be noted that in controlled
clinical trials, ACE inhibitors have an effect on blood pressure that is less in
black patients than in non-blacks.

Quinapril for treatment of hypertension in Turkey: dose titration and diuretic combination treatment strategies. 
BACKGROUND and objective: Recently the PatenT (Prevalence, awareness, treatment and control of hypertension in Turkey) study showed that while the prevalence of hypertension in Turkey is high, effective control of BP is infrequently achieved. This study investigated the efficacy and safety of quinapril (as monotherapy or in combination with hydrochlorothiazide [HCTZ]) for achieving BP control (target <140/90 mm Hg) in Turkish subjects with mild to moderate hypertension... CONCLUSION: Quinapril was an effective and safe treatment for achieving and maintaining recommended BP targets in this sample population. These findings will provide clinicians in Turkey with valuable data on the use of quinapril for effective control and management of hypertension.
Beneficial effects of add-on hydrochlorothiazide in rats with myocardial infarction optimally treated with quinapril. [2005.12]
BACKGROUND: The antihypertensive and renoprotective effects of ACE inhibitor (ACEi) therapy are enhanced by inducing a negative sodium balance. Whether this strategy also improves outcome of chronic ACEi treatment after myocardial infarction (MI) is unknown. Therefore, we investigated whether hydrochlorothiazide (HCTZ) or dietary sodium restriction further improves survival in ACEi-treated rats with MI... CONCLUSIONS: Adding HCTZ, but not LS, to quinapril improved survival, neurohumoral status, and proteinuria during the early chronic phase of experimental post-MI LV dysfunction. Since no adverse effects were observed, HCTZ may safely be used to improve ACEi therapy.
