Quinapril and Hydrochlorothiazide (Quinapril Hydrochloride / Hydrochlorothiazide) - Summary

 
 



USE IN PREGNANCY

When 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 Mortality.

 

SUMMARY

QUINAPRIL HYDROCHLORIDE
and
HYDROCHLOROTHIAZIDE TABLETS
10 mg/12.5 mg, 20 mg/12.5 mg and 20 mg/25 mg*

Quinapril HCl/hydrochlorothiazide tablets are fixed-combination tablets that combine an angiotensin-converting enzyme (ACE) inhibitor, quinapril hydrochloride, and a thiazide diuretic, hydrochlorothiazide.

Quinapril HCl/hydrochlorothiazide tablets are indicated for the treatment of hypertension.  This fixed combination is not indicated for the initial therapy of hypertension (see DOSAGE AND ADMINISTRATION).

In using quinapril HCl/hydrochlorothiazide tablets, consideration should be given to the fact that another angiotensin-converting enzyme inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen-vascular disease. Available data are insufficient to show that quinapril does not have a similar risk (see WARNINGS: Neutropenia/Agranulocytosis).

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.

Published Studies Related to Quinapril and Hydrochlorothiazide (Quinapril / Hydrochlorothiazide)

Quinapril for treatment of hypertension in Turkey: dose titration and diuretic combination treatment strategies. [2007]
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.

Clinical Trials Related to Quinapril and Hydrochlorothiazide (Quinapril / Hydrochlorothiazide)

A Study to Evaluate the Efficacy and Safety of Quinapril or Quinapril Plus Hydrochlorothiazide in Patients With Mild to Moderate Hypertension [Completed]
The purpose of this study is to determine the response rate for the therapeutic goal (diastolic blood pressure (BP) less than 90 mmHg and systolic BP less than 140 mmHg) at Week 6 for quinapril 20 mg and at Week 12 for quinapril 20 mg, quinapril 40 mg, and quinapril 20 mg plus hydrochlorothiazide 12. 5 mg; and to determine the mean decrease in diastolic and systolic BP measurements and the change in heart rate at Week 6 and Week 12 compared with baseline.

High-Dose Quinapril Versus Low-Dose Quinapril Plus Amlodipine in the Treatment of High-Risk Hypertensive Patients [Terminated]
The purpose of this study is to compare the impact of two blood pressure lowering treatments (high dose quinapril versus low dose quinapril plus amlodipine) on variations in heart rate over 24 hours.

Fasting Study of Quinapril Hydrochloride Tablets 40 mg and AccuprilŽ Tablets 40 mg [Completed]
The objective of this study was to investigate the bioequivalence of Mylan quinapril hydrochloride 40 mg tablets compared to Parke-Davis AccuprilŽ 40 mg tablets following a single, oral 40 mg (1 x 40 mg) dose under fasting conditions.

Food Study of Quinapril Hydrochloride Tablets 40 mg and AccuprilŽ Tablets 40 mg [Completed]
The objective of this study was to investigate the bioequivalence of Mylan quinapril hydrochloride 40 mg tablets compared to Parke-Davis AccuprilŽ 40 mg tablets following a single, oral 40 mg (1 x 40 mg) dose under fed conditions.

Non-Comparative Study To Evaluate Changes In FMD After Quinapril Therapy In Hypertensive Women [Completed]
ACE inhibitors are thought to modify the endothelium in a number of ways. Quinapril is an effective and well-tolerated ACE-I for the treatment of patients with hypertension and congestive heart failure. Quinapril produces favourable haemodynamic changes and improves ventricular and endothelial function in patients with various cardiovascular disorders. These effects are mediated through the binding of quinaprilat to both tissue and plasma-ACE.

Quinapril 10 to 40 mg once daily improved endothelial function (as measured by improved FMD or reduced vasoconstrictive/increased vasodilative response to Ach) in patients with CAD and hypertension over 2 to 6 months of therapy; improved endothelial function was also observed in patients with CHF receiving a single infusion of quinaprilat. In general, quinapril showed neutral or beneficial effects on lipid profiles, glycaemia and renal haemodynamics. (3) There are no data available considering effects of quinapril on endothelial dysfunction in post- menopausal woman with mild to moderate hypertension and with pathological endothelial function.
