🩺 Clinical
The combination of benazepril and hydrochlorothiazide is used to treat high blood pressure. Benazepril is in a class of medications called angiotensin-converting enzyme (ACE) inhibitors. It works by decreasing certain chemicals that tighten the blood vessels, so blood flows more smoothly. Hydrochlorothiazide is in a class of medications called diuretics ('water pills'). It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine. High blood pressure is a common condition, and when not treated it can cause damage to the brain, heart, blood vessels, kidneys...

🎯 Indications and Usage ▾
INDICATIONS AND USAGE Benazepril HCl and Hydrochlorothiazide is indicated for the treatment of hypertension. This fixed combination drug is not indicated for the initial therapy of hypertension (see DOSAGE AND ADMINISTRATION ) .
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION Dose once daily. The dosage may then be increased after 2 to 3 weeks as needed to help achieve blood pressure goals. The maximum recommended dose is 20/25 mg.
Switch Therapy: A patient whose blood pressure is not adequately controlled with benazepril alone or with hydrochlorothiazide alone may be switched to combination therapy with Benazepril HCl and Hydrochlorothiazide. The usual recommended starting dose is 10/12.5 mg once daily to control blood pressure. Replacement Therapy: The combination may be substituted for the titrated individual components.
⛔ Contraindications ▾
CONTRAINDICATIONS Benazepril HCl and Hydrochlorothiazide is contraindicated in patients who are anuric. Benazepril HCl and Hydrochlorothiazide is also contraindicated in patients who are hypersensitive to benazepril, to any other ACE inhibitor, to hydrochlorothiazide, or to other sulfonamide-derived drugs. Hypersensitivity reactions are more likely to occur in patients with a history of allergy or bronchial asthma.
Benazepril HCl and Hydrochlorothiazide is also contraindicated in patients with a history of angioedema with or without previous ACE inhibitor treatment. Benazepril HCl and Hydrochlorothiazide is contraindicated in combination with a neprilysin (e.g., sacubitril). Do not administer Benazepril HCl and Hydrochlorothiazide within 36 hours of switching to or from sacubitril/valsartan a neprilysin inhibitor (see WARNINGS and PRECAUTIONS ) .
Do not coadminister aliskiren with angiotensin receptor blockers, ACE inhibitors, including Benazepril HCl and Hydrochlorothiazide in patients with diabetes.
⚠️ Warnings ▾
WARNINGS Anaphylactoid and Possibly Related Reactions Presumably because angiotensin-converting enzyme inhibitors affect the metabolism of eicosanoids and polypeptides, including endogenous bradykinin, patients receiving ACE inhibitors (including benazepril) may be subject to a variety of adverse reactions, some of them serious. Head and Neck Angioedema: Angioedema of the face, extremities, lips, tongue, glottis, and larynx has been reported in patients treated with angiotensin-converting enzyme inhibitors. In U.S. clinical trials, symptoms consistent with angioedema were seen in none of the subjects who received placebo and in about 0.5% of the subjects who received benazepril.
Angioedema associated with laryngeal edema can be fatal. If laryngeal stridor or angioedema of the face, tongue, or glottis occurs, treatment with Benazepril HCl and Hydrochlorothiazide should be discontinued and appropriate therapy instituted immediately. When involvement of the tongue, glottis, or larynx appears likely to cause airway obstruction, appropriate therapy, e.g., subcutaneous epinephrine injection 1:1000 (0.3 - 0.5 mL) should be promptly administered (see PRECAUTIONS and ADVERSE REACTIONS ).
Black patients receiving ACE inhibitors have been reported to have a higher incidence of angioedema compared to nonblacks. Patients receiving coadministration of ACE inhibitor and mTOR (mammalian target of rapamycin) inhibitor (e.g., temsirolimus, sirolimus, everolimus) therapy or a neprilysin inhibitor may be at increased risk for angioedema (see PRECAUTIONS ) . Intestinal Angioedema: Intestinal angioedema has been reported in patients treated with ACE inhibitors.
These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no prior history of facial angioedema and C-1 esterase levels were normal. The angioedema was diagnosed by procedures including abdominal CT scan or ultrasound, or at surgery, and symptoms resolved after stopping the ACE inhibitor. Intestinal angioedema should be included in the differential diagnosis of patients on ACE inhibitors presenting with abdominal pain.
Anaphylactoid Reactions During Desensitization: Two patients undergoing desensitizing treatment with hymenoptera venom while receiving ACE inhibitors sustained life-threatening anaphylactoid reactions. In the same patients, these reactions were avoided when ACE inhibitors were temporarily withheld, but they reappeared upon inadvertent rechallenge. Anaphylactoid Reactions During Membrane Exposure: Anaphylactoid reactions have been reported in patients dialyzed with high-flux membranes and treated concomitantly with an ACE inhibitor.
Anaphylactoid reactions have also been reported in patients undergoing low density lipoprotein apheresis with dextran sulfate absorption. Hypersensitivity reactions to hydrochlorothiazide are more likely in patients with allergy and asthma. Hypotension Benazepril HCl and Hydrochlorothiazide can cause symptomatic hypotension.
Like other ACE inhibitors, benazepril has been only rarely associated with hypotension in uncomplicated hypertensive patients. Symptomatic hypotension is most likely to occur in patients who have been volume and/or salt depleted as a result of prolonged diuretic therapy, dietary salt restriction, dialysis, diarrhea, or vomiting. Volume and/or salt depletion should be corrected before initiating therapy with Benazepril HCl and Hydrochlorothiazide.
Benazepril HCl and Hydrochlorothiazide should be used cautiously in patients receiving concomitant therapy with other antihypertensives. The thiazide component of Benazepril HCl and Hydrochlorothiazide may potentiate the action of other antihypertensive drugs, especially ganglionic or peripheral adrenergic-blocking drugs. The antihypertensive effects of the thiazide component may also be enhanced in the postsympathectomy patient.

🤒 Adverse Reactions ▾
ADVERSE REACTIONS Benazepril HCl and Hydrochlorothiazide has been evaluated for safety in over 2500 patients with hypertension; over 500 of these patients were treated for at least 6 months, and over 200 were treated for more than 1 year. The reported side effects were generally mild and transient, and there was no relationship between side effects and age, sex, race, or duration of therapy. Discontinuation of therapy due to side effects was required in approximately 7% of U.S. patients treated with Benazepril HCl and Hydrochlorothiazide and in 4% of patients treated with placebo.
The most common reasons for discontinuation of therapy with Benazepril HCl and Hydrochlorothiazide in U.S. studies were cough (1.0%; see PRECAUTIONS ), “dizziness” (1.0%), headache (0.6%), and fatigue (0.6%). The side effects considered possibly or probably related to study drug that occurred in U.S. placebo-controlled trials in more than 1% of patients treated with Benazepril HCl and Hydrochlorothiazide are shown in the table below.

0.4Other side effects considered possibly or probably related to study drug that occurred in U.S. placebo-controlled trials in 0.3% to 1.0% of patients treated with Benazepril HCl and Hydrochlorothiazide were the following: Cardiovascular: Palpitations, flushing. Gastrointestinal: Vomiting, diarrhea, dyspepsia, anorexia, and constipation. Neurologic and Psychiatric: Insomnia, nervousness, paresthesia, libido decrease, dry mouth, taste perversion, and tinnitus.
Dermatologic: Rash and sweating. Other: Urinary frequency, arthralgia, myalgia, asthenia, and pain (including chest pain and abdominal pain). Other adverse experiences reported in 0.3% or more of Benazepril HCl and Hydrochlorothiazide patients in U.S. controlled clinical trials, and rarer events seen in post-marketing experience, were the following; asterisked entries occurred in more than 1% of patients (in some, a causal relationship to Benazepril HCl and Hydrochlorothiazide is uncertain): Cardiovascular: Syncope, peripheral vascular disorder, and tachycardia.
Body as a Whole: Infection, back pain*, flu syndrome*, fever, chills, and neck pain. Dermatologic: Photosensitivity and pruritus. Gastrointestinal: Gastroenteritis, flatulence, and tooth disorder.
Neurologic and Psychiatric: Hypesthesia, abnormal vision, abnormal dreams, and retinal disorder. Respiratory: Upper respiratory infection*, epistaxis, bronchitis, rhinitis*, sinusitis*, and voice alteration. Other: Conjunctivitis, arthritis, urinary tract infection, alopecia, and urinary frequency*.
Post-Marketing Experience The following adverse reactions have been identified during post-approval use of either benazepril or hydrochlorothiazide. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure: Non-melanoma Skin Cancer: Hydrochlorothiazide is associated with an increased risk of non-melanoma skin cancer. In a study conducted in the Sentinel System, increased risk was predominantly for squamous cell carcinoma (SCC) and in white patients taking large cumulative doses.
The increased risk for SCC in the overall population was approximately 1 additional case per 16,000 patients per year, and for white patients taking a cumulative dose of ≥50,000mg the risk increase was approximately 1 additional SCC case for every 6,700 patients per year.

🔄 Drug Interactions ▾
Drug Interactions Neprilysin Inhibitors: Patients taking concomitant neprilysin may be at increased risk for angioedema. Interactions Common for Both Benazepril and Hydrochlorothiazide Potassium Supplements and Potassium Sparing Diuretics: Concomitant use with Benazepril HCl and Hydrochlorothiazide may effect potassium levels. Monitor potassium periodically. mTOR (mammalian target of rapamycin) inhibitors: Patients receiving coadministration of ACE inhibitor and mTOR inhibitor (e.g., tesmsirolimus, sirolimus, everolimus) therapy may be at increased risk for angioedema (see WARNINGS ) .
Lithium: Renal clearance of lithium is reduced by thiazides and increase the risk of lithium toxicity. Increased serum lithium levels and symptoms of lithium toxicity have been reported in patients receiving ACE inhibitors during therapy with lithium. Monitor lithium levels when used concomitantly with Benazepril HCl and Hydrochlorothiazide.
Dual Blockade of the Renin-Angiotensin System (RAS): Dual Blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypertension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. Most patients receiving the combination of two RAS inhibitors do not obtain any additional benefit compared to monotherapy. In general, avoid combined use of RAS inhibitors.
Closely monitor blood pressure, renal function and electrolytes in patients on Benazepril HCl and Hydrochlorothiazide and other agents that affect the RAS. Do not coadminister aliskiren with Benazepril HCl and Hydrochlorothiazide in patients with diabetes. Avoid use of aliskiren with Benazepril HCl and Hydrochlorothiazide in patients with renal impairment (GFR < 60 mL/min).
NSAIDs and Cox-2 selective agents: In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, coadministration of NSAIDs, including selective COX- 2 inhibitors, with ACE inhibitors, including benazepril, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving benazepril and NSAID therapy.
The antihypertensive effect of benazepril and hydrochlorothiazide may be attenuated by NSAIDs. Benazepril Benazepril has been used concomitantly with beta-adrenergic-blocking agents, calcium-blocking agents, cimetidine, diuretics, digoxin, hydralazine, and naproxen without evidence of clinically important adverse interactions. Other ACE inhibitors have had less than additive effects with beta adrenergic blockers, presumably because drugs of both classes lower blood pressure by inhibiting parts of the renin-angiotensin system.
Interaction studies with warfarin and acenocoumarol have failed to identify any clinically important effects of benazepril on the serum concentrations or clinical effects of these anticoagulants. Gold: Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) have been reported rarely in patients on therapy with injectable gold (sodium aurothiomalate) and concomitant ACE inhibitor therapy. Hydrochlorothiazide Ion exchange resins: Stagger the dosage of hydrochlorothiazide and ion exchange resins such that hydrochlorothiazide is administered at least 4 hours before or 4 to 6 hours after the administration of resins.
Single doses of either cholestyramine or colestipol resins bind the hydrochlorothiazide and reduce its absorption from the gastrointestinal tract by up to 85% and 43%, respectively. Digitalis glycosides: Thiazide-induced hypokalemia or hypomagnesemia may predispose the patients to digoxin toxicity Skeletal muscle relaxants: Possible increased responsiveness to muscle relaxants such as curare derivatives. Antidiabetic agents: Dosage adjustment of antidiabetic drug may be required.
Antineoplastic agents (e.g., cyclophosphamide, methotrexate): Concom…
👥 Use in Specific Populations ▾
Use in Specific Populations
🧒 Pediatric Use ▾
Pediatric Use Neonates with a history of in utero exposure to Benazepril HCl and Hydrochlorothiazide: If oliguria or hypotension occurs, direct attention toward support of blood pressure and renal perfusion. Exchange transfusions or dialysis may be required as a means of reversing hypotension and/or substituting for disordered renal function. Benazepril, which crosses the placenta, can theoretically be removed from the neonatal circulation by these means; there are occasional reports of benefit from these maneuvers with another ACE inhibitor, but experience is limited.
Safety and effectiveness in pediatric patients have not been established. Renal Impairment Safety and effectiveness of Benazepril HCl and Hydrochlorothiazide in patients with severe renal impairment (CrCL ≤ 30 mL/min) have not been established. No dose adjustment is required in patients with mild (CrCL 60 to 90 mL/min) or moderate (CrCL 30 to 60 mL/min) renal impairment.
Hepatic Impairment No adjustment of the initial dose is required for patients with mild to moderate hepatic impairment (see CLINICAL PHARMACOLOGY ) . Hydrochlorothiazide Minor alterations of fluid and electrolyte imbalance may precipitate hepatic coma in patients with impaired hepatic function or progressive liver disease.
🧓 Geriatric Use ▾
Geriatric Use Of the total number of patients who received Benazepril HCl and Hydrochlorothiazide in U.S. clinical studies of Benazepril HCl and Hydrochlorothiazide, 19% were 65 or older while about 1.5% were 75 or older. Overall differences in effectiveness or safety were not observed between these patients and younger patients. A limited amount of data suggests that the systemic clearance of hydrochlorothiazide is reduced in both healthy and hypertensive elderly subjects compared to young healthy volunteers.
🆘 Overdosage ▾
OVERDOSAGE No specific information is available on the treatment of overdosage with Benazepril HCl and Hydrochlorothiazide; treatment should be symptomatic and supportive. Therapy with Benazepril HCl and Hydrochlorothiazide should be discontinued, and the patient should be observed. Dehydration, electrolyte imbalance, and hypotension should be treated by established procedures.
Single oral doses of 1 g/kg of benazepril caused reduced activity in mice, and doses of 3 g/kg were associated with significant lethality. Reduction of activity in rats was not seen until they had received doses of 5 g/kg, and doses of 6 g/kg were not lethal. In single-dose studies of hydrochlorothiazide, most rats survived doses up to 2.75 g/kg.
Data from human overdoses of benazepril are scanty, but the most common manifestation of human benazepril overdosage is likely to be hypotension. In human hydrochlorothiazide overdose, the most common signs and symptoms observed have been those of dehydration and electrolyte depletion (hypokalemia, hypochloremia, hyponatremia). If digitalis has also been administered, hypokalemia may accentuate cardiac arrhythmias.
Laboratory determinations of serum levels of benazepril and its metabolites are not widely available, and such determinations have, in any event, no established role in the management of benazepril overdose. No data are available to suggest physiological maneuvers (e.g., maneuvers to change the pH of the urine) that might accelerate elimination of benazepril and its metabolites. Benazeprilat is only slightly dialyzable, but dialysis might be considered in overdosed patients with severely impaired renal function (see WARNINGS ) .
Angiotensin II could presumably serve as a specific antagonist-antidote in the setting of benazepril overdose, but angiotensin II is essentially unavailable outside of scattered research facilities. Because the hypotensive effect of benazepril is achieved through vasodilation and effective hypovolemia, it is reasonable to treat benazepril overdose by infusion of normal saline solution.
🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY Mechanism of Action Benazepril and benazeprilat inhibit angiotensin converting enzyme (ACE) in human subjects and in animals. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex.
Inhibition of ACE results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and to decreased aldosterone secretion. The latter decrease may result in a small increase of serum potassium. Hypertensive patients treated with benazepril alone for up to 52 weeks had elevations of serum potassium of up to 0.2 mEq/L.
Similar patients treated with benazepril and hydrochlorothiazide for up to 24 weeks had no consistent changes in their serum potassium (see PRECAUTIONS ) . Removal of angiotensin II negative feedback on renin secretion leads to increased plasma renin activity. In animal studies, benazepril had no inhibitory effect on the vasopressor response to angiotensin II and did not interfere with the hemodynamic effects of the autonomic neurotransmitters acetylcholine, epinephrine, and norepinephrine.
ACE is identical to kininase, an enzyme that degrades bradykinin. Whether increased levels of bradykinin, a potent vasodepressor peptide, play a role in the therapeutic effects of Benazepril HCl and Hydrochlorothiazide remains to be elucidated. While the mechanism through which benazepril lowers blood pressure is believed to be primarily suppression of the renin-angiotensin-aldosterone system, benazepril has an antihypertensive effect even in patients with low-renin hypertension.
Hydrochlorothiazide is a thiazide diuretic. Thiazides affect the renal tubular mechanisms of electrolyte reabsorption, directly increasing excretion of sodium and chloride in approximately equivalent amounts. Indirectly, the diuretic action of hydrochlorothiazide reduces plasma volume, with consequent increases in plasma renin activity, increases in aldosterone secretion, increases in urinary potassium loss, and decreases in serum potassium.
The renin aldosterone link is mediated by angiotensin, so coadministration of an ACE inhibitor tends to reverse the potassium loss associated with these diuretics. The mechanism of the antihypertensive effect of thiazides is unknown. Pharmacokinetics and Metabolism Following oral administration of Benazepril HCl and Hydrochlorothiazide, peak plasma concentrations of benazepril are reached within 0.5 to 1.0 hour.
As determined by urinary recovery, the extent of absorption is at least 37%. In fasting subjects, the rate and extent of absorption of benazepril and hydrochlorothiazide from Benazepril HCl and Hydrochlorothiazide are not different, respectively, from the rate and extent of absorption of benazepril and hydrochlorothiazide from immediate release monotherapy formulations. The estimated absolute bioavailability of hydrochlorothiazide after oral administration is about 70%.
Peak plasma hydrochlorothiazide concentrations (C max ) are reached within 2 to 5 hours after oral administration. Hydrochlorothiazide binds to albumin (40% to 70%) and distributes into erythrocytes. The absorption of benazepril from Benazepril HCl and Hydrochlorothiazide tablets is not influenced by the presence of food in the gastrointestinal tract.
There is no clinically significant effect of food on the bioavailability of hydrochlorothiazide. Cleavage of the ester group (primarily in the liver) converts benazepril to its active metabolite, benazeprilat. Peak plasma concentrations of benazeprilat are reached 1 to 2 hours after drug intake in the fasting state and 2 to 4 hours after drug intake in the nonfasting state.
The serum protein binding of benazepril is about 96.7% and that of benazeprilat about 95.3%, as measured by equilibrium dialysis; on the basis of in vitro studies, the degree of protein binding should be unaffected by age, hepatic dysfunction, or – over th…
