displayName: DESCRIPTION SECTION
FDA Article Code: 34089-3
Benazepril hydrochloride is a white to off-white crystalline powder, soluble (>100 mg/mL) in water, in ethanol, and in methanol. Its chemical name is 3-[[1-(ethoxy-carbonyl)-3-phenyl-(1S)-propyl]amino]-2,3,4,5-tetrahydro-2-oxo-1H-1-(3S)-benzazepine-1-acetic acid monohydrochloride; its structural formula is
Its empirical formula is C24H28N2O5•HCl and its molecular weight is 460.96
Benazeprilat, the active metabolite of benazepril, is a non-sulfhydryl angiotensin-converting enzyme inhibitor. Benazepril is converted to benazeprilat by hepatic cleavage of the ester group.
Benazepril hydrochloride, USP is supplied as film-coated tablets containing 5 mg, 10 mg, 20 mg, and 40 mg of benazepril hydrochloride for oral administration. The inactive ingredients are carnauba wax, colloidal silicon dioxide, crospovidone, hypromellose, lactose monohydrate, magnesium stearate, microcrystalline cellulose, polydextrose, polyethylene glycol, pregelatinized starch, titanium dioxide, and triacetin. The 10 mg tablet also contains FD&C Red No. 40 aluminum lake. The 20 mg tablet also contains black iron oxide and yellow iron oxide. The 40 mg tablet also contains FD&C Blue No. 2 aluminum lake. Benazepril hydrochloride tablets USP, 5 mg, 10 mg, 20 mg and 40 mg meet USP Dissolution Test 2.
INDICATIONS AND USAGE
displayName: INDICATIONS & USAGE SECTION
FDA Article Code: 34067-9
Benazepril hydrochloride tablets, USP are indicated for the treatment of hypertension. It may be used alone or in combination with thiazide diuretics.
displayName: CONTRAINDICATIONS SECTION
FDA Article Code: 34070-3
Benazepril hydrochloride tablets are contraindicated in patients who are hypersensitive to benazepril or to any other ACE inhibitor.
Benazepril hydrochloride tablets are also contraindicated in patients with a history of angioedema with or without previous ACE inhibitor treatment.
Do not co-administer aliskiren with angiotensin receptor blockers, ACE inhibitors, including benazepril hydrochloride in patients with diabetes.
displayName: ADVERSE REACTIONS SECTION
FDA Article Code: 34084-4
Benazepril hydrochloride tablets have been evaluated for safety in over 6000 patients with hypertension; over 700 of these patients were treated for at least one year. The overall incidence of reported adverse events was comparable in benazepril hydrochloride tablets and placebo patients.
The reported side effects were generally mild and transient, and there was no relation between side effects and age, duration of therapy, or total dosage within the range of 2 to 80 mg. Discontinuation of therapy because of a side effect was required in approximately 5% of U.S. patients treated with benazepril hydrochloride tablets and in 3% of patients treated with placebo.
The most common reasons for discontinuation were headache (0.6%) and cough (0.5%) (see
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 hydrochloride tablets are shown below.
Patients in U.S. Placebo-Controlled Studies
Other adverse experiences reported in controlled clinical trials (in less than 1% of benazepril patients or with less than 1% difference in incidence between benazepril or placebo treatment), and rarer events seen in post-marketing experience, include the following (in some, a causal relationship to drug use is uncertain):

displayName: OVERDOSAGE SECTION
FDA Article Code: 34088-5
Single oral doses of 3 g/kg benazepril were associated with significant lethality in mice. Rats, however, tolerated single oral doses of up to 6 g/kg. Reduced activity was seen at 1 g/kg in mice and at 5 g/kg in rats. Human overdoses of benazepril have not been reported, but the most common manifestation of human benazepril overdosage is likely to be hypotension, which can be associated with electrolyte disturbances and renal failure.
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. Benazepril is only slightly dialyzable, but dialysis might be considered in overdosed patients with severely impaired renal function (see
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.
If ingestion is recent, activated charcoal should be considered. Gastric decontamination (e.g., vomiting, gastric lavage) may be considered in individual cases, in the early period after ingestion.
Patients should be closely monitored for blood pressure and clinical symptoms. Supportive management should be employed to ensure adequate hydration and to maintain systemic blood pressure.
In the case of marked hypotension, physiological saline solution should be administered intravenously; depending on the clinical situation the use of vasopressors (e.g., catecholamines i.v.) may be considered.
