Benazepril may reduce kidney function in some patients and should not be used by patients who have bilateral renal artery stenosis (narrowing of both arteries supplying the kidneys). Rare cases of rhabdomyolysis (muscle breakdown), reduced number of platelets, and pancreatitis have been reported. Hydrochlorothiazide may increase blood glucose levels.
GENERIC AVAILABLE: Yes
PREPARATIONS: Tablets (mg benazepril/mg HCTZ); 5/6.25, 10/12.5, 20/12.5, and 20/25.
STORAGE: Lotensin HCT should be stored at 59 F to 86 F (15 C to 30 C) and be protected from excessive light and humidity. It should be kept in a tight, light-resistant container.
DOSING: The dose of Lotensin HCT is tailored to the patient's needs. The recommended dose when switching from benazepril or hydrochlorothiazide to Lotensin HCT is 10 mg/12.5 mg once daily. Dosage may be increased every 2 to 3 weeks, and the maximum dose is 20 mg /25 mg.
DRUG INTERACTIONS: Combining benazepril with potassium supplements, potassium containing salt substitutes, and potassium conserving diuretics such as amiloride (Moduretic), spironolactone (Aldactone), and triamterene (Dyazide, Maxzide), can lead to dangerously high blood levels of potassium.
Combining benazepril or other ACE inhibitors with nonsteroidal anti-inflammatory drugs (NSAIDs) in patients who are elderly, fluid-depleted (including those on diuretic therapy), or with poor kidney function may result in reduced kidney function, including kidney failure. These effects usually are reversible.
There have been reports that aspirin and other NSAIDs such as ibuprofen (Advil, Children's Advil/Motrin, Medipren, Motrin, Nuprin, PediaCare Fever, and many others), indomethacin (Indocin, Indocin-SR), and naproxen (Anaprox, Naprelan, Naprosyn, Aleve) may reduce the effects of ACE inhibitors.
