What is benazepril and hydrochlorothiazide, and how does it work (mechanism of action)?
Lotensin HCT is a combination of two drugs, benazepril and hydrochlorothiazide. Benazepril is an angiotensin converting enzyme (ACE) inhibitor that is used for treating high blood pressure. Other ACE inhibitors include enalapril (Vasotec), quinapril (Accupril), captopril (Capoten), fosinopril (Monopril), ramipril (Altace), moexipril (Univasc) and trandolapril (Mavik). ACE is an enzyme in the body which is important for the formation of angiotensin II. Angiotensin II causes constriction of arteries in the body, thereby elevating blood pressure. ACE inhibitors (for example, benazepril) lower blood pressure by inhibiting the formation of angiotensin II, thus relaxing the arteries. Relaxing the arteries not only lowers blood pressure, but the lower blood pressure also reduces the heart's work and improves the output of blood from the heart in patients with heart failure.
Hydrochlorothiazide (HCTZ) is a diuretic (water pill) used for treating high blood pressure (hypertension) and accumulation of fluid. It works by blocking salt and fluid reabsorption in the kidneys, causing increased output of salt and water in the urine (diuresis). The mechanism of its action in lowering high blood pressure is not well understood.
The combination of benazepril and HCTZ reduces blood pressure better than either drug alone. Lotensin was approved by the FDA in May 1992.
What are the side effects of benazepril and hydrochlorothiazide?
Lotensin HCT has side effects of its individual components. The most common side effects are:
- low blood pressure,
- muscle pain,
- stomach upset,
- sexual dysfunction, and
- decreased or increased potassium blood levels.
In rare instances,liver dysfunction and skin yellowing (jaundice) have been reported with ACE inhibitors. Benazepril should not be taken by people with a known allergy to ACE inhibitors. Swelling of the facial tissues and even the upper airways has been reported with ACE inhibitors on very rare occasions, and can lead to serious breathing difficulties.
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.

What is the dosage for benazepril and hydrochlorothiazide?
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.
Which drugs or supplements interact with benazepril and hydrochlorothiazide?
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.
Nitritoid reactions (symptoms include facial flushing, nausea, vomiting, and hypotension) may occur when injectable gold (sodium aurothiomalate), used in the treatment of rheumatoid arthritis, is combined with ACE inhibitors, including benazepril. Hydrochlorothiazide reduces the elimination of lithium (Lithobid, Eskalith) by the kidneys and can lead to lithium toxicity. Nonsteroidal anti-inflammatory drugs, for example, ibuprofen, may reduce the blood pressure lowering effects of hydrochlorothiazide. Blood sugar levels can be elevated by HCTZ necessitating adjustments in the doses of medications that are used for treating diabetes.
Combining HCTZ with corticosteroids may increase the risk for low levels of blood potassium and other electrolytes. Low blood potassium can increase the toxicity of digoxin (Lanoxin). Cholestyramine (Questran, Questran Light) and colestipol (Colestid) bind to hydrochlorothiazide and reduce its absorption from the gastrointestinal tract by 43% to 85%.
Is benazepril and hydrochlorothiazide safe to take if I'm pregnant or breastfeeding?
Both benazepril and HCTZ are excreted in breast milk and may potentially affect nursing infants.
What else should I know about benazepril and hydrochlorothiazide?
What preparations of benazepril and hydrochlorothiazide are available?
Tablets (mg benazepril/mg HCTZ); 5/6.25, 10/12.5, 20/12.5, and 20/25.
How should I keep benazepril and hydrochlorothiazide stored?
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.

Top benazepril and hydrochlorothiazide Related ArticlesComplete List
ACE inhibitors, or angiotensin (generic name) converting enzyme inhibitors, is a class of drugs that interact with blood enzymes to enlarge or dilate blood vessels and reduce blood pressure. These drugs are used to:
- Control high blood pressure (hypertension)
- Treat of heart failure and ventricular dysfunction
- Prevent and treat of kidney disease in people with diabetes or hypertension.
These drugs also improve the survival rate of people who have survived heart attacks and they prevent early death of people from heart attacks, high blood pressure, and heart failure. Sometimes ACE inhibitors are combined with other drugs for treating a condition. Examples of ACE inhibitors include:
- benazepril (Lotensin)
- captopril (Capoten)
- enalapril (Vasotec)
- fosinopril (Monopril)
- ramipril (Altace)
Examples of the most common side effects of this class of drugs are:
- chest pain,
- and rash.
There are serious side effects of this drug like
- kidney failure,
- severe allergic reactions,
- and liver dysfunction or failure.
ACE inhibitors all are similar in the way they work; however, they differ in how the body eliminates doses of the drug. Drug interactions, dosage, and pregnancy and safety information should be reviewed prior to taking this medication.
Congestive Heart Failure (CHF) OverviewCongestive heart failure (CHF) refers to a condition in which the heart loses the ability to function properly. Heart disease, high blood pressure, diabetes, myocarditis, and cardiomyopathies are just a few potential causes of congestive heart failure. Signs and symptoms of congestive heart failure may include fatigue, breathlessness, palpitations, angina, and edema. Physical examination, patient history, blood tests, and imaging tests are used to diagnose congestive heart failure. Treatment of heart failure consists of lifestyle modification and taking medications to decrease fluid in the body and ease the strain on the heart. The prognosis of a patient with congestive heart failure depends on the stage of the heart failure and the overall condition of the individual.
Diabetes MellitusDiabetes is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Drug InteractionsDrug interactions occur frequently. Get facts about the types of drug interactions, what substances or other things that may interact with drugs such as OTC drug and prescription drugs, vitamins, food(s) (grapefruit), and laboratory tests. Find out how to protect yourself from potential drug interactions.
Drugs: What You Should Know About Your DrugsImportant information about your drugs should be reviewed prior to taking any prescription drug. Side effects, drug interactions, warnings and precauctions, dosage, what the drug is used for, what to do if you miss a dose, how the drug is to be stored, and generic vs. brand names.
Febrile SeizuresFebrile seizures, or convulsions caused by fever, can be frightening in small children or infants. However, in general, febrile seizures are harmless. Febrile seizure is not epilepsy. It is estimated that one in every 25 children will have at least one febrile seizure. It is important to know what to do to help your child if he/she has a febrile seizure. Some of the features of a febrile seizure include:
- losing consciousness,
- moving limbs on both sides of the body,
- lasts 1-2 minutes.
Heart AttackHeart attack happens when a blood clot completely obstructs a coronary artery supplying blood to the heart muscle. A heart attack can cause chest pain, heart failure, and electrical instability of the heart.
Heart Attack and Atherosclerosis Prevention
Heart disease and heart attacks can be prevented by leading a healthy lifestyle with diet, exercise, and stress management. Symptoms of heart attack in men and women include chest discomfort and pain in the shoulder, neck, jaw, stomach, or back. Women experience the same symptoms as men; however, they also may experience:
- Extreme fatigue
- Pain in the upper abdomen
Leading a healthy lifestyle with a heart healthy low-fat diet, and exercise can help prevent heart disease and heart attack.
High Blood Pressure HypertensionHigh blood pressure is defined as a pressure of 140/90 mmHg or higher in the arteries. Genetic factors, high salt intake, and increased arterial stiffness cause high blood pressure. Dizziness, headache, nausea, and shortness of breath are just a few symptoms of high blood pressure. Untreated high blood pressure increases the risk of heart disease, kidney disease, atherosclerosis, eye damage, stroke, and increased risk of aneurysms. High blood pressure can be managed with weight loss, lifestyle changes, and medication.

High Blood Pressure TreatmentHigh blood pressure (hypertension) means high pressure (tension) in the arteries. Treatment for high blood pressure include lifestyle modifications (alcohol, smoking, coffee, salt, diet, exercise), drugs and medications such as ACE inhibitors, angiotensin receptor blockers, beta blockers, diuretics, calcium channel blockers (CCBs), alpha blockers, clonidine, minoxidil, and Exforge.
Hydrochlorothiazide (Microzide, Hydrodiuril, Ezide, and Hydro-Par have been discontinued) is a diuretic drug prescribed to treat
- high blood pressure,
- edema caused by heart failure,
- chronic kidney failure,
- nephrotic syndrome, and
- corticosteroid medications.
Drug interactions, side effects, dosage, and pregnancy and breastfeeding information should be reviewed prior to taking this medication.
Kidney FailureKidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure are:
- multiple myeloma, and
