Summary
Amlodipine and Benazepril are primarily used to treat high blood pressure, also known as hypertension. By controlling blood pressure, they help prevent serious complications such as heart disease, heart attacks, strokes, and kidney failure.
Amlodipine, a calcium channel blocker, relaxes blood vessels making it easier for the heart to pump blood. Benazepril, an ACE inhibitor, reduces certain chemicals that tighten blood vessels, allowing blood to flow more smoothly. Together, they effectively lower blood pressure.
The usual adult daily dose starts at 2.5 mg of Amlodipine and 10 mg of Benazepril taken orally once a day. The dose can be adjusted based on the patient's response, with a maximum dose of 10 mg of Amlodipine and 40 mg of Benazepril per day.
Common side effects include cough, headache, dizziness, and swelling of the hands, feet, ankles, or lower legs. Serious adverse effects can include swelling of the face, throat, tongue, lips, or eyes, difficulty swallowing or breathing, fainting, severe skin rash, and yellowing of the skin or eyes.
Amlodipine and Benazepril should not be used during pregnancy due to the risk of fetal harm. Patients with a history of angioedema, or those allergic to ACE inhibitors or calcium channel blockers should avoid this medication. It's contraindicated with aliskiren in diabetic patients. Caution is advised in patients with kidney or liver problems and those undergoing surgery.
Indications and Purpose
What is combination of Amlodipine and Benazepril used for?
Amlodipine and benazepril are primarily indicated for the treatment of high blood pressure (hypertension). By lowering blood pressure, they help prevent complications such as heart disease, heart attacks, strokes, and kidney failure. Amlodipine relaxes blood vessels, while benazepril reduces chemicals that tighten blood vessels, both contributing to improved blood flow and reduced blood pressure.
How does combination of Amlodipine and Benazepril work?
Amlodipine and benazepril work together to lower blood pressure. Amlodipine, a calcium channel blocker, relaxes blood vessels by inhibiting the influx of calcium ions into vascular smooth muscle and cardiac muscle, reducing the heart's workload. Benazepril, an ACE inhibitor, decreases the production of angiotensin II, a chemical that causes blood vessels to tighten, thus allowing blood to flow more easily. Together, they effectively reduce blood pressure and improve blood flow.
How effective is combination of Amlodipine and Benazepril?
Clinical trials have demonstrated that the combination of amlodipine and benazepril effectively lowers blood pressure in patients not adequately controlled on monotherapy. Amlodipine, as a calcium channel blocker, and benazepril, as an ACE inhibitor, work synergistically to enhance antihypertensive effects. Studies show that the combination therapy provides a greater reduction in blood pressure compared to either drug alone, particularly in nonblack patients, and helps reduce amlodipine-induced edema.
How does one know if combination of Amlodipine and Benazepril is working?
The benefit of amlodipine and benazepril is primarily assessed by monitoring blood pressure levels. Regular check-ups with a healthcare provider are essential to ensure the medication is effectively lowering blood pressure to the desired range. Additionally, the doctor may order lab tests to monitor the body's response to the medication, ensuring that it is working effectively without causing adverse effects.
Directions for Use
What is the usual dose of combination of Amlodipine and Benazepril?
The usual adult daily dose for the combination of amlodipine and benazepril starts at 2.5 mg of amlodipine and 10 mg of benazepril, taken orally once a day. The dose can be adjusted based on the patient's response, with a maximum dose of 10 mg of amlodipine and 40 mg of benazepril per day. Amlodipine helps by relaxing blood vessels, while benazepril reduces chemicals that tighten blood vessels, both contributing to lowering blood pressure.
How does one take combination of Amlodipine and Benazepril?
Amlodipine and benazepril should be taken once daily, at the same time each day, with or without food. Patients are advised to follow any dietary instructions provided by their doctor, such as a low-salt or low-sodium diet, to enhance the medication's effectiveness. It's important to avoid using salt substitutes containing potassium without consulting a healthcare provider, as this can affect potassium levels in the body.
For how long is combination of Amlodipine and Benazepril taken?
Amlodipine and benazepril are typically used as a long-term treatment for high blood pressure. While they help control blood pressure, they do not cure it, so patients are usually advised to continue taking the medication even if they feel well. The duration of use is often indefinite, as maintaining controlled blood pressure is crucial for preventing complications such as heart disease and stroke.
How long does it take for combination of Amlodipine and Benazepril to work?
Amlodipine and benazepril combination medicine typically starts working within 2 weeks to achieve its full antihypertensive effect. Amlodipine, a calcium channel blocker, works by relaxing blood vessels, which helps to lower blood pressure. Benazepril, an ACE inhibitor, decreases certain chemicals that tighten blood vessels, allowing blood to flow more smoothly. Both medicines work together to effectively reduce blood pressure, but the full effect may take a couple of weeks to be noticeable.
How does one store combination of Amlodipine and Benazepril?
Amlodipine and benazepril do not require refrigeration. They should be stored at room temperature, between 20° to 25°C (68° to 77°F), and kept in a tightly closed container away from excess heat and moisture. It's important to keep the medication out of reach of children and to dispose of any unneeded medication through a take-back program rather than flushing it down the toilet.
Warnings and Precautions
Are there harms and risks from taking combination of Amlodipine and Benazepril?
Common side effects of amlodipine and benazepril include cough, headache, dizziness, and swelling of the hands, feet, ankles, or lower legs. Serious adverse effects can include swelling of the face, throat, tongue, lips, or eyes, difficulty swallowing or breathing, fainting, severe skin rash, and yellowing of the skin or eyes. These side effects may require immediate medical attention. The combination of these medications can also lead to more frequent or severe chest pain in some individuals.
Can I take combination of Amlodipine and Benazepril with other prescription drugs?
Significant drug interactions with amlodipine and benazepril include those with aliskiren, especially in patients with diabetes, as it can increase the risk of kidney problems, low blood pressure, and high potassium levels. Caution is also advised when used with lithium, as it can increase lithium levels and toxicity. Additionally, coadministration with simvastatin should be limited to 20 mg daily due to increased risk of side effects. Patients should inform their healthcare provider of all medications they are taking to avoid adverse interactions.
Can I take combination of Amlodipine and Benazepril with vitamins or supplements?
Patients taking amlodipine and benazepril should be cautious with potassium supplements and potassium-containing salt substitutes, as these can increase the risk of hyperkalemia (high potassium levels in the blood). It's important to inform healthcare providers about all vitamins and supplements being taken to avoid potential interactions. Regular monitoring of potassium levels may be necessary to prevent complications.
Can I take combination of Amlodipine and Benazepril if I am pregnant?
Amlodipine and benazepril are not safe for use during pregnancy, especially in the second and third trimesters, due to the risk of fetal harm.
