Amlodipine (Oral)

Amlodipine (oral route) is used to treat high blood pressure.

Overview

  • Brand Name: Norvasc

Amlodipine is a high-demand medication that, when combined with other drugs, treats high blood pressure, also called hypertension. When you have hypertension, your arteries and heart must work harder. Over time, this can cause the arteries and heart to malfunction. There is a ripple effect of damage from hypertension that can impact the heart, brain and kidneys and cause heart failure, stroke or kidney failure. To reduce the risks of high blood pressure, Amlodipine works to lower your blood pressure to protect your organs.

Amlodipine does this by acting as a calcium channel blocker (CCB). It impacts how calcium moves into the cells that make up your heart and blood vessels. By doing so, the drug allows the blood vessels to relax, which lowers your blood pressure. When your blood pressure is lower, the blood supplies more blood and oxygen to your heart.

Amlodipine is used with another kind of drug, called an angiotensin-converting enzyme, or ACE inhibitor. With the help of this drug, your body can ignore a substance that makes blood vessels constrict. Lower blood pressure doesn't strain the heart or arteries.

You can only get amlodipine with a prescription from your doctor. In addition, a treatment regimen for hypertension may require other changes. For instance, weight control is a key factor for some people who get their blood pressure under control. Dietary factors that help ensure this medicine has the optimal effect include reducing the amount of sodium you consume. However, check with your doctor prior to making life and diet changes.

It is important to understand that this medicine only helps control high blood pressure and does not act as a cure for the disease. As long as the real causes remain unresolved, you are dependent on your medication to keep the condition under control.

Therefore, continue to take the medication, even if you feel better. Take steps to lower your blood pressure, then keep it down. Once they get on hypertension medications, many take it for as long as they live to combat heart failure, strokes, blood vessel disease and kidney disease.

Take Amlodipine with or without food, although some people may be prone to nausea if they take it on an empty stomach. For optimal results, set a time and take your medicine at the same times.

NORVASC has undergone strict testing and proven safe in 11,000 patients in U.S. and abroad during clinical trials. NORVASC was well-tolerated in patients who received a dosage of up to 10 mg daily. Most negative results during therapy mild and not life-threatening. In controlled trials that compared NORVASC (up to 10 mg) to placebo therapy, the trial was stopped for individuals due to side effects in 1.5% of those receiving NORVASC. This compares favorably against the 1% patients taking the placebo and reporting similar side effects.

Dosage

This product is available in the following dosage forms:

  • Tablet
  • Tablet, Disintegrating

You can expect to have a customized dosage based on your level of hypertension and other factors. Your doctor may request additional directions be printed on the prescription label.

Follow your doctor's verbal or written instructions as well as directions on the pharmacy label. Below, there is a sample of average doses of this medicine. If your prescription is higher or lower, feel free to discuss the reasons with a healthcare specialist. Don't risk your health by changing the dosage without your doctor's express directions to do so.

As a reminder, there are different forms of this medicine that can impact the amounts of the dosages. Your doctor may decide, for example, to have you take fewer or more doses of lower strength for your hypertension.

For adult high blood pressure:

Your doctor will most likely start you out on one capsule that has 2.5 milligrams amlodipine daily. This is called the initial dose. Depending on whether this reduces your high blood pressure sufficiently, the doctor might adjust that up or down. Here is one potential scenario.

  • Initial dose of 2.5 mg Amlodipine orally once a daily
    Maintenance dosage ranges: Amlodipine at 2.5 to 10 mg accompanied by an ACE inhibitor at 10 to 40 mg orally once daily

If your hypertension persists, your doctor can increase the dose and split the dosage as follows.

  • Maximum dose: Amlodipine: 10 mg a day half in the morning and half at night, for example)

Missed Dose

When you forget a dose, take it as soon as you remember, but don't double up on your regular dosage to catch up. Also, if it's been longer than 12 hours since your last dose, skip it and wait for the next dose. Take it at the usual time and be as consistent as possible

Additional Comments:

Your doctor will usually wait at least two weeks before suggesting any changes. This gives your body a chance to adapt to the dosage. He may increase or decrease the strength, depending on how your body reacts. Once you reach the target blood pressure goal, you will likely be prescribed that dosage if it continues to control your blood pressure levels.

Amlodipine may not provide the reductions expected in African-Americans.

Overdose

If you think you may have overdosed and are having trouble breathing, have someone call 911 right away. Look for the following symptoms: fainting, very fast or slow pulse, dizziness.

Prescriptions of amlodipine are specific to the individual they were prescribed for. Sharing medication with others puts their health at risk.

Interactions

When taking these medications for high blood pressure, make sure your doctor is aware of all the medicines and supplement you are using together. This is especially true in the case of certain drugs that can interact with your amlodipine. The following medicines are listed due to their individual risks, they are not inclusive of all such interactions with all drugs.

Warnings

When you decide to use any medication, the risks of using it are compared to those of not using it. Unfortunately, as in the case of these medications, you are taking your life in your own hands This decision should include discussion with you doctor on the following topics:

Allergies

If you have or develop allergic symptoms after taking these mediations, tell your health care professional. If you have any known or suspected allergies to medicines, tell your doctor. Let him know of any allergies you have related to dyes, preservatives, animals or foods. Read the medication package labels carefully.

Pediatric

There is a gap in the knowledge base, when it comes to studies performed in the pediatric age group, to determine the efficacy of amlodipine. The safety of using them to treat children with high blood pressure hasn't been established.

Geriatric

In regard to the elderly, not enough studies have been performed to suitably determine if there are any problems specific to this age group that would impact the dependability of prescribing these drugs to geriatric patients. When elderly patients have liver and kidney conditions, extra care should be taken as a precautionary measure, including a downward adjustment of their dosage and the frequency in taking the medications.

Pregnancy

There is a risk to the fetus in all trimesters, according to available studies. The benefit of these drugs in a life-threatening event could outweigh this risk.

Breastfeeding

Amlodipine

There isn't enough information to determine the risk to the baby if the mother is taking amlodipine while breastfeeding. So, that leaves it up to the mother and her doctor to weigh the risks and make a decision.

Benazepril

Studies indicate a minimal risk associated with using this drug while breastfeeding. Ask your doctor to provide her opinion based on your health and the proposed risk to your baby.

Other Considerations

If you have other medical problems that could exacerbate your hypertension, the efficacy of these medicines may be reduced. Inform your doctor of any of the following conditions:

  • Kidney disease. Risk of increasing potassium levels.
  • Fluid imbalances. Causes dehydration, diarrhea and vomiting
  • Electrolyte imbalance. Risk of low sodium levels
  • Liver disease. Can make this condition worsen.

Heart Related

The following heart conditions can impact the effects of these drugs.

  • Severe, chronic heart disease
  • Angina, which is severe chest pain
  • Aortic stenosis, which is heart valve problems

Congestive heart failure can lead to kidney problems or cause side effects related to heart failure to worsen. If you have experience angioedema (swollen face, tongue, arms, or legs) with other medicines, that increases the likelihood of experiencing it again.

Diabetes

Diabetic patients taking aliskiren (Tekturna®) shouldn't use this medicine. There are several other considerations if you have diabetes. including

  • Have your doctor check your progress regularly to ensure this medicine is having the desired impact. This could require blood tests to check for side effects.
  • Use birth control while on these drugs to prevent unwanted impacts on the fetus.
  • If you have diabetes there is a greater risk of experiencing heightened allergic reactions, including anaphylaxis. Anaphylaxis threatens your life, especially if you don't receive immediate medical care.
  • Call your doctor immediately if you notice continuous itchiness, rashes, difficulty breathing or swallowing or swelling in your extremities, or tongue, lips or face.
  • Call a health care professional if severe stomach pain occurs. Let them know whether you have vomited or may need to. This could be a symptom of intestinal angioedema.
  • While taking this medicine, you can have angina, or chest pain.
  • Heart attacks can occur if you suffer from advanced heart or blood vessel disease. Here are some symptoms indicating a heart attack: chest pain or discomfort, irregular heartbeat, pain in your jaw, back, arms or neck.
  • If you have diabetes, pay attention to dizziness and fainting spells, especially if you are standing up or getting up after lying down. This can happen after taking a diuretic (water pill).
  • Avoid driving immediately after taking these medications until you can determine how your body reacts.
  • If you experience a feeling of faintness, call your doctor immediately. Sit down or lie down to avoid falling.
