A multiple dose pharmacokinetic study was conducted in 40 hypertensive male and female pediatric patients aged 2 months to ≤ 16 years following daily oral administration of 0.07 to 0.14 mg/kg Nacor maleate. At steady state, the mean effective half-life for accumulation of Nacorat was 14 hours, and the mean urinary recovery of total Nacor and Nacorat in 24 hours was 68% of the administered dose. Conversion of Nacor to Nacorat was in the range of 63-76%. The overall results of this study indicate that the pharmacokinetics of Nacor in hypertensive children aged 2 months to ≤ 16 years are consistent across the studied age groups and consistent with pharmacokinetic historic data in healthy adults.

In a clinical study involving 110 hypertensive pediatric patients 6 to 16 years of age, patients who weighed

Before taking this medicine

You should not use Nacor if you are allergic to it, or if you have:

Do not take Nacor within 36 hours before or after taking medicine that contains sacubatril (such as Entresto).

If you have diabetes, do not use Nacor together with any medication that contains aliskiren (Amturnide, Tekturna, Tekamlo).

You may also need to avoid taking Nacor with aliskiren if you have kidney disease.

To make sure Nacor is safe for you, tell your doctor if you have:

kidney disease (or if you are on dialysis);

a history of blood clot or stroke (including TIA or "mini-stroke");

an electrolyte imbalance (such as high levels of potassium in your blood); or

Do not use if you are pregnant. If you become pregnant, stop taking this medicine and tell your doctor right away. Nacor can cause injury or death to the unborn baby if you take the medicine during your second or third trimester.

Nacor can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using this medicine.

Q: About two weeks ago, while undergoing tests for allergies, I had an allergic reaction; swelling in my lips. I usually take Nacor 20 mg. It didn't seem to work to help lower my blood pressure, which rose to 183/121. Since then I've been careful to avoid anything with any type of nuts since the reaction was caused by almonds. However, yesterday, under my lower lip, I noticed a funny feeling and I eventually looked in the mirror. I saw redness and one small spot of swelling on the skin. I was baffled as to what could have caused it. I later remember it hadn't been long since I'd taken a dose of Nacor. Could this be angioedema? I have never had problems like this with Nacor and I've been taking it for at least five years. I do feel I have plateaued on it. I've been taking the maximum dose for more than a year and it doesn't seem to have the same effects as before. I can only take ACE inhibitors and ARBs to lower my blood pressure because of other medical conditions, including CHF. Should I switch to another ACE inhibitor? My blood pressure is around 140/90 when I take Nacor only, and I was supposed to have a second medication, but which one should I take? I've had trouble with some of the others including clonidine, nifedipine, Norvasc, metoprolol and propanolol, and they all had to be stopped.

A: Angioedema is an uncommon side effect associated with Nacor and usually occurs in the first month of treatment. Although it is possible to experience this condition later during treatment, it is more common in African American patients, women, and people who have a history of drug or seasonal allergies. The exact prevalence and incidence of ARB-induced angioedema are not known, but it is thought to be significantly lower than the ACE inhibitors. For patients who cannot take any other alternatives, ARBs seem to be the way to go for people who have had this issue with ACE inhibitors, although careful monitoring is recommended for the physician. There are no clear cut ways to distinguish which medication would be best in this case for your condition, but it has been shown that losartan (Cozaar) seems to show the most cases with angioedema, if it happens at all, with the ARBs.
