Treatment began with amlodipine 5 mg daily or valsartan 80 mg daily with titration to 10 mg and mg, respectively. Patients were also eligible to receive hydrochlorothiazide HCTZ The primary endpoint was a composite of cardiac events with stroke as a secondary endpoint. Mean blood pressure was lower at the end of the trial in the amlodipine group by The rates of peripheral edema were higher in the amlodipine group No difference in cardiac endpoint was seen between the two groups; however, the incidence of myocardial infarction a secondary outcome was lower in the amlodipine group, which may have been related to better blood pressure control.
When considering starting an ARB, providers should keep in mind the adverse-effect profiles of this class of medication. In general, all ARBs will have the same potential to cause laboratory changes in potassium and other electrolytes; however, ARBs may be more likely to cause hyperkalemia than ACE inhibitors.
A retrospective, observational cohort study of patients taking ACE inhibitors versus ARBs was conducted in a Veterans Affairs Medical Center looking at approximately 2, patients. The number of patients with hyperkalemia still remained higher even after adjustment for renal function. The mechanism resulting in hyperkalemia may include causes such as decreased aldosterone production or impaired potassium secretion within the kidneys.
With angiotensin II receptor blockers, the activity of aldosterone is reduced and therefore prevents the excretion of potassium from the kidneys. Several chain community pharmacies such as Walmart, CVS, and Walgreens offer discount plans for and day supplies of many generic medications. Currently, valsartan is the most widely prescribed ARB on the market, followed by losartan. ARBs are recommended in varying levels of evidence within the most recent guidelines for the management of hypertension because of various mechanisms including renal protection, lowering of blood pressure, and reducing uric acid.
While the evidence to support the use of ARBs versus other antihypertensives varies, ARBs have consistently shown a benefit for lowering blood pressure and have demonstrated favorable tolerability.
Additionally, the generic availability of ARBs now makes it possible for many of these agents to be included on insurance formularies and to provide a wider selection when starting or adjusting therapy.

Manufacturers are required to test for impurities that may be introduced or developed during their manufacturing processes. We review that information in drug applications, including requests to change the manufacturing process.
We employ organic chemists to review applications and referenced information to look for steps — and manufacturing changes — where these risks could be introduced. However, the review of records depends on manufacturers conducting appropriate tests that are capable of detecting the impurity. Tests are selected based on assessments of what impurities may develop based on the manufacturing process.
In other words, it needs to be recognized that there is a risk of an impurity occurring to know that it should be tested for. Before we undertook this analysis, neither regulators nor industry fully understood how the nitrosamines could form during the manufacturing process. Following is an example of an ARB medication label to help you identify the information on your medication:.
Note the manufacturer may be different from the distributor or labeler of your medication. Learn more about the NDC. Contact your pharmacist to get this information if you cannot find it or if you have questions about your medication being recalled.
If the lot number is on the medication bottle, it is usually imprinted on the label and is normally found next to the expiration date.
ARBs may worsen these imbalances by decreasing sodium retention at the proximal and distal tubules of the kidney, and by decreasing potassium secretion in the collecting duct. Patients with a vascular disease, known as renal artery stenosis RAS , in both kidneys, or patients with a single functional kidney and a diagnosis of RAS, should not take ARBs. ARBs affect blood circulation at the kidneys, which can lower the glomerular filtration rate in patients with severe renal disease.
This can worsen kidney function and lead to kidney failure. Similarly, volume depletion should be corrected in patients before starting therapy with an ARB. All three types of medication work on the renin-angiotensin system and taking them together compounds the risk of renal impairment, hyperkalemia, and hypotension.
Make sure your doctor is aware of all medications you are taking in order to avoid potentially dangerous drug interactions. Stop taking an ARB as soon as you suspect you might be pregnant and contact your doctor immediately. ARBs should be avoided during pregnancy and breastfeeding if possible. All ARB medications carry a black box warning about potential harm or fatality to the fetus when ARBs are used in pregnancy. No, angiotensin II receptor antagonists are not controlled substances.
The following are common side that may occur while taking ARBs. This is not an exhaustive list, as it only covers side effects common to all ARBs. Additional side effects may be common to individual drugs within this class. If you are experiencing worrisome or intolerable side effects, consult a doctor or pharmacist for further information and advice.
ARBs have been known to cause a severe side effect called angioedema. This side effect is believed to be caused by bradykinin, a vasodilating peptide that can cause swelling and inflammation. Many of the drugs in this class are available as generics at a lower cost than their brand-name counterpart. Hypertension is the most likely diagnosis to warrant coverage.
Even if an insurance plan covers your medication, it may be less expensive to use a SingleCare coupon. Skip to main content Search for a topic or drug. Learn more about the types of ARBs and their safety here. By Daniel Cardin, Pharm.
