Association of Angiotensin-Converting Enzyme Inhibitor or Angiotensin Receptor Blocker Use With COVID-19 Diagnosis and Mortality Cardiology JAMA

ARB definition and meaning

Patients with COVID-19 from February 22 to May 4, 2020, were identified using ICD-10 codes and followed up from day of diagnosis to outcome or end of study period . For the susceptibility analysis, a nested case-control framework was used. A cohort of all patients with hypertension in Denmark was followed up between February 1, 2020, and until incident COVID-19 diagnosis, death without incident COVID-19 diagnosis, or May 4, 2020, whichever came first. Patients with COVID-19 and prior hypertension were designated as cases in the analysis, and these were matched with 10 controls on age and sex among users of antihypertensive drugs without COVID-19.

  • I continue ACE inhibitors in patients who are already taking them without adverse effects, and I change to ARBs in patients who later become unable to tolerate ACE inhibitors.
  • Increased salt in the body and tightened blood vessels may cause our blood pressure to rise.
  • Therefore, they are often substituted for ACE inhibitors when patients complain of cough with ACE inhibitors.
  • This was done in a subgroup of patients using either CCBs or ACEI/ARBs; patients who used both ACEI/ARBs and CCBs were not included.
  • Learn how they work, their benefits, and their side effects.
  • In most cases, they are exempt from federal, state and local taxes.

In my medical practice, I try to make sure patients with HFrEF, hypertension, chronic kidney disease, and coronary artery disease with left ventricular dysfunction receive an inhibitor of the renin-angiotensin-aldosterone system. ARBs are used for controlling high blood pressure, treating heart failure, and preventing kidney failure in people with diabetes or high blood pressure. In 2018 and in 2019, the U.S Food and Drug Administration found traces of NDMA and NDEA impurities in the angiotensin II receptor blocker drug products valsartan, losartan, and irbesartan. A review of clinical studies on angiotensin II receptor blockers and risk of cancer. Table 4 shows the characteristics of the cohort of patients with hypertension at the start of follow-up .

Meaning of arb in English

The comparative efficacy and safety of the angiotensin receptor blockers in the management of hypertension and other cardiovascular diseases. The angiotensin II receptor blockers have differing potencies in relation to blood pressure control, with statistically differing effects at the maximal doses. When used in clinical practice, the particular agent used may vary based on the degree of response required. ARBs are typically used to treat high blood pressure, heart failure, and chronic kidney disease.

ARB definition and meaning

Some ACE-Inhibitors are prodrugs, which means the compound is inactive until metabolized in the liver into the active substance allowing for increased absorption from the GI tract and prevention of ARB definition and meaning the first-pass effect. Nevertheless, the much debated differences in outcomes between ACE inhibitors and ARBs do not seem to be real and may have originated from a generational gap in the trials.

Are there any differences among the different types of ARBs?

ACE inhibitors block the production of angiotensin II, a substance that narrows blood vessels and releases hormones such as aldosterone and norepinephrine, by inhibiting an enzyme called angiotensin converting enzyme. Angiotensin II, aldosterone, and norepinephrine all increase blood pressure and urine production by the kidneys. If levels of these three substances decrease in the body, this allows blood vessels to relax and dilate , reducing both blood and kidney pressure.

ARB definition and meaning

Patients with other indications for ACEI/ARB therapy were excluded to limit confounding by indication. This led to research into inhibiting the renin-angiotensin system at its first step and a new type of medicine the direct renin inhibitors . Renin inhibitors represent an alternative strategy for inhibiting the renin-angiotensin system. They have a mechanism of action different from that of ACE inhibitors and angiotensin receptor antagonists. Whether renin inhibitors offer therapeutic benefits beyond those provided by ACE inhibitor and angiotensin receptor antagonist therapies will require their direct comparison in clinical outcome studies. One of the criticisms Marciniak made was that the earlier FDA meta-analysis did not count lung carcinomas as cancers. In ten of the eleven studies he examined, Marciniak said that there were more lung cancer cases in the ARB group than the control group.


Users of ACEI/ARBs were of similar age as the overall group of patients with hypertension; the median age was 71 years (IQR, 62-78) for ACEI/ARB users and 71 years (IQR, 62-78) for the entire cohort, whereas CCB users were older (median age, 73 years [IQR, 65-80]). Prevalence of prior diabetes and myocardial infarction were also similar for ACEI/ARB users (12.5% and 12.7%) compared with the entire hypertension cohort (12.1% and 13.5%); more CCB users had prior myocardial infarction (16.9%) but fewer had diabetes (8.0%).

Since ARBs may increase blood levels of potassium, the use of potassium supplements, salt substitutes , or other drugs that increase potassium may result in excessive blood potassium levels and cardiac arrhythmias. In November 2020, the Committee for Medicinal Products for Human Use of the EMA aligned recommendations for limiting nitrosamine impurities in sartan medicines with recommendations it issued for other classes of medicines. The main change concerns the limits for nitrosamines, which previously applied to the active ingredients but now apply instead to the finished products (e.g. tablets). These limits, based on internationally agreed standards (ICH M7), should ensure that the excess risk of cancer from nitrosamines in any sartan medicines is below 1 in 100,000 for a person taking the medicine for lifelong treatment. Indeed, as a consequence of AT1 blockade, ARBs increase angiotensin II levels several-fold above baseline by uncoupling a negative-feedback loop.

For what conditions are ARBs used?

To increase the robustness of the exposure definition and results, all analyses were repeated among ACEI/ARB users who filled a prescription within 3 months of the index date instead of 6 months. In addition, analyses were performed for those who filled more than 1 prescription within 6 months of the index date. Many investors invested in auction rate bonds due to their high investment grade rating, their tax-exempt status, and their cash-equivalent status. In most cases, they are exempt from federal, state and local taxes. The ARB has a slightly higher after-tax yield than a money market and certificate of deposits because of their increased risk and complex nature.

Going back a lot further, many such arbs sustained big losses in the so-called crash of ’87. Improve your vocabulary with English Vocabulary in Use from Cambridge. Half the shares may have come from arbs and the rest from holders who wanted a quick exit. Needs to review the security of your connection before proceeding. Robert Rubin, who later became President Clinton’s secretary of the Treasury, got his start in risk arb under Levy and later ran the equities desk.

Researchers say short sessions of daily breathing exercises can help lower blood pressure. Bear in mind that your body may respond differently than other people’s to any medication. If you have side effects from your medication, tell your doctor immediately. Talk with them, weigh your options, and then decide on the best treatment plan for you. Pain relievers such as ibuprofen and naproxen may also interact with ARBs to affect your potassium levels. Some people may experience a chronic cough when they take ACE inhibitors, but ARBs don’t usually have this side effect. This is one of the reasons ARBs are often used instead of ACE inhibitors.

  • ACE-Inhibitors and ARB’s are not recommended for patients who are pregnant, or have a history of angioneurotic edema, hyperkalemia, or bilateral renal artery stenosis.
  • An auction rate security is a variable-rate security sold to investors through a Dutch auction at the lowest interest rate possible.
  • Blockage of AT1 receptors directly causes vasodilation, reduces secretion of vasopressin, and reduces production and secretion of aldosterone, among other actions.
  • Groups shown in eTable 2 in the Supplement are not exclusive, but for outcomes analyses, patients represented in both groups were excluded.
  • Losartan may be best suited for heart failure, kidney damage related to diabetes, and stroke prevention.

Fluconazole impairs the conversion of losartan to its active form, and rifamycin reduces blood levels of losartan . Some ARBs are slightly better at reducing blood pressure than others; in some studies, irbesartan and candesartan were slightly more effective in reducing blood pressure than losartan . However, specific ARBs may be recommended for other medical conditions, according to the American Journal of Cardiovascular Drugs. According to the Centers for Disease Control and Prevention , high blood pressure affects 1 in 3 American adults. Only 54 percent of people with the condition have it under control.
