[5] In 2017, it was the ninth most commonly prescribed medication in the United States, with more than 51 million prescriptions. Of the dihydropyridines, nifedipine has been extensively studied; however, in the same category, felodipine, amlodipine, and isradipine seem to be equally effective. Renin is released from the kidneys when there is reduced renal arterial pressure, sympathetic activation, or increased sodium delivery to the distal renal tubule. A 39-year-old member asked: is prescription losartan potassium a beta blocker? Paul S. Mueller, MD, MPH, FACP reviewing Choi HK et al. Answered by Dr. Calvin Weisberger: Losartan: Losartan is not a beta blocker. In this population, Losartan potassium tablet reduces the rate o… In addition, the associations were stronger with both a longer duration and a higher dose of use, report Hyon Choi (Boston University School of Medicine, Massachusetts, USA) and team in the British Medical Journal. [9] Adverse outcomes do not differ by sex, age or race. This trial aims to compare the efficacy of combination of calcium channel blocker (CCB) or thiazide diuretic with an angiotensin receptor blocker (ARB). Peak plasma concentrations of losartan and EXP3174 occur about one hour and three to four hours, respectively, after an oral dose. The calcium channel blockers that have been approved for use in the US include: amlodipine (Norvasc) amlodipine and atorvastatin (Caduet) amlodipine and benazepril (Lotrel) amlodipine and valsartan (Exforge) Losartan potassium tablets are indicated for the treatment of diabetic nephropathy with an elevated serum creatinine and proteinuria (urinary albumin to creatinine ratio ≥300 mg/g) in patients with type 2 diabetes and a history of hypertension. [34], Losartan is a uricosuric. Calcium channel blockers. It works by blocking angiotensin II. They relax and widen the blood vessels by inhibiting the action of calcium, which plays a major role in activating muscles. For the study, Choi and team analysed data on a cohort of 24,768 people aged 20-79 years with newly diagnosed gout, and a random sample of 50,000 matched control individuals, taken from the UK general practice health improvement network database. If the decrease in eGFR or the increase in serum creatinine persists despite these measures: Stop the ARB or Calcium channel blockers are available in short-acting and long-acting forms. Reduction in blood pressure occurs independently of the status of the renin–angiotensin system. [9], In October 2014, the U.S. Food and Drug Administration (FDA) issued a black box warning that losartan can cause fetal toxicity, and should be discontinued as soon as pregnancy is detected. The study found that patients with hypertension currently using CCBs had a 13% lower risk for gout relative to those who never used CCBs, while those currently using losartan had a 19% lower risk relative to never-users. [9] Losartan should not be taken by people who are diabetic and taking aliskiren. [6][8], Losartan is used for hypertension, including in people with left ventricular hypertrophy (enlarged heart muscle), and kidney dysfunction among type II diabetics. This relaxation causes the blood pressure to drop. [12], The most common adverse effects for losartan in adults are upper respiratory infections, dizziness, and back pain. Based on the 2013 American College of Cardiology Foundation/American Heart Association (ACCF/AHA) guideline for the management of heart failure, losartan is one of 3 effective and recommended angiotensin II receptor blockers (ARBs) (ie, candesartan, losartan, valsartan) in patients with heart failure with reduced ejection fraction who cannot tolerate angiotensin-converting enzyme … Both losartan and EXP3174 are more than 98% bound to plasma proteins. [36] Because losartan can cause hyperkalemia, individuals should not use potassium supplements or salt substitutes containing potassium without appropriate monitoring by a physician. [6][7] A version combined with hydrochlorothiazide is available[2] and, in 2017, it was the 67th most commonly prescribed medication in the United States, with more than eleven million prescriptions. "Our findings suggest that calcium channel blockers and losartan may be protective against the risk of gout among people with hypertension," conclude the researchers. [11] One study demonstrated losartan was superior to atenolol in the primary prevention of adverse cardiovascular events (myocardial infarction or stroke), with a reduction in cardiovascular morbidity and mortality for a comparable reduction in blood pressure. About losartan. All of the physiological effects of angiotensin II, including release of aldosterone, are antagonized in the presence of losartan. [13] As with other angiotensin receptor blockers, losartan may injure the liver, although this effect appears to be rare. Following a 2-week placebo run-in, 440 adults (45-80 years old) were randomized to receive either amlodipine 5 mg once daily or losartan 50 mg once daily. [2] Severe adverse effects may include angioedema, low blood pressure, and kidney problems. Losartan blocks the action of angiotensin II, resulting in the relaxation of the blood vessels. Diuretics, also known as water pills, are medications that act on the kidneys to increase … Short-acting medications work quickly, but their effects last only a few hours. BMJ 2012 Jan 12. © 2020 Springer Healthcare is part of the Springer Nature Group, Cardiology | Calcium channel blockers, losartan best for patients at risk for gout | medwirenews.com. [39], Losartan is generally marketed as the (basic) potassium salt of the aromatized negatively charged tetrazole, called "losartan potassium". [34] Renin then acts by converting angiotensinogen to angiotensin I; angiotensin converting enzyme (ACE) converts angiotensin I to angiotensin II; angiotensin II causes vasoconstriction and aldosterone release. Cozaar (losartan) Diovan (valsartan) Avapro (irbesartan) Calcium Channel Blockers . A calcium channel blocker used to treat hypertension and angina. As a result of losartan dosing, plasma renin activity increases due to removal of the angiotensin II feedback. Cardizem (diltiazem), Plendil (felodipine) and Norvasc (amlodipine) and other calcium channel blockers work by providing more oxygen to the heart, helping it to pump more effectively. The combination was patented by Novartis Pharmaceuticals and sold under the brand name Exforge. These medications are used in adults and children over the age of six to lower mild-to-moderate hypertension (high blood pressure).Angiotensin II is a chemical that the body releases to cause the constriction of blood vessels.
