ORLANDO — A 150-mg/day dosage of losartan was better for preventing events in heart failure patients than was the conventional, 50-mg/day dosage in a randomized comparison involving nearly 4,000 patients followed for more than 4 years. Dosage . Maintenance dose: 25 to 100 mg orally in 1 to 2 divided doses. In light of these data, The Heart failure Endpoint evaluation of Angiotensin II Antagonist Losartan (HEAAL) study was developed to determine whether losartan 150 mg is superior to losartan 50 mg (antihypertensive dose) in reducing morbidity and mortality among patients with symptomatic heart failure who are intolerant of angiotensin-converting enzyme (ACE)-inhibitors. Table 1. Maintenance dose: 25 to 100 mg orally in 1 to 2 divided doses. In the present study the authors asked whether losartan use is associated with increased all-cause mortality in heart failure (HF) patients compared with candesartan. Chronic heart failure when ACE inhibitors are unsuitable or contra-indicated use prohibited. Losartan is used alone or together with other medicines to treat high blood pressure (hypertension). Usual Adult Dose of Losartan for Diabetic Nephropathy: Initial dose: 50 mg orally once a day. Unauthorized For Adult 76 years and over Initially 25 mg once daily for several weeks, then increased if necessary to 100 mg once daily. Customer Service The dose should generally be titrated at weekly intervals (i.e. In the HEAAL study ( Lancet , online , 17 November 2009), investigators randomised 3,846 heart failure patients who were intolerant of angiotensin-converting enzyme (ACE) inhibitors to receive 150mg or 50mg of losartan each day. WebMD explains what they are and how they work. The dose should generally be titrated at weekly intervals (i.e. Initial dose: 50 mg orally once a day. IHD indicates ischemic heart disease; LVEF, left ventricular ejection fraction; NYHA, New York Heart Association functional classification; PCWP, pulmonary capillary wedge pressure; CI, cardiac index; HR, heart rate; and bpm, beats per minute. The randomized, double-blind Heart failure Endpoint evaluation with Angiotensin II Antagonist Losartan (HEAAL) study showed 150 mg of losartan to have favourable effects compared with the currently recommended dose of 50 mg per day. Losartan was not associated with improved survival compared to captopril in elderly heart-failure patients, but was significantly better tolerated. Treatment with 50 mg of losartan (medium dose) was also associated with a higher mortality risk. We tested the hypothesis that incremental losartan dosing would reduce the risk of the primary combined … Neurohormone levels (log scale) in patients with heart failure receiving placebo and 2.5, 10, 25, and 50 mg losartan. Lancet 2009;374:1840–8. Plots of mean change in heart rate (beats per minute) from pretreatment baseline levels (A) after short-term therapy and (B) after 12 weeks of therapy. If it continues for a long time, the heart and arteries may not function properly. Neaton JD, 3.   Hypertension: Adults: 50 milligrams (mg) a day; Children: Starting at 0.7 mg per kilogram of weight per day, up to 50 mg. Hypertensive patients with enlarged heart have a usual starting dose of 50 mg a day. Half-life: Losartan, 1.5-2 hr; E-3174, 6-9 hr; increased in end-stage renal failure or CHF Dialyzable: HD, no; PD, no Renal clearance: Losartan, 43-75 mL/min; E-3174, 18-25 mL/min Compared with high doses of candesartan (16-32 mg), low-dose (12.5 mg) and medium-dose losartan (50 mg) were associated with increased mortality (HR, 2.79; 95% CI, 2.19-3.55 and HR, 1.39; 95% CI, 1.11-1.73, respectively); use of high-dose losartan (100 mg) was similar in risk (HR, 0.71; 95% CI, 0.50-1.00). Plots of mean change in mean arterial pressure (mm Hg) from pretreatment baseline levels (A) after short-term therapy and (B) after 12 weeks of therapy. Conclusions This study showed that oral losartan administered to patients with symptomatic heart failure resulted in beneficial hemodynamic effects with short-term administration, with additional beneficial hemodynamic effects seen after 12 weeks of therapy. This work was funded by a project grant from Merck Research, National Center Inclusion criteria were age over 65, history of congestive heart failure (NYHA Class II-IV), and no previous ACE inhibitor therapy. Among patients with HF, the overall use of losartan compared with candesartan was not associated with an increased mortality risk. Will my dose go up or down? Participants will be assigned to one of two groups: high-dose, in which subjects will receive treatment of 200 mg/day of losartan, and low-dose, in which subjects will receive treatment of 50 mg/day of losartan. Absolute levels are presented for short-term baseline before initiation of trial medications. The finding immediately created a new, standard losartan dosage for these patients, experts said.

Initially 50 mg once daily for several weeks, then increased if necessary to 100 mg once daily. Dickstein K, 4. et al . The usual initial dose of losartan in patients with heart failure is 12.5 mg once daily. If you have any . 7 Incremental losartan doses of up to 150 mg in patients with heart failure result in progressive increases in plasma renin activity and in circulating concentrations of angiotensin II. Differences from short-term baseline are presented at 5 and 24 h after short-term dose and after 12 weeks of therapy (long-term) before dose (predose) and 5 and 24 h after dose. It was estimated that treatment with 150 mg instead of 50 mg per day losartan would prevent one primary event for every 31 patients treated for 4 years.
