What is Arbli?

From the FDA label:Losartan potassium is an angiotensin II receptor blocker acting on the AT 1 receptor subtype. Losartan potassium, a non-peptide molecule, is chemically described as 2-butyl-4-chloro-1-[ p -( o -1 H -tetrazol-5-ylphenyl)benzyl]imidazole-5-methanol monopotassium salt. Its empirical formula is C 22 H 22 ClKN 6 O, and its structural formula is: Losartan potassium is a white to off-white free-flowing crystalline powder with a molecular weight of 461.01. It is freely soluble in water, soluble in alcohols, and slightly soluble in common organic solvents, such as acetonitrile and methyl ethyl ketone. Oxidation of the 5-hydroxymethyl group on the imidazole ring results in the active metabolite of losartan. Arbli is available as a white, translucent oral suspension with a peppermint odor. Each mL contains 10 mg losartan potassium (equivalent to 9.2 mg losartan), inactive ingredients are: hypromellose, methyl paraben, natural peppermint flavor, polyethylene glycol, povidone, propyl paraben, propylene glycol, purified water, simethicone, sodium phosphates, sucralose, and xanthan gum. structural formula

( 2.3 ) Add hydrochlorothiazide 12.5 mg and/or increase Arbli to 100 mg orally followed by an increase to hydrochlorothiazide 25 mg if further blood pressure response is needed. ( 2.3 , 14.2 ) Nephropathy in Type 2 Diabetic Patients Usual dose: 50 mg orally once daily. ( 2.4 ) Increase dose to 100 mg orally once daily if further blood pressure response is needed. ( 2.4 ) 2.1 Important Administration Information Instruct patients or caregivers to use oral dosing syringe(s) or an oral dosing cup to measure the prescribed amount of medication. Inform patients that oral dosing syringe(s) or an oral dosing cup may be obtained from their pharmacy. 2.2 Hypertension Adult Hypertension The usual starting dose of Arbli is 50 mg orally once daily. The dosage can be increased to a maximum dose of 100 mg orally once daily as needed to control blood pressure [see Clinical Studies (14.1) ] . A starting dose of 25 mg once daily is recommended for patients with possible intravascular depletion (e.g., on diuretic therapy). Pediatric Hypertension The usual recommended starting dose is 0.7 mg per kg orally once daily (up to 50 mg total) administered…

Side effects

Most common adverse reactions (incidence ≥2% and greater than placebo) are: dizziness, upper respiratory infection, nasal congestion, and back pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Scienture LLC at 1-833-754-4917 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Hypertension Arbli has been evaluated for safety in more than 3,300 adult patients treated for essential hypertension and 4058 patients/subjects overall. Over 1,200 patients were treated for over 6 months and more than 800 for over one year. Treatment with Arbli was well-tolerated with an overall incidence of adverse events similar to that of placebo. In controlled clinical trials, discontinuation of therapy for adverse events occurred in 2.3% of patients treated with Arbli and 3.7% of patients given placebo. In 4 clinical trials involving over 1,000 patients on various doses (10 mg to 150 mg) of losartan potassium and over 300 patients given placebo, the adverse events that occurred in ≥2% of patients treated with Arbli and more commonly than placebo were: dizziness (3% vs. 2%), upper respiratory infection…

FDA Boxed Warning (the FDA’s most serious warning)

Boxed (black-box) warning — from the FDA label

When pregnancy is detected, discontinue Arbli as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus [see Warnings and Precautions (5.1) ] . WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning. When pregnancy is detected, discontinue Arbli as soon as possible. Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus. ( 5.1 )

Warnings

Important safety information

Hypotension: Correct volume or salt depletion prior to administration of Arbli. ( 5.2 ) Monitor renal function and potassium in susceptible patients. ( 5.3 , 5.4 ) 5.1 Fetal Toxicity Arbli can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death. When pregnancy is detected, discontinue Arbli as soon as possible [see Use in Specific Populations (8.1) ] . 5.2 Hypotension in Volume-or Salt-Depleted Patients In patients with an activated renin-angiotensin system, such as volume-or salt-depleted patients (e.g., those being treated with high doses of diuretics), symptomatic hypotension may occur after initiation of treatment with Arbli. Correct volume or salt depletion prior to administration of Arbli [see Dosage and Administration (2.2) ] . 5.3 Renal Function Deterioration Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system and by diuretics. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, or volume depletion) may be at particular risk of developing acute renal failure on Arbli. Monitor renal function periodically in these patients. Consider withholding or discontinuing therapy in patients who develop a clinically significant decrease in renal function on Arbli [see Drug Interactions (7.3) and Use in Specific Populations (8.7) ] . 5.4 Hyperkalemia Monitor serum potassium periodically and treat appropriately. Dosage reduction or discontinuation of Arbli may be required [see Adverse Reactions (6.1) ] . Concomitant use of other drugs that may increase serum potassium may lead to hyperkalemia [see Drug Interactions (7.1) ] .

Who should not take Arbli

Arbli is contraindicated: In patients who are hypersensitive to any component of this product. For co-administration with aliskiren in patients with diabetes. Hypersensitivity to any component. ( 4 ) Co-administration with aliskiren in patients with diabetes. ( 4 )

Overdose — what happens if you take too much

Significant lethality was observed in mice and rats after oral administration of 1,000 mg/kg and 2,000 mg/kg, respectively, about 44 and 170 times the maximum recommended human dose on a mg/m 2 basis. Limited data are available in regard to overdosage in humans. The most likely manifestation of overdosage would be hypotension and tachycardia; bradycardia could occur from parasympathetic (vagal) stimulation. If symptomatic hypotension should occur, supportive treatment should be instituted. Neither losartan nor its active metabolite can be removed by hemodialysis.

Interactions

Agents Increasing Serum Potassium: Risk of hyperkalemia. ( 7.1 ) Lithium: Risk of lithium toxicity. ( 7.2 ) NSAIDs: Increased risk of renal impairment and reduced diuretic, natriuretic, and antihypertensive effects. ( 7.3 ) Dual Inhibition of the Renin-Angiotensin System: Increased risk of renal impairment, hypotension, syncope, and hyperkalemia. ( 7.4 ) 7.1 Agents Increasing Serum Potassium Co-administration of losartan with other drugs that raise serum potassium levels may result in hyperkalemia. Monitor serum potassium in such patients. 7.2 Lithium Increases in serum lithium concentrations and lithium toxicity have been reported during concomitant administration of lithium with angiotensin II receptor antagonists. Monitor serum lithium levels during concomitant use. 7.3 Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors) In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with angiotensin II receptor antagonists (including losartan) may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving losartan and NSAID therapy. The antihypertensive effect of angiotensin II receptor antagonists, including losartan, may be attenuated by NSAIDs, including selective COX-2 inhibitors. 7.4 Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, syncope, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. The Veterans Affairs Nephropathy in Diabetes (VA NEPHRON-D) trial enrolled 1,448 patients with type 2 diabetes, elevated urinary-albumin-to-creatinine ratio, and decreased estimated glomerular filtration rate (GFR 30 to 89.9 mL/min), randomized them to lisinopril or placebo on a background of losartan therapy and followed them for a median of 2.2 years. Patients receiving the combination of losartan and lisinopril did not obtain any additional benefit compared to monotherapy for the combined endpoint of decline in GFR, end stage renal disease, or death, but experienced an increased incidence of hyperkalemia and acute kidney injury compared with the monotherapy group. In most patients no benefit has been associated with using two RAS inhibitors concomitantly. In general, avoid combined use of RAS inhibitors. Closely monitor blood pressure, renal function, and electrolytes in patients on losartan and other agents that affect the RAS. Do not co-administer aliskiren with losartan in patients with diabetes. Avoid use of aliskiren with losartan in patients with renal impairment (GFR <60 mL/min).

How long does Losartan Potassium stay in your body?

The elimination half-life of losartan potassium is about 2 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. Losartan has an active metabolite (E-3174/EXP3174) with a longer terminal half-life of about 6 to 9 hours, and the FDA label states this metabolite is responsible for most of the blood-pressure-lowering effect.

Frequently asked questions

What does Arbli treat?
Arbli (Losartan Potassium) may be used to treat diabetic nephropathies, heart failure, hypertension, left ventricular hypertrophy, left ventricular dysfunction, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
How does Arbli work?
Arbli is a angiotensin 2 receptor blocker. Angiotensin II receptor blockers (ARBs) block the AT1 receptor that the hormone angiotensin II uses to tighten blood vessels and make the body hold onto salt and water. With that receptor blocked, vessels relax and widen, so blood pressure falls.
How much does Arbli cost?
Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published. What IS published is what the pharmacy paid to acquire it: about $1.00 for 30, per the CMS NADAC survey. Treat that as the floor, not the quote — ask the pharmacist for the cash price as well as your copay, because for cheap generics the cash price often wins.
Is there a coupon or discount for Arbli?
pharmaranks is an independent ratings site, not a pharmacy — we don't issue coupons or sell Arbli. To pay less, ask your prescriber or pharmacist whether a generic equivalent exists, check the manufacturer's copay/savings card and patient-assistance program, and compare a pharmacy discount card against your insurance copay. Prices vary by pharmacy, insurance, and location, so always confirm at the counter. This is general reference, not medical or financial advice.
