Hypertension (high blood pressure), Heart failure, Prevention of heart attacks and strokes
- Arterial hypertension.

1 film-coated tablet, 100 mg contains:
losartan potassium 100 mg;
corn starch 50.8 mg,
croscarmellose sodium 11 mg,
mannitol 60 mg,
p> magnesium stearate 2 mg,
povidone 6.2 mg,
microcrystalline cellulose 50 mg;

How to take, the dosage
Overly, regardless of meals. Tablets are swallowed without chewing, with water. Frequency of intake is 1 time per day, preferably at the same time, in the morning.
The starting and maintenance dose is 50 mg/day. If necessary, the daily dose may be increased to a maximum of 100 mg. If a single dose does not give the target BP, the daily dose should be divided into 2 doses: 25 mg (25 mg lozartan or 50 mg lozartan with rice) 2 times daily or 50 mg 2 times daily.
Lowering cardiovascular risk and mortality in patients with arterial hypertension and left ventricular hypertrophy
The initial dose of the drug is 50 mg once daily. Subsequently, low-dose hydrochlorothiazide may be added or the dose of Lozartan Canon may be increased to a maximum of 100 mg in one or two doses based on a decrease in BP.
Chronic Heart Failure
The starting dose for patients with chronic heart failure is 12.5 mg (losartan in 25 mg tablets with rice may be used) once daily. The dose is titrated 2 times, depending on patient tolerance, at weekly intervals, i.e., 12.5 mg/day, 25 mg/day, 50 mg/day to an average maintenance dose of 50 mg/day. No dose adjustment is required in elderly patients with renal insufficiency.
In patients with type 2 diabetes mellitus with proteinuria to slow the progression of renal failure
The initial dose is 50 mg once daily with further increase to a maximum dose of 100 mg/day (depending on the degree of BP reduction) in one or two doses.
Particular patient groups
In patients with decreased circulating blood volume (RBC) (e.g., when taking high-dose diuretics), the recommended starting dose of Losartan Canon is 25 mg (losartan 25 mg tablets or 50 mg tablets with a rice may be used).
Patients with hepatic impairment (less than 9 points on the Child-Pugh scale), hemodialysis procedures, and patients older than 75 years are recommended a lower starting dose of 25 mg (the use of losartan in 25 mg tablets or in 50 mg tablets with a ribbon is possible) once daily.
There is insufficient experience in using the drug in patients with severe hepatic impairment; therefore, the drug is not recommended in this category of patients (see section “Contraindications”).
In patients with moderate renal impairment (CKR 20-30 ml/min) no dose adjustment is required.
Can be used concomitantly with other hypotensive agents.
No clinically significant drug interactions of losartan with hydrochlorothiazide, digoxin, warfarin, cimetidine, phenobarbital, ketoconazole and erythromycin have been reported. Rifampicin and fluconazole have been reported to decrease plasma concentrations of the active metabolite. The clinical significance of these interactions is not yet known.
As with other agents that block angiotensin II formation and effects, concomitant administration of potassium-saving diuretics (spironolactone, triamterene, amiloride), potassium supplements and salts containing potassium may result in increased serum potassium ions.
Hypotensive agents may increase the antihypertensive effects of losartan.Also, tricyclic antidepressants, neuroleptics, baclofen, and amifostine may increase the antihypertensive effects of losartan, which lower blood pressure as a primary or side effect and may increase the risk of arterial hypotension.
The simultaneous use of angiotensin II receptor antagonists and nonsteroidal anti-inflammatory drugs (NSAIDs) (including selective cyclooxygenase-2 inhibitors, acetylsalicylic acid as an anti-inflammatory agent) may decrease the antihypertensive effects of losartan. In patients with impaired renal function, concomitant use of angiotensin II antagonists or diuretics and NSAIDs may cause further impairment of renal function, including acute renal failure and increased serum potassium. This combination should be used with caution, especially in elderly patients.
With concomitant use of lithium with ACE inhibitors a reversible increase in serum lithium concentration and development of toxicity has been registered; in very rare cases this was observed with angiotensin II receptor antagonists. Caution should be exercised when using lithium concomitantly with losartan. If this combination is necessary, it is recommended that serum lithium concentrations be monitored.
Mutually enhances the effect of beta-adrenoblockers and sympatholytics; coadministration of losartan with diuretics causes an additive effect.
Dual RAAS blockade (e.g., by combining an angiotensin II receptor antagonist with ACE inhibitors or aliskiren) in patients with diagnosed atherosclerosis, heart failure or diabetes mellitus with target organ damage is associated with a higher incidence of arterial hypotension, syncope, hyperkalemia and renal dysfunction (including the development of acute renal failure) compared to the use of single RAAS blockade. Double RAAS blockade should be controlled individually in each case with careful monitoring of blood pressure, blood water-electrolyte balance and renal function.
Patients with decreased RBC (e.g., those receiving high-dose diuretics) may experience symptomatic arterial hypotension, so replete the RBC or initiate lower-dose treatment with losartan canon before starting treatment.
In patients with cirrhosis, plasma concentrations of losartan are significantly increased, so it should be prescribed in lower doses if there is a history of liver disease.
Pharm plasma potassium and creatinine clearance should be monitored regularly during therapy, especially in elderly patients, patients with impaired renal function, patients with type 2 diabetes complicated by nephropathy; and these parameters should be monitored particularly carefully in patients with heart failure with concomitant renal impairment.
Preventive RAAS medications can increase urate and serum creatinine concentrations in patients with bilateral renal artery stenosis or arterial stenosis of the sole kidney.
There is no experience with losartan in patients after renal transplantation.
In patients with severe chronic heart failure, drugs that affect the RAAS can lead to severe arterial hypotension and acute renal failure. There are isolated reports of the development of oliguria and/or increasing azotemia and acute renal failure, including death.
There is insufficient experience with losartan in patients with heart failure with concomitant severe renal failure, in patients with severe chronic heart failure (NYHA functional class IV), in patients with heart failure with life-threatening arrhythmias. In these groups, caution should be exercised when using Lozartan Canon with beta-adrenoblockers.
As with all drugs with vasodilatory effects, Losartan Canon should be administered with caution in patients with aortic or mitral stenosis, or obstructive hypertrophic cardiomyopathy.
In patients with cerebrovascular disease of ischemic nature, excessive BP reduction may lead to stroke.
Physician supervision of dose titration is recommended.
Caution should be exercised when prescribing Lozartan Canon in patients with a history of angioedema, including when taking other medications, including ACE inhibitors.
Patients with primary hyperaldosteronism usually do not respond to hypotensive agents acting through inhibition of the renin-angiotensin system. Therefore, the use of Lozartan Canon is not recommended for the treatment of such patients.
Impact on driving and operating machinery
There have been no studies to evaluate the effect of the drug on driving and operating machinery.
Drowsiness and dizziness may occur, so caution should be exercised when performing tasks requiring increased attention, especially at the beginning of treatment, when increasing the drug dose and when driving vehicles.
