Dosage and Administration

Losartan is taken orally, regardless of meal times.

drug can be used as monotherapy or concomitantly with other antihypertensive drugs.

Unless otherwise purposes, the daily dose received in one reception.

In most cases hypertension standard initial and maintenance daily dose is 50 mg.Typically, the maximum antihypertensive effect is reached after 3-6 weeks after initiation of therapy.In some patients, to achieve a greater effect can be increased up to a maximum dose - 100 mg per day.

By reducing the volume of circulating blood (for example, high doses of diuretics) Losartan starting to take a dose of 25 mg per day.

No need for individual selection of the starting dose in elderly patients and in patients with renal insufficiency, including patients on dialysis.

When liver failure (less than 9 points on a scale Child-Pugh) during hemodialysis, as well as patients from 75 years of drug is recommended to be administered in a lower initial dose - 25 mg.

Standard daily starting dose of Losartan to reduce the risk associated cardiovascular morbidity and mortality in patients with left ventricular hypertrophy and arterial hypertension is 50 mg.Further increase in the dose recommended by 2 times (1 or 2 doses, depending on the degree of blood pressure lowering) or the addition of hydrochlorothiazide.

standard initial daily dose of Losartan to protect the kidney in patients with type 2 diabetes mellitus with proteinuria is 50 mg.Further increase in the dose recommended by 2 times depending on the degree of blood pressure reduction.Losartan can be used simultaneously with other antihypertensive drugs (alpha- and beta-blockers, diuretics, centrally acting antihypertensive drugs, blockers "slow" calcium channels), insulin and other hypoglycemic drugs (inhibitors of glucosidase glitazones and sulfonylureas).

In chronic heart failure the initial daily dose is 12.5 mg Losartan.Usually the dose is titrated at weekly intervals to the usual maintenance dose - 50 mg 1 time per day (depending on individual tolerance).

Side effects

Losartan is generally well tolerated, side effects are transient and bland character and do not require treatment discontinuation.

In applying the drug may develop disorders of some body systems that appear with varying frequency (& gt; 1% - frequently;

  • digestive system: often - abdominal pain, dyspepsia, diarrhea, nausea, rarely - dry mucous membranesmouth, anorexia, flatulence, toothache, gastritis, constipation, abnormal liver function, hepatitis, vomiting;
  • Cardiovascular system: frequent - palpitations, tachycardia, rarely - angina, symptomatic hypotension (especially in patients with intravascular dehydration,for example, in severe heart failure, or when taking high doses of diuretics), dose-related orthostatic hypotension, bradycardia, myocardial infarction, arrhythmia, vasculitis;
  • central nervous system and sensory organs: often - headache, dizziness, insomnia, rare - anxiety, impairedsleep, memory impairment, somnolence, peripheral neuropathy, gipostezii, paraesthesia, tremor, depression, ataxia, syncope, conjunctivitis, taste disturbance and vision, tinnitus, migraine;
  • urinary system: rarely - urinary tract infections, urgent need to urinate, functional disorders of the kidneys;
  • Respiratory system: often - cough, swelling of the nasal mucosa, bronchitis, sinusitis, sore throat, infection of the upper respiratory tract;
  • hemopoietic system: rarely - anemia, eosinophilia, thrombocytopenia, Henoch-Sch├Ânlein purpura;
  • reproductive system: rarely - impotence, decreased libido;
  • Musculoskeletal System: often - muscle cramps, pain in the legs and back;rarely - arthritis, arthralgia, pain in the knee and shoulder, fibromyalgia;
  • Skin: rare - increased sweating, dry skin, erythema, ecchymosis, photosensitivity, alopecia;
  • Allergic reactions: seldom - skin rash, urticaria, pruritus, angioedema (including swelling of the vocal cord and larynx, causing airway obstruction and / or swelling of the lips, face, tongue and / or throat);
  • General disorders: often - peripheral edema, asthenia, fatigue, weakness, pain in the chest;
  • Other: rarely - nosebleeds, exacerbation of gout.

also possible development of violations by the laboratory parameters: & gt; 1% and 0.1% and

In developing or worsening of these side effects, as well as the development of atypical symptoms should see a doctor.


In rare cases, the use of Losartan developing disturbances in the form of anaphylactic reactions, angioedema involving the larynx and pharynx, causing airway obstruction and / or swelling of the face, lips, tongue and / or throat.Therefore, if there is indication of angioedema drug history should be taken with extreme caution.

In patients with decreased volume of circulating blood (for example, receiving high doses of diuretics) may develop symptomatic hypotension.It is necessary to carry out the correction of these states to losartan or to begin receiving therapy with lower doses.

Disturbances of water and electrolyte balance are characteristic of patients with renal insufficiency, diabetes mellitus type 2, or without it.When losartan these patients need to be very careful because of the risk of hyperkalemia.

During therapy need to regularly monitor the content of potassium in the blood, especially in elderly patients and in functional disorders of the kidneys.Without prior approval from a physician should not take potassium supplements or salt substitutes containing potassium.

If there is indication of liver disease, a history of Losartan should be taken in lower doses, it is associated with an increase in plasma concentrations of the drug.

During therapy need to regularly at regular intervals to monitor the concentration of creatinine in the blood serum.

Use caution when driving and performing other potentially hazardous activities that require high concentration and rapid psychomotor reactions, because of the possible development of dizziness, especially in patients taking diuretic medications and switched to losartan.

Drug Interactions

With simultaneous use of Losartan with some drugs may cause the following effects:

  • Rifampicin, fluconazole: a decrease in the level of the active metabolite;
  • Potassium-sparing diuretics (e.g., spironolactone, amiloride, triamterene, eplerenone) or preparations that enhance the potassium content (e.g., heparin), potassium supplements, and a potassium salt: potassium increase in serum;
  • lithium preparations: decrease sodium excretion and increased serum concentrations of lithium (necessary to carry out its monitoring of serum concentration);
  • Nonsteroidal anti-inflammatory drugs, including selective cyclooxygenase-2 inhibitors: decrease of antihypertensive effect;in patients with impaired renal function treated with NSAIDs may further deterioration of renal function;
  • Other antihypertensives: an increase in the severity of antihypertensive action;
  • drugs that reduce blood pressure (eg, tricyclic antidepressants, antipsychotics, baclofen, amifostine): increased risk of hypotension;
  • Drugs acting on the renin-angiotensin-aldosterone system: increased risk of hypotension, hyperkalemia, syncope and renal dysfunction (including acute renal failure);necessary to carry out careful monitoring of blood pressure, fluid and electrolyte balance and renal function.

Losartan may be used concomitantly with other antihypertensive drugs.

combined use of aliskiren in patients with diabetes and renal insufficiency (glomerular filtration rate at less than 60 mL per minute) is not recommended.
