Mechanism of action

Lorista H - combination drug; has a hypotensive effect. Losartan is a selective antagonist of angiotensin II receptors (type AT1) for oral administration, non-protein nature. In vivo and in vitro losartan and its biologically active carboxyl metabolite (EXP-3174) block all physiologically significant effects of angiotensin II on AT1 receptors, regardless of the route of its synthesis: leads to an increase in plasma renin activity, decreases plasma aldosterone concentration, etc. Losartan indirectly induces activation of the AT2 receptor by increasing the level of angiotensin II. Losartan does not inhibit the activity of kininase II, an enzyme that is involved in the metabolism of bradykinin. Reduces total peripheral vascular resistance (OPSS), pressure in the "small" circle of blood circulation; reduces afterload, has a diuretic effect. Interferes with the development of myocardial hypertrophy, increases exercise tolerance in patients with chronic heart failure (CHF). Taking losartan once a day results in a statistically significant reduction in systolic and diastolic blood pressure (BP). Losartan evenly controls the pressure throughout the day, with the antihypertensive effect consistent with the natural circadian rhythm. The decrease in blood pressure (BP) at the end of the dose of the drug was approximately 70-80% of the effect at the peak of the drug, 5-6 hours after administration. "Cancellation" syndrome is not observed; Also, losartan does not have a clinically significant effect on heart rate (HR). Losartan is effective in men and women, as well as in the elderly (and> 65 years) and younger patients (and <65 years). Hydrochlorothiazide.Thiazide diuretic, the diuretic effect of which is associated with impaired reabsorption of sodium, chlorine, potassium, Magnesium ions, and water in the distal nephron; delays the excretion of Calcium ions, uric acid. It has antihypertensive properties; hypotensive effect develops due to the expansion of arterioles. Virtually no effect on normal blood pressure (BP). The diuretic effect occurs after 1-2 hours, reaches a maximum after 4 hours and lasts 6-12 hours. The antihypertensive effect occurs after 3-4 days, but it may take 3-4 weeks to achieve the optimal therapeutic effect.

Indications and usage

  • Arterial hypertension (for patients who are recommended combination therapy).
  • Reducing the risk of cardiovascular morbidity and mortality in patients with arterial hypertension and left ventricular hypertrophy.


Hypersensitivity to losartan, to agents derived from sulfonamides and other components of the drug, anuria, pronounced renal dysfunction (creatinine clearance (CK) less than 30 ml / min.), Hyperkalemia, dehydration (including while receiving high doses of diuretics), severe liver dysfunction, refractory hypokalemia, pregnancy, lactation, hypotension, age up to 18 years (efficacy and safety not established), lactase deficiency, galactosemia or malabsorption syndrome glucose / Galactose.

Pregnancy and Breastfeeding

Data on the use of losartan during pregnancy is not. Renal perfusion of the fetus, which depends on the development of the renin-angiotensin system, begins to function in the third trimester of pregnancy. The risk to the fetus increases when taking losartan in the second and third trimesters. At establishment of pregnancy therapy Loristoy ND has to be immediately stopped. If necessary, the appointment of the drug in the period of lactation is necessary to stop breastfeeding.

Dosage and administration

Inside, regardless of the meal.
LORISTA H can be combined with other antihypertensive drugs.
Arterial hypertension. Initial and maintenance dose - 1 table. Lorista H (50 / 12.5 mg) 1 time per day.The maximum antihypertensive effect is achieved within 3 weeks of therapy. To achieve a more pronounced effect, it is possible to increase the dose of the drug to 2 table. Lorista H (50 / 12.5 mg) 1 time per day. The maximum daily dose - 2 tablets. drug Lorista H.
In patients with reduced BCC (for example, when receiving large doses of diuretics), the recommended initial dose of losartan in patients with hypovolemia is 25 mg 1 time per day. In this regard, the treatment of Lorista H should begin after the abolition of diuretics and the correction of hypovolemia.
In elderly patients and patients with moderate renal insufficiency, including those on dialysis, no adjustment of the initial dose is required.
Reducing the risk of cardiovascular morbidity and mortality in patients with arterial hypertension and left ventricular hypertrophy. The standard initial dose of losartan is 50 mg 1 time per day.

Adverse reactions

From the blood and lymphatic system: infrequently - anemia, Sch&№246;nlein-Genoch disease.
Immune system: rarely, Anaphylactic reactions, angioedema (including swelling of the larynx and tongue, causing airway obstruction and / or swelling of the face, lips, pharynx).
Nervous system: often - headache, systemic and non-systemic dizziness, insomnia, fatigue; infrequently - migraine.
Cardiovascular: often - orthostatic hypotension (dose-dependent), palpitations, tachycardia; rarely - vasculitis.
Respiratory: often - cough, infections of the upper respiratory tract, pharyngitis, swelling of the nasal mucosa.
From the digestive tract: often - diarrhea, dyspepsia, nausea, vomiting, abdominal pain.
From the hepatobiliary system: rarely - hepatitis, abnormal liver function.
From the skin and subcutaneous fat: infrequently - urticaria, pruritus.
From the musculoskeletal system and connective tissue: often - myalgia, back pain; infrequently - arthralgia.
Other: often - asthenia, weakness, peripheral edema, chest pain.
Laboratory values: often - hyperkalemia, increased hemoglobin and hematocrit (clinically insignificant); sometimes a moderate increase in the level of urea and serum creatinine; very rarely - increased activity of liver enzymes and bilirubin.

Special notes

It can be administered with other antihypertensives. There is no need for a special selection of the initial dose for elderly patients. The drug can increase the concentration of urea and creatinine in the blood plasma in patients with bilateral renal artery stenosis or stenosis of the single kidney artery. Hydrochlorothiazide can increase arterial hypotension and disturbances of water and electrolyte balance (decrease in circulating blood volume, hyponatremia, hypochloraemic alkalosis, hypomagnesemia, hypokalemia), impair glucose tolerance, reduce urine calcium excretion and cause a transient, insignificant increase in calcium concentration in the blood plasma, reduce the excretion of calcium in urine and cause a transient, insignificant increase in calcium concentration in the blood plasma, decrease the excretion of calcium in the urine and cause a transient, insignificant increase in calcium concentration in the blood plasma, decrease the excretion of calcium in the urine and cause a transient, insignificant increase in calcium concentration in the blood plasma, reduce the excretion of calcium in the urine the concentration of cholesterol and triglycerides, provoke the occurrence of hyperuricemia and / or gout. Taking medications directly acting on the renin-angiotensin system during the II and III trimesters of pregnancy can lead to fetal death. In the event of pregnancy, the drug is indicated. Diuretics are usually not recommended for pregnant women due to the risk of jaundice in the fetus and newborn, thrombocytopenia in the mother. Diuretic therapy does not prevent the development of toxicosis of pregnancy.

Drug interactions

Losartan In clinical studies, pharmacokinetic interactions revealed no clinically significant drug interactions with hydrochlorothiazide, Digoxin, Warfarin, cimetidine, phenobarbital, Ketoconazole, and Erythromycin . Rifampicin and Fluconazole reduce the level of the active metabolite (this interaction has not been studied clinically). The combination of losartan with potassium-sparing diuretics (spironolactone, triamterene, amiloride), potassium-sparing additives or potassium salts can lead to hyperkalemia. NSAIDs, including selective cyclooxygenase-2 inhibitors, may reduce the effect of diuretics and other antihypertensive drugs, including losartan. In patients with impaired renal function who received NSAID therapy (including cyclooxygenase-2 inhibitors), treatment with angiotensin II receptor antagonists can lead to a further deterioration in renal function, including acute renal failure, which is usually reversible. The hypotensive effect of losartan, like other antihypertensive drugs, can be reduced by taking Indomethacin .

Hydrochlorothiazide With thiazide diuretics, drugs such as ethanol, barbiturates and narcotic drugs can potentiate the risk of developing orthostatic hypotension. Hypoglycemic agents (for oral administration and insulin) - may require dose adjustment of hypoglycemic agents. Other antihypertensives - additive effect. Kolestiramin and colestipol - in the presence of anionic exchange resins the absorption of hydrochlorothiazide is disturbed. Corticosteroids, ACTH (adrenocorticotropic hormone) - a pronounced decrease in electrolyte levels, in particular hypokalemia. Pressory amines (for example, epinephrine, norepinephrine) - reducing the severity of the response to receiving pressor amines. Muscle relaxants of non-depolarizing type of action (for example, tubocurarine) - increased effect of muscle relaxants. Lithium - diuretics reduce the renal clearance of lithium and increase the risk of developing the toxic effect of lithium; simultaneous use is not recommended. NSAIDs (including cyclooxygenase-2 inhibitors) - can reduce the diuretic, natriuretic and hypotensive effects of diuretics. Due to the effect on calcium metabolism, their intake may distort the results of the study of the function of the parathyroid glands.

Symptoms: pronounced decrease in blood pressure, tachycardia; bradycardia due to parasympathetic (vagal) stimulation.
Treatment: forced diuresis, symptomatic therapy, hemodialysis is ineffective.

Symptoms: the most frequent symptoms are due to electrolyte deficiency (hypokalemia, hypochloremia, hyponatremia) and dehydration due to excessive diuresis. With simultaneous intake of cardiac glycosides, hypokalemia can aggravate the course of arrhythmias.
Treatment: symptomatic.

Store in a dry place at a temperature not exceeding 30 ° C.
