Composition
Active substances: losartan, amlodipine.
Dosage and administration
Inside, 1 time / day, regardless of the time of administration, write with a small amount of water.
The recommended dose of Lortenza is 1 tablet / day.
The drug Lortenza at a dose of 5 mg + 50 mg is prescribed to patients who have not achieved adequate control of blood pressure when using amlodipine at a dose of 5 mg or losartan at a dose of 50 mg in monotherapy.
The drug Lortenza at a dose of 5 mg + 100 mg is prescribed to patients who have not achieved adequate control of blood pressure when using losartan at a dose of 100 mg or the drug Lortens at a dose of 5 mg + 50 mg.
The drug Lortenza at a dose of 10 mg + 50 mg is prescribed to patients who have not achieved adequate control of blood pressure when using amlodipine at a dose of 10 mg or Lortens at a dose of 5 mg + 50 mg.
The drug Lortenza at a dose of 10 mg + 100 mg is prescribed to patients who have not achieved adequate control of blood pressure when using the drug Lortenza at a dose of 5 mg + 100 mg or 10 mg + 50 mg.
The dose is selected after previously titrated doses of the individual components of the drug. If a change in the dose of one of the active substances in a fixed combination preparation is required (for example, in connection with a newly diagnosed disease, a change in the patient's condition or drug interaction), an individual selection of doses of the individual components is necessary. The maximum daily dose is 10 mg + 100 mg.
Patients taking losartan and amlodipine at the same time can be transferred to a Lortenza drug containing losartan and amlodipine in the same doses.
In patients with impaired renal function with CC from 50 to 20 ml / min, dose adjustment is not required. The drug Lortenza is contraindicated in patients with CC less than 20 ml / min and in patients undergoing hemodialysis.
Patients with impaired liver function (less than 9 Child-Pugh scores) should have a lower history of losartan. Due to the lack of a dosage containing 25 mg of losartan in the drug Lortenza, this dose should be prescribed in monotherapy with losartan. The use of the drug Lortenza is possible in patients with impaired liver function (less than 9 points on the Child-Pugh scale), who, by the decision of the doctor, recommended the use of losartan in a dose of 50 mg.
In patients with reduced BCC (for example, due to treatment with high doses of diuretics, etc.), the initial dose of losartan should be reduced to 25 mg 1 time / day. Due to the lack of a dosage containing 25 mg of losartan in the drug Lortenza, this dose should be prescribed in monotherapy with losartan. Before using the drug Lortensa, it is necessary to restore the BCC and the sodium content in the blood plasma.
In elderly patients, dose adjustment of Lortenza is not required, but the dose should be increased carefully.
The drug Lortenza should not be prescribed to children and adolescents under the age of 18 years, because there are no data on the efficacy and safety of use in this group of patients.

Drug interaction
The antihypertensive effect may be enhanced when used simultaneously with other antihypertensive drugs, so the simultaneous administration of various antihypertensive drugs should be justified.
Amlodipine
May be used safely in the treatment of hypertension with thiazide diuretics, β-blockers, or ACE inhibitors. Unlike other BKK, a clinically significant interaction of amlodipine (III generation of BKK) was not found when combined with NSAIDs, including with indomethacin. It is possible to enhance the hypotensive effect of BCC when combined with thiazide and loop diuretics, ACE inhibitors and nitrates, as well as increase their hypotensive effect when combined with? 1-adrenoblockers, antipsychotics.
The combined use of amlodipine with CYP3A4 inhibitors requires careful monitoring of symptoms of hypotension and peripheral edema. With the simultaneous administration of diltiazem at a dose of 180 mg per day and amlodipine at a dose of 5 mg per day for elderly patients, the systemic exposure of amlodipine is increased by 60%. Erythromycin, when used together, increases the Cmax of amlodipine in young patients by 22%, and in elderly patients by 50%. At the same time, strong CYP3A4 inhibitors (ketoconazole, itraconazole, ritonavir) can increase the concentration of amlodipine in plasma to an even greater extent.
Despite the fact that an accurate quantitative assessment of the interaction of amlodipine and CYP3A4 inducers (e.g. rifampicin, St. John's wort perforated) has not been obtained, constant monitoring of blood pressure is recommended against the background of their combined use. ? -adrenoblockers with simultaneous administration with amlodipine can cause an exacerbation of the course of heart failure.
Although a negative inotropic effect was not usually observed in the study of amlodipine, nevertheless, some BCCs may increase the severity of the negative inotropic effect of antiarrhythmic drugs that cause a prolongation of the QT interval (e.g. amiodarone and quinidine).
A single dose of 100 mg of sildenafil in patients with arterial hypertension does not affect the pharmacokinetics of amlodipine.
Repeated use of amlodipine at a dose of 10 mg and atorvastatin at a dose of 80 mg is not accompanied by significant changes in the pharmacokinetics of atorvastatin.
Ethanol (drinks containing alcohol): amlodipine, with a single and repeated use at a dose of 10 mg, does not affect the pharmacokinetics of ethanol.
Antipsychotics and isoflurane: increased hypotensive effect of dihydropyridine derivatives.
With the on / in the introduction of dantrolene during treatment with amlodipine, collapse, arrhythmias, decreased cardiac contractions and hyperkalemia are possible.
Calcium preparations may decrease the effect of BCC.
With the combined use of amlodipine with lithium preparations, an increase in the manifestation of neurotoxicity is possible (nausea, vomiting, diarrhea, ataxia, tremor, tinnitus).
Amlodipine does not alter cyclosporine pharmacokinetics.
Does not affect the concentration of digoxin in the blood serum and its renal clearance.
Does not significantly affect the effect of warfarin (PV).
Cimetidine does not affect the pharmacokinetics of amlodipine.
In vitro studies, amlodipine does not affect plasma protein binding of digoxin, phenytoin, warfarin, and indomethacin.
Grapefruit juice: simultaneous single intake of 240 mg of grapefruit juice and 10 mg of amlodipine inside is not accompanied by a significant change in the pharmacokinetics of amlodipine.
Aluminum- or magnesium-containing antacids: a single dose of them does not significantly affect the pharmacokinetics of amlodipine.
Losartan
As with other agents that block the formation of angiotensin II and its effects, the concomitant use of potassium-sparing diuretics (e.g. spironolactone, triamteren, amiloride), potassium supplements and potassium-containing salt substitutes can lead to an increase in serum potassium. In some patients with impaired renal function who have been treated with NSAIDs, including selective COX-2 inhibitors, the simultaneous administration of ACE inhibitors and / or ARA drugs, including losartan, may cause further deterioration of kidney function up to the development of acute renal failure. Usually this effect is reversible. NSAIDs, including selective COX-2 inhibitors, can reduce the effect of angiotensin II receptor blockers, including losartan. Therefore, the hypotensive effect of angiotensin II receptor antagonists can be attenuated with the simultaneous use of NSAIDs, in particular selective COX-2 inhibitors. Thus, the simultaneous use of the drug with NSAIDs should be carried out with caution in patients with impaired renal function.
Double blockade of RAAS: found that in patients with atherosclerosis, heart failure or diabetes with target organ damage, dual RAAS blockade (concomitant use of ACE inhibitors and ARA drugs) is associated with more frequent complications of therapy in the form of arterial hypotension, syncope, syncope, and hyperkalemia and renal impairment (including acute renal failure) compared with monotherapy with each drug. In this regard, combined treatment with ACE inhibitors and ARA drugs requires an individualized approach and constant monitoring of the functional activity of the kidneys.
No pharmacokinetically significant drug interactions with drugs such as hydrochlorothiazide, digoxin, warfarin, cimetidine, and phenobarbital have been observed.
Taking rifampin, an inducer of drug metabolism, reduces the concentration of losartan and its active metabolite.
2 inhibitors, CYP3A4 isoenzyme, were studied in humans. Ketoconazole does not affect the biotransformation of losartan administered iv before the active metabolite, and erythromycin does not have a clinically significant effect on the pharmacokinetics of losartan when taken orally.
Fluconazole, an inhibitor of the CYP2C9 isoenzyme, reduces the concentration of the active metabolite and increases the concentration of losartan in the blood plasma, however, the pharmacodynamic significance of the combined use of losartan and inhibitors of the CYP2C9 isoenzyme has not been established. It was shown that in individuals whose body does not convert losartan into an active metabolite, there is a very rare and specific defect in the CYP2C9 isoenzyme. These data indicate that the biotransformation of losartan to an active metabolite is predominantly mediated by the CYP2C9 isoenzyme, rather than CYP3A4.
