Children. There are no data on the pharmacokinetics of the preparation in children.
Elderly patients (over 65 years old). The time to reach Cmax of amlodipine in blood plasma is approximately the same in younger patients and the elderly. In elderly patients, the clearance of amlodipine tends to decrease, which leads to an increase in AUC and a lengthening of T½. The average systemic AUC of valsartan in the elderly is 70% higher than in younger patients, therefore, caution must be exercised when increasing the dose.
Renal failure Renal impairment does not significantly affect the pharmacokinetics of amlodipine. For a compound whose renal clearance is only 30% of the total plasma clearance, no correlation was observed between the state of renal function and systemic exposure to valsartan.
Liver dysfunction. In patients with hepatic impairment, the clearance of amlodipine decreases, which leads to an increase in AUC by approximately 40-60%. In patients with mild and moderate chronic liver diseases, the exposure of valsartan (determined by the AUC values) is, on average, twice that of healthy volunteers (selected by age, sex and body weight). Patients with liver disease need caution when using the preparation.
Essential arterial hypertension in adult patients whose blood pressure is not regulated by monotherapy with amlodipine or valsartan.
Patients in whom blood pressure is inadequately controlled with monopreparations of amlodipine or valsartan can be transferred to combination therapy with the preparation kombisart. the recommended dose is 1 tablet per day. Kombisart tablets can be taken with or without food. it is recommended to take kombisart with a little water.
Patients taking valsartan and amlodipine separately can be transferred to Kombisart, which contains the same doses of the components.
Before switching to a combination of fixed doses, it is recommended to individually select the dose for the components (that is, for amlodipine and valsartan). In case of clinical need, the possibility of direct replacement of monotherapy with a fixed dose combination can be considered.
The maximum daily dose of the preparation Kombisart is 2 tablets of 5 mg / 160 mg or 1 tablet of 10 mg / 160 mg (the maximum allowable doses of the components of the preparation are 10 mg for the content of amlodipine, 320 mg for the content of valsartan).
Impaired renal function. The preparation Kombisart is contraindicated in patients with severe renal impairment.
Patients with mild to moderate renal impairment do not require dose adjustment. In patients with moderate renal impairment, it is recommended to monitor the levels of potassium and creatinine in the blood.
The simultaneous use of the preparation Kombisart with aliskiren is contraindicated in patients with impaired renal function (glomerular filtration rate (GFR) 60 mg / min / 1.73 m2).
Diabetes. The simultaneous use of the preparation Kombisart with aliskiren is contraindicated in patients with diabetes mellitus.
Liver dysfunction. The preparationKombisart is contraindicated in patients with severely impaired liver function.
Kombisart should be used with caution in patients with impaired liver function or obstructive diseases of the biliary tract. Recommendations for dosing amlodipine in patients with mild to moderate hepatic impairment have not been developed.
Elderly patients (over 65 years old). For elderly patients, the usual dosage regimens are recommended.
Caution should be exercised when increasing the dose of the preparation in elderly patients.
Pediatric populations. The safety and efficacy of using the preparation Kombisart in children (under the age of 18) have not been studied. No data available.

Special instructions
Patients with sodium and / or bcc deficiency in the body. in patients with uncomplicated arterial hypertension (0.4%), excessive hypotension was noted. in patients with an activated renin-angiotensin system (races - with a reduced sodium content and / or volume and in the case of high-dose diuretics) who take angiotensin receptor blockers, symptomatic hypotension may occur. correction of this condition is recommended before using the preparation kombisart or careful medical supervision at the beginning of therapy.
If arterial hypotension occurs during the use of the preparation Kombisart, the patient should be placed on his back and, if necessary, given an intravenous infusion of a physiological solution. After stabilization of blood pressure, treatment can be continued.
Hyperkalemia. Care should be taken to concurrent treatment with potassium supplements, potassium-sparing diuretics, salt substitutes containing potassium, or other preparations that can increase potassium levels (heparin, etc.), and also provide for frequent monitoring of potassium content.
Renal artery stenosis. The preparation Kombisart should be used with caution for the treatment of hypertension in patients with unilateral or bilateral renal artery stenosis or stenosis of a single kidney, since serum urea and creatinine levels may increase.
Kidney transplant. There is no experience with the safe use of the preparation Kombisart in patients with recent kidney transplantation.
Liver dysfunction. Valsartan is excreted mainly unchanged in the bile. T1 / 2 of amlodipine is prolonged and the AUC is higher in patients with impaired liver function; dosage recommendations have not been established. Particular care is required when using the preparation Kombisart in patients with mild to moderate hepatic dysfunction or obstructive gallbladder disease.
Impaired renal function. Patients with mild to moderate renal impairment (GFR 30 ml / min / 1.73 m2) do not require dose adjustment. In moderate renal impairment, it is recommended to monitor the levels of potassium and creatinine in the blood.
The simultaneous use of ARBs, including valsartan, or an ACE inhibitor with aliskiren is contraindicated in patients with impaired renal function (GFR 60 mg / min / 1.73 m2).
Primary hyperaldosteronism. Patients with primary hyperaldosteronism should not take ARA II valsartan, since their RAS is impaired due to the underlying disease.
Angioedema. Quincke's edema, including edema of the larynx and glottis, which can lead to airway obstruction, and / or edema of the face, lips, pharynx and / or tongue have occurred in patients using valsartan. Some of these patients had a history of Quincke's edema while taking other preparations, including an ACE inhibitor. The use of the preparation Kombisart should be discontinued immediately if Quincke's edema occurs; reapplication is not recommended.
Heart failure / condition after myocardial infarction. Due to the inhibition of the renin-angiotensin-aldosterone system (RAAS) in sensitive patients, renal dysfunction is possible. In persons with severe heart failure, in whom renal function may depend on the activity of the RAAS, the use of ACE inhibitors and ARBs caused the development of oliguria and / or progressive azotemia, as well as (in rare cases) ARF and / or death. Similar results were noted with valsartan. Renal function should be assessed in patients with heart failure or after a history of myocardial infarction.
Calcium channel blockers, including amlodipine, should be used with caution in patients with congestive heart failure as they may increase the risk of cardiovascular events and death.
Stenosis of the aorta and mitral valve. As with treatment with other vasodilators, special care should be taken in patients who have mitral valve stenosis or severe mild aortic stenosis.
Double blockade of the RAAS. There is evidence that the combined use of an ACE inhibitor, ARB, or aliskiren increases the risk of arterial hypotension, hyperkalemia and decreased renal function (including ARF). Therefore, it is not recommended to carry out a double blockade of the RAAS by the combined use of an ACE inhibitor, ARA or aliskiren.
If double blockade is absolutely necessary, it should be carried out exclusively under the supervision of a specialist with frequent close monitoring of renal function, electrolyte concentration and blood pressure. Should not be used in combination with an ACE inhibitor and ARB in patients with diabetic nephropathy.
The use of the preparation Kombisart has not been studied in patients with diseases other than hypertension.
Use during pregnancy and lactation
Pregnancy. The preparation is contraindicated for pregnant women or women planning pregnancy. If pregnancy is confirmed during treatment with this preparation, its use should be stopped immediately and replaced with another preparation approved for use in pregnant women.
Data from epidemiological studies of the risk of teratogenicity after exposure to ACE inhibitors in the first trimester of pregnancy were not conclusive; however, a slight increase in risk cannot be ruled out. Although data from controlled epidemiological studies of ARA II are not available, a similar risk may arise with the use of preparations in this class.
The accumulation of ARA II in the II and III trimester is known to lead to toxic effects on the human fetus (decreased renal function, oligohydramnios, delayed ossification of the skull bones) and the newborn (renal failure, arterial hypotension, hyperkalemia).
If ARA II has been used since the second trimester of pregnancy, an ultrasound of the kidneys and fetal skull bones is recommended.
Infants whose mothers took ARAII should be closely monitored for the development of arterial hypotension.
Breastfeeding period. Since there is no information on the use of the preparation Kombisart during breastfeeding, the preparation is not recommended for use during breastfeeding; it is desirable to use alternative preparations with a studied safety profile, especially in the case of breastfeeding of newborns or premature babies.
Fertility Clinical studies of the effect on fertility have not been carried out.
Children. No study has been conducted on the treatment of children (under the age of 18) with this preparation. Therefore, until more complete information is obtained, Kombisart is not recommended for use in children.
The ability to influence the reaction rate when driving or working with other mechanisms. Patients using the preparation Kombisart may experience dizziness or a feeling of weakness after taking the preparation, so they should take this into account when driving and working with potentially dangerous mechanisms.
Amlodipine may slightly or moderately affect the ability to drive vehicles or work with other mechanisms. If patients experience dizziness, headache, fatigue or nausea while using amlodipine, their response may be impaired.
Interactions
Preparation-preparation interactions. studies of preparation-preparation interactions between kombisart and other preparations have not been carried out.
Medicines, the concomitant use of which requires care
Other antihypertensive preparations. Frequently used antihypertensive preparations (for example, blockers of α-adrenergic receptors, diuretics) and other preparations that can cause the appearance of undesirable antihypertensive effects (for example, tricyclic antidepressants, blockers of α-adrenergic receptors, used to treat benign prostatic hyperplasia), can enhance the antihypertensive effect of the combination ...
Interactions associated with amlodipine
Simultaneous use is not recommended
Grapefruit or grapefruit juice. The use of amlodipine with grapefruit juice or grapefruit is not recommended, since in some patients the bioavailability of the preparation may be increased, which will lead to an increase in the severity of the hypotensive effect.
Medicines that require care at the same time
Inhibitors of CYP 3A4. The simultaneous use of amlodipine with more or less potent inhibitors of CYP 3A4 (protease inhibitors, azole antifungal preparations, macrolides such as erythromycin or clarithromycin, verapamil or diltiazem) can lead to a significant increase in the systemic effect of amlodipine. The clinical manifestations of such pharmacokinetic changes may be exacerbated in elderly patients. Clinical monitoring and dose adjustment may be required.
CYP3A4 inducers (anticonvulsants (eg carbamazepine, phenobarbital, phenytoin, phosphenytoin, primidone), rifampicin, St. John's wort (Hypericum perforatum). There are no studies on the effect of CYP 3A4 inducers on amlodipine. Concomitant use of CYP3A4 inducers (eg rifampicin) may lead to a decrease in the concentration of amlodipine in the blood plasma.It is recommended to use amlodipine with caution with inducers of CYP 3A4.
Simvastatin. Repeated use of doses of 10 mg of amlodipine with 80 mg of simvastatin leads to an increase in the exposure of simvastatin by 77% compared with the use of simvastatin alone. It is recommended to reduce the daily dose of simvastatin to 20 mg for patients taking amlodipine.
Dantrolene (infusion). Due to the risk of hyperkalemia, it is recommended to avoid the combined use of calcium channel blockers, such as amlodipine, in patients prone to the development of malignant hyperthermia and in the treatment of malignant hyperthermia.
Medicines that require care at the same time
Other. Amlodipine did not affect the pharmacokinetics of atorvastatin, dioxin, warfarin, or cyclosporine.
Interactions associated with valsartan
Simultaneous use is not recommended
Lithium. With the simultaneous use of lithium with an ACE inhibitor or ARA II, including valsartan, a reversible increase in the concentration of lithium in the blood serum and its toxicity were noted. The simultaneous use of valsartan and lithium is not recommended. If the use of such a combination is necessary, the level of lithium in the blood serum should be carefully monitored. The risk of increased toxicity of lithium may be further increased when combined with Kombisart and diuretics.
Potassium supplements, potassium-sparing diuretics, salt substitutes containing potassium, or other medications that may increase potassium levels. If preparations that affect potassium channels are prescribed in combination with valsartan, regular monitoring of plasma potassium should be provided.
Medicines that require care at the same time
NSAIDs, including selective COX-2 inhibitors, acetylsalicylic acid (3 g / day) and non-selective NSAIDs. With the simultaneous use of ARA II and NSAIDs, it is possible to weaken the hypotensive effect. Also, the simultaneous use of ARA II and NSAIDs may increase the risk of impairment of renal function and serum potassium levels.
Therefore, at the beginning of treatment, it is recommended to monitor the state of kidney function, as well as ensure the proper level of fluid in the patient's body.
Inhibitors of the storage carrier (rifampicin, cyclosporine) or efflux carrier (ritonavir)
Valsartan is a substrate for the hepatic accumulation transporter OATP1B1 and the hepatic efflux transporter MRP2. The simultaneous use of inhibitors of the storage carrier (rifampicin, cyclosporine) or the efflux carrier (ritonavir) may increase the systemic exposure of valsartan.
Double blockade of RAAS with ARA, ACE inhibitors or aliskiren. Double blockade of the RAAS with the combined use of an ACE inhibitor, ARB or aliskiren leads to an increase in the incidence of such adverse events as hypotension, hyperkalemia and decreased renal function (including ARF), compared with treatment with a single preparation that affects the RAAS. Therefore, the simultaneous use of ARBs, including valsartan, or an ACE inhibitor with aliskiren is contraindicated in patients with diabetes mellitus or impaired renal function (GFR 60 mg / min / 1.73 m2).
Other. With valsartan monotherapy, clinically significant preparation interactions with such preparations have not been established: cimetidine, warfarin, furosemide, digoxin, atenolol, indomethacin, hydrochlorothiazide, amlodipine, glibenclamide.
Overdose
Symptoms to date, there is no experience of overdose of the preparation kombisart. the main symptom of an overdose of valsartan is probably severe arterial hypotension with dizziness. overdose of amlodipine can lead to increasing peripheral vasodilation and, probably, to reflex tachycardia. there is evidence of significant and potentially prolonged systemic hypotension, up to shock and death.
Treatment. If the preparation is recently taken, induce vomiting or gastric lavage. The absorption of amlodipine is significantly reduced when activated charcoal is used immediately or within 2 hours after taking amlodipine.
Clinically significant arterial hypotension caused by an overdose of the preparation Kombisart requires active support of the state of the cardiovascular system, including frequent monitoring of cardiac and respiratory functions, lifting the patient's lower limbs, attention to the volume of circulating fluid and urination. To restore vascular tone and blood pressure, a vasoconstrictor preparation can be used in the absence of contraindications to its use. With a persistent decrease in blood pressure, which is a consequence of calcium channel blockade, intravenous administration of calcium gluconate may be appropriate.
The elimination of valsartan and amlodipine by hemodialysis is unlikely.
Storage conditions
