Before starting treatment with the drug Korpil it is necessary to eliminate hyponatremia and hypovolemia. In patients who have been taking diuretics, it is necessary to cancel them, or at least reduce their dose 2-3 days before the start of the drug, Korpil (in this case, carefully monitor the condition of patients with chronic heart failure, due to the possibility of developing them decompensation due to increased volume of circulating blood).
After taking the first dose of the drug, as well as increasing its dose and / or dose of diuretics (especially "loop"), it is necessary to ensure careful medical supervision of the patient for at least 8 hours to promptly take appropriate measures in case of excessive blood pressure lowering.
If the drug is used for the first time or in high dose in patients with increased activity of RAAS, they should carefully monitor blood pressure, especially at the beginning of treatment, as these patients have an increased risk of excessive blood pressure lowering (see below).(See the Precautions section.)
With malignant arterial hypertension and heart failure in particular in the acute stage of myocardial infarction, drug treatment. Korpril should be started only in a hospital.
In patients with chronic heart failure, taking the drug may lead to a marked decrease in blood pressure, which in some cases is accompanied by oliguria or azotemia and rarely the development of acute renal failure. Caution should be exercised in the treatment of elderly patients, since they may be particularly sensitive to ACE inhibitors, it is recommended to monitor the initial phase of treatment. indicators of kidney function (see also section "Dosing and Administration").
In patients for whom a reduction in blood pressure may pose a certain risk (for example, in patients with atherosclerotic narrowing of the coronary or cerebral arteries) treatment should begin under strict medical supervision.
Care should be taken with physical activity and / or hot weather because of the risk of increased sweating and dehydration with the development of arterial hypotension, due to a decrease in the volume of circulating blood and a decrease in the concentration of sodium in blood.
During treatment with the drug, it is not recommended to drink alcohol.
Transient arterial hypotension is not a contraindication for continuing treatment after stabilizing blood pressure. In the case of repeated occurrence of severe arterial hypotension, the dose should be reduced or the drug should be withdrawn.
Patients treated with ACE inhibitors experienced cases of angioedema of the face, extremities, lips, tongue, pharynx or larynx. If there is swelling in the face (lips / eyelids) or tongue, or a violation of swallowing or breathing - the patient should immediately stop taking the drug. Angioedema, localized in the area of the tongue, pharynx / or larynx (possible symptoms: violation of swallowing or breathing) can be life threatening and requires urgent measures for its reduction: subcutaneous injection of 0.3-0.5 mg or intravenous drip injection of 0.1 mg epinephrine (adrenaline) (under the control of blood pressure, heart rate and ECG) following the use of glucocorticosteroids (iv / m / or inside), it is also recommended intravenous administration of antihistamines (antagonists H1 and H2-gistaminovyh receptors), and in case of insufficiency of enzyme inactivators C1-esterase can consider the need to introduce in addition to epinephrine enzyme inhibitors C1-esterase. The patient should be hospitalized and monitored until the symptoms come to a complete relief, but not less than 24 hours.
In patients receiving ACE inhibitors, there were cases of intestinal angioedema, which manifested itself with abdominal pain with or without nausea and vomiting; in some cases, angioedema has also been observed. When a patient appears on the background of treatment with ACE inhibitors of the above-described symptoms, the differential diagnosis should also consider the possibility of developing an intestinal angioedema.
Treatment aimed at desensitization to insect venom (bees, wasps) and simultaneous administration of ACE inhibitors can initiate anaphylactic and anaphylactoid reactions (eg, lowering blood pressure, dyspnea, vomiting, allergic skin reactions), which can sometimes be life threatening.Against the background of treatment with ACE inhibitors, hypersensitivity reactions to insect venom (eg, bees, wasps) develop more rapidly and take more severe course. If desensitization to insect venom is required, the ACE inhibitor should be temporarily replaced by a corresponding drug of another class.
With the use of ACE inhibitors, life-threatening, rapidly developing anaphylactoid reactions have been described, sometimes up to the development of shock during exercise. hemodialysis or plasma filtration using certain high-flow membranes (for example, polyacrylonitrile membranes), (see also manufacturers' instructions, membranes). It is necessary to avoid joint use of the drug Korpil and such membranes, for example, for urgent hemodialysis or hemofiltration. In this case, it is preferable to use other membranes or to exclude the use of ACE inhibitors. Similar reactions were observed in the apheresis of low-density lipoproteins using dextran sulfate. Therefore, this method should not be used in patients receiving ACE inhibitors.
In patients with impaired hepatic function, the response to treatment with Korpil may be either increased or decreased.In addition, in patients with cirrhosis of the liver with edema and / or ascites, significant activation of RAAS is possible, therefore, special care must be taken in the treatment of these patients (see also "Dosage and Administration").
Before surgery (including dental surgery), it is necessary to alert the surgeon / anesthesiologist about the use of ACE inhibitors.
It is recommended to closely monitor newborns who have been exposed to the intrauterine effect of ACE inhibitors for the detection of arterial hypotension, oliguria and hyperkalemia. In oliguria it is necessary to maintain blood pressure and renal perfusion by introducing appropriate fluids and vasoconstrictors .. In neonates, there is a risk of oliguria and neurological disorders, possibly due to a decrease in renal and cerebral blood flow due to a decrease in blood pressure caused by ACE inhibitors.
Control of laboratory parameters before and during treatment with the drug Korpil (up to 1 time per month in the first 3-6 months of treatment)
Control of kidney function (determination of serum creatinine concentrations)
In the treatment of ACE inhibitors in the first weeks of treatment of willows.later, it is recommended to monitor kidney function. Particularly careful monitoring is required for patients with acute and chronic heart failure, renal dysfunction, kidney transplantation, patients with renovascular disease, including patients with hemodynamically significant unilateral renal artery stenosis in the presence of two kidneys (in such patients, even a slight increase in serum creatinine concentration may be an index of decreased renal function).
Controlling the concentration of electrolytes
Regular monitoring of the potassium concentration in the blood serum is recommended. Especially regular monitoring of potassium concentration in blood serum is required for patients with impaired renal function, significant violations of water-electrolyte balance, chronic heart failure.
Control of hematological parameters (hemoglobin, leukocytes, erythrocytes, platelets, leukocyte formula)
It is recommended to monitor the parameters of the general blood test, to identify possible leukopenia. More regular monitoring is recommended at the beginning of treatment and in patients with impaired renal function,as well as in patients with connective tissue diseases or in patients receiving concomitantly other drugs capable of altering the pattern of peripheral blood (see section "Interaction with Other Drugs"). Controlling the number of leukocytes is necessary for the early detection of leukopenia, which is especially important in patients with an increased risk of developing it, and also at the first signs of infection. If neutropenia is detected (the number of neutrophils is less than 2000 / μL), treatment with ACE inhibitors should be discontinued.
When symptoms appear due to leukopenia (eg, fever, enlargement of lymph nodes, tonsillitis), urgent monitoring of the picture of peripheral blood is needed. In case of signs of bleeding (the smallest petechiae, red-brown rashes on the skin and mucous membranes), it is also necessary to control the number of platelets in the peripheral blood.
Determination of the activity of "liver" enzymes, the concentration of bilirubin in the blood
When jaundice or significant increase in the activity of "liver" enzymes, treatment with Korpil should be stopped and medical supervision of the patient should be provided.
