Ko-Dalnev®
Impaired renal function
The preparation of Co-Dalnev is contraindicated in patients with SC less than 60 ml / min.
In some patients with AH without previous obvious impairment of renal function against the background of therapy, laboratory signs of functional renal failure may appear. In this case, the drug should be discontinued. AT further it is possible to renew the combined therapy, using low doses of the combination of perindopril and indapamide, or apply these drugs separately. Such patients need regular monitoring of potassium content and serum creatinine concentration 2 weeks after the start of therapy and then every 2 months.
The development of renal insufficiency often occurs in patients with severe CHF or an initial impairment of kidney function, including with stenosis of the renal artery. The drug ns is recommended for patients with bilateral stenosis of the renal artery or stenosis of the artery of a single functioning kidney.
Arterial hypotension and disturbance of water-electrolyte balance
In patients with hyponatremia (especially with renal artery stenosis, including bilateral), there is a risk of sudden development of arterial hypotension.Therefore, attention should be paid to the possible symptoms of dehydration and a decrease in the electrolyte content in the blood plasma, for example, after diarrhea or vomiting. The use of ACE inhibitors causes blockade of RAAS and therefore may be accompanied by a sharp decrease in blood pressure and / or an increase in the concentration of creatinine in the blood plasma, which indicates the development of functional renal failure. These phenomena are more often observed when taking the first dose of the drug or during the first two weeks of therapy and sometimes develop acutely. Such patients need regular monitoring of the content of plasma electrolytes. In severe arterial hypotension, intravenous administration of 0.9% sodium chloride solution may be required. Transient arterial hypotension is not a contraindication for the continuation of therapy. After recovery of circulating blood volume (BCC) and blood pressure, treatment can be resumed using low doses of perindopril and indapamide, or applied separately.
Elderly patients
Before starting the preparation of Ko-Dalnev® it is necessary to evaluate the functional activity of the kidneys and the content of potassium in the blood plasma.At the beginning of therapy, the dose of the drug is selected, taking into account the degree of BP reduction, especially in case of a decrease in BCC and loss of electrolytes, which allows to avoid a sharp decrease in blood pressure.
Atherosclerosis
The risk of developing arterial hypotension exists in all patients, but special care should be taken in patients with ischemic heart disease (INS) and cerebrovascular disease. In such patients, treatment starts with low doses preparation.
Amlodipine
CHF
In patients with CHF (III and IV functional class classification NYHA) treatment is carried out with caution, in connection with the possibility of developing pulmonary edema. BCCI, including amlodipine, should be used with caution in patients with CHF, due to the possible increase in the risk of development of adverse events from the cardiovascular system and mortality.
Impaired liver function
In patients with a violation of liver function T1 / 2 and AUC Amlodipine increases. Admission of amlodipine should be started with the lowest doses and caution both at the beginning of therapy and with increasing doses of amlodipine. Patients with severe dysfunction of the liver should be gradually increased the dose, careful monitoring of the clinical condition is necessary.
Indapamide
In the presence of a violation of liver function, the use of thiazide and thiazide-like diuretics can lead to the development of hepatic encephalopathy. In this case, stop taking the medication immediately.
Photosensitivity
Against the background of taking thiazide and thiazide-like diuretics, cases of the development of the photosensitivity reaction were reported. If the photosensitivity reaction develops, discontinue treatment. If it is necessary to continue therapy with diuretics, it is recommended to protect the skin from exposure to sunlight or artificial ultraviolet rays.
Water-electrolyte balance
The content of sodium in the blood plasma
Before the start of treatment it is necessary to determine the sodium content in the blood plasma. Against the background of taking the drug should regularly monitor this indicator. All diuretics are capable of causing hyponatraemia, which sometimes leads to serious complications. At the initial stage of therapy, a decrease in the sodium level in the blood plasma can be asymptomatic, so regular laboratory monitoring is necessary. Older patients are shown more frequent control of sodium in the blood plasma.
The content of potassium in blood plasma
Therapy with thiazide and thiazide-like diuretics is associated with a risk of hypokalemia. It is necessary to avoid hypokalemia (less than 3.4 mmol / L) in the following categories of patients from high-risk groups: elderly patients, patients, patients with cirrhosis of the liver, including with edema and ascites, patients with IHD, CHF. In such patients, hypokalemia increases the toxic effect of cardiac glycosides and increases the risk of arrhythmia.
The high-risk group also includes patients with an elongated interval QT, as hereditary, hack and caused by medicinal action. Hypokalemia, like bradycardia, contributes to the development of severe cardiac arrhythmias, especially polymorphic ventricular pirouette tachycardia, which can lead to death. In all the cases described above, regular monitoring of the potassium content in the blood plasma is necessary. It is necessary to determine the content of potassium in the blood plasma during the first week after the initiation of therapy. If hypokalemia is detected, appropriate therapy should be performed.
Calcium in the blood plasma
Thiazide and thiazide-like diuretics reduce the excretion of calcium by the kidneys, which can cause a slight temporary increase in calcium in the blood plasma. Expressed hypercalcemia may be associated with previously undiagnosed hyperparathyroidism. In such cases, it is necessary to conduct a study of the function of the parathyroid glands, having previously canceled the administration of diuretics.
Uric acid
In patients with elevated uric acid concentrations in blood plasma, the frequency of gout attacks may increase with therapy.
Impaired renal function
Thiazide and thiazide-like diuretics are fully effective only in patients with normal or slightly impaired function of the nights (plasma creatinine concentration in adult patients is below 25 mg / L or 220 μmol / L). In elderly patients, CC is calculated taking into account age, body weight and sex.
In patients with hypovolemia and hyponatremia, early treatment with diuretics may result in a temporary decrease in glomerular filtration rate and an increase in the concentration of urea and creatinine in the blood plasma.This transient functional renal failure is not dangerous for patients with unchanged renal function, however, in patients with renal insufficiency, its severity can be increased.
These patients should regularly monitor the potassium content and creatinine concentration in the blood plasma.
Athletes
Indapamide can give a positive reaction during doping control.
Perindopril
Neutropenia / agranulocytosis
Against the background of the administration of ACE inhibitors, neutropenia / agranulocytosis, thrombocytopenia and anemia can occur. In patients with normal renal function, in the absence of other risk factors, neutropenia develops rarely. After the abolition of the ACE inhibitor, neutropenia and agranulocytosis pass independently. With extreme caution should be applied perindopril in patients with systemic connective tissue diseases on the background of therapy with immunosuppressants, allopurinol or procainamide, especially in patients with impaired renal function. Some patients developed severe infections, in some cases resistant to intensive antibiotic therapy.When using perindopril in these patients it is recommended to periodically monitor the number of leukocytes in the blood plasma. If any symptoms of infectious diseases (eg, sore throat, fever) appear, patients should consult a doctor.
Hypersensitivity / angioedema
Against the background of taking ACE inhibitors, including perindopril, in rare cases development of angioedema of the face, limbs, lips, tongue, vocal cords and / or larynx can be observed. If symptoms appear, stop taking the medication immediately and continue monitoring the patient until the symptom is completely relieved. Typically, the edema of the face and lips treatment ns requires, although for relief of symptoms can be used antihistamines. Angioedema, accompanied by swelling of the larynx, can lead to death. Swelling of the tongue, vocal cords, or larynx can lead to airway obstruction. If such symptoms occur, immediately inject epinephrine (adrenaline) solution in a 1: 1000 dilution (0.3-0.5 ml) subcutaneously and / or provide airway patency.In patients with angioedema, a history that is not associated with the administration of ACE inhibitors. the risk of developing it may be increased when taking medications of this group.
In rare cases, against the background of therapy with ACE inhibitors, angioedema develops in the intestine. In this case, patients have complaints of abdominal pain as an isolated symptom or in combination with nausea and vomiting, in some cases without a previous angioedema and at a normal level of C-1 esterase. The diagnosis was established using computed tomography, ultrasound examination of the abdominal cavity organs, or during surgical intervention. Symptoms disappear after stopping the intake of ACE inhibitors. Therefore, patients with complaints of pain in the abdominal area, taking inhibitors ACE, in the conduct of differential diagnosis should take into account the possibility of angioedema edema of the intestine.
Anaphylactoid reactions during desensitization
There are some reports of the development of anaphylactoid reactions in patients taking AIF inhibitors during desensitizing therapy (for example, the venom of Hymenoptera insects: bees, wasps).The development of such reactions was avoided by the temporary withdrawal of ACE inhibitors (no less than 24 hours before desensitization), with the occasional administration of an ACE inhibitor anaphylactoid reaction appeared again.
Anaphylactoid reactions during apheresis LDL
In rare cases in patients receiving ACE inhibitors, in the conduct of LDL-apheresis using dextran sulfate may develop life threatening anaphylactoid reactions. To prevent such reactions, you should temporarily stop taking ACE inhibitors before each apheresis procedure.
Hemodialysis
In rare cases in patients receiving ACE inhibitors, hemodialysis using high-permeability membranes (for example, AN69®) anaphylactoid reactions developed. Therefore, it is recommended to use a different type of membrane or use an antihypertensive drug of another pharmacotherapeutic group.
Cough
Against the background of therapy with ACE inhibitors, dry cough may occur. Cough persists for a long time against the background of taking this group's drugs and disappears after their withdrawal. When a patient has a dry cough, remember the possibility of his appearance in connection with the receptionan ACE inhibitor. If it is necessary to use drugs of this group, the ACE inhibitor may be continued.
Aortic and mitral stenosis, GOKMP
ACE inhibitors should be used with caution in patients with obstruction of the left ventricular outflow tract and in mitral stenosis.
Diabetes
In patients with diabetes mellitus receiving hypoglycemic agents for ingestion or insulin, during the first month of treatment with an ACE inhibitor, regular monitoring of the glucose concentration in the blood plasma is necessary.
Surgery / general anesthesia
The use of ACE inhibitors in patients undergoing surgery with general anesthesia can lead to a marked decrease in blood pressure, especially with the use of general anesthetics with an antihypertensive effect. It is recommended to stop the use of long-acting inhibitors, including perindopril, 24 hours before surgery.
Ethnic differences
In patients of the Negroid race more often than in the representatives of other races, against the background of the use of ACE inhibitors, angioedema develops. Perindopril, as well as other ACE inhibitors, obviously has a less pronounced antihypertensive effect in patients of the Negroid race compared with representatives of other races. Perhaps this difference is due to the fact that patients with arterial hypertension of the Negroid race are more likely to have low renin plasma activity.
Liver failure
In rare cases, when taking ACE inhibitors, cholestatic jaundice occurs. With the progression of this syndrome, fulminant liver necrosis develops, sometimes with a fatal outcome. The mechanism of development of this syndrome is unclear. With a significant increase in the activity of "hepatic" enzymes or the appearance of jaundice when taking ACE inhibitors should stop taking the drug and continue to monitor the patient.
Hyperkalemia
Against the background of taking ACE inhibitors, hyperkalemia may develop. Risk factors for hyperkalemia is renal failure, advanced age (over 70 years), diabetes mellitus, some comorbid conditions (dehydration, acute decompensation of chronic heart failure, metabolic acidosis), concomitant use of potassium-sparing diuretics (spironolactone, eplerenone, triamterene, amiloride), potassium preparations, potassium-containing substitutes for edible salt, and other agents that promote potassium levels in the blood plasma (eg, heparin) (especially in patients with reduced function of the nights). Hyperkalemia can lead to serious, sometimes fatal heart rhythm disturbances. If it is necessary to use the drug simultaneously with the above-mentioned drugs, you should be careful and regularly monitor the potassium content in the blood plasma.
Renovascular hypertension
The method of treating reninvascular hypertension is revascularization. Nevertheless, the use of ACE inhibitors can be effective in patients with renovascular hypertension, both waiting for surgery and when it is not possible.
In patients with diagnosed or suspected renal artery stenosis treatment should begin with lower doses of the drug Ko-Dalnev®. Some patients may develop functional kidney failure, which occurs after the drug is discontinued.
