Patients with prior diuretic therapy
It is necessary, if possible, to cancel diuretics for 2-3 days (depending on the duration of the action of diuretics) before starting treatment with the drug DILAPREL® PLUS, or at least reduce the dose of diuretics taken. Treatment of such patients should start with taking 1 capsule with a dosage of 0.625 mg + 2.5 mg once a day in the morning. After taking the first dose and after increasing the dose of DILAPREL® PLUS, patients should be under medical supervision for at least 8 hours to avoid an uncontrolled hypotensive reaction.
Ischemic heart disease and cerebral circulatory insufficiency The risk of arterial hypotension exists in all patients, but in patients with ischemic heart disease and cerebral circulatory insufficiency, special care should be taken in the treatment with the drug DILAPREL® PLUS. Treatment should begin with a daily dose of 0.625 mg + 2.5 mg (initial dose).
Impaired renal function
Therapy with the drug DILAPREL® PLUS is contraindicated in patients with severe renal insufficiency (KC less than 30 ml / min).In some patients with hypertension without a previous impairment of kidney function, the appearance of symptoms of acute renal failure may occur with DILAPREL® PLUS therapy. In this case, the treatment with the drug DILAPREL® PLUS should be discontinued. In the future, it is possible to resume combination therapy, using low doses of the drug DILAPREL® PLUS, or to use indapamide and ramipril in monotherapy. Such patients need regular monitoring of the potassium content and creatinine concentration in the blood plasma every 2 weeks after the start of therapy and every subsequent 2 months of therapy with the drug DILAPREL® PLUS.
Acute renal failure often develops in patients with severe chronic heart failure or initial renal impairment, including bilateral renal artery stenosis or arterial stenosis of a single functioning kidney. The use of the drug DILAPREL® PLUS is contraindicated in patients with bilateral stenosis of the renal arteries or stenosis of the artery of a single functioning kidney.
Arterial hypotension and disturbance of water-electrolyte balance
Before starting treatment with the drug DILAPREL PLUS, it is necessary to eliminate hyponatremia and hypovolemia. Hyponatremia is associated with a risk of a sudden drop in blood pressure (especially in patients with bilateral stenosis of the renal arteries or stenosis of the artery of a single functioning kidney). Therefore, when observing patients dynamically, attention should be paid to possible symptoms of dehydration and a decrease in the electrolyte content in the blood plasma, for example, after prolonged diarrhea or vomiting. Such patients need regular monitoring of the content of plasma electrolytes. With a marked decrease in blood pressure, an intravenous injection of 0.9% sodium chloride solution may be required.
Transient arterial hypotension is not a contraindication for continuing therapy. After the recovery of bcc and blood pressure, it is possible to resume therapy with the drug DILAPREL® PLUS, using low doses of the drug, or use the drugs indapamide and ramipril in monotherapy.
The content of potassium
The combined use of indapamide and ramipril may lead to the development of hypokalemia, especially in patients with diabetes mellitus or renal insufficiency.Against the background of taking the drug DILAPREL® PLUS, it is necessary to regularly monitor the potassium content in the blood plasma. Patients with hypokalemia use of the drug DILAPREL® PLUS is contraindicated.
Excipients
It should be noted that the composition of excipients of the drug DILAPREL® PLUS includes lactose monohydrate. The use of the drug DILAPREL® PLUS is contraindicated in patients with lactose intolerance, lactase deficiency, glucose-galactose malabsorption.
Indapamide
Dysfunction of the liver
With the use of thiazide and thiazide-like diuretics in patients with impaired hepatic function, it is possible to develop hepatic encephalopathy, especially in the case of disturbance of the water-electrolyte balance. In this case, you should immediately stop taking DILAPREL® PLUS.
Photosensitivity
Against the background of taking thiazide and thiazide-like diuretics, cases of development of photosensitivity reactions were reported. In the case of developing photosensitivity reactions against the background of the drug DILAPREL® PLUS should stop treatment. If it is necessary to continue therapy with the drug DILAPREL® PLUS, it is recommended to protect open skin areasfrom direct exposure to solar and artificial ultraviolet rays.
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 figure. All diuretics can cause hyponatremia, which sometimes leads to extremely serious consequences. It is necessary to regularly monitor the sodium content, since initially a decrease in the sodium content in the blood plasma may not be accompanied by the appearance of pathological symptoms. The most careful control of the sodium content is indicated for patients with cirrhosis of the liver and elderly patients.
The content of potassium in blood plasma
Therapy with thiazide and thiazide-like diuretics is associated with a risk of hypokalemia (the level of potassium in the blood plasma is below 3.4 mmol / l) in patients of the following categories: elderly patients who are weakened or are receiving concomitant drug therapy with other antiarrhythmic drugs and drugs that may increase the interval QT, patients with cirrhosis of the liver, peripheral edema or ascites, IHD, heart failure.Hypokalemia in such patients increases the toxic effect of cardiac glycosides and increases the risk of arrhythmias.
In addition, the high-risk group includes patients with an increased interval QT on the ECG, it does not matter whether this increase is due to innate causes or effects of drugs.
Hypokalemia, as well as bradycardia, is a condition conducive to the development of severe arrhythmias and, especially, pirouette-type arrhythmias, which can lead to death. In all the cases described above, it is necessary to regularly monitor the potassium content in the blood plasma. The first measurement of the potassium content in the blood plasma should be performed during the first week after the start of therapy with the drug DILAPREL® PLUS.
If hypokalemia is detected, appropriate treatment should be prescribed.
Calcium in the blood plasma
Thiazide and thiazide-like diuretics reduce the excretion of calcium by the kidneys, leading to a slight and temporary increase in the calcium content in the blood plasma. Expressed hypercalcemia may be a consequence of latent hyperparathyroidism.DILAPREL® PLUS should be withdrawn before the function of parathyroid glands is examined.
The concentration of glucose in the blood plasma
It is necessary to monitor the concentration of glucose in blood plasma in patients with diabetes mellitus, especially in the presence of hypokalemia.
Uric acid
In patients with a high concentration of uric acid in the blood plasma does not increase the risk of gout. Patients with gout may increase the incidence of attacks or exacerbate the course of gout.
Diuretic drugs and kidney function
Thiazide and thiazide-like diuretics are effective only in patients with normal or slightly impaired renal function (plasma creatinine in adults below 25 mg / L or 220 μmol / L). In elderly patients, the normal concentration of creatinine in the blood plasma is calculated taking into account age, body weight and sex.
It should be borne in mind that at the beginning of treatment, patients may experience a decrease in the glomerular filtration rate due to hypovolemia, which in turn is caused by loss of fluid and sodium ions on the background of taking diuretic drugs.As a consequence, the blood plasma can increase the concentration of urea and creatinine. If the function of the kidneys is not impaired, such temporary functional renal failure usually passes without consequences, but with the existing renal failure, the patient's condition may worsen.
Athletes
Indapamide can give a positive result in the conduct of doping control.
Ramipril
Neutropenia / agranulocytosis
In patients taking ACE inhibitors, there may be cases of development of neutropenia / agranulocytosis. The risk of developing neutropenia is dose-dependent and depends on the drug taken and the presence of concomitant diseases. In patients with normal renal function, in the absence of other complications, neutropenia develops rarely and passes on its own after the withdrawal of ACE inhibitors. Particular care should be taken in patients with systemic connective tissue diseases (including systemic lupus erythematosus, scleroderma), as well as with immunosuppressant therapy, allopurinol or procainamide, especially with existing renal dysfunction.Such patients may develop a severe infection that does not respond to intensive antibiotic therapy. It is recommended to periodically monitor the number of leukocytes in the blood. The patient should be warned that in case of any signs of an infectious disease (sore throat, fever), you should immediately consult a doctor.
Angioedema (edema of Quincke)
In rare cases, angiotoneurotic edema of the face, extremities, lips, tongue, upper ligament, pharynx and / or larynx can develop on the background of therapy with ACE inhibitors. If these symptoms appear, stop taking DILAPREL® PLUS immediately. It is necessary to monitor the patient's condition until the signs of edema disappear completely. If the swelling affects only the face and lips, then its manifestations usually go without special treatment, but for faster relief of symptoms, you can use antihistamines. Angioedema, accompanied by edema of the pharynx and / or larynx, can lead to airway obstruction and death. In this case, you should immediately enter epinephrine (epinephrine) subcutaneously at a dose of 1: 1000 (0.3 to 0.5 ml) and / or provide airway patency. In the future, such patients should not use ACE inhibitors. Patients with a history of Quincke edema who are not associated with taking ACE inhibitors may be at increased risk for developing Quincke's edema when taking this group's medications.
In rare cases against the background of therapy with ACE inhibitors, intestinal angioedema develops. In this case, patients have 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 is established using computed tomography of the abdominal cavity, ultrasound, or at the time of surgery. Symptoms disappear after stopping the intake of ACE inhibitors. In patients with abdominal pain receiving ACE inhibitors, the differential diagnosis should take into account the possibility of developing an intestinal angioedema.
Anaphylactoid reactions during desensitization
There are separate reports on the development of long-life-threatening anaphylactoid reactions in patients receiving ACE inhibitors during desensitizing therapy with the poison of Hymenoptera insects (bees, wasps). ACE inhibitors should be used with caution in patients prone to allergic reactions undergoing desensitization procedures. ACE inhibitors are contraindicated in patients receiving desensitizing therapy with venom of Hymenoptera insects, such as bees, wasps. The development of anaphylactoid reactions can be avoided by the temporary withdrawal of the ACE inhibitor at least 24 hours before the desensitization procedure begins.
Anaphylactoid reactions during apheresis LDL
In rare cases, patients receiving ACE inhibitors may develop life-threatening anaphylactoid reactions in LDL-apheresis with dextran sulfate. To prevent the anaphylactoid reaction, ACE inhibitor therapy should be discontinued before each procedure for LDL apheresis using dextran sulfate.
Anaphylactoid reactions during hemodialysis
In patients receiving ACE inhibitors, during hemodilysis with the use of high-flow membranes, anaphylactoid reactions were noted. Therefore, it is necessary to use a different type of membrane or to use an antihypertensive drug of another pharmacotherapeutic group.
Cough
Against the background of therapy with an ACE inhibitor, it is possible to develop a dry persistent cough, which disappears after the withdrawal of drugs of this group. When a dry cough occurs in a patient, one should keep in mind the possible connection of this symptom with the administration of an ACE inhibitor. If the doctor believes that therapy with an ACE inhibitor is necessary for the patient, the use of the drug DILAPREL® PLUS can be continued.
Risk of arterial hypotension and / or renal failure
In some pathological states, a significant activation of RAAS can occur, especially with severe hypovolemia and a decrease in the content of plasma electrolytes (against a background of a salt-free diet or long-term diuretics), in patients with initially low blood pressure, bilateral stenosis of the renal arteries or with stenosis of the artery of a single kidney, chronic heart failure or cirrhosis of the liver with edema and ascites.The use of an ACE inhibitor causes blockade of RAAS and therefore may be accompanied by a sharp decrease in blood pressure and / or an increase in plasma creatinine concentration, which indicates the development of acute renal failure. These phenomena are more often observed with the first dose of ramipril or during the first two weeks of therapy. Sometimes these conditions develop rapidly in other periods of therapy. In such cases, when the therapy is resumed, it is recommended to use the drug DILAPREL® PLUS in a lower dose and then gradually increase the dose.
Diabetes
When using the drug DILAPREL® PLUS in patients with diabetes mellitus, receiving hypoglycemic agents for oral administration or insulin, during the first month of therapy, it is necessary to regularly monitor the concentration of glucose in the blood.
Renovascular hypertension
The use of ACE inhibitors has a beneficial effect in patients with renovascular hypertension, both awaiting surgery and when surgery is not possible. Treatment with DILAPREL® PLUS should be started with a low dose of the drug in a hospital setting, controlling the kidney function and the potassium content in the blood plasma.Some patients may develop functional kidney failure, which quickly disappears when the drug is withdrawn.
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, which have an antihypertensive effect. It is recommended to stop taking ACE inhibitors 48 hours before surgery, warning the anesthesia doctor about the use of ACE inhibitors.
Anemia
Anemia can develop in patients who have undergone kidney transplantation, or in patients on hemodialysis. At the same time, the decrease in hemoglobin concentration is greater, the higher its initial concentration was. This effect, apparently, is not dose-dependent, but may be related to the mechanism of action of ACE inhibitors. A slight decrease in hemoglobin concentration occurs during the first 6 months of treatment, then the hemoglobin concentration remains stable and completely restored after the drug is discontinued.In such patients, treatment can be continued, but a general blood test should be carried out regularly.
Aortic stenosis / mitral stenosis / Hypertrophic obstructive cardiomyopathy
ACE inhibitors are contraindicated in patients with obstruction of the left ventricular outflow tract and with aortic and / or mitral stenosis and GOKMP.
Liver failure
In rare cases, with the administration of ACE inhibitors, cholestatic jaundice occurs, with the progression of which rapid development of fulminant liver necrosis, sometimes fatal, is possible. When jaundice or a significant increase in the activity of "liver" transaminases on the background of the administration of ACE inhibitors, the patient should stop taking the drug DILAPREL® PLUS.
Hyperkalemia
During treatment with ACE inhibitors, hyperkalemia may develop. Risk factors for hyperkalemia are renal failure, elderly age, diabetes mellitus, some concomitant conditions (decreased BCC, acute heart failure in decompensation, metabolic acidosis), simultaneous intake of potassium-sparing diuretics (such as spironolactone, eplerenone, triamterene, amiloride), as well as preparations of potassium or potassium-containing substitutes for edible salt and the use of other drugs that increase the level of potassium in the blood plasma (for example, heparin). Hyperkalemia can lead to serious heart rhythm disturbances, sometimes with a fatal outcome. Simultaneous use of the above drugs is contraindicated.
Other risk groups
In patients with chronic heart failure (IV functional class by classification NYHA) and patients with type 1 diabetes mellitus (the risk of spontaneous increase in potassium content) treatment should be started with low doses of the drug DILAPREL® PLUS and carried out under the constant supervision of a doctor.
In patients with hypertension and coronary artery disease, beta-blockers should not be discontinued: ACE inhibitors should be used together with beta-blockers.
Elderly patients
In elderly patients, before starting the drug DILAPREL® PLUS, it is necessary to evaluate the function of the kidneys and the content of potassium in the blood plasma. In order to prevent the development of arterial hypotension, a consistent correction of the initial dose of the drug is carried out in accordance with the indices of blood pressure, especially with a decrease in the bcc.
Ethnic differences
ACE inhibitors have a less pronounced antihypertensive effect in patients of the Negroid race compared with representatives of other races.
