The drug Indapamide / Perindopril-Teva
Preparations lithiI
It is not recommended simultaneous use of the drug Indapamide / Perindopril-Teva with lithium preparations.
Impaired renal function
Indapamide / Perindopril-Teva therapy is contraindicated in patients with severe renal insufficiency (CC less than 30 ml / min). In some patients with hypertension without a previous impairment of kidney function, Indapamide / Perindopril-Teva may show signs of acute renal failure. In this case, treatment with Indapamide / Perindopril-Teva should be discontinued.In the future, you can resume therapy, using either low doses of the drug Indapamide / Perindopril-Teva, or drugs perindopril and indapamide in monotherapy. In these patients, it is necessary to carry out regular monitoring of potassium and creatinine serum concentration 2 weeks after initiation of therapy and then every 2 months following therapy with Indapamide / Perindopril-Teva.
Acute renal failure often develops in patients with severe CHF or an initial impairment of kidney function, incl. with bilateral stenosis of the renal arteries or stenosis of the artery of a single functioning kidney.
The drug Indapamide / Perindopril-Teva is usually not recommended in case of bilateral renal artery stenosis or stenosis of the artery only functioning kidney.
Reduction of blood pressure and violation of water-electrolyte balance
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 the possible symptoms of dehydration and a decrease in the electrolyte content in the blood plasma, for example, after prolonged diarrhea or vomiting.In such patients it is necessary to regularly monitor the content of electrolytes in the blood plasma. With a marked decrease in blood pressure, you may need to / in the introduction of 0.9% solution of sodium chloride.
Transient arterial hypotension is not a contraindication for further continuation of therapy. After the recovery of bcc and blood pressure, it is possible to resume therapy with Indapamide / Perindopril-Teva using either low-dose drugs or perindopril and indapamide in monotherapy.
The content of potassium
The use of Indapamide / Perindopril-Teva does not prevent the development of hypokalemia, especially in patients with diabetes mellitus or renal insufficiency. Regularly monitor the potassium content in the blood plasma.
Excipients
It should be borne in mind that at Ingredients of the preparation Indapamide / Perindopril-Teva include lactose monohydrate, therefore the drug is contraindicated in patients with hereditary lactose intolerance, lactase deficiency, glucose-galactose malabsorption.
Perindopril
Neutropenia / agranulocytosis
In patients taking ACE inhibitors, there may be cases of development of neutropenia / agranulocytosis, thrombocytopenia and anemia.In patients with normal renal function and the absence of other complications, neutropenia develops rarely and passes on its own after the withdrawal of ACE inhibitors.
Perindopril should be used with caution in patients with connective tissue disease and simultaneously receiving immunosuppressive therapy, allopurinol or procainamide, especially with existing impairments of kidney function. Such patients can develop severe infections that are not amenable to intensive antibiotic therapy. In the case of perindopril it is recommended to periodically monitor the amount of white blood cells in the blood. The patient should be warned that at If there are any signs of an infectious-inflammatory disease (sore throat, fever), you should immediately consult a doctor.
Angioedema (edema of Quincke)
When taking ACE inhibitors, including perindopril, in rare cases, development of an angioedema of the face, lips, tongue, tongue of the upper palate and / or larynx can be observed. If these symptoms appear, the drug should be stopped immediately, the patient should be observed until the signs of edema disappear completely.
If the angioedema has spread only to the face and lips, then its manifestations usually pass independently, or antihistamines may be used to treat its symptoms. Angioedema, accompanied by swelling of the tongue or larynx, can lead to airway obstruction and death.
Patients with a history of Quincke's edema who are not associated with the administration of ACE inhibitors may be at increased risk of developing it with this group of drugs.
In rare cases, against the background of therapy with ACE inhibitors, angioedema develops in the intestine. In this case, patients have abdominal pain as an isolated symptom or are accompanied by nausea and vomiting, in some cases without a previous angioedema and with normal activity C1-esterase. The diagnosis is established by means of computed tomography of the abdominal cavity, ultrasound examination or at the time of surgical intervention. Symptoms disappear after stopping the intake of ACE inhibitors. In patients with abdominal pain receiving ACE inhibitors, a differential diagnosis should take into accountthe possibility of angioedema edema development of the intestine.
Anaphylactoid reactions during desensitization procedures
There are separate reports on the development of long-term, life-threatening anaphylactoid reactions in patients receiving ACE inhibitors during desensitizing therapy with Hepaticoptera insects (bees, wasps). The use of ACE inhibitors should be avoided in patients receiving immunotherapy with venom of Hymenoptera. 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 of LDL
In rare cases, patients receiving ACE inhibitors may experience life-threatening anaphylactoid reactions during LDL-apheresis with dextrin sulfate. To prevent the anaphylactoid reaction, ACE inhibitor therapy should be discontinued before each procedure for LDL apheresis using high-flow membranes.
Hemodialysis
In patients receiving ACE inhibitors, hemodialysis using high-flow membranes (for example,AN69®), anaphylactoid reactions were noted. Therefore, it is desirable to use a different type of membrane or to use an antihypertensive drug of another pharmacotherapeutic group.
Potassium-sparing diuretics and potassium preparations
Simultaneous use of perindopril and potassium-sparing diuretics, as well as preparations of potassium and potassium-containing substitutes for edible salt is not recommended.
Cough
Against the background of therapy with an ACE inhibitor, a dry cough may occur, which disappears after the withdrawal of this group. When dry cough occurs, remember the possible association of this symptom with the administration of an ACE inhibitor. If the doctor believes that ACE inhibitor therapy is necessary for the patient, taking Indapamide / Perindopril-Teva may be continued.
Age under 18 years old
The drug Indapamide / Perindopril-Teva is contraindicated in children under 18 years due to lack of data on efficacy and safety of use.
The risk of arterial hypotension and / or renal failure in patients with heart failure, a violation of the water-electrolyte balance, etc.
With cirrhosis of the liver, accompanied by edema and ascites, arterial hypotension, CHF,Significant activation of the renin-angiotensin-aldosterone system (RAAS) can be noted, especially with severe hypovolemia and a decrease in the electrolyte content in the blood plasma (against a background of a salt-free diet or a long-term intake of diuretics).
The use of an ACE inhibitor can cause blockade of the RAAS, in this connection, a sharp decrease in blood pressure and / or an increase in plasma creatinine concentration, indicating the development of acute renal failure, is more likely to occur with the first dose of Indapamide / Perindopril-Teva or during the first 2 weeks of therapy.
Elderly patients
Before starting the drug, Indapamide / Perindopril-Teva should be evaluated by the kidney function and the potassium content in the blood plasma. The initial dose of the drug Indapamide / Perindopril-Teva is selected depending on the degree of BP reduction, especially with a decrease in bcc and CHF (IV functional class by classification NYHA). Such measures allow to avoid a sharp decrease in blood pressure,
Atherosclerosis
The risk of arterial hypotension exists in all patients, but special care should be taken when using Indapamide / Perindopril-Teva in patients with coronary artery disease and cerebral circulatory insufficiency.In such patients, treatment should begin with the recommended initial dose of Indapamide / Perindopril-Teva.
Patients with Renovascular Hypertension
Revascularization is used to treat renovascular hypertension. Nevertheless, ACE inhibitors have a beneficial effect in patients with renovascular hypertension, both anticipating surgical intervention, and in patients whose conduct is not possible.
Treatment with Indapamide / Perindopril-Teva in patients with diagnosed or suspected renal artery stenosis should begin in a hospital with the recommended initial dose of Indapamide / Perindopril-Teva, controlling kidney function and potassium levels in the blood plasma. Some patients may develop functional acute renal failure, which is reversible after drug withdrawal.
Other risk groups
In patients with CHF (IV functional class by classificationNYHA) and patients with type 1 diabetes mellitus (the risk of spontaneous increase in potassium content) treatment should start with the recommended initial dose of the drug Indapamide / Perindopril-Teva and under the supervision of a doctor.
When using the drug Indapamide / Perindopril-Teva in patients with diabetes mellitus, receiving hypoglycemic drugs for ingestion or insulin, during the first month of therapy, it is necessary to regularly monitor the concentration of glucose in the blood.
Perindopril (as well as other ACE inhibitors) has a less pronounced antihypertensive effect in patients of the Negroid race compared with representatives of other races.
Surgical interventions / 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 the use of ACE inhibitors, including perindopril, 12 hours before surgery, warning the anesthesia doctor about the use of inhibitors APF.
Aortic stenosis / GOKMP
ACE inhibitors should be used with caution in patients with obstruction of the left ventricular outflow tract.
Liver failure
In rare cases, when taking ACE inhibitors, cholestatic jaundice occurs,with the progression of which fulminant hepatic necrosis develops, including fatal outcome. When jaundice or a significant increase in the activity of "liver" transaminases against the background of taking ACE inhibitors, the drug Indapamide / Perindopril-Teva should be discontinued.
Anemia
It can develop in patients after kidney transplantation or in patients on hemodialysis.
Hyperkalemia
In the treatment of ACE inhibitors, including perindopril, 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, including fatalities.Combined use of the above drugs should be done with caution.
Indapamide
The use of thiazide and thiazide-like diuretics in patients with impaired liver function can lead to the development of hepatic encephalopathy. In this case, stop taking the medication immediately.
Photosensitivity
There are reports of cases of increased photosensitivity against thiazide and thiazide-like diuretics. With the development of photosensitivity reaction against the background of taking the drug Indapamide / Perindopril-Teva treatment should be discontinued. If there is a need to resume the use of the drug Indapamide / Perindopril-Teva, it should protect the exposed areas of the skin from direct exposure to sunlight and artificial ultraviolet rays.
Water-electrolyte balance
The content of sodium in the blood plasma
Before starting treatment with the drug Indapamide / Perindopril-Teva it is necessary to determine the sodium content in the blood plasma and on the background of taking the drug to conduct regular monitoring of the content of electrolytes in the blood plasma. All diuretics are capable of causing hyponatremia, leading to serious complications.
The content of potassium in blood plasma
Therapy with thiazide and thiazide-like diuretics is associated with a risk of hypokalemia (less than 3.4 mmol / L) in elderly patients, depleted patients, patients with cirrhosis, patients with peripheral edema, ascites, IHD, XCH. Hypokalemia in these patients increases the toxic effect of cardiac glycosides and increases the risk of arrhythmia.
The high-risk group includes patients with an increased interval QT on the ECG. Hypokalemia, like bradycardia, contributes to the development of severe cardiac arrhythmias, especially arrhythmias such as pirouettes, which can lead to death. In all cases described, regular monitoring of the potassium content in the blood plasma is necessary. The first determination of the potassium content in blood plasma should be carried out during the first week after the initiation of therapy with Indapamide / Perindopril-Teva.
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.Before the study of the function of parathyroid glands, you should cancel the use of the drug Indapamide / Perindopril-Teva.
The concentration of glucose in the blood plasma
It is necessary to monitor the concentration of glucose in patients with diabetes mellitus.
Concentration of uric acid
In patients with a high concentration of uric acid in blood plasma against the background of therapy with the drug Indapamide / Perindopril-Teva may increase the frequency of exacerbation of the gout.
Diuretic drugs and kidney function
The effectiveness of thiazide and thiazide-like diuretics is fully manifested only under the condition of normal kidney function. They are also effective in the case of a creatinine concentration of less than 25 mg / l, i.e. 220 mmol / l in adults.
In elderly patients, the concentration of creatinine in the blood plasma should be adjusted taking into account the patient's age, body weight and sex Cockcroft formula:
CK = (140 - age (years)) x body weight (kg) / 0.814 x creatinine concentration (mol / l).
This formula is suitable for elderly male patients. When calculating QA for women, the coefficient is 0.85.
Hypovolley as a result of a decrease in BCC or hyponatremia caused by taking diuretics,at the beginning of treatment with the drug Indapamide / Perindopril-Teva can lead to a decrease in the glomerular filtration rate and accompanied by an increase in the concentration of creatinine and urea in the blood plasma.
Such temporary functional renal failure does not adversely affect normal renal function, but may worsen the existing renal failure.
Athletes
Indapamide can give a false positive reaction during doping control.
