Lithium preparations
It is not recommended simultaneous use of the drug Perindid with lithium preparations.
Impaired renal function
Therapy with Perindid is contraindicated in patients with severe renal insufficiency (CC less than 30 ml / min). In some patients with hypertension without a previous impairment of renal function against the background of therapy with Perindid, there may be signs of acute renal failure. In this case, treatment with Perindid should be discontinued.In the future, you can resume combination therapy, using low doses of Perindid, or use drugs perindopril and indapamide in monotherapy.
Such patients need regular monitoring of potassium and creatinine in the blood serum every 2 weeks after the start of therapy and every subsequent 2 months of therapy with Perindid.
Acute renal failure often develops in patients with severe CHF or initial renal impairment, including bilateral renal artery stenosis or arterial stenosis of a single functioning kidney.
The drug Perindid is not recommended for 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
Hyponatremia is associated with a risk of sudden development of arterial hypotension (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.Such patients need regular monitoring of electrolytes in blood plasma.
With severe arterial hypotension, a 0.9% solution of sodium chloride may be required.
Transient arterial hypotension is not a contraindication for further continuation of therapy. After the recovery of bcc and blood pressure, you can resume therapy with Perindid using low doses of the drug, or use drugs perindopril and indapamide in monotherapy.
The content of potassium
The combined use of perindopril and indapamide does not prevent the development of hypokalemia, especially in patients with diabetes mellitus or renal insufficiency. As in the case of combined use of antihypertensive drugs and diuretic, regular monitoring of the potassium content in the blood plasma is necessary.
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 in the absence of other complications, neutropenia develops rarely and passes on its own after the withdrawal of ACE inhibitors.
Perindopril should be used with great care in patients with connective tissue diseases 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 the appointment of perindopril, it is recommended to periodically monitor the white blood cells 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.
Hypersensitivity / angioedema (angioedema)
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 monitored until the signs of edema disappear completely.
If angioedema affects only the face and lips, then its manifestations usually go away alone 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.
When such symptoms occur, immediately enter subcutaneously epinephrine (adrenaline) (at 1: 1000 dilution (0.3 or 0.5 mL) and / or provide airway patency.
Patients with a history of Quincke 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 in combination with nausea and vomiting, in some cases without a prior angioedema and with normal 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 in the course of differential diagnosis, it is necessary to consider the possibility of developing angioedema 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). ACE inhibitors should be used with caution in patients prone to allergic reactions undergoing desensitization procedures. The appointment of an ACE inhibitor should be avoided for patients receiving immunotherapy with venom of Hymenoptera. Nevertheless, 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 at an apheresis of LDL
In rare cases, patients receiving ACE inhibitors may develop life-threatening anaphylactoid reactions in LDL-apheresis using dextran 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 use an antihypertensive drug of another pharmacotherapeutic group (see the section "With caution").
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 therapy with an ACE inhibitor is necessary for the patient, the Perindide drug may be continued.
Children and teenagers under the age of 18
The drug Perindid is contraindicated in children and adolescents under the age of 18 due to lack of data on efficacy and safety of use.
The risk of arterial hypotension and / or renal insufficiency in patients with CHF, violation of water-electrolyte balance, etc..)
In liver cirrhosis accompanied by edema and ascites, arterial hypotension, CHF, there may be a significant activation of the renin-angiotensin-aldosterone system (RAAS),especially with severe hypovolemia and a decrease in the content of electrolytes 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 causes blockade of the RAAS; in this connection, a sharp decrease in blood pressure and / or an increase in the concentration of creatinine in the blood plasma, indicating the development of acute renal failure, which is more often observed with the first dose of Perindid or during the first two weeks of therapy.
Elderly patients
Before starting the Perindid preparation, you should evaluate the kidney function and the potassium content in the blood plasma. The initial dose of the drug Perindid 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 Perindid in patients with coronary heart disease and cerebral circulatory insufficiency. In such patients, treatment should be started with a dose of 2 mg + 0.625 mg of Perindid (initial dose).
Renovascular hypertension
Treatment of Perindid with patients diagnosed or suspected renal artery stenosis should begin in a hospital with a dose of Perindid 2 mg + 0.625 mg, monitoring the function of the kidneys and the content of potassium in the blood plasma. Some patients may develop acute renal failure, which is reversible after discontinuation of the drug.
Other risk groups
In patients with CHF (IV functional class by classification NYHA) Patients with type 1 diabetes mellitus (the risk of spontaneous increase in potassium content) treatment should begin with an initial dose of 2 mg + 0.625 mg of Perindid and under medical supervision.
Patients with diabetes mellitus
When prescribing Perindid, patients with diabetes mellitus who receive hypoglycemic agents for ingestion or insulin during the first month of therapy should regularly monitor the concentration of glucose in the blood.
Ethnic Features
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 procedures / General anesthesia
The use of ACE inhibitors in patients undergoing surgery with the use of 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 ACE inhibitors.
Aortic stenosis / mitral Stenosis / Hypertrophic obstructive cardiomyopathy
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 liver necrosis develops, sometimes fatal. The mechanism of the syndrome is unclear. When jaundice or a significant increase in activity "liver" transaminases in patients receiving an ACE inhibitor reception Perindid preparation should be discontinued.
Anemia
Anemia can develop in patients after kidney transplantation or in patients on hemodialysis.
Hyperkalemia
It can develop during treatment with ACE inhibitors, including perinoplasty. 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. Combined use of the above drugs should be done with caution.
Indapamide
Photosensitivity
There are reports of cases of increased photosensitivity against thiazide and thiazide-like diuretics. When the photosensitivity reaction develops against the background of taking Perindid, treatment should be stopped. If there is a need to resume the use of Perindid,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 the treatment with Perindid, 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 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 patients: the elderly, depleted patients, patients with cirrhosis, peripheral edema, ascites, coronary heart disease, CHF. 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 be lethal.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 within the first week after the beginning of therapy with Perindid.
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 abolish Perindid.
The concentration of glucose in the blood plasma
It is necessary to monitor the concentration of glucose in patients with diabetes mellitus.
Uric acid
In patients with a high concentration of uric acid in blood plasma against the background of therapy with Perindid, the frequency of exacerbation of the gout current may increase.
Diuretics and kidney function
Hypovolemia due to a decrease in bcc or hyponatremia caused by diuretics at the beginning of treatment with Perindid may lead to a decrease in the glomerular filtration rate and be accompanied by an increase in the concentration of creatinine and urea in the blood plasma.
Athletes
Indapamide can give a positive reaction during doping control.
