Special instructions Stable ischemic heart disease
When the episode of unstable angina develops (significant or not), during the first month of therapy with Perindopril-Teva it is necessary to evaluate the benefit / risk ratio for therapy with this drug.
Arterial hypotension
ACE inhibitors can cause a sharp decrease in blood pressure. In patients with uncomplicated arterial hypertension, symptomatic arterial hypotension rarely occurs after taking the first dose. The risk of excessive reduction in blood pressure is increased in patients with a reduced bcc against diuretic therapy, with strict salt-free diet, hemodialysis, as well as with diarrhea or vomiting, or with severe renin-dependent hypertension. The expressed arterial hypotension was observed in patients with severe CHF, as in the presence of concomitant renal insufficiency, as well as in the absence. The most common arterial hypotension can develop in patients with more severe CHF, taking "loop" diuretics in high doses, as well as against hyponatremia or kidney failure. These patients are recommended careful medical supervision at the beginning of therapy and when titrating doses of the drug.The same applies to patients with IHD or cerebrovascular disease, in whom excessive reduction of blood pressure can lead to myocardial infarction or cerebrovascular complications.
In case of development of arterial hypotension, it is necessary to give the patient a horizontal position with raised legs, and if necessary, administer intravenously 0.9% solution of sodium chloride to increase the BCC. Transient arterial hypotension ns is a contraindication for further therapy. After the recovery of bcc and LD, treatment can be continued provided that the dose of the drug is carefully selected.
In some patients with CHF and normal or low LD during therapy with the drug Perindopril-Teva, there may be an additional reduction in blood pressure. This effect is expected and usually is not a basis for drug discontinuation. If arterial hypotension is accompanied by clinical manifestations, a dose reduction or drug cancellation may be required Perindopril -Teva Impaired renal function
In patients with renal insufficiency (CC less than 60 ml / min), the initial dose of Perindopril-Teva should be matched in accordance with QC (see Fig.section "Method of administration and dose") and then - depending on the therapeutic response. For such patients, regular monitoring of the potassium content and serum creatinine concentration is necessary.
In patients with symptomatic heart failure, arterial hypotension, which develops during the initial period of therapy with ACE inhibitors. can lead to impaired renal function. In these patients, sometimes there were cases of acute renal failure, usually reversible.
In some patients with bilateral renal artery stenosis or stenosis of the renal artery to a solitary kidney (especially in the presence of renal failure) during therapy with ACE inhibitors was an increase in serum concentrations of urea and creatinine, reversible after discontinuation of therapy.
In patients with renovaecular hypertension in patients with ACE inhibitors, there is an increased risk of severe arterial hypotension and renal insufficiency. Treatment of such patients should start under close medical supervision with low doses and with further adequate dose selection.During the first weeks of therapy with the drug Perindopril-Teva, it is necessary to cancel diuretics and regularly monitor the kidney function.
In some patients with arterial hypertension, in the presence of previously unrecognized renal failure, especially with concomitant diuretic therapy, there was a slight and temporary increase in the concentration of urea and creatinine in the blood supply. In this case, a reduction in the dose of Perindopril-Teva and / or removal of the diuretic is recommended.
Patients on hemodialysis
In patients on dialysis using high-flux membranes and concurrently taking ACE inhibitors, several cases of persistent, life-threatening anaphylactic reactions were noted. If you need hemodialysis, you need to use a different type of membrane.
Kidney Transplantation
The experience of using the drug Perindopril-Teva in patients after the recent transplantation of the night is absent.
Hypersensitivity, angioedema
Rarely, in patients taking ACE inhibitors, incl. perindopril, developed angioedema, edema of the face, limbs, lips. tongue, vocal folds and / or larynx. This condition can develop at any time of treatment. With the development of angioedema, treatment should immediately be discontinued, the patient should be under medical supervision until the symptoms disappear completely. Angioedema of the lips and face usually does not require treatment; To reduce the severity of symptoms, you can use antihistamines. Angioedema, swelling of the tongue, vocal cords or larynx can lead to a legal outcome. With the development of angioedema, immediately subcutaneously epinephrine (epinephrine) and ensure airway patency. Patients with an angioneurotic edema in the history, ns associated with the use of ACE inhibitors, may be at high risk of developing angioedema while taking an ACE inhibitor.
Anaphylactoid reactions during the procedure of apheresis of low-density lipoproteins (LDL-apheresis)
In patients with the appointment of ACE inhibitors against the background of the procedure of LDL-apheresis with the help of dextran sulfate, in rare cases, the development of an anaphylactic reaction is possible. A temporary withdrawal of an ACE inhibitor is recommended before each apheresis procedure.
Anaphylactic reactions during desensitization
In patients receiving ACE inhibitors during the course of desensitization (for example, the venom of Hymenoptera), in very rare cases development of life threatening anaphylactic reactions is possible. A temporary withdrawal of the ACE inhibitor is recommended before each desensitization procedure begins.
Liver failure
During therapy with ACE inhibitors, it is sometimes possible to develop a syndrome that starts with cholestatic jaundice and then progresses to fulminant liver necrosis, sometimes with a fatal outcome. The mechanism of development of this syndrome is unclear. If jaundice appears during the administration of the DFT inhibitor or the activity of "liver" enzymes is increased, the ACE inhibitor should be immediately discontinued and the patient should be carefully monitored. It is also necessary to conduct an appropriate examination.
Neutropenia, agranulocytosis, thrombocytopenia, anemia
In patients on the background of therapy with AIF inhibitors, cases of development of neutropenia, agranulocytosis, thrombocytopenia and anemia were noted. With normal kidney function, in the absence of other complications, neutropenia develops rarely. The drug Perindopril-Teva should be used with great care in patients with systemic connective tissue diseases (eg, systemic lupus erythematosus, scleroderma), simultaneously receiving immunosuppressive therapy, allopurinol or procainamide, as well as when combining all of these factors, especially if there is an existing impairment of kidney function. Such patients are possible development of severe infections, not amenable intensive antibiotic therapy. When performing therapy with Perindopril-Teva in patients with the above factors recommended periodically monitor the number of leukocytes in the blood and warn the patient about the need to inform the doctor about the appearance of any symptoms of infection.
In patients with congenital deficiency of glucose-6-phosphate dehydrogenase, isolated cases of development of hemolytic anemia were noted.
Negroid race
Like other ACE inhibitors. perindopril is less effective in reducing blood pressure in patients of the Negroid race, possibly because of the greater prevalence of low-grade conditions in the population of this group of patients with hypertension.
Cough
Against the background of therapy with ACE inhibitors, a persistent, unproductive cough may develop, which stops after the drug is discontinued. This should be taken into account in the differential diagnosis of cough.
Surgery and general anesthesia
In patients whose condition requires extensive surgical intervention or general anesthesia with drugs that cause arterial hypotension, ACE inhibitors. including perindopril, can block the formation of angiotensin II with compensatory release of renin. One day before surgery, therapy with AIF inhibitors should be canceled. If the ACE inhibitor can not be canceled, then the arterial hypotension, which develops but the mechanism described, can be corrected by an increase in BCC.
Hyperkalemia
Against the background of therapy with ACE inhibitors, including perindopril, in some patients the potassium content in the blood can increase.The risk of hyperkalemia is elevated in patients with renal and / or heart failure, decomposed diabetes mellitus, and in patients using potassium-sparing diuretics, potassium preparations or other drugs that cause hyperkalismia (eg, heparin). If it is necessary to simultaneously prescribe these drugs, it is recommended to regularly monitor the potassium content in the blood serum.
Diabetes
In patients with diabetes who take hypoglycemic agents for ingestion or insulin, in the first few months of therapy with ACE inhibitors, the concentration of glucose in the blood should be carefully monitored.
Lactose
Tablets Perindopril-Teva contain lactose. Therefore, patients with hereditary lactose intolerance, lactase deficiency or malabsorption syndrome should not take this medication.
Double blockade of RA AS
Arterial hypotension, fainting, stroke, hyperkalemia and renal dysfunction (including acute renal failure) have been reported in susceptible patients, especially when used with medications that affect this system.Therefore, the double blockade of RAAS due to a combination of an ACE inhibitor with ARAP or aliskiren is not recommended. The combination with aliskiren is contraindicated in patients with diabetes mellitus or impaired function of the night (GFR <60 mL / min / 1.73 m2).
