IHD: a reduction in the risk of developing cardiovascular complications in patients who have had previous myocardial infarction and / or coronary revascularization
With the development of unstable angina (expressed or not) during the first month of therapy with Perineva® Cu-tab®, the benefits and risks should be assessed before continuing therapy.
ACE inhibitors can cause a sharp decrease in blood pressure. In patients with uncomplicated arterial hypertension a symptomatic decrease in blood pressure rarely occurs after taking the first dose. The risk of excessive reduction in blood pressure is increased in patients with reduced bcc in the background of diuretic therapy, with strict diet with restriction of table salt, hemodialysis, as well as with diarrhea or vomiting, or in patients with severe hypertension with high renin activity. A marked decrease in blood pressure was observed in patients with CHF IV of the functional class according to the classification NYHA, both in the presence of concomitant renal failure, and in its absence. The most common arterial hypotension can develop in patients with CHF IV functional class by classification NYHA, taking "loop" diuretics in high doses, as well as against hyponatremia or renal insufficiency. We recommend careful medical supervision (control of blood pressure, kidney function and potassium content in blood serum) when titrating the doses of the drug.This approach is also used in patients with ischemic heart disease or cerebrovascular disease, in whom excessive reduction of blood pressure can lead to myocardial infarction or stroke.
With a pronounced decrease in blood pressure, the patient should be transferred to the "lying" position on the back with raised legs and to carry out measures for replenishment of bcc with the intravenous injection of 0.9% sodium chloride solution. Transient arterial hypotension is not a contraindication for further therapy. After the recovery of bcc and blood pressure, treatment can be continued provided that the dose of the drug is carefully selected.
In some patients with CHF and normal or reduced BP during therapy with Perineva® Cu-tab®, an additional reduction in blood pressure is possible. 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 abolition of Perineva® Cu-tab® may be required.
Stenosis of the aortic and / or mitral valve / hypertrophic obstructive cardiomyopathy (GOKMP)
ACE inhibitors, incl. and perindopril, should be used with caution in patients with stenosis of the mitral valve and obstruction of the outflow tract of the left ventricle (aortic valve stenosis and GOKMP).
Impaired renal function
In patients with renal insufficiency (CC less than 60 ml / min), the initial dose of the drug should be selected according to the QC (see the section "Dosing and Administration") and then, depending on the therapeutic response. For such patients, regular monitoring of serum potassium and serum creatinine 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. Possible development of acute renal failure, usually reversible.
In some patients with bilateral stenosis of the renal arteries or stenosis of the artery of a single kidney (especially in the presence of renal failure) against the background of therapy with ACE inhibitors, there was an increase in serum concentrations of urea and creatinine, reversible after the abolition of therapy. In patients with renovascular hypertension, with the therapy of ACE inhibitors, there is an increased risk of a marked decrease in blood pressure and renal insufficiency.Treatment of such patients should begin under careful medical supervision, with small doses of perindopril and with further adequate dose selection. As an initial therapy, the preparation Perineva® Ku-tab® should not be used in such patients (for these dosages). During the first weeks of therapy, it is necessary to cancel diuretics and regularly monitor kidney function.
In some patients with arterial hypertension, in the presence of previously unidentified renal failure, especially with concomitant diuretic therapy, there was a slight and temporary increase in the concentration of urea and creatinine in the serum. In this case, it is recommended to reduce the dose of Perineva® Cu-tab® and / or to cancel the diuretic.
Hemodialysis
In patients on dialysis using high-flow membranes (for example, AN 69®), 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
Experience with perindopril in patients after a recent transplantation of the kidney is absent.
Increased sensitivity / angioedema
Rarely in patients taking ACE inhibitors, incl. perindopril, it is possible to develop an angioedema of the face, extremities, lips, mucous membranes, tongue, vocal cords and / or larynx. With the development of angioneurotic edema treatment should be immediately stopped, the patient should be under medical supervision until the symptoms disappear completely. Angioedema of the lips and face usually does not require treatment and passes by itself; To reduce the severity of symptoms, you can use antihistamines.
Angioedema, swelling of the tongue, vocal cords or larynx can lead to death. Swelling of the tongue, vocal cords or larynx may be accompanied by the development of airway obstruction. With the development of angioedema, immediately subcutaneously epinephrine (epinephrine) and ensure airway patency.
Patients with a history of angioedema, who are not associated with the use of ACE inhibitors, may be at increased risk of developing angioedema when taking drugs of this group.
In rare cases, against the background of therapy with ACE inhibitors, angioedema develops in the intestine. In this case, patients have abdominal pain, possibly in combination with nausea or vomiting; in some cases without a previous angioedema and a normal level of C1-esterase. Diagnosed with computer tomography or ultrasound examination of the abdominal organs, or during a surgical procedure. Symptoms disappear after discontinuing therapy with an ACE inhibitor. Patients receiving ACE inhibitors should consider the possibility of angioedema edema in the differential diagnosis of abdominal pain.
Anaphylactoid reactions during the procedure of apheresis of low density lipoproteins (LDL)
In patients receiving ACE inhibitors, amid the procedure of apheresis of LDL with the use of dextran sulfate, in rare cases, the development of anaphylactoid reactions is possible. It is recommended that the ACE inhibitor be temporarily withdrawn before each procedure for LDL apheresis.
Anaphylactic reactions during desensitization
In patients receiving ACE inhibitors during the course of desensitization (for example, the venom of Hymenoptera insects), in very rare cases development of long-term, life-threatening anaphylactoid reactions is possible. It should be used with caution in patients predisposed to allergic reactions. It is recommended that the ACE inhibitor be temporarily withdrawn 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 an ACE inhibitor or there is a significant increase in the activity of "liver" enzymes, the ACE inhibitor should be immediately discontinued and the patient should be closely monitored.
Neutropenia / agranulocytosis / thrombocytopenia / anemia
In patients on the background of therapy with ACE 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.Perineva® Cu-tab® should be used with extreme caution in patients with systemic connective tissue diseases (eg, systemic lupus erythematosus, scleroderma) who are simultaneously receiving immunosuppressive therapy, allopurinol or procainamide, and also at a combination of all listed factors, especially at an existing infringement of function of kidneys. Such patients may develop severe infections that do not respond to intensive antibiotic therapy. When carrying out therapy with Perineva® Cu-tab®, these patients should regularly monitor the number of leukocytes in the blood serum. Patients should inform the doctor of any signs of infectious diseases (eg, sore throat, fever).
Ethnic differences
The risk of angioedema development in patients of the Negroid race is higher. 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 / 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. The day before the surgery, therapy with ACE inhibitors should be canceled. If the ACE inhibitor can not be canceled, then the arterial hypotension, which develops according to the mechanism described, can be corrected by an increase in BCC. It is necessary to warn the surgeon that the patient is taking ACE inhibitors.
Hyperkalemia
Against the background of therapy with ACE inhibitors, including perindopril, in some patients may be increasedwthe content of potassium in the blood serum. Risk factors for hyperkalemia are renal and / or heart failure, diabetes mellitus in decompensation stage, simultaneous intake of potassium-sparing diuretics, potassium preparations,or potassium-containing substitutes for edible salt, or other drugs that cause hyperkalemia (eg, heparin), especially in patients with impaired renal function. Hyperkalemia can lead to serious, sometimes fatal, heart rhythm disturbances. If it is necessary to simultaneously use these drugs, it is recommended to regularly monitor the potassium content in the blood serum.
Diabetes
In patients with diabetes mellitus, who take hypoglycemic agents for ingestion or insulin, during the first month of therapy with ACE inhibitors, the concentration of glucose in the blood should be carefully monitored.
Lithium preparations
It is not recommended simultaneous use with lithium preparations.
Potassium-sparing diuretics, preparations containing potassium and potassium-containing substitutes for edible salt
It is not recommended simultaneous use with ACE inhibitors.
