Special instructions relating to amlodipine and perindopril are also applicable to the preparation of Dalnev®.
Perindopril
Double blockade of RAAS
It has been proven that simultaneous use of ACE inhibitors, ARA II or aliskiren increases the risk of arterial hypotension, hyperkalemia and decreased renal function (including acute renal failure). Therefore, double blockade of RAAS by simultaneous use of ACE inhibitors, APA II or aliskiren is not recommended.
In case of simultaneous use of these drugs, therapy should be performed only under the supervision of a doctor and subject to constant monitoring of kidney function, electrolyte content and blood pressure.
Do not simultaneously use ACE inhibitors and APA II in patients with diabetic nephropathy.
Hypersensitivity / angioedema (angioedema)
With the use of ACE inhibitors, including perindopril, in rare cases, angioedema may develop in the face, lips, tongue, vocal cords, and / or larynx. When these symptoms appear, the use of the Dalneva® preparation should be stopped immediately, the patient should be observed 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 (epinephrine) in a dilution of 1: 1000 (0.3 or 0.5 ml) and / or provide airway patency. The patient should be under medical supervision until the symptoms disappear completely and persistently.
Patients with a history of Quincke edema not associated with the use of ACE inhibitors may be at increased risk of developing it with the use of drugs of this group.
In rare cases, on the background of therapy with ACE inhibitors, intestinal angioedema develops (angioedema of 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 at a normal serum concentration of 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 the cessation of the use 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 procedures
There are separate reports on the development of long-term, life-threatening anaphylactoid reactions in patients receiving ACE inhibitors during desensitizing therapy with Hymenoptera insects.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 during apheresis of LDL with dextran sulfate
In rare cases, in patients receiving ACE inhibitors, when performing low-density lipoprotein (LDL) apheresis using dextran sulfate may develop life threatening anaphylactoid reactions. To prevent anaphylactoid reaction, ACE inhibitor therapy should be discontinued before each procedure for LDL apheresis using dextran sulfate.
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 applyantihypertensive drug of another pharmacotherapeutic group.
Neutropenia / agranulocytosis, thrombocytopenia and anemia
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. Some patients may develop severe infections that are not amenable to intensive antibiotic therapy. In the case of prescribing perindopril, it is recommended to control the amount of blood leukocytes. The patient should be warned that in case of any signs of an infectious disease (sore throat, fever), you should immediately consult a doctor.
The risk of developing arterial hypotension and / or renal failure (in patients with CHF,violation of water-electrolyte balance, etc.)
With cirrhosis of the liver, accompanied by edema and ascites, arterial hypotension. CHF may show a significant activation of RAAS, especially in severe hypovolemia and a decrease in the content of electrolytes in blood plasma (against a diet with restriction of table salt or long-term use 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 plasma creatinine concentration, which indicates the development of acute renal failure, is more likely to occur with the first dose or during the first two weeks of therapy with Dalnev®.
ACE inhibitors can cause a sharp decrease in blood pressure. Symptomatic arterial hypotension rarely occurs in patients without concomitant diseases. The risk of a marked decrease in blood pressure was elevated in patients with reduced BCC. which can be observed against diuretic therapy, with strict diet with restriction of table salt, hemodialysis, with diarrhea or vomiting, or in patients with high-grade arterial hypertension with high renin activity.Patients with a high risk of developing symptomatic arterial hypotension should carefully monitor blood pressure, kidney function and potassium levels in the blood serum during therapy with Dalnev®.
The same precautions apply to patients with angina or cerebrovascular disease, in whom a marked decrease in blood pressure may lead to the development of myocardial infarction or impaired cerebral circulation.
In the case of development of arterial hypotension the patient should be transferred to the "lying" position on the back with raised legs. If necessary, replenish bcc by intravenous injection of 0.9% sodium chloride solution. Transient arterial hypotension is not a contraindication for the further administration of Dalnev®. After the recovery of bcc and AD, treatment with Dalnev® can be continued.
Aortic stenosis / mitral stenosis / Hypertrophic obstructive cardiomyopathy
ACE inhibitors should be used with caution in patients with obstruction of the left ventricular outflow tract (aortic stenosis, hypertrophic obstructive cardiomyopathy), as well as in patients with mitral stenosis.
Potassium-sparing diuretics and potassium preparations
Simultaneous use of perindopril and potassium-sparing diuretics, as well as potassium and potassium-containing substitutes for table salt is not recommended.
Cough
Against the background of therapy with an ACE inhibitor, a dry, unproductive cough may occur that disappears after the withdrawal of this group. When dry cough occurs, remember the possible association of this symptom with the use of an ACE inhibitor.
Children and teenagers under the age of 18
The drug Dalneva® is contraindicated in children and adolescents under the age of 18 due to the lack of data on the efficacy and safety of the drug in this age group.
Impaired renal function
In some patients with bilateral stenosis of the renal arteries or stenosis of the artery of a single kidney, taking ACE inhibitors, there was an increase in urea and creatinine levels in the blood plasma, reversible after the withdrawal of therapy. These changes are more likely in patients with renal insufficiency. In patients with renovascular hypertension, there is an increased risk of severe arterial hypotension and renal failure.
In some patients with hypertension without obvious signs of existing kidney diseases that have been taking perindopril simultaneously with the diuretic, there was a small and temporary increase in the concentrations of urea and creatinine in the blood serum. These changes often develop in patients with a previous impairment of kidney function.
Impaired liver function
Rarely, the use of ACE inhibitors is accompanied by a syndrome, the development of which begins with cholestatic jaundice and which then progresses to fulminant liver necrosis, sometimes fatal. The mechanism of development of this syndrome is unclear. If during the application of the ACE inhibitor jaundice appears or the activity of "liver" transaminases in blood plasma increases, the ACE inhibitor should be immediately canceled, and the patient must remain under appropriate medical supervision.
Ethnic Features
In patients of the Negroid race more often than in the representatives of other races, against the background of the use of ACE inhibitors, angioedema develops. Perindopril, as well as other ACE inhibitors, may have a less pronounced antihypertensive effect in patients of the Negroid race compared with representatives of other races.Perhaps this difference is due to the fact that patients with Negroid races with arterial hypertension are more likely to have low renin plasma activity.
Surgical procedures / General anesthesia
The use of ACE inhibitors in patients undergoing extensive surgery and / or general anesthesia can lead to a marked decrease in blood pressure if general anesthetics with an antihypertensive effect are used. This is due to the blocking of the formation of angiotensin II against a background of compensatory enhancement of renin activity. If the development of arterial hypotension is associated with the mechanism described, the BCC should be increased. It is recommended to stop using the drug 24 hours before surgery.
Hyperkalemia
Against the background of therapy with ACE inhibitors, including perindopril, in some patients, the potassium content in the blood plasma may increase. Risk factors for hyperkalemia include renal failure, decreased renal function, elderly age (over 70 years), diabetes mellitus, intercurrent conditions, in particular, dehydration, acute cardiac decompensation, metabolic acidosis, simultaneous use of potassium-sparing diuretics (eg, spironolactone, eplerenone, triamterene or amiloride), potassium preparations or potassium-containing substitutes for edible salt or the simultaneous use of other drugs that increase the potassium content in the blood plasma (eg, heparin).
Hyperkalemia can cause serious, sometimes life-threatening arrhythmias. If you need to simultaneously use perindopril and one of the above substances, you should be careful and regularly monitor the potassium content in the blood plasma.
Patients with diabetes mellitus
In patients with diabetes who take hypoglycemic agents for ingestion and / or insulin, in the first few months of therapy with ACE inhibitors, careful monitoring of blood glucose concentration is necessary.
Amlodipine
Impaired liver function
In patients with impaired liver function T1/2 Amlodipine is lengthened. When prescribing the drug, such patients should be careful and regularly monitor the activity of "liver" enzymes in the blood plasma.
Patients with heart failure
In patients with CHF (III and IV functional class by classification NYHA) treatment is conducted with caution, in connection with the possibility of developing pulmonary edema.
