All special instructions and precautions relating to each component are applicable to Prestilol®.
Severe arterial hypotension
ACE inhibitors can cause a sharp decrease in blood pressure. Severe arterial hypotension rarely develops in patients with uncomplicated course of arterial hypertension. The risk of excessive reduction in blood pressure is increased in patients with reduced bcc, for example, with diuretic therapy, with a strict salt-free diet, with hemodialysis, diarrhea or vomiting, as well as in patients with severe hypertension with high renin activity (see.sections "Interaction with other medicinal products" and "Side effect"). The expressed arterial hypotension can be observed at patients with clinical displays of intimate insufficiency both with presence, and without renal insufficiency. This risk is more likely in patients with severe heart failure, as a response to the use of "loop" diuretics, hyponatremia or functional renal failure. Patients with an increased risk of developing symptomatic arterial hypotension during the initiation of therapy and dose adjustment should be under close medical supervision. This approach is also applied to patients with IHD or cerebrovascular disease, in whom excessive reduction of blood pressure can lead to the development of myocardial infarction or acute impairment of cerebral circulation.
With the development of arterial hypotension, the patient should be placed in the "lying down" position and, if necessary, an intravenous infusion of 9 mg / ml (0.9%) sodium chloride solution. Transient arterial hypotension is not a contraindication for further administration of the drug.As a rule, taking the drug can be continued after replenishment of bcc and increased blood pressure.
In some patients with CHF, who have normal or low blood pressure, there may be an additional reduction in blood pressure as a result of perindopril. This effect is predictable and usually does not require discontinuation of therapy. With the development of symptoms of arterial hypotension, a dose reduction or gradual withdrawal of the drug, or the use of its individual components in the form of monotherapy, may be required.
Hypersensitivity / angioedema
There have been reports of rare cases of angioedema of the face, extremities, lips, mucous membranes, tongue, glottis and / or larynx in patients treated with ACE inhibitors, including perindopril (see section "Side effect"). These phenomena can develop at any time of treatment. In such cases, stop treatment with Prestilol® immediately. Therapy with beta-blockers should be continued. The patient should be observed until the signs of edema disappear completely. In cases where the edema affects only the face and lips, the condition is usually resolved without treatment, although antihistamines may be used to alleviate the symptoms.
Angioedema, accompanied by swelling of the larynx, can lead to death. Swelling of the tongue, vocal cords, or larynx can lead to airway obstruction. When these symptoms appear, emergency therapy is required, including subcutaneous injection of epinephrine (adrenaline) and / or ensuring airway patency. The patient should be under medical supervision until the symptoms disappear completely and persistently. If a patient has a history of angioedema, an unrelated ACE inhibitor. the risk of developing angioedema may be elevated when taking an ACE inhibitor (see "Contraindications").
In rare cases, patients treated with ACE inhibitors. the development of angioedema of the intestine was described. In this case, patients had abdominal pain as an isolated symptom or in combination with nausea and vomiting, in some cases without a previous angioedema and at a normal level of C-1 esterase. The diagnosis is established by means of computed tomography of the abdominal cavity, ultrasound examination or surgical intervention. Symptoms disappeared after discontinuation of ACE inhibitors.Therefore, patients with abdominal pain receiving ACE inhibitors should take into account the possibility of developing angioedema of the intestine during differential diagnosis.
Inhibitors mTOR (eg, sirolimus, everolimus, tessirolimus):
In patients who are simultaneously receiving therapy with inhibitors mTOR (eg, sirolimus, everolimus, tessirolimus), the risk of developing angioedema (including edema of the respiratory tract or tongue with / without respiratory function impairment) may increase (see "Interaction with Other Drugs").
Liver failure
In rare cases, against the background of the administration of ACE inhibitors, there is a syndrome of development of cholestatic jaundice with the transition to fulminant liver necrosis, sometimes with a lethal outcome. The mechanism of development of this syndrome is unclear. Patients taking ACE inhibitors who develop jaundice or a significant increase in liver enzyme activity should stop taking an ACE inhibitor and receive appropriate medical supervision (see "Side effect" section).
Ethnic differences
In patients of the Negroid race, ACE inhibitors cause angioedema more often than patients who are representatives of other races.
Like other ACE inhibitors, in representatives of the Negroid race perindopril may be less effective in lowering blood pressure than in representatives of other races, which may be due to the higher prevalence of low-grade conditions in patients of the Negroid race with hypertension.
Cough
With the use of ACE inhibitors, cough may occur. It is characteristic that cough is dry, persistent and is resolved after discontinuation of therapy. This should be taken into account in the differential diagnosis of cough.
Hyperkalemia
In some patients receiving ACE inhibitors, including perindopril, an increase in the serum potassium concentration was observed. Risk factors for hyperkalemia include renal failure, impaired liver function, age over 70 years, diabetes mellitus, certain concomitant conditions (dehydration, acute cardiac decompensation, metabolic acidosis) and concomitant use of potassium-sparing diuretics (eg, spironolactone, eplerenone, triamterene or amiloride), preparations of potassium or potassium-containing substitutes for edible salt / food additives. Patients taking other drugs that promote serum potassium levels (eg, heparin) are also at risk. The use of potassium, potassium-sparing diuretics or potassium-containing salt substitutes / nutritional supplements, especially in patients with impaired renal function, can lead to a significant increase in serum potassium concentration. Hyperkalemia can lead to serious, sometimes fatal, heart rhythm disturbances. If simultaneous reception of the above mentioned means is necessary, they should be applied with caution against the background of regular monitoring of potassium content in the blood serum (see section "Interaction with other medicinal products").
Lithium preparations
Simultaneous use of perindopril and lithium preparations is not recommended (see the section "Interaction with Other Drugs").
Potassium-sparing diuretics, potassium preparations, potassium-containing substitutes for edible salt and food additives
The simultaneous use of perindopril andpotassium-sparing diuretics, and also preparations of potassium, potassium-containing substitutes for edible salt and food additives (see the section "Interaction with other medicinal products").
Double blockade of the renin-angiotensin-aldosterone system
There is evidence that joint use of ACE inhibitors, angiotensin II receptor blockers, or aliskiren increases the risk of hypotension, hyperkalemia and renal dysfunction (including acute renal failure). Thus, a double blockade of RAAS by the combined use of ACE inhibitors. blockers of angiotensin II receptors or aliskiren is not recommended (see the sections "Interaction with other medicinal products" and "Pharmacodynamics"). If double blockade therapy is considered absolutely necessary, it should be performed only under strict medical supervision and with regular monitoring of kidney function, electrolyte content in blood and blood pressure.
Do not use ACE inhibitors in combination with angiotensin II receptor blockers in patients with diabetic nephropathy.
Blockers of "slow" calcium channels, antiarrhythmics of the first class and antihypertensive agents of central action
Simultaneous use of bisoprolol and calcium channel blockers, such as verapamil or diltiazem, anti-arrhythmic drugs of the first class and antihypertensive agents of central action are not recommended (see the section "Interaction with other medicinal products").
Abolition of the drug
It should avoid abrupt cessation of treatment with beta-blockers. especially in patients with ischemic heart disease, as this can lead to a temporary deterioration in cardiac activity. The dose should be reduced gradually, using individual components., Preferably for 2 weeks and in parallel with the onset of replacement therapy (if necessary).
Bradycardia
If, during treatment, the heart rate at rest is reduced to 50-55 beats per minute or less, and the patient has symptoms associated with bradycardia, a reduction in the dose of Prestilol® should be started using individual components with an acceptable dose of bisoprolol.
AV blockade of 1 degree
Given the negative dromotropic effect, prescribe beta-blockers to patients with AV blockade 1 degree should be done with caution.
Mitral stenosis / aortic stenosis / hypertrophic cardiomyopathy
As with other ACE inhibitors, perindopril caution should be given to patients with stenosis of the mitral valve and obstruction of the exit tract left ventricle, for example, with stenosis of the aortic valve or mri hypertrophic cardiomyopathy.
Prinzmetal's angina pectoris:
Beta-blockers may increase the incidence and duration of angina episodes in patients with Prinzmetal angina pectoris. The use of selective beta 1-adrenoblockers is possible with mild disease and only in combination with vasodilators.
Renal insufficiency:
In the case of kidney failure, the daily dose of the drug Prestylol® is selected depending on the creatinine clearance (see section "Method of administration and dose"). For these patients, part of the usual therapeutic practice is the standard control of the potassium and creatinine concentrations in the blood (see the "Side effect" section).
In patients with clinically significant symptoms of heart failure, arterial hypotension as a result of the initiation of treatment with ACE inhibitors may lead to further deterioration in kidney function.There was reported acute renal failure, which was usually reversible.
In some patients with bilateral stenosis of the renal arteries or stenosis of the artery of a single kidney that received therapy with ACE inhibitors, there was an increase in the level of urea and creatinine in the blood serum, which usually occurs when therapy is withdrawn. This effect was more often observed in patients with renal insufficiency. The additional presence of reninvascular hypertension causes an increased risk of severe arterial hypotension and renal insufficiency in such patients. Treatment in such patients should start with low doses under close medical supervision and with careful titration of the dose. Since diuretic therapy can contribute to the development of the phenomena described above, diuretics should be temporarily discontinued and monitoring of renal function should be performed during the first weeks of therapy. In some patients with arterial hypertension without signs of renal vascular disease, there was an increase in the concentration of urea and creatinine in the serum, usually minor and transient,especially with the simultaneous administration of perindopril and a diuretic. More likely the development of such phenomena in patients with a history of renal dysfunction. Dose reduction and / or cancellation of the diuretic and / or perindopril may be required.
Kidney Transplantation
The experience of treatment with perindopril arginine patients with a previously transplanted kidney is absent.
Patients on hemodialysis
In patients undergoing hemodialysis using high-flux membranes that received an ACE inhibitor, cases of anaphylactoid reactions were noted. Such patients should prescribe a hypotensive drug of another class or use a dialysis membrane of a different type.
Anaphylactoid reactions during apheresis of low density lipoproteins
In patients receiving ACE inhibitors, during the procedure of apheresis of LDL with the use of dextran sulfate, the development of life threatening anaphylactoid reactions was rarely observed. These reactions could be prevented by temporarily discontinuing therapy with an ACE inhibitor before each apheresis procedure.
Anaphylactoid reactions during desensitization
Anaphylactoid reactions were observed in patients receiving ACE inhibitors during desensitizing therapy (for example, by venom of Hymenoptera insects). Such reactions could be prevented by the temporary withdrawal of the ACE inhibitor, but with occasional resumption of treatment the reactions could develop again. As in the case of other beta-blockers, bisoprolol can increase both the sensitivity to allergens, and the severity of anaphylactic reactions. Treatment with epinephrine (adrenaline) does not always produce the expected therapeutic effect.
Neutropenia / agranulocytosis / thrombocytopenia / anemia
In patients receiving ACE inhibitors, cases of neutropenia / agranulocytosis, thrombocytopenia and anemia have been described. In patients with normal renal function and in the absence of other aggravating factors, neutropenia develops rarely. Perindopril should be used with extreme caution in patients with systemic connective tissue diseases receiving immunosuppressants, allopurinol or procainamide, or a combination of these risk factors, especially if there is a history of renal dysfunction.Some of these patients developed severe infections, in some cases not responding to intensive antibiotic therapy. When prescribing perindopril to such patients, it is recommended to periodically check the white blood cell count and instruct patients to tell the doctor about any signs of infectious diseases (eg, sore throat, fever).
Bronchospasm (bronchial asthma, obstructive airway disease)
With bronchial asthma and other chronic obstructive pulmonary diseases, concomitant treatment with bronchodilators should be performed. Sometimes, when using beta-blockers in patients with bronchial asthma, respiratory tract resistance may increase, so an increase in the dose of beta2-adrenomimetics may be required.
Patients with diabetes mellitus
It is recommended that Prestilol® be given with caution in patients with diabetes mellitus who have significant fluctuations in blood glucose levels. Symptoms of hypoglycemia can be masked by the effects of beta-adrenoblockers.
Strict diet
It is advisable to use caution when treating patients who follow a strict diet / fast.
Occlusion diseases of peripheral arteries
When taking beta-blockers, there may be a worsening of symptoms, especially at the initial stages of treatment.
Anesthesia
In patients undergoing general anesthesia, beta-blockers reduce the incidence of arrhythmias and myocardial ischemia during the initial phase of anesthesia and intubation, and also in the postoperative period. Currently, it is recommended to continue therapy with beta-blockers in the perioperative period. An anesthesiologist should be informed of the use of beta-blockers by the patient due to possible drug interactions leading to bradyarrhythmias, weakening of the reflex tachycardia and reduce the reflex ability to compensate for the effects associated with blood loss. If before surgery it is necessary to cancel beta-blocker therapy, this should be done gradually and the cancellation is completed approximately 48 hours before anesthesia.
In patients who are scheduled to undergo extensive surgery or use of anesthesia medications that cause arterial hypotension,The use of perindopril can block the formation of angiotensin II against the background of compensatory release of renin. Treatment should be discontinued one day before surgery. With the development of arterial hypotension by this mechanism, BP should be maintained by replenishing the BCC.
Psoriasis
Patients with psoriasis or having a history of psoriasis may be prescribed beta-blockers only after a thorough assessment of the benefit / risk ratio.
Pheochromocytoma
Patients with a confirmed or suspected pheochromocytoma, bisoprolol should always be prescribed only in combination with an alpha-adrenergic blocker.
Hyperthyroidism
Symptoms of hyperthyroidism may be masked against the background of bisoprolol treatment.
Pregnancy
An alternative hypotensive drug with an established safety profile for use during pregnancy should be scheduled for pregnancy planning, except when ACE inhibitor therapy is considered necessary. When pregnancy is detected, treatment with ACE inhibitors should be stopped immediately and, if necessary, an alternative antihypertensive therapy (seesections "Contraindications" and "Use during pregnancy and during breast-feeding").
Heart failure
Experience with bisoprolol in the treatment of heart failure in patients with the following diseases and conditions is absent:
- type 1 diabetes mellitus,
- severe renal dysfunction,
- severe violations of the liver.
- restrictive cardiomyopathy.
- congenital heart diseases,
- hemodynamically significant organic lesions of the heart valves.
- myocardial infarction, transferred in the last 3 months.
Depression
It is recommended to stop therapy with Prestilol® in the development of depression.
