When the episode of unstable angina develops (significant or not) during the first month of therapy with the drug Perindopril needs to assess the benefit / risk ratio for therapy with this drug.
In the case of arterial hypotension necessary to give a patient a horizontal position with the raised feet, and if necessary to administer intravenously to increase the 0.9% sodium chloride solution was bcc. Transient arterial hypotension is not a contraindication for further therapy. After the recovery of the bcc and AD treatment can be continued under the condition of careful selection of the dose of the drug. In some patients with CHF and normal or low blood pressure during drug therapy Perindopril there may be an additional reduction in blood pressure. This effect is expected and usually not is the basis for drug cancellation. If arterial hypotension accompanied by clinical manifestations, a dose reduction or drug cancellation may be required Perindopril. Impaired renal function In patients with renal insufficiency (KC less than 60 ml / min) the initial dose of the drug Perindopril should be selected in accordance with the QC (see section "Method of administration and dose") and then - depending on the therapeutic response. For such patients, regular monitoring of serum potassium and serum creatinine is necessary.
In some patients with hypertension, in the presence of previously not revealed renal failure, especially with concomitant therapy with diuretics, there was a small and a temporary increase in the concentration of urea and creatinine in the blood serum. In this case, a dose reduction preparation Perindopril and / or cancellation of a diuretic.
Patients on hemodialysis
In patients on dialysis using high-flow membranes and receiving concurrent with ACE inhibitors, several cases of persistent, menacing life of anaphylactic reactions. If necessary of hemodialysis is necessary use a different type of membrane.
Kidney Transplantation
Experience of application preparation Perindopril In patients with recent renal transplantation there is no kidney.
Hypersensitivity, angioedema Rarely in patients taking ACE inhibitors, in t.ch. perindopril, angioneurotic edema of the face, limbs, lips, tongue, vocal cords and / or larynx developed. This condition can develop at any time of treatment. When The development of angioedema be discontinued immediately, patient must be under medical supervision before complete extinction symptoms.
Angioedema of the lips and face usually does not require treatment; for decreasing severity of symptoms can apply antihistamines facilities.
Angioedema, swelling of the tongue, vocal cords or larynx can lead to death. With the development of angioedema, immediately subcutaneously epinephrine (adrenalin) and ensure airway patency. ACE inhibitors often cause angioedema in the Negro race. Patients with an angioneurotic edema in a history not associated with the use of ACE inhibitors may be prone to high risk development of angioedema, with an ACE inhibitor.
Anaphylactoid reactions during the procedure of apheresis of low-density lipoproteins (LDL-apheresis)
In patients with the appointment of inhibitors ACE on the background of the procedure of LDL-apheresis with dextran-sulfate absorption, in rare cases, the development of anaphylactic reaction.
A temporary withdrawal of an ACE inhibitor is recommended before each apheresis procedure. Anaphylactic reactions at desensitization In patients receiving ACE inhibitors during the course of desensitization (for example, the venom of Hymenoptera), in very rare cases development of menacing
life of anaphylactic
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 there is jaundice during an ACE inhibitor or if there is an increase in activity "hepatic" enzymes, the ACE inhibitor should be immediately discontinued, and the patient should be carefully monitored. It is also necessary to conduct the corresponding examination.
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. A drug Perindopril it is necessary to use with great care in patients with systemic diseases of connective tissue (eg, SLE, 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 may develop severe infections that do not respond to intensive antibiotic therapy. When the drug is administered Perindopril in patients with the above factors, it is recommended that periodically control the number of white blood cells 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 glucose-6-phosphate dehydrogenase, isolated cases of development of hemolytic anemia were noted.
Negroid race
The risk of angioedema development in patients of the Negroid race is higher. Like other ACE inhibitors, perindopril 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 differential diagnosis cough.
Surgery and general anesthesia
In patients whose condition requires extensive surgery 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 surgical intervention therapy inhibitors ACE must be canceled. If the ACE inhibitor can not be canceled, then the arterial hypotension, which develops according to the described mechanism,can be corrected by increasing the 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, decompensated diabetes mellitus and in patients using potassium-sparing diuretics, potassium preparations or other drugs that cause hyperkalemia (eg, heparin). If it is necessary to simultaneously prescribe these drugs, it is recommended that
regularly monitor the potassium content in the blood serum.
Diabetes
In patients with diabetes mellitus taking hypoglycemic agents for ingestion or insulin, in the first few months of therapy with ACE inhibitors it is necessary closely monitor concentration of glucose in the blood.
