Arterial hypotension
A marked decrease in blood pressure with the development of clinical symptoms can be observed in patients with a decrease in the volume of circulating blood and / or sodium content due to diuretics, fluid loss or other reasons, for example, increased perspiration, prolonged vomiting and / or diarrhea. Preferably, the recovery of fluid and / or sodium loss is performed prior to the initiation of therapy with the Equator® preparation.
It is necessary to monitor BP after taking the initial dose. Similar conditions apply to patients with ischemic, heart disease or cerebrovascular disease, in whom a marked decrease in blood pressure can lead to myocardial infarction or stroke.
Aortic and mitral stenosis
Like all vasodilators, Equator® should be administered with caution to patients with obstruction of the left ventricular outflow tract and stenosis mitral valve.
Impaired renal function
In some patients with arterial hypertension without pronounced manifestations of renovascular diseases, an increase in the concentration of serum creatinine and urea was observed, in most cases minimal or transient, more pronounced with concurrent administration of an ACE inhibitor and a diuretic.This is most typical for patients with a history of kidney disease.
To determine the optimal maintenance dose, the dosage regimen should be determined individually, using separately lisinopril and amlodipine, with simultaneous monitoring of kidney function. Equator® is indicated only to those patients, in which the optimal maintenance dose of lisinopril and amlodipine is titrated to 10 and 5 mg, respectively.
In the case of a decrease in kidney function, the preparation of Equator® should be discontinued and replaced by monotherapy with drugs in adequate doses. In addition, a dose reduction or elimination of diuretics may be required.
Angioedema
Angioedema of the face, extremities, lips, tongue, vocal folds and / or larynx was recorded in patients taking ACE inhibitors, including lisinopril. In these cases, the preparation of Equator® should be discontinued immediately and the patient should be carefully monitored until the symptoms disappear completely.
Edema of the face, lips and extremities usually passes by itself, nevertheless, for reduce the severity of symptoms should use antihistamines. Angioedema, accompanied by swelling of the larynx, can lead to death.If you detect edema of the tongue, pharynx or larynx, which are the cause of airway obstruction, emergency measures should be urgently started. The proper measures include: the use of 0.1% epinephrine (adrenaline) solution subcutaneously in a dose of 0.3 to 0.5 mg or 0.1 mg intravenously slowly, followed by the use of glucocorticosteroids (intravenously) and antihistamines and simultaneous monitoring of life- important functions.
Patients taking ACE inhibitors rarely had angioneurotic edema of the intestine. These patients complained of abdominal pain (with or without nausea and vomiting); in some cases of a previous angioedema, the face was not observed, and the activity of C-1 esterase was within normal limits. Angioedema of the intestine is diagnosed by computer tomography of the gastrointestinal tract, or after ultrasound, or in surgical intervention; symptoms disappeared after discontinuation of the ACE inhibitor. When performing differential diagnosis of abdominal pain in patients taking ACE inhibitors, you should also consider angioedema of the intestine.
Anaphylactic reactions in patients on hemodialysis
In patients who underwent hemodialysis through a polyacrylonitrile membrane (eg, AN-69®) and who simultaneously received ACE inhibitors, cases of anaphylactic shock have been reported, so it is necessary to avoid this combination. Patients are recommended to use either another type of dialysis membrane, or an antihypertensive drug of another pharmacotherapeutic group.
Anaphylactic reactions in patients during apheresis of low-density lipoproteins (LDL)
Rarely in patients who received ACE inhibitors during the apheresis of LDL with dextran sulfate, life-threatening anaphylactic reactions developed. Such reactions were prevented by abolishing the administration of ACE inhibitors prior to each apheresis procedure.
Desensitization from aspen or bee venom
Anaphylactic reactions developed in patients who took ACE inhibitors with desensitization of Hepaticoptera (eg, wasps or bees), such life-threatening situations can be avoided with the timely withdrawal of ACE inhibitors.
Effects on the liver
In rare cases, the administration of ACE inhibitors was accompanied by a syndrome,which began with cholestatic jaundice or hepatitis and grew into fulminant liver necrosis and, in several cases, resulted in death. The mechanism of this syndrome is unclear. Patients who receive Equator® and who develop jaundice or have an increase in activity of "liver" enzymes should cancel the drug, followed by monitoring their condition.
Liver failure
In patients with impaired hepatic function, the half-life of amlodipine is longer. At the moment, recommendations on the dosage regimen have not been developed, and therefore this medication should be administered with caution, having previously determined the expected benefit and the potential risk of treatment.
Neutropenia / agranulocytosis
In rare cases, neutropenia, agranulocytosis, thrombocytopenia and anemia have been reported in patients receiving ACE inhibitors. In patients with normal renal function and in the absence of other aggravating factors, neutropenia is rare. Neutropenia and agranulocytosis are reversible and disappear after the withdrawal of the ACE inhibitor. Equator® should be used with extreme caution in patients with systemic connective tissue diseases, with immunosuppressive therapy,during treatment with allopurinol or procainamide or a combination of these aggravating factors, especially in the presence of a previous impairment of kidney function. Some of these patients developed serious infectious diseases, in which, in several cases, no response to antibiotic treatment was received. Periodically, in such patients during the treatment with the Equator® drug, it is recommended to conduct laboratory tests (blood count with calculating the leukocyte formula), and also to warn them about the need to report the appearance of the first signs of an infectious disease.
Cough
Cough was often recorded during the use of ACE inhibitors. As a rule, cough is unproductive, persistent and stopped after the drug was discontinued. With a differential diagnosis of cough, one must also consider the cough caused by the use of ACE inhibitors.
Surgery / general anesthesia
Patients undergoing extensive operative intervention or during general anesthesia with drugs leading to hypotension, lisinopril can block the formation of angiotensin II after compensatory release of renin.If arterial hypotension develops, probably as a result of the above mechanism, it is possible to correct the increase in the volume of circulating blood.
Elderly patients
Older patients with impaired renal function should be corrected for the dose of the drug Equator®.
Hyperkalemia
In some patients who received ACE inhibitors, an increase in the content potassium in the blood serum. The risk group for the development of hyperkalemia is patients with renal failure, diabetes, acute cardiac insufficiency, dehydration, metabolic acidosis or with simultaneous intake of potassium-sparing diuretics, potassium-containing food additives, potassium-containing salt substitutes or any other drugs that lead to an increase potassium content in serum (eg, heparin). If it is necessary to simultaneously take the above drugs, you need to monitor the content of potassium in the blood serum.
Patients with low body weight, patients of low growth and patients with severe a violation of liver function may require a dose reduction.
Equator® does not have any adverse effect on the metabolism and lipids of blood plasma and can be used in the treatment of patients with bronchial asthma, sugar diabetes and gout.
During the treatment, it is necessary to control the mass of the bodies with observation by the dentist (for prevention of soreness, bleeding and gingival hyperplasia).
