Therapy with ACE inhibitors should be started under the control of blood pressure, taking into account the maximum effect of lisinopril after 6-8 hours (with myocardial infarction 8-10 h).
High-risk group development of dangerous adverse reactions are patients with. heart failure (with or without renal insufficiency). In such cases, treatment with lisinopril should be started under the strict supervision of a doctor in a hospital. Similar rules should also be adhered to when assigning patients with coronary heart disease, cerebrovascular insufficiency, in which a sharp decrease in blood pressure can lead to myocardial infarction or stroke.
A marked decrease in blood pressure after taking the first dose of the drug can develop, in particular, in patients with high plasma renin activity (for example, in the presence of diuretic therapy in high doses or congestive heart failure). The pronounced decrease in blood pressure arises with initially reduced volume of circulating blood due to diuretic therapy, diets with restriction of table salt, hemodialysis, diarrhea and vomiting. Before starting treatment with lisinopril, it is necessary to replenish the volume of circulating blood.
Transient arterial hypotension is not a contraindication for taking the next dose of the drug.
With the use of lisinopril in some patients with chronic heart failure with normal or low blood pressure, there may be a decrease in blood pressure, which is not a reason for stopping treatment.
With stenosis of the renal artery (especially with bilateral stenosis, or with stenosis of the single kidney artery), as well as inadequate circulation, due to lack of sodium and / or liquid, the use of lisinopril may lead to an increase in the concentration of urea and creatinine in the blood, impaired renal function, and acute renal failure.
Treatment with lisinopril with acute myocardial infarction spend on a background of standard therapy (thrombolytics, acetylsalicylic acid, beta-blockers). Compatible with intravenous nitroglycerin and transdermal therapeutic system (TTS) nitroglycerin.
Surgery / general anesthesia. With extensive surgical interventions, as well as with the use of other drugs that cause a decrease in blood pressure, lisinopril, blocking the formation of angiotensin II, can cause a pronounced unpredictable decrease in blood pressure. Before surgery, including dental surgery, you should inform the surgeon / anesthesiologist about the use of an ACE inhibitor.
In elderly patients the same dose leads to a higher concentration of the drug in the blood plasma, so special care is required when determining the dose. Angioedema when using ACE inhibitors, including lisinopril, can develop at any stage, treatment. When swelling of the tongue, throat, larynx, airway obstruction with lethal outcome may develop.
If these complaints appear, stop taking the medication immediately and consult a doctor.In such cases, a rapid subcutaneous injection of an adrenaline solution 0.1% (0.3-0.5 ml), the administration of glucocorticosteroids, antihistamines and / or measures to ensure airway patency.
ACE inhibitors often cause the development of angioedema in patients of the Negroid race, than in representatives of other races.
In patients with heart failure, diabetes mellitus, concurrently taking potassium supplements, potassium-containing salt substitutes, potassium-sparing diuretics, or other drugs that increase serum potassium levels (heparin), ACE inhibitors increase the risk of developing hyperkalemia.
Very rarely, with the use of ACE inhibitors, a syndrome that started with cholestatic jaundice or hepatitis was observed and progressed to fulminant necrosis in the liver and (sometimes) with a fatal outcome. The mechanism of development of this syndrome is unknown. When jaundice occurs on the background of the use of the drug or a pronounced, increased activity of "liver" transaminases, the drug should be discontinued and careful monitoring of the patient's condition.
The use of lisinopril as well as all ACE inhibitors may be accompanied by a dry cough that stops when the dose of the drug is lowered or treatment is stopped. Because the potential risk of agranulocytosis can not be ruled out, periodic monitoring of the blood picture is required.
In patients taking ACE inhibitors, during desensitization to the venom of Hymenoptera (bees and wasps), a life threatening anaphylactoid reaction may occur. It is necessary to temporarily stop treatment with an ACE inhibitor before starting the course of desensitization.
Anaphylactoid reactions may occur with simultaneous hemodialysis using high-flow membranes (including AN 69®), as well as during apheresis of low-density lipoproteins with adsorption to dextran sulfate.
It is necessary to consider the possibility of using a different type of membrane for dialysis or another antihypertensive drug.
Patients receiving hypoglycemic agents inside and insulin during the first month of therapy with ACE inhibitors should regularly monitor blood glucose.
Care should be taken when performing physical exercises,hot weather (the risk of dehydration and excessive blood pressure lowering due to a decrease in the volume of circulating blood).
During the period of treatment, it is not recommended to drink alcoholic beverages, since alcohol increases the antihypertensive effect of the drug.
