Symptomatic hypotension
Most often, a marked decrease in blood pressure occurs with a decrease in the volume of circulating blood (BCC), caused by diuretic therapy, a decrease in salt in the diet, dialysis, diarrhea, or vomiting. In patients with chronic heart failure with concurrent renal failure or without it, a marked decrease in blood pressure is possible.
Under the strict supervision of a physician, Lisinopril patients with coronary artery disease, cerebrovascular insufficiency, in whom a sharp decrease in blood pressure can lead to myocardial infarction or to a stroke.Transient arterial hypotension is not a contraindication for taking the next dose of the drug.
When using the drug Lisinopril, in some patients with chronic heart failure, but with normal or low blood pressure, there may be a decrease in blood pressure, which is usually not a reason for stopping treatment.
Before the start of treatment with the drug, if possible, the sodium content should be normalized and / or replenished with BCC. carefully monitor the effect of the initial dose of the drug Lisinopril on the patient.
With bilateral renal artery stenosis and renal artery stenosis of a single kidney, as well as with hyponatremia and / or a decrease in the volume of circulating blood (BCC) or circulatory insufficiency, arterial hypotension caused by taking the drug Lisinopril, can lead to a decrease in kidney function with the subsequent development of reversible (after discontinuation of the drug) acute renal failure.
Data on the use of the drug Lisinopril in patients after kidney transplantation there are no kidneys.
With acute myocardial infarction
The use of standard therapy (thrombolytics, acetylsalicylic acid, beta-blockers). Lisinopril it is possible to use together with intravenous administration or with the use of therapeutic transdermal systems of nitroglycerin.
Stenosis of the aortic estuary / hypertrophic obstructive cardiomyopathy
Lizinopril, like other ACE inhibitors, should be administered with caution to patients with obstruction of the left ventricular outflow tract (stenosis of the aortic estuary, hypertrophic obstructive cardiomyopathy).
Hyperkalemia
During treatment with ACE inhibitors, including lisinopril, hyperkalemia may develop. Risk factors for hyperkalemia include renal failure (eg, diabetic nephropathy), advanced age, diabetes mellitus, certain concomitant conditions (decreased BCC, acute heart failure in decompensation, metabolic acidosis), simultaneous use of potassium-sparing diuretics (spironolactone, eplerenone, triamterene, amiloride), as well as preparations of potassium or potassium-containing salt substitutes and the use of other drugs that increase the level of potassium in the blood plasma (for example, heparin).If it is necessary to simultaneously take the above drugs, you need to monitor the potassium content in the blood serum.
Surgery / general anesthesia
With extensive surgical interventions, as well as with the use of other means that cause a decrease in blood pressure, Lisinopril, blocking the formation of angiotensin II, can cause a pronounced unpredictable decrease in blood pressure.
Hypoglycemic drugs
With the simultaneous use of ACE inhibitors and insulin, as well as hypoglycemic drugs for oral administration, hypoglycemia may develop. The greatest risk of development of hypoglycemia is observed during the first two weeks of combined therapy, as well as in patients with renal impairment. Patients with diabetes require careful monitoring of the glycemic profile, especially during the first month of therapy.
In elderly patients, the same dose leads to a higher concentration of the drug in the blood, therefore special caution is required when determining the dose.
Because the potential risk of agranulocytosis can not be ruled out, periodic monitoring of the blood picture is required.
When using the drug in dialysis with polyacryl-nitrile membranes, anaphylactic shock can occur. therefore, either a different type of membrane for dialysis or the prescription of other antihypertensive agents is recommended.
Double blockade of RAAS
Arterial hypotension, fainting, stroke, hyperkalemia and renal dysfunction (including acute renal failure) have been reported in susceptible patients, especially when used with medications that affect this system. Therefore, a double blockade of RAAS due to a combination of an ACE inhibitor with ARA II or aliskiren is not recommended.
Hypersensitivity / angioedema
In rare cases, against the background of therapy with ACE inhibitors, angioedema develops in 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 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 at the time of surgical intervention.Symptoms disappear after the cessation of the use of ACE inhibitors. In patients with abdominal pain taking ACE inhibitors, the differential diagnosis should take into account the possibility of angioedema edema development.
Neutropenia, agranulocytosis, thrombocytopenia, anemia
Against the background of taking ACE inhibitors, neutropenia, agranulocytosis, thrombocytopenia and anemia can occur. In patients with normal renal function and in the absence of other aggravating factors, neutropenia develops rarely. With special care, lisino-pril should be used in patients with systemic connective tissue diseases, when immunosuppressants, allopurino-l or procainamide are used, especially in patients with impaired renal function.
Ethnic differences
Lizinopril and other ACE inhibitors are less effective in patients of the Negroid race, due to the prevalence of patients with hypertension with low renin activity. In patients of the Negroid race angioneurotic edema with lisinopril is more common than in patients of other races.
