Simultaneous use of Vazolong® H with preparations containing aliskiren, or with ARA II, leading to a double blockade of RAAS, is not recommended due to the risk of excessive reduction in blood pressure, the development of hyperkalemia and impaired renal function.
Simultaneous use of Vazolong® H with preparations containing aliskiren, in patients with diabetes mellitus and / or renal insufficiency with a CK of less than 60 ml / min is contraindicated (see the sections "Contraindications", "Interaction with other drugs").
Simultaneous use with ARA II in patients with diabetic nephropathy is contraindicated (see the sections "Contraindications", "Interaction with other drugs").
Angioedema
In the treatment of ACE inhibitors, mainly after the first dose, cases of angioedema have been observed. With the development of angioedema during therapy with an ACE inhibitor, immediate discontinuation of its use is required. Angioedema with involvement of the larynx can lead to death. In case of edema of the face, extremities, lips, tongue or vocal cords and especially the development of breathless breathing, stop taking Vazolong® H and immediately begin treatment aimed at stopping angioedema.
In cases where the edema is localized on the face and lips, this condition is usually resolved without treatment, however, antihistamines can be used to relieve symptoms. If swelling to the tongue, vocal cords or throat is spread, airway obstruction may occur, in such cases it is necessary to begin promptly appropriate treatment (including immediate subcutaneous or slow intravenous injection of epinephrine (adrenaline) under ECG and blood pressure control). Recommended hospitalization for at least 12-24 hours and discharge from the hospital only after complete relief of symptoms of angioedema.
Angioedema of the small intestine
Patients receiving ACE inhibitors reported the development of angioedema of the small intestine, which manifested itself in abdominal pain (with or without nausea or vomiting), while in some cases angioedema was observed simultaneously. The diagnosis is established using computed tomography of the abdominal cavity, ultrasound, or at the time of surgery. Symptoms of angioedema of the intestine passed after the cessation of the use of an ACE inhibitor.
Acute myopia and secondary closed angle glaucoma
Hydrochlorothiazide is a sulfonamide derivative. Sulfonamide and sulfonamide derivatives can cause idiosyncrasy reactions leading to the development of transient myopia and acute closed-angle glaucoma, the symptoms of which are acute reduction in visual acuity or eye pain. They usually occur within a few hours to several weeks after starting the drug. In the absence of treatment, acute closed-angle glaucoma can lead to persistent loss of vision. It is necessary to stop taking the drug as soon as possible. Emergency medical or surgical treatment may be required if the intraocular pressure remains uncontrolled. Risk factors for the development of acute myopia or secondary closed-angle glaucoma are anamnestic indications of allergy to sulfonamide derivatives or penicillins.
Cough
When taking Vazolong® H, there may be a "dry" cough that usually disappears after the drug is discontinued. Such a probability must be taken into account when conducting a differential diagnosis of cough.
Anaphylactoid reactions to ACE inhibitors
With the use of ACE inhibitors, life-threatening, rapidly developing anaphylactoid reactions have been described, sometimes up to the development of shock during hemodialysis using certain high-flow membranes (for example, polyacrylonitrile membranes) (see also membrane manufacturers instructions). It is necessary to avoid joint use of Vazolong® H and this type of membranes, for example, for urgent hemodialysis or hemofiltration. In this case, it is preferable to use other types of membranes or to exclude the use of ACE inhibitors.
Similar reactions were observed in the apheresis of low-density lipoproteins using dextran sulfate. These reactions could be avoided with the temporary cessation of therapy with an ACE inhibitor before each next apheresis. Antihistamines are ineffective for the removal of these reactions.
Separate reports of patients with prolonged life-threatening anaphylactoid reactions arising during desensitizing treatment with bee venoms, wasps, and the like were obtained. In some patients, these reactions were avoided with a preliminary temporary withdrawal of ACE inhibitors for a period of at least 24 hours.
Reactions of hypersensitivity to hydrochlorothiazide do not depend on the presence in the history of allergy or bronchial asthma.
Arterial hypotension
After ramipril, usually after the first or second dose, or after increasing the dose, it is possible to develop arterial hypotension, which is most likely in patients whose bcc has been reduced as a result of diuretic therapy, limited intake of table salt with food, dialysis, diarrhea, vomiting or profuse sweating.
It is generally recommended that dehydration, hypovolemia and hyponatremia be corrected before starting the use of the drug (however, in patients with heart failure, BCC replacement should be carried out with great caution, since there is a risk of decompensation due to excessive volume loading).
Transient excessive decrease in blood pressure is not a contraindication for the continuation of therapy after stabilization of blood pressure. In the case of repeated excessive decrease in blood pressure should reduce the dose or cancel the drug.
Patients with activation of RAAS
In conditions in which the activation of RAAS takes place and / or the renal function depends on its activity (see Fig."With caution"), with the inhibition of ACE, there is an increased risk of a marked decrease in blood pressure and impaired renal function. Therefore, in such cases, at the beginning of the treatment or at the beginning of the increase in the initial dose, BP control is required before the time when no further BP reduction is expected.
In patients with severe chronic heart failure (including those accompanied by renal insufficiency), therapy with an ACE inhibitor may cause an excessive decrease in blood pressure and be accompanied by oliguria and / or progressive azotemia with acute renal failure, up to a lethal outcome. In such patients, the initiation of treatment with Vazolong® H or its continuation should be carried out only after taking measures against a sharp decrease in blood pressure and impaired renal function.
Patients, for which an excessive decrease in blood pressure represents a particular danger
Particular danger is the excessive reduction in blood pressure for patients with coronary heart disease or with severe atherosclerosis of the cerebral vessels, since in this case, it is possible to develop a myocardial infarction or stroke (see the section "With caution").Such patients are subject to strict observation at the beginning of treatment and with an increase in the dose of the drug.
Patients with dehydration
All patients should be warned that dehydration due to increased sweating (including in hot weather or physical exertion), vomiting, diarrhea can lead to excessive blood pressure lowering, and in these cases the question of the applied doses of ramipril and hydrochlorothiazide should be decided by the doctor.
Alcohol intake during treatment
During treatment with Vazolong® H, alcohol is not recommended (see section "Interaction with other drugs").
In case of excessive reduction in blood pressure, it is necessary to put the patient in a horizontal position with raised legs, and, if necessary, start an intravenous infusion of 0.9% sodium chloride to replenish the BCC.
Surgery and general anesthesia
Before surgery (including dental), it is necessary to alert the surgeon / anesthesiologist about the use of ACE inhibitors. If arterial hypotension develops during general anesthesia, it can be corrected by replenishing the BCC.
Thiazides can enhance the effects of tubocurarine.
It is recommended that treatment with ACE inhibitors, including ramipril, was discontinued (if possible) one day before surgery.
Primary hyperaldosteronism
Patients with primary hyperaldosteronism usually do not respond to antihypertensive drugs acting through inhibition of RAAS. Therefore, the drug Vazolong® H is not a drug of choice for the treatment of primary hyperaldosteronism.
Hematological control
When taking the drug Vazolong® H, it is recommended to control the number of leukocytes to detect possible leukopenia. Regular monitoring is recommended at the beginning of treatment and in patients with impaired renal function, systemic connective tissue diseases (systemic lupus erythematosus, scleroderma) or in patients receiving other drugs capable of altering the picture of peripheral blood (see "Side effect", "Interaction with other drugs "). When symptoms appear due to leukopenia (eg, fever, enlargement of lymph nodes, tonsillitis), urgent monitoring of the picture of peripheral blood is needed.In case of signs of bleeding (the smallest petechiae, red-brown rashes on the skin and mucous membranes), it is also necessary to control platelets in the peripheral blood.
Control of liver function
A complete liver function test and other studies should be performed to identify symptoms that are suspicious of the disorder: flu-like symptoms that occur in the first weeks or months of treatment (such as fever, malaise, muscle pain, skin rash, or adenopathy, indicating hypersensitivity reactions ), abdominal pain, nausea or vomiting, loss of appetite, jaundice, pruritus, or other unexplained symptoms. If liver function is confirmed, discontinue taking Vazolong® H and, if necessary, prescribe appropriate treatment.
In patients with impaired hepatic function or with progressive liver diseases, the use of thiazide diuretics requires caution, since in such patients even minimal disturbances of the water-electrolyte balance can provoke a hepatic coma.
Controlled clinical trials involving patients with cirrhosis and / or liver dysfunction are not available.With extreme caution should be used preparation Vazolong® H in patients with pre-existing liver disorders, which prior to the use of the drug should determine the status of liver function and strictly monitor it during treatment.
Control of kidney function
Due to the suppression of RAAS activity in predisposed patients, renal function may worsen, the risk of which increases with the simultaneous use of diuretics.
It is recommended to closely monitor kidney function, especially in the first weeks of treatment and in the following patient groups:
- patients with heart failure;
- patients with renovascular diseases, including hemodynamically significant unilateral renal artery stenosis (in such patients, even a slight increase in serum creatinine concentrations may be a manifestation of a unilateral reduction in renal function);
- patients with impaired renal function;
- patients after kidney transplantation.
In patients with impaired renal function, special care is required when using the drug Vazolong® H, and in these cases, smaller doses of the drug are used (see section "Method of administration and dose").
Hydrochlorothiazide can promote or enhance azotemia. Cumulative effects of the drug are possible in patients with impaired renal function. If increasing azotemia and oliguria develop during treatment of a serious progressive kidney disease, diuretic therapy should be discontinued.
Inadequate experience is accumulated in the use of the drug in patients with severe renal impairment (creatinine clearance less than 30 ml / min) and in patients on hemodialysis.
Control of laboratory indicators
When therapy with the drug Vazolong® H, it is necessary to control the content of sodium, potassium, calcium, uric acid in the blood serum and glucose in the blood. Patients with impaired renal function, with violations of the water-electrolyte balance require regular monitoring of potassium in the blood serum.
Other precautions
Thiazide diuretics can reduce the concentration in the blood of protein-bound iodine without causing signs of thyroid dysfunction.
Thiazide diuretics can cause a temporary and small increase in serum calcium in the absence of known calcium metabolism disorders.Expressed hypercalcemia may indicate latent hyperparathyroidism. Before analyzing the function of the parathyroid glands, thiazide diuretics should be discarded.
Risk factors for the development of hyperkalemia include renal failure, diabetes mellitus, and simultaneous use of drugs for the treatment of hypokalemia or other drugs capable of increasing serum potassium (see "Interactions with Other Drugs"). Patients should be advised not to use salt substitutes containing potassium, without first consulting a physician.
It should be borne in mind that with the use of hydrochlorothiazide, a positive result is possible with doping control.
In the event of a syncopal condition, it is necessary to stop taking the medication and inform the doctor about it.
