Dosage and administration
The drug is taken orally, regardless of the meal, preferably at the same time of day. pills should be taken with a small amount of liquid.
The initial dose is from 5 to 20 mg 1 time / day, depending on the severity of hypertension. With mild arterial hypertension, the recommended initial dose is 5-10 mg / day.
In patients with pronounced activation of the RAAS (for example, with renovascular hypertension, loss of electrolytes and / or dehydration, decompensation of heart failure or severe arterial hypertension), an excessive decrease in blood pressure at the beginning of treatment is possible. In such situations, it is recommended to begin therapy with a low initial dose of 5 mg / day or less, under the supervision of a physician.
Prior diuretic therapy in high doses may lead to dehydration and an increase in the risk of arterial hypotension at the beginning of Enap therapy.®; The recommended starting dose is 5 mg / day. Treatment with diuretics should be stopped for 2-3 days before the start of the use of the drug Enap®. Care should be taken when using the drug Enap®, monitor kidney function and serum potassium.
Usually the maintenance dose is 20 mg 1 time / day.
The dose is selected individually, if necessary, can be increased to a maximum daily dose of 40 mg.
Chronic heart failure and left ventricular dysfunction
The initial dose is 2.5 mg 1 time / day, and the treatment should be started under close medical supervision.
Drug Enap® for the treatment of heart failure, it can be used simultaneously with diuretics and / or beta-blockers, if necessary with cardiac glycosides. In the absence of symptomatic hypotension at the beginning of therapy or after its correction, the dose should be increased gradually (by 2.5-5 mg every 3-4 days) to the usual maintenance dose of 20 mg / day, which is prescribed either once or in 2 doses, in depending on the tolerability of the drug. Dose selection is carried out within 2-4 weeks. The maximum daily dose is 40 mg in 2 divided doses.
Dose in mg / day
1-3 day: 2.5 mg / day * in 1 reception
10 mg in 1-2 doses
Week 3 and 4
20 mg in 1-2 doses
* Special precautions should be observed in patients with impaired renal function taking diuretics.
Given the risk of arterial hypotension and renal failure (observed much less frequently), blood pressure and kidney function should be carefully monitored before and after using Enap®. In patients taking diuretics, the dose of the latter should, if possible, be reduced before starting the administration of Enap®. The development of arterial hypotension after taking the first dose does not mean that arterial hypotension will continue with prolonged use, and does not indicate the need to discontinue the use of the drug.
In patients with impaired renal function should increase the intervals between doses and / or reduce the dose of the drug Enap®.

Use during pregnancy and lactation
Use of the drug Enap®, like other ACE inhibitors, is not recommended in the first trimester of pregnancy. The use of ACE inhibitors, incl. drug Enap®, in the II and III trimesters of pregnancy is contraindicated.
Epidemiological data on the risk of teratogenic effects of ACE inhibitors during pregnancy do not make it possible to draw final conclusions. However, the likelihood of the development of teratogenic effects cannot be excluded. If necessary, the use of ACE inhibitors, the patient must be transferred to therapy with another antihypertensive drug with a proven safety profile for pregnant women.
When pregnancy is confirmed the drug Enap® need to cancel as soon as possible.
Acceptance of ACE inhibitors in the II and III trimesters of pregnancy can cause fetotoxic effects (renal dysfunction, oligohydramnion, delayed ossification of the skull bones) and neonatal toxic effects (renal failure, arterial hypotension, hyperkalemia).
If the patient took an ACE inhibitor in the II and III trimesters of pregnancy, it is recommended to conduct an ultrasound of the kidneys and bones of the fetal skull.
In those rare cases where the use of an ACE inhibitor during pregnancy is considered necessary, periodic ultrasound scans should be performed to evaluate the amniotic fluid index. If an oligohydramnion is detected during an ultrasound, it is necessary to stop taking the drug. Patients and the physician should be aware that oligohydramnios develops with irreversible damage to the fetus. If ACE inhibitors are used during pregnancy and the development of oligohydramnios is observed, then depending on the duration of pregnancy, a stress test, a non-stress test, or determination of the biophysical profile of the fetus may be required to assess the functional status of the fetus.
Newborns whose mothers took ACE inhibitors during pregnancy should be monitored due to possible arterial hypotension. Enalapril, which crosses the placenta, can be partially removed from the blood circulation of a newborn using peritoneal dialysis; in theory, it can be removed by exchange transfusion.
Enalapril and enaprilat are determined in breast milk in trace concentrations, therefore, if necessary, the use of the drug Enap® during lactation, breastfeeding should be discontinued.
Application for violations of the liver
WITH caution the drug should be used in patients with liver failure.
Application for violations of kidney function
In patients with impaired renal function should increase the intervals between doses and / or reduce the dose of the drug Enap®.
WITH caution the drug should be used in patients with bilateral renal artery stenosis or arterial stenosis of a single kidney, after kidney transplantation, renal failure (proteinuria - more than 1 g / day), in patients undergoing hemodialysis.* Enalaprilat is derived from hemodialysis. In the interval between hemodialysis sessions, the dose of the drug should be selected under the control of blood pressure.
Symptomatic arterial hypotension rarely develops in patients with uncomplicated arterial hypertension. Hypotension with all clinical manifestations can be observed after the first dose of Enap® in patients with hypovolemia, as a result of diuretic therapy, salt-free diets, diarrhea, vomiting or hemodialysis. The development of symptomatic hypotension is more likely in patients with severe heart failure due to the use of high-dose diuretics, hyponatremia or impaired renal function. In such patients, treatment should begin under the supervision of a physician, up to an optimal dose adjustment of Enap® and / or diuretic. A similar tactic can be applied to patients with coronary artery disease or cerebrovascular diseases in whom a sharp excessive decrease in blood pressure can lead to the development of myocardial infarction or impaired cerebral circulation.
In the case of the development of severe arterial hypotension, it is necessary to transfer the patient to a horizontal position with a low head and, if necessary, inject the 0.9% sodium chloride solution.
Transient arterial hypotension is not a contraindication for further treatment with Enap®. After stabilization of blood pressure and BCC therapy can be continued.
In some patients with heart failure and normal or low blood pressure, it may be further reduced when taking Enap®. This effect is predictable and is not a reason to discontinue therapy. If arterial hypotension is accompanied by clinical symptoms, the dose should be reduced and / or the diuretic and / or Enap abolished.®.
Aortic or mitral stenosis, GOKMP
Like all vasodilators, ACE inhibitors should be used with caution in patients with valvular obstruction and left ventricular outflow tract hypertrophy. Patients with cardiogenic shock and hemodynamically significant obstruction of the left ventricle should not be prescribed.
In patients with renal insufficiency (CC <80 ml / min (1.33 ml / s)), the initial dose of Enap® should be selected, first of all, taking into account QC and, then, the clinical response to treatment. In such patients, potassium levels and serum creatinine levels should be regularly monitored.
In patients with severe heart failure and kidney disease, including renal artery stenosis, when treated with Enap® possible development of renal failure. Changes were usually reversible after discontinuation of Enap®.
In some patients with arterial hypertension who did not have kidney disease prior to treatment, there was a slight and transient increase in the concentration of urea and creatinine in the blood serum when Enap was used.®. In such cases, it may be necessary to reduce the dose of Enap® and / or diuretic withdrawal.This situation indicates the possibility of latent renal artery stenosis.
In patients with bilateral renal artery stenosis or arterial stenosis of the only functioning kidney with treatment with ACE inhibitors, the risk of arterial hypotension and renal failure is increased. Only insignificant changes in serum creatinine may indicate a decrease in kidney function. In these patients, treatment should begin with small doses under the close supervision of a physician. It is necessary to carefully titrate the dose and monitor kidney function.
Experience with Enap® in patients who have recently undergone kidney transplantation, is absent. Therefore, the treatment of such patients with Enap® Not recommended.
In rare cases, therapy with ACE inhibitors has been accompanied by the development of a syndrome starting with cholestatic jaundice and hepatitis, up to the development of fulminant necrosis of the liver. The mechanism of development of this syndrome is unknown. If jaundice appears or a significant increase in liver enzyme activity, immediately discontinue treatment with an ACE inhibitor, carefully monitor the patient's condition and, if necessary, treat it.
Neutropenia / Agranulocytosis
Patients who used ACE inhibitors described cases of neutropenia / agranulocytosis, thrombocytopenia, and anemia.In patients with normal renal function in the absence of other complications, neutropenia rarely develops. Drug Enap® It should be used with great caution in patients with connective tissue diseases (including systemic lupus erythematosus, scleroderma) who are simultaneously receiving immunosuppressive therapy, Allopurinol or procainamide, as well as with a combination of these factors, especially for existing disorders of renal function. Such patients may develop severe infections that are not susceptible to intensive antibiotic therapy. If patients still take the drug Enap®It is recommended to periodically monitor the number of leukocytes in the blood. The patient should be warned that in the event of any signs of infection, you should immediately consult a doctor.
Hypersensitivity / angioedema
In patients receiving ACE inhibitors, including the drug Enap®, reports of the development of angioedema of the face, extremities, lips, vocal folds and / or larynx at any time after the start of treatment. It should immediately cancel the drug Enap® and observe the patient until symptoms disappear. Even in the presence of edema of the tongue, when there is only difficulty in swallowing without respiratory distress syndrome, patients may need long-term observation, since use of antihistamines and corticosteroids may be insufficient.
Angioedema of the larynx or tongue can be very rarely fatal. Swelling of the tongue, vocal cords or larynx can lead to airway obstruction, especially after a history of airway surgery. In the presence of edema of the tongue, vocal folds or larynx, appropriate therapy is indicated, which may include: subcutaneous injection of a 0.1% solution of epinephrine (adrenaline) (0.3 ml-0.5 ml) and / or measures aimed at restoring the airway patency (intubation or tracheostomy).
The incidence of angioedema is higher among patients of the Negroid race who receive treatment with an ACE inhibitor, than among patients of a different race.
Patients with a history of angioedema that is not associated with ACE inhibitors have an increased risk of developing angioedema when using any ACE inhibitor.
Anaphylactoid reactions in desensitization by hymenoptera venom (Hymenopter)
Patients taking ACE inhibitors during desensitization with hymenoptera poison rarely developed life-threatening anaphylactoid reactions. To prevent such reactions, it is necessary to temporarily stop taking the ACE inhibitor during desensitization procedures.
Anaphylactoid reactions during LDL apheresis
Patients who took ACE inhibitors during apheresis of LDL using dextran sulfate, in rare cases, have developed life-threatening anaphylactoid reactions. The drug should be temporarily replaced by drugs of another group.
Due to the increased risk of anaphylactoid reactions, the drug should not be used in patients on hemodialysis using high-flow polyacrylonitrile membranes (AN69®). If hemodialysis is necessary, it is advisable to use dialysis membranes of another type or antihypertensive drugs of another group.
In patients with diabetes mellitus receiving hypoglycemic drugs for oral administration or insulin, the concentration of blood glucose should be carefully monitored during the first month of treatment with an ACE inhibitor.
When using the drug Enap® a dry, unproductive, long-lasting cough may occur, which disappears after discontinuation of the use of ACE inhibitors, which must be taken into account in the differential diagnosis of cough while using an ACE inhibitor.
Surgical intervention / general anesthesia
Before surgery (including dental procedures) it is necessary to warn the surgeon / anesthesiologist about the use of Enap®. With extensive surgery or general anesthesia using agents that cause arterial hypotension, ACE inhibitors can block the formation of angiotensin II in response to compensatory renin release. If this develops a pronounced decrease in blood pressure, explained by a similar mechanism, it can be adjusted by the introduction of plasma substitutes.
May develop during treatment with ACE inhibitors, incl. Enap®. Risk factors for the development of hyperkalemia are renal failure, advanced age (older than 70 years), diabetes mellitus, some concomitant states (decreased BCC, acute heart failure in the decompensation stage, metabolic acidosis), simultaneous use of potassium-sparing diuretics (spironolactone, eplerenone, triamterene, amiloride), as well as preparations of potassium or potassium-containing substitutes and the use of other drugs that increase the content of potassium in the blood plasma (for example, heparin).
The use of potassium preparations, potassium-sparing diuretics, and potassium-containing food salt substitutes may lead to a significant increase in the serum potassium content, especially in patients with impaired renal function. Hyperkalemia can lead to serious heart rhythm disturbances, sometimes fatal. The simultaneous use of the above preparations should be carried out with caution under the control of the content of potassium in the blood serum.
The simultaneous use of lithium salts and the drug Enap® Not recommended.
Drug Enap®, like other ACE inhibitors, has a less pronounced antihypertensive effect in patients of the Negroid race compared with other races.
Special information on excipients
Drug Enap® contains lactose, so the drug is contraindicated in patients with lactase deficiency, lactose intolerance, and glucose-galactose malabsorption syndrome.
Influence on ability to drive motor transport and control mechanisms
When using the drug Enap® Care must be taken when driving and performing other potentially dangerous types of work that require increased concentration and psychomotor speed (dizziness may develop as a result of a sharp decrease in blood pressure, especially after taking the initial dose of Enap® in patients taking diuretics).
