Pharmacological properties
The tablet form of Enalapril makes it easier to take it and select the dosage. This drug is considered a “prodrug”: in the process of its hydrolysis, it creates enalaprilat. This substance inhibits ACE.
The mechanism of action is associated with a decrease in the formation of angiotensin II from angiotensin I. This property leads to a decrease in the release of aldosterone. This results in a decrease in peripheral vascular resistance. Both diastolic and systolic blood pressure decrease. The preload on the myocardium decreases.
The drug dilates arterial vessels more than venous ones. During this, there is no increase in heart rate.
Hypotensive effect is better manifested only when a high level of plasma renin is reached. With a reduced renin index, the hypotensive property is poorly expressed. Lowering blood pressure does not affect cerebral circulation. At the same time, blood flow in the vessels of the brain is maintained at the proper level, even at reduced pressure. Tablets can increase renal and coronary blood flow.
With long-term use of tablets, left ventricular myocardial hypertrophy decreases and myocyte hypertrophy decreasesarterial walls of the resistive type. A similar effect of the drug inhibits the progression of left ventricular dilatation and prevents the development of heart failure. The drug reduces platelet aggregation and stimulates myocardial blood supply. Has a diuretic effect.
After taking the pills, the hypotensive effect appears within an hour. The most powerful antihypertensive property of the drug appears after 4-6 hours. The action of the tablets lasts a day. A certain part of patients need long-term therapy, lasting from six months, to normalize blood pressure.
After oral administration of the drug, up to 60% of the active substance is absorbed. Food does not affect the degree of absorption of the drug. 50% of the drug binds to plasma proteins. "Enalapril" is metabolized in the liver quickly enough. This creates an active metabolite of enalaprilat. It is considered a more effective ACE inhibitor than the active ingredient enalapril. The highest concentration of enalapril in the blood is observed after an hour, enalaprilat - after three hours. Easily and without any problems, enalaprilat passes through histohematogenous barriers. The exception is the blood-brain barrier. A small part of the drug passes into the placenta and passes into breast milk.
The half-life of the drug is eleven hours. About 60% of the drug is excreted by the kidneys, 33% is excreted through the intestines.

Which is better - Enalapril or analogues?
Some analogues of Enalapril are similar betweenthemselves in composition and practically do not differ in the mechanism of action. Other substitutes have a completely different composition, but act on the body in a similar way and belong to the same group of drugs as Enalapril. Below are some comparisons.

Between "Enap" and "Enalapril" differences are minimal. The first drug has a more extensive range of dosages, including tablets of 2.5 ml. Therefore, when prescribing small doses, it is more convenient to take it. Otherwise, the effect of the drugs is similar, although patient reviews claim that Enap is more effective than Enalapril.
The drugs "Captopril" and "Enalapril" belong to the same pharmaceutical group, but their action is different from each other. "Captopril" acts quickly and for a short time. Suitable only for the relief of a hypertensive crisis. And unlike Enalapril, it is not prescribed for continuous use, but is used from time to time.
Enalapril and Enalapril N are slightly different from each other. They have the same analogues and substitutes. But the second drug is considered better, as it contains the diuretic component hypothiazide. Because of what it works faster and more efficiently.
