In this sense, Losartana acts by controlling the change in pressure and can be used alone or in conjunction with a diuretic medication (such as Hydrochlorothiazide).
In addition to treating hypertension, it can also be indicated for the treatment of heart failure, renal protection in patients with type 2 diabetes and cases of proteinuria (elimination of protein in the urine due to renal complication).
It is also used to reduce the risk of cardiovascular morbidity and mortality in hypertensive patients with left ventricular hypertrophy – an increase in the thickness of the heart’s ventricles.

hypotension (drop in pressure) in the first hours. This allows for single administration.

What is the medicine Losartana for?

What is the effect of losartan?
Losartan is categorized as an angiotensin II receptor
antagonist (determinant of the pathophysiology of hypertension). In this sense, the medication works by dilating blood vessels to facilitate the pumping of blood from the heart to the rest of the body.
That’s because angiotensin II normally narrows blood vessels. Then, the treatment with Losartana acts for the vessels to relax.
With this, it helps to reduce high blood pressure and, in patients with heart failure, assists in the better functioning of the heart. In addition, because of its action, it also decreases the risk of heart disease and blood vessels (such as stroke) in patients with high blood pressure and left ventricular hypertrophy.
According to the directions on the label, this medication can also help protect the kidneys in cases of type 2 diabetes and proteinuria (loss of protein in the urine due to impaired kidneys).
Does Losartan Potassium have a diuretic effect? Do you lose weight?
Although Losartana works by lowering blood pressure, as well as diuretic drugs, it does not increase the elimination of fluids. That is,
it has no diuretic effect .
However, experts often indicate the use of a diuretic medication with Losartana, such as Hydrochlorothiazide . What is done in order to enhance the antihypertensive effects.
Anyway, the use of medication does not lose weight (with or without a diuretic). This is because even substances that aid the functioning of the urinary system do not provide weight loss.
Whereas, in these cases, what happens is only the greatest elimination of fluids and not of body fat. So, even if the person feels the swelling decrease, it does not correspond to a real weight loss.
It is worth mentioning, however, that in some
isolated cases the use of Losartana can cause a feeling of bloating as a side effect.

Why take Losartan and Hydrochlorothiazide?
The use of Losartana is indicated for the treatment of people with high blood pressure. However, it is not uncommon to recommend joint use with Hydrochlorothiazide (
diuretic medication ). Thus, the combination of these remedies is made in order to potentiate the antihypertensive effects and decrease risks of cardiovascular events.
In this way, Losartana works by blocking angiotensin II (a substance that narrows blood vessels) and causes the vessels to relax. Hydrochlorothiazide, on the other hand, causes the kidneys to eliminate more salt and water.
This is necessary because not only do chemical substances (such as angiotensin) alter the pressure, but external factors such as excessive salt consumption can also cause this dysregulation.
Thus, the use of both medications tends to have greater effects under high blood pressure.
Treatment for hypertension (high blood pressure) is very important to maintain the quality of life of those who suffer from this condition. In addition to preventing more serious problems, such as stroke.
So, if this is your case, always carry out medical follow-up and follow the guidelines.
