Edema of the legs is a nuisance that is familiar to so many people. Like any other edema, they require complex treatment, a prominent place in which diuretic drugs occupy. However, not all diuretics for edema of the legs are equally effective. Let's try to understand the secrets of their application.
Diuretic for edema: anatomy of the problem
To understand the reason for the effectiveness of diuretic appointment in edema, it is necessary to have an idea of what constitutes the edema itself.
As you know, the supply of oxygen and nutrients to all tissues of the human body is responsible for blood. Therefore, it constantly moves through the vessels, where it is pumped by the heart. Reaching the smallest blood vessels - capillaries - the blood comes into contact with the cells.
This "contact" is due to the fact that the blood pressure in the capillaries is higher than in the intercellular space, and therefore, due to the special device of the capillary wall, the liquid part of the blood "seeps" there from the arterial end of the tiny vessel.
Back to the vascular bed from the interstitial space, the fluid comes in because of the reduced pressure in the venous end of the capillary. Normally, the processes of fluid entering the tissue and its reverse absorption (reabsorption) are balanced, balance each other, but when the balance is formed, edema is formed.
Thus, the physical essence of edema lies in the fact that excess fluid accumulates in the tissues. Eliminate these excesses helps nothing more than the appointment of a diuretic in swelling.
Diuretic for edema of the legs: the need for a doctor's consultation
Before starting the fight with excess fluid in the body (including taking a diuretic with swelling of the legs), this problem should be addressed to a doctor. After all, edema is very different: for example, common, i.e. spreading throughout the body, or local, manifested in some limited area (they are just the swelling of the feet).
The presence of edema can even serve as a specific diagnostic sign, since for various diseases, certain locations and characteristics of edema are characteristic. For example, in diseases of joints or ligament damage, edema will correspond to the affected area, and in renal pathology, it is most likely that it attacks the back parts of the legs.
With the use of a diuretic in the swelling of the feet, one should also not hurry up because the reasons for this problem are also very many. This can be excessive physical activity, and long standing (for example, in sellers, teachers, etc.), and a sedentary lifestyle, and flat feet.
Even a long sitting on low or too soft armchairs, especially with crossed legs, can cause foot swelling. Of course, in this case, observance of a reasonable alternation of rest and exercise, normalization of the motor regime and adequate orthopedic correction will completely replace the drugs!
On the other hand, swelling of the legs can signal a serious illness - varicose veins, lymph flow in the subcutaneous tissue and skin, kidney or heart failure, and a number of other diseases that require medication. In this case, the use of a diuretic for edema usually enters a complex treatment.
Diuretic for edema of the legs: different drugs - different actions
You do not need to be an expert to understand: in the case when the cause of edema is a serious disease, one drug can not do. In this case, the doctor must take into account the specific features of drug interactions. The latter task would be incomparably more difficult if, by relieving the patient's body of excess fluid (that is, prescribing a diuretic for edema), the doctor did not have a definite choice of these important medicines.
Yes, not all diuretics are the same. Among them are loop and thiazide, and also potassium-sparing drugs. Features of their action and "behavior" in the body help the doctor choose the medicine that best suits a particular patient.
Diuretics with the fastest and thus is short enough action - are loop diuretics. Therefore, they are most often referred to when talking about the use of a diuretic in edema.
Diuretic for edema of the legs: Furosemide (Lasix)
The most famous "old-timer" in this class of diuretics is Furosemide, which in many countries has been prescribed for several decades in the treatment of heart failure, renal and hepatic edema.
Alas, this "well-deserved" medicine is inherent in a number of serious shortcomings. The most important of these is that furosemide activates the production of a number of hormones (angiotensin II, aldosterone and norepinephrine), which contribute to the development of a specific change in the heart muscle - myocardial hypertrophy.
Therefore, in cases where a fast diuretic for swelling should be taken for a long time, there is a need to choose another loop diuretic.
Diuretic for edema of the legs: Torsemide (Torasemide)
From the above-mentioned deficiencies, Torsemide (Torasemide) is eliminated. The active substance of this drug is torsemide, which has a number of advantages over other loop diuretics, which make it an optimal choice of a diuretic for swelling.
Take, for example, the fact that, according to various studies, the effectiveness of Torsemide (Torasemide) is 2.5-5 times higher than that of furosemide (depending on the type of pathology), that is, the daily dose is only 5-10 mg per day against 20-40 mg of furosemide! In addition, Torsemide is better absorbed in the intestine, its distribution in the body almost does not change depending on the intake of food, it does not develop resistance (refractory) in chronic heart failure.
There is another indisputable advantage in Torsemide, which is especially evident when it is necessary to administer large doses of a diuretic or several diuretics with different mechanisms of action, for example, loop and thiazide. In this case, a significant loss of valuable trace elements occurs, hypokalemia develops. And the use of torsemide significantly reduces the loss of potassium and magnesium. In addition, the drug does not "wash away" and calcium, which is especially important for older people at risk of osteoporosis.
And, finally, Torsemide is the only one of the group of torsemides that is produced from the original raw material of the developer of this drug, the Swiss company ROCHE. At the same time, its price is even lower than the price of drugs produced from non-original (not branded) raw materials. All these advantages allow to consider Torsemide the optimal choice of a diuretic for edema of the legs, especially those caused by cardiovascular diseases.
