    1. Trental improves the microcirculation of , makes the blood less viscous. Increases the elasticity of erythrocytes, reduces the level of clotting of platelets, lowers the concentration of fibrinogen, improves the ability of the body to dissolve thrombi.
    2. Promotes the accumulation of adenic acid in the walls of vessels( the lumen in the vessels, due to this substance, increases).It blocks the activity of phosphodiesterase( its excess reduces the elasticity of the vessels).
    3. Relaxes smooth muscle vessels , slightly widens their walls, but does not greatly change the heart rate.
    4. Positively affects the cellular respiration in the tissues of the central nervous system, limbs and kidneys.
    5. Improves the course of the metabolic processes in the central nervous system, electrical conductivity( exchange of pulses in KGM).
    6. When injected with the drug, is stimulated by the flow of blood into the peripheral parts of the limbs.


    What happens when taking the drug?

    Tablets 100, 400 mg

    Taking Trental 100 or 400 orally, the active substance pentoxifylline is absorbed quickly and almost completely. After almost complete absorption, he is involved in the body's metabolic system.

    The person assimilates 19 + -13% of the total preparation. That is a rather high index for the drugs of this group.

    Pentoxifylline is completely amenable to the exchange processes of , more than 90% is utilized through the kidneys, with urine. However, excretion of the active substance may be delayed in patients suffering from renal dysfunction.

    In patients susceptible to impaired liver function, the drug is delayed in the body for longer, since it will also take longer to digest.

    Solution for infusion

    Pentoxifylline is actively processed in the liver and erythrocytes. The most known cleavage products are metabolite-1 and metabolite-5, which are formed in the as a result of the oxidation process. These metabolites have the same pharmacological properties as pentoxifylline.

    More than 90% of the active substance is excreted with urine, and 3-4% - with calories.

    The substance comes to a half-life after 1.1 hours( a dose of 100 g.).In patients with severe hepatic insufficiency, the half-life of pentoxifylline increases.

    Pentoxifylline has a high rate of excretion from the body ( 4500-5100 ml per minute).

    If the patient suffers from impaired renal function, the split product is excreted longer.

    When to take medicine, and when there is no

    How the medication

    works The instruction for use indicates that the tablet Trenal increases the blood flow of the , due to the effect on the possibility of deformability of red blood cells. Also, it lowers the coagulability of platelets, thereby reducing superhuman blood.
