Mechanism of therapeutic action

As a medicinal product of magnesium sulfate,which is based on the clinical effects of its components, is widely used not only in therapy, but also in neurology, gynecology, dermatology. Magnesium is a competitive calcium antagonist, so it has a direct effect on metabolic processes in the cells of the body, the mechanism of transmission of the neuromuscular pulse in the cells of the nervous system and the excitability of the muscles. And the same effect on the mechanism of action and comparable in strength occurs in smooth and in striated muscle fibers. Simultaneously, this substance causes a marked slowing of the rhythm of heartbeats and a decrease in peripheral vascular resistance - that is why magnesium sulfate is prescribed for relief of hypertensive crises.

The sulphate group in this medicinalThe tool explains why magnesium sulfate, the use of which as a cholagogue and laxative means is in demand today, is considered the most effective drug for the treatment of constipation. When a solution of magnesia enters the intestine, the substance is practically not absorbed and causes a water retention in the lumen of the large intestine - after 2-4 hours the expected laxative effect occurs. In addition, the laxative effect of magnesia allows you to prescribe a drug to reduce absorption of any toxins from the intestine and accelerate the excretion of poisons during poisoning.

In surgical practice the drug is used inas a powerful tool for the treatment of wounds with abundant discharge (both serous and purulent) - the wound surface is drained and the possibility of suppuration develops.

In the first case, the drug inhibits the absorption of any chemical substance and fluid from the lumen of the large intestine. In the second case - relieves spasm of the musculature of the biliary tract, and already due to the influence of bile on the motility of the digestive tract, the passage of the contents of the intestine is accelerated.

Assigning magnesium sulfate intramuscularly, the doctortakes into account the spasmolytic and antihypertensive effect of the drug. That is why the drug is prescribed at the initial stage of hypertension, neurocirculatory dystonia due to hypertensive type or the initial stages of atherosclerosis and coronary heart disease.
