Means "Trilon B". Description

The "Trilon B" (disodium salt of ethylenediaminetetraacetic acid) is a crystalline white powder. The drug is soluble in water, almost insoluble in ether and alcohol.

The drug "Trilon B" in medicine

The agent can form various complexcompounds with a number of cations, including calcium ions. These properties allow the use of the drug in pathologies complicated excessive accumulation of calcium in the body (including the internal organs, muscle, venous walls), against the skeleton ossification, arthritis, scleroderma. The agent in some cases is prescribed to eliminate certain types of ectopic arrhythmias, especially those provoked by an overdose of cardiac glycosides. Due to its ability to bind calcium ions it is also used in the preservation of blood as an anticoagulant.

The drug Trilon B. Application

The main indication for the appointment of a medicationare pathologies with manifestations of calcification. They include, in particular, scleroderma, dermatomyositis, ossifying myositis. The administration of the drug is carried out intravenously. Before the infusion, the drug is diluted with sodium chloride (isotonic solution) or glucose solution (5%). The preparation "Trilon B" is administered at a rate of up to 12 drops / min. Patients with ten years are recommended to 10 milliliters of a 5 per cent solution, diluted 200 ml of the solvent. The medication is administered in cycles. Patients under 10 years of age are prescribed 5 ml of the drug, diluted in 100 ml of the solvent. The course of therapy includes fifteen injections. The medication is administered once a day for five days with weekly interruptions. Thus, the course includes three five-day cycles with seven-day intervals.

Contraindications and side effects

Not recommended drug Trilon B with reducedblood coagulability, hemophilia, liver pathology or kidney. Contraindications include hypocalcemia. During the introduction at a high rate, the development of tetany is likely. In this case, stop the infusion. Some patients with the introduction of "Trilon B" in the vein feel a burning sensation, which can spread throughout the body and persist for one or two hours after the injection.

special instructions

During therapy, it should be noted thatthe effectiveness of the drug without the appearance of negative consequences is possible with a low rate of introduction into the flow of blood. Under such conditions, the drug slowly interacts with the blood serum calcium. In this regard, the content of Ca does not decrease significantly, since its loss is compensated for by mobilization of the compound from the tissues (bone, in particular) and excessive accumulations in the organs. Against the background of rapid drug administration, physiological mechanisms are not able to quickly eliminate the decrease in serum calcium levels. As a result, acute tetany can develop.

How else is Trilon B used?

The remedy is used not only for medicinal purposes. The drug is used in analytical chemistry, for quantitative and qualitative assessment of metal salts. This is made possible by the ability of the substance to form complexion ions with different colors. Ammonia solution Trilon B is used to restore the batteries. This method is characterized by efficiency and high efficiency. Pre-charge the discharged battery, then drain the electrolyte from it and rinse with water two or three times. After it is necessary to pour ammonia solution, which includes two weight percent of the agent and five percent ammonia.

The duration of desulfation is of the order offorty to sixty minutes. The process is accompanied by gas emissions and the appearance of small sprays on the surface. With strong sulfation, the procedure can be repeated. At the end of the process, gas evolution ceases. After processing the battery using Trilon B, it is recommended to rinse the unit with distilled water at least three times. After it is filled with electrolyte of normal density and charged. The aqueous solution of Trilon B is also used for cleaning pipelines. The connection is poured into the system and pumped through it for one and a half to two hours. The processing temperature is 70-80 degrees. The spent solution is drained, and the system is washed with water about three times. As a result of these actions, the deposit of rust or scale is eliminated. In addition, the joint protects the rubber and plastic elements of the pipeline, since the agent does not interact with them and does not change their pH. Similarly, the drug is used to clean the car cooling system. As a separate agent or in a mixture with a detergent, the substance is used to protect washing machines from plaque formation.
