ATSTS Long tablets effervescent 600 mg

ATSTS Long is a mucolytics group medicine for the treatment of diseases of the respiratory tract, accompanied by difficulty in separating the sputum. For patients with chronic bronchitis and cystic fibrosis, the drug is recommended for prophylaxis to reduce the frequency and severity of the exacerbation stages.

Form of issue and composition

ATSTS Long is available in the form of water-soluble tablets, 6, 10 and 20 tablets per tube. The tube is placed in a cardboard box with instructions.

The main active ingredient is acetylcysteine. In 1 tablet of the drug contains 600 mg of acetylcysteine.

Auxiliary components: bicarbonate and sodium carbonate, ascorbic acid, lactose, sodium citrate dihydrate, mannitol, sodium saccharinate dihydrate, citric acid, sodium cyclamate, flavor with the smell of blackberries.

The tablets are white, with a flat surface and a dividing line. When the tablet is dissolved in 100 ml of water, a clear, colorless solution with a black smell is formed.

pharmachologic effect

Pharmacodynamics. Acetylcysteine ​​is a derivative of the amino acid cysteine. The mucolytic action of acetylcysteine ​​is due to its chemical structure: a free sulfhydryl group is present in the molecule of the compound that ruptures the disulfide bonds of acid mucopolysaccharides of sputum. As a result, bronchial mucus becomes less viscous, which facilitates its evacuation from the lumen of the bronchi and expectoration. Acetylcysteine ​​acts on phlegm both mucous and purulent.

The sulfhydryl groups of acetylcysteine ​​molecules are able to bind chemical radicals, thereby neutralizing their negative effect on the body and providing an antioxidant effect. In addition, acetylcysteine ​​enhances the synthesis of glutathione - one of the main protective factors of the body, has an antitoxic effect. During diseases of the respiratory tract, there is oxidative stress and general intoxication of the body. Providing antioxidant and antitoxic action, acetylcysteine ​​prevents the transition of pathology into a chronic form and accelerates the recovery of the patient.

Pharmacokinetics. The drug is rapidly absorbed, cleaved in the liver to the pharmacologically active metabolite of cysteine ​​and inactive compounds - diacetylcysteine, cystine, and subsequently - mixed disulfides. Bioavailability is about 10%. After 1-3 hours after the application of the drug, the concentration of the active substance in the blood plasma reaches a maximum. Blood proteins bind 50% of acetylcysteine. After cleavage and therapeutic action, the inactive metabolites of acetylcysteine ​​are excreted by the kidneys. The half-life is about 60 minutes. With functional violations of the liver this time increases to 8 hours.
