Pharmacological properties
Pharmacodynamics
Glutathione is a tripeptide that is a natural component of cells of all tissues of the body. Its significant distribution is associated with a wide range of biological functions and has fundamental importance for numerous biochemical and metabolic processes.
The sulfhydryl groups of cysteine that are part of glutathione are powerful nucleophilic agents. In connection with this, they become the main target of electrophilic attack by chemicals or their active metabolites, which leads to the inactivation of potentially toxic exogenous substances. Thus, the drug has a protective effect on vital nucleophilic areas, the attack on which begins the process of cell damage.
In addition, glutathione (GSH), restored as a result of interaction with a large number of oxidized organic metabolites, forms less toxic conjugated compounds, which are further easily metabolized and excreted in the form of mercapturic acids.
Given these properties, glutathione is prescribed in cases of hepatotoxicity reactions, the mechanisms of development of which may be ethyl or medicinal hepatotoxicosis or pathogenetically caused hepatotoxicosis associated with violations of detoxification mechanisms.
Pharmacokinetics
After intravenous administration, glutathione is mainly distributed in erythrocytes, while in plasma it is quickly broken down by gamma-glutamyltranspeptidase and gamma-glutamyl-cyclotransferase. Thus, the plasma level of reduced glutathione (GSH), even after the use of high doses, is insignificant (peak concentration in plasma is approximately 1 nmol/ml 5 minutes after intravenous administration of 600 mg), while the level of cysteine metabolite is higher (peak concentration in plasma is approximately 17 nmol/ml). The concentration in the blood, determined in whole blood, reaches a value of approximately 100 nmol/ml 5-10 minutes after intravenous administration of 600 mg of glutathione. The concentration of the drug in the blood gradually decreases, almost reaching initial values approximately 60 minutes after administration.

Special warnings and precautions for use
Use during pregnancy or breastfeeding.
Although glutathione did not show any signs of embryotoxicity and fetotoxicity during experimental studies, its use is not recommended for pregnant women and women who are breastfeeding.
Ability to affect the reaction rate when driving vehicles or using other mechanisms.
Glutathione does not affect the ability to drive vehicles or use other mechanisms.
Dosage and administration
In the most severe degree of damage: 600-1200 mg (1-2 vials) per day by intramuscular or slow intravenous administration.
In moderate degree of damage: half of the above dose is used.
Preparation of the drug for administration
In the case of intramuscular administration, the drug must be completely dissolved directly in the vial using the solvent included in the package.
In the case of intravenous administration, the drug must be dissolved in the solvent from the package (water for injection) and administered either by direct slow injection or by infusion after adding the prepared solution to at least 20 ml of sterile infusion solution.
