Glutathione

Technical Monograph

Glutathione (GSH) is a tripeptide comprised of cysteine, glycine, and glutamic acid. It functions as the master antioxidant within eukaryotic cells, mitigating reactive oxygen species and facilitating phase II hepatic detoxification.

Mechanism of Action

GSH reduces reactive oxygen species (ROS) to water through glutathione peroxidase enzymes. It also conjugates directly with xenobiotics for cellular export via the multidrug resistance-associated protein (MRP) pumps.

Pharmacological Detail

The sulfhydryl group of cysteine serves as the potent electron donor in redox reactions. The ratio of reduced (GSH) to oxidized (GSSG) glutathione dictates cellular oxidative status.

Pharmacodynamics

Parenteral applications rapidly replenish depleted intracellular reserves, particularly in hepatic, pulmonary, and neurological tissues.

Pharmacokinetics

Due to poor oral bioavailability and rapid enzymatic degradation in the gut, systemic parenteral delivery ensures functional plasma and tissue distribution.

Preclinical Observations & In Vitro Data

Well-documented across a broad spectrum of medical literature involving antioxidant defense, immunology, and dermatology. Data cited from published literature.

Oxidative Stress Assays (Clinical): Significant reduction in circulating oxidative biomarkers established.
