Glutathione is used topically to treat corneal ulcers and keratitis, tablets are taken orally as an adjunct to chronic liver disease, and injections are used as an adjunct to alcohol/drug intoxication. Glutathione is a strong antioxidant that improves (liver) cell membrane stability, increases hepatic enzyme activity, and aids in liver detoxification and active repair by scavenging free radicals. Glutathione is categorized into ophthalmic preparations, tablets, and injections. Ophthalmic preparations can treat corneal ulcers/epithelial peeling, keratitis, and early stage senile cataracts when administered topically. Tablets for oral administration can be used as an adjunctive treatment for liver damage caused by viral, drug toxicity, and alcohol toxicity. Injections are used as adjunctive therapy for toxicity and liver damage caused by alcohol and certain drugs (e.g., chemotherapeutic drugs, antituberculosis drugs, antidepressants, etc.), as well as for the treatment of damage caused by ionizing rays, and for the adjunctive treatment of hypoxemia. It is contraindicated in pregnancy, breastfeeding, children under 18 years of age and those who are intolerant to the drug. Adverse reactions include allergy, hypotension, heart rate changes, dyspepsia, which improves with discontinuation of the drug. Specific use needs to be under the supervision of a clinician to avoid adverse events.
