§5Regulatory status

§5.1Status by jurisdiction

Table 5. Regulatory status of Glutathione by jurisdiction, as recorded at the assessment date.

JurisdictionStatusDetail
Italy and some other jurisdictionsAuthorisedAvailable as an authorised medicinal product in a small number of countries, principally as an adjunct in cisplatin neurotoxicity
United StatesNot approved as a parenteralMarketed as a dietary supplement in oral form; parenteral preparations are compounded
Philippines and elsewhereRegulatory warnings issuedAdvisories against intravenous glutathione for skin lightening
Research-use supplyVariableWidely available; the material itself is a well-characterised pharmacopoeial-grade chemical, unlike most compounds in this series
Recorded at the assessment date. Regulatory status changes and this table is re-examined at each review.

§5.2Development status

Unapproved, research supply. Supplied as a research chemical; no marketing authorisation for the uses under which it is supplied.

§5.3Supply outside authorisation

Material offered by research-chemical suppliers is not manufactured under a marketing authorisation, is not subject to the quality system that governs an authorised product, and is not covered by any pharmacovigilance obligation. The distinction matters for this monograph because every efficacy and safety estimate reproduced in §3 and §4 was obtained using material manufactured under such a system. The Institute records supply considerations separately at §8 and analytical characterisation at §6.[1,2]

Nothing published by the Institute is medical advice, a diagnosis, a prescription, a treatment recommendation or a purchasing recommendation. Compounds supplied for research use are not approved for human or veterinary use in any jurisdiction, and a favourable analytical assessment of a supplier is not a statement that any product is safe or effective.
