Tolmetin is a non-steroidal anti-inflammatory drug (NSAID) previously used for the treatment of pain and inflammation associated with conditions like rheumatoid arthritis and osteoarthritis. Its use has declined and is currently discontinued or unavailable in many markets due to safety concerns and availability of alternative NSAIDs.
Pharmacokinetics
Pharmacokinetic parameters estimated for healthy adult subjects after oral administration, as no direct publications for tolmetin with ATC code M02AA21 (topical) were identified. Values are extrapolated from available data on oral tolmetin, as topical/systemic PK data for M02AA21 are absent in the literature.
