Amtolmetin guacil

Amtolmetin guacil is a NSAID which is a prodrug of tolmetin sodium.

Tolmetin sodium is an effective NSAID approved and marketed for the treatment of rheumatoid arthritis, osteoarthritis and juvenile rheumatoid arthritis. In humans, tolmetin sodium is absorbed rapidly with peak plasma levels observed 30 min after p.o. administration, but it is also eliminated rapidly with a mean plasma elimination t½ of approximately 1 hr. The preparation of slow release formulations or chemical modification of NSAIDs to form prodrugs has been suggested as a method to reduce the gastrotoxicity of these agents.
