(verify) Troglitazone (Rezulin, Resulin or Romozin) is an anti-diabetic and antiinflammatory drug, and a member of the drug class of the thiazolidinediones. It was developed by Daiichi Sankyo Co.(Japan). In the United States, it was introduced and manufactured by Parke-Davis in the late 1990s, but turned out to be associated with an idiosyncratic reaction leading to drug-induced hepatitis. One FDA medical officer evaluating troglitazone, John Gueriguian, did not recommend its approval due to potential high liver toxicity,[1] but a full panel of experts approved it in January 1997.[2] Once the prevalence of adverse liver effects became known, troglitazone was withdrawn from the British market in December 1997, from the United States market in 2000, and from the Japan market soon afterwards.
Mode of action
Troglitazone, like the other thiazolidinediones (pioglitazone and rosiglitazone), works by activating peroxisome proliferator-activated receptors (PPARs).
Troglitazone is a ligand to both PPARα and – more strongly – PPARγ. Troglitazone also contains an α-tocopheroyl moiety, potentially giving it vitamin E-like activity in addition to its PPAR activation. It has been shown to reduce inflammation:[3] troglitazone use was associated with a decrease of nuclear factor kappa-B (NF-κB) and a concomitant increase in its inhibitor (IκB). NFκB is an important cellular transcription regulator for the immune response.
