Cases, Evidence <strong>and</strong> Verdicts- The Glitazone Controversy<br />
What would be reasonable conclusions to draw from<br />
these varying results?<br />
1. Thiazolidinediones are approved monotherapy agents<br />
in treatment <strong>of</strong> type 2 diabetes mellitus. They are also<br />
indicated for use in combination with sulfonylurea,<br />
metformin, or insulin when diet <strong>and</strong> exercise plus the<br />
single agent does not result in adequate glycemic control.<br />
However they should be used cautiously, if at<br />
all, in those with cardiovascular disease.<br />
2. They may be used in those with IFG/IGT with high<br />
risk <strong>of</strong> diabetes.<br />
3. Pioglitazone would clearly seem to be preferable to<br />
rosiglitazone in view <strong>of</strong> its favorable lipid lowering<br />
pr<strong>of</strong>ile <strong>and</strong> less cardiovascular events <strong>and</strong> can be considered<br />
the agent <strong>of</strong> choice if a thiazolidinedione is<br />
required.<br />
4. The treating clinician should carefully consider the<br />
need for any thiazolidinedione before prescribing one<br />
<strong>and</strong> should refrain from using rosiglitazone in the absence<br />
<strong>of</strong> exceptionally compelling circumstances.<br />
