Advantages
TZDs increase HDL-C and lower triglycerides, lower blood pressure, reduce markers of inflammation, reduce hepatic steatosis, decrease carotid and coronary artery thickening and prevent restenosis aſter percutaneous transluminal coronary angioplasty.
Impair breakdown of starches in GI tract, reducing PPG excursions.

and various serotonin receptors. It also inhibits the release of glutamate by reversing the glutamate GLT-1 transporter.
