NCT02406950

Brief Summary

Over the years, numbers of cardioprotective drugs have been evaluated to attenuate lethal ischemia-reperfusion (IR) injuries. There is little study whether sitagliptin protects against endothelial dysfunction induced by IR injury in humans.

Outcome Measures

Primary Outcomes (1)

  • The difference of FMD [brachial artery endothelium-dependent flow-mediated dilatation] after IR injury (brachial FMD before and after IR injury will be assessed)

    2 hours after study drug treatment

Secondary Outcomes (1)

  • The difference of FMD after IR injury in co-treatment of glibenclimide and sitagliptin ((brachial FMD before and after IR injury will be assessed)

    3.5 hours after study drug treatment

Other Outcomes (1)

  • Adverse events

    3 weeks

Study Arms (3)

Sitagliptin

EXPERIMENTAL

All participant will exam brachial artery endothelium-dependent flow-mediated dilatation (FMD). After then, pneumatic cuff wiil be inflated to 200 mmHg for 15 minutes to induce brachial artery ischemia. At the end of ischemia, 15 minutes of reperfusion was performed to induce reperfusion injury. After ischemia-reperfusion (IR) injury, brachial artery FMD will be measured again. After randomization, sitagliptin group will be treated by single dose of sitagliptin (Januvia) 50mg. In 2 hours later, brachial artery FMD measurement, IR injury and brachial artery FMD measurement will be measured again.

Drug: Sitagliptin

Placebo

PLACEBO COMPARATOR

After brachial artery FMD measurement, IR injury for each 15 minutes will be performed, and brachial artery FMD will be measured again. After randomization, placebo group will be treated by nothing. In 2 hours later, brachial artery FMD measurement, IR injury and brachial artery FMD measurement will be measured again.

Sitagliptin and glibenclimide

OTHER

If sitagliptin treatment show preventive effects of IR injury, the investigator will perform additional experiment to explore the mechanism (Protocol 2 study). Additional 15 healthy volunteers will be treated 5 mg of glibenclamide (Euglucon) 1 hour before administration of 50 m g of sitagliptin. In 2 hours after sitagliptin administration, FMD measurement before and after IR injury will be performed as described above.

Drug: Sitagliptin

Interventions

The brachial FMD before and after IR injury will be assessed. After randomization, study medication will be treated. In 2 hours later, the brachial FMD before and after IR injury will be assessed again. All volunteers had a wash-out period of 7 days. Seven days later, the subjects returned to crossover study medication (ie, sitagliptin or placebo), and the protocol described above was repeated.
