We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Moxonidine 0.2 MG
Other interventions - placebo

Experimental: No conditioning + placebo - Participants will be given placebo to take orally 20 minutes prior to the first endothelial function measurement without conditioning tests.

Experimental: No conditioning + moxonidine - Participants will be given moxonidine to take orally 20 minutes prior to the first endothelial function measurement without conditioning tests.

Experimental: Remote pre-conditioning + placebo - Participants will be given placebo to take orally 20 minutes prior to the first endothelial function measurement with conditioning tests.

Experimental: Remote pre-conditioning + moxonidine - Participants will be given moxonidine to take orally 20 minutes prior to the first endothelial function measurement with conditioning tests.


Treatment: Drugs: Moxonidine 0.2 MG
Subjects will be allocated to undergo conditioning or non conditioning assigned in a randomized order. Participants will be given placebo or 0.2mg of Moxonidine to take orally 20 minutes prior to the first endothelial function measurement.

Other interventions: placebo
Subjects will be allocated to undergo conditioning or non conditioning assigned in a randomized order. Participants will be given placebo or 0.2mg of Moxonidine to take orally 20 minutes prior to the first endothelial function measurement.

Summary
Brief summary
This study is designed to assess the effect of forearm ischemia-reperfusion injury on
sympathetic nerve activity. To determine whether reduced sympathetic responsiveness is a
contributor to the protective effects of remote ischemic preconditioning. In addition it will
assess whether pharmacologic inhibition of the sympathetic nervous system can ameliorate
ischemia reperfusion injury induced endothelial dysfunction.
