Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine if pyridostigmine bromide improves heart rate variability of type 2 diabetes mellitus subjects with cardiovascular autonomic neuropathy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The reduced heart rate variability is associated with increased risk of death in patients with diabetes mellitus. Cholinesterase inhibition with pyridostigmine bromide increases heart rate variability in normal individuals and congestive heart failure subjects but its effects on patients with diabetes mellitus is unknown. Based on those evidences, we will test if the short-term administration of pyridostigmine bromide increases heart rate variability in patients with diabetes mellitus.
