Safety Study of Pyridostigmine in Heart Failure

Completed · Phase 2 · Has a placebo group

Conditions studied: Heart Failure

In brief

Heart failure, a common heart disease affecting nearly 6 million Americans, is associated with high rates of hospitalization and death. Abnormalities in the autonomic nervous system are thought to play an important role in the progression of heart failure. This proposal aims to determine whether novel application of pyridostigmine, a drug currently approved by the FDA only for the treatment of neuromuscular disease, can improve autonomic nervous system function in heart failure patients.
