Abstract

Background: The metabolic syndrome (MetS) is an obesity-driven disorder with pandemic proportions and limited treatment options. Oxidative stress, low-grade inflammation and altered autonomic regulation, are important components of MetS pathophysiology. We recently reported that galantamine, an acetylcholinesterase inhibitor and an FDA-approved drug (for Alzheimer's disease) alleviates the inflammatory state in MetS subjects. Here we examined the effects of galantamine on oxidative stress in parallel with inflammatory and cardio-metabolic parameters in subjects with MetS. Methods: The effects of galantamine treatment, 8 mg daily for 4 weeks, followed by 16 mg daily for 8 weeks or placebo were studied in randomly assigned subjects with MetS (n=22 per group) of both genders. Oxidative stress, including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase activities, lipid and protein peroxidation, and nitrite levels were analyzed before and at the end of the treatment. In addition, plasma cytokine and adipokine levels, insulin resistance (HOMA-IR) and other relevant cardio-metabolic indices were analyzed. Autonomic regulation was also examined by heart rate variability (HRV) before treatment, and at every 4 week...Continue Reading

Anti-inflammatory Treatments

A drug or substance that reduces inflammation (redness, swelling, and pain) in the body. Anti-inflammatory agents block certain substances in the body that cause inflammation and swelling. Discover the latest research on anti-inflammatory treatments here
