Bemiparin improves the total antioxidant status in plasma.

Area of Science:

• Biochemistry
• Pharmacology

Background:

• Oxidative stress is implicated in various physiological and pathological conditions.
• Anticoagulants may possess properties beyond their primary function.

Purpose of the Study:

• To evaluate the antioxidant effects of bemiparin in healthy individuals.
• To assess bemiparin's impact on key oxidative stress biomarkers in plasma.

Main Methods:

• Plasma samples from healthy volunteers (n=20 treated, n=15 control) were analyzed.
• Measurements included total antioxidant activity, superoxide dismutase, glutathione peroxidase, oxidized glutathione, and malondialdehyde.
• Blood was collected at basal, 2, 4, 6, 8, and 10 hours post-administration.

Main Results:

• The bemiparin-treated group exhibited higher total antioxidant activity and antioxidant enzyme activity at 2-6 hours.
• Conversely, oxidized glutathione and malondialdehyde levels were significantly lower in the treated group during the same period.
• These findings indicate a rapid onset of antioxidant action.

Conclusions:

• Bemiparin demonstrates a significant early protective effect against oxidative stress in human plasma.
• The study suggests potential pleiotropic benefits of bemiparin beyond anticoagulation.
