Abstract :
Background:
Pioglitazone, a thiazolidinedione (TZD) and selective peroxisome proliferator-activated receptor-gamma (PPARγ)
agonist, exerts pleiotropic effects on lipid homeostasis that extend well beyond its primary glucose-lowering activity. In the
context of the global obesity epidemic and the rising prevalence of metabolic syndrome, understanding its lipid-modifying
properties is of paramount clinical importance.
Objective:
This comprehensive review synthesizes current evidence on pioglitazone-mediated modulation of lipid metabolism in
obese and metabolic syndrome patients, examining molecular mechanisms, clinical outcomes, hepatic effects, and safety
considerations.
Methods:
A systematic search of PubMed, MEDLINE, Cochrane Library, and ClinicalTrials.gov databases was conducted.
Studies published between 2000 and 2024 examining pioglitazone's lipid effects, mechanisms of action, and clinical outcomes
were included.
