Ferulic acid (FA) is a promising nutraceutical molecule which exhibits antioxidant and anti-inflammatory properties, but it suffers from poor solubility and bioavailability. In the presented study, FA nanoemulsions were prepared to potentiate the therapeutic efficacy of FA in prevention of gastric ulcer.


FA nanoemulsions were prepared, pharmaceutically characterized, and the selected nanoemusion was tested for its ulcer-ameliorative properties in rats after induction of gastric ulcer using ethanol, by examination of stomach tissues, assessment of serum IL-1β and TNF-α, assessment of nitric oxide, prostaglandin E2, glutathione, catalase and thiobarbituric acid reactive substance in stomach homogenates, as well as histological and immunohistochemical evaluation.


Results revealed that the selected FA nanoemulsion showed a particle size of 90.43 nm, sustained release of FA for 8 h, and better in vitro anti-inflammatory properties than FA. Moreover, FA nanoemulsion exhibited significantly better anti-inflammatory and antioxidant properties in vivo, and the gastric tissue treated with FA nanoemulsion was comparable to the normal control upon histological and immunohistochemical evaluation.


Findings suggest that the prepared ferulic acid nanoemulsion is an ideal anti-ulcer system, which is worthy of further investigations.
