Formation of PEG-PLGA Microspheres for Controlled Release of Simvastatin and Carvacrol: Enhanced Lipid-Lowering Efficacy and Improved Patient Compliance in Hyperlipidemia Therapy.

Polymer-based drug-controlled release systems offer greater efficacy and potency than conventional therapies. However, prominent drug side effects, lower circulation, and low drug loading capabilities limit their application range. In this work, the combination of Simvastatin (SIV) and Carvacrol (CAV) into PEG-PLGA microspheres (SIV-CAV-PP-MS) was achieved via an emulsification-solvent evaporation technique, resulting in microspheres characterized by high encapsulation efficiency and reduced particle size.

Design of Decanoic Acid/Polysorbate 80 Composite Vesicles as Cosmetics Carrier: Stability, Skin Permeability, Antioxidant and Antibacterial Activity.

Fatty acid vesicles are natural biomaterials which possess unique bilayer structures and offer biomimetic advantages for drug and gene delivery. Nevertheless, the formation of fatty acid vesicles is limited to neutral alkaline circumstances and cannot adapt to the acidic environment of the living system. In this work, the non-ionic surfactant polysorbate 80 (TW80) was introduced, extending the pH window of vesicles formed by decanoic acid (DA) from 6.

Design and Evaluation of Tretinoin Fatty Acid Vesicles for the Topical Treatment of Psoriasis.

The goal of the current study was to explore the potential benefits of Tretinoin (Tre) fatty acid vesicles (Tre-FAV) as a prospective antipsoriatic topical delivery system. This promising system can counteract the drug challenges in terms of its extremely low aqueous solubility, instability, skin irritation, and serious systemic adverse effects. Tre-loaded fatty acid vesicles were successfully developed and entirely characterised.
