Pharmaceutical polymers and P-glycoprotein: Current Trends and Possible Outcomes in Drug Delivery
Drug resistance is considered a key reason behind the failure of therapeutic medications for several chronic diseases, including hypertension, cancer therapeutics, and antimicrobial agents. Among the strategies used to overcome drug resistance are therapeutic targeting of other factors involved in…

Loading of alpha-tocopherol in a nonionic microemulsion: phase behaviour and structural…
In this research, we present a systematic analysis of events inside single phase region of a nonionic microemulsion (ME) during incorporation of water and α-tocopherol (AT, a hydrophobic payload). The formulation was developed using α-tocopherol polyethylene glycol succinate, ethanol and oleic acid,…

Inhaled dry powder cisplatin increases antitumour response to anti-PD1 in a murine lung cancer model
Despite advances in targeted therapies and immunotherapy in lung cancer, chemotherapy remains the backbone of treatment in most patients at different stages of the disease. Inhaled chemotherapy is a promising strategy to target lung tumours and to limit the induced severe systemic toxicities.…

Biocompatible phospholipid-based mixed micelles for posaconazole ocular delivery: Development,…
Current study intended to prepare and evaluate phospholipid-based, mixed micelles (MMs) to improve the ocular delivery of posaconazole (POS), a broad-spectrum antifungal drug. For this, MMs based on egg phosphatidylcholine (EPC), as the main component, in combination with various bile salts (sodium…

The effects of surfactants on the performance of polymer-based microwave-induced in situ…
Microwave-induced in situ amorphization is a novel technology for preparing amorphous solid dispersions (ASDs) to address the challenges of their long-term physical stability and downstream processing. To date, only few types of dielectric materials have been reported for microwave-induced in situ …

Enhancing oral bioavailability of andrographolide via sodium dodecyl sulfate and D-α-Tocopherol…
Nanocrystal technology is a common strategy to enhance the oral bioavailability of poorly-soluble drugs, and how to enlarge the enhancing ability on oral absorption via nanocrystals has become a pharmaceutical research field. In this study, we selected andrographolide (ADR), a typical poorly-soluble…

TPGS Decorated Liposomes as Multifunctional Nano-Delivery Systems
Liposomes are sphere-shaped vesicles that can capture therapeutics either in the outer phospholipid bilayer or inner aqueous core. Liposomes, especially when surface-modified with functional materials, have been used to achieve many benefits in drug delivery, including improving drug solubility,…

In Vitro and In Vivo Effect of pH-Sensitive PLGA-TPGS-Based Hybrid Nanoparticles Loaded with…
Doxorubicin (DOX) is an antineoplastic agent clinically employed for treating breast cancer patients. Despite its effectiveness, its inherent adverse toxic side effects often limit its clinical application. To overcome these drawbacks, lipid–polymer hybrid nanoparticles (LPNP) arise as promising…

Emulsification by vitamin E TPGS or Quillaja extract enhanced absorption of berberine without…
Berberine is widely used for the prevention of cancers and diabetes. However, the absorption rate of berberine is less than 1% in humans. The objective of this research was to determine whether emulsification improves the absorption and affects the metabolism of orally ingested berberine. Twelve…
