Nose to brain delivery of tailored clozapine nanosuspension stabilized using (+)-alpha-tocopherol…
Clozapine is widely used to treat schizophrenia as an atypical antipsychotic. Low solubility, poor dissolution rate, degradation in the gastrointestinal tract, high hepatic first-pass metabolism, and eventually less drug transfer in the brain are all issues with oral clozapine administration. On…

Rp-HPLC Determination of Quercetin in a Novel D-α-Tocopherol Polyethylene Glycol 1000 Succinate…
Despite its proven efficacy in diverse metabolic disorders, quercetin (QU) for clinical use is still limited because of its low bioavailability. D-α-Tocopherol polyethylene glycol 1000 succinate (TPGS) is approved as a safe pharmaceutical adjuvant with marked antioxidant and anti-inflammatory…

Enhancing in vitro cytotoxicity of doxorubicin against MCF-7 breast cancer cells in the presence of…
This study was aimed to evaluate the impact of water-soluble β-cyclodextrin polymer (β-CDP), as a nanocarrier, on the therapeutic efficacy of the commercial doxorubicin (DOX). The β-CDP was synthesized by cross-linking of β-CD using epichlorohydrin. The chemical structure of the cross-linked β-CDP…

Generation of Ophthalmic Nanosuspension of Prednisolone Acetate Using a Novel Technology
Purpose
Prednisolone Acetate (PAC) is currently marketed as micronized ophthalmic suspension. The microsuspension has poor dose accuracy and efficacy due to aggregation, slow dissolution rate and limited corneal residence. The ophthalmic nanosuspension of PAC shall show enhanced solubility,…

Stability properties and antioxidant activity of curcumin nanosuspensions in emulsion systems
In this study, curcumin nanosuspensions (Cur-NSs) were prepared using D-alpha-tocopheryl polyethylene glycol succinate (vitamin E TPGS), and their physical properties (i.e., particle size, dispersion stability) were investigated. Also, the antioxidant activity of Cur-NSs in emulsion systems was…

Advancement on Sustained Antiviral Ocular Drug Delivery for Herpes Simplex Virus Keratitis: Recent…
The eyes are the window to the world and the key to communication, but they are vulnerable to multitudes of ailments. More serious than is thought, corneal infection by herpes simplex viruses (HSVs) is a prevalent yet silent cause of blindness in both the paediatric and adult population, especially…

Poloxamine/D-α-Tocopheryl polyethylene glycol succinate (TPGS) mixed micelles and gels: Morphology,…
The combination of polymeric surfactants with different features into mixed micelles give access to properties that may be superior to the single-component micelles. In this work, we investigated synergistic effects in mixtures of D-α-Tocopheryl polyethylene glycol succinate (TPGS) with poloxamines…

Nanocarriers based on vitamin E-TPGS: Design principle and molecular insights into improving the…
α-Tocopheryl polyethylene glycol succinate (Vitamin E-TPGS or TPGS) is a nonionic amphiphile synthesized by the esterification of vitamin E succinate. It has been categorized as a safe excipient by US-FDA and EMA. Like other polyethylene glycol (PEG) condensates, TPGS spontaneously forms kinetically…
