Background: Postoperative adhesions are a common complication following abdominal surgery, affecting over 90% of patients and leading to significant morbidity. Current anti-adhesion strategies, such as the use physical chemical barriers, have limitations short retention time, mechanical fragility, inefficient drug delivery. This study developed pectin-based emulsion gel loaded with celecoxib prevent provide localized pain relief. Methods: Formulations (F1–F4) different pectin concentrations...
This study aimed to improve the solubility and dissolution of aprepitant, a drug with poor aqueous solubility, using phosphatidylcholine (PC)-based solid dispersion system. When fabricating PC-based dispersion, we employed mesoporous microparticles, as an adsorbent, disintegrants sticky nature PC respectively. The dispersions were prepared by solvent evaporation technique characterized Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry, X-ray powder...
Purpurin-18 (P18) is one of the essential photosensitizers used in photodynamic therapy (PDT), but its hydrophobicity causes easy coalescence and poor bioavailability. This study aimed to synthesize P18 design P18-loaded solid lipid nanoparticles (SLNs) improve The characteristics synthesized SLNs were evaluated by particle release studies. effects using 1,3-diphenylisobenzofuran (DPBF) assay as a nonbiological phototoxicity against HeLa A549 cell lines biological assay. mean size zeta...
Photodynamic therapy (PDT) is a non-invasive and tumour-specific therapy. Photosensitizers (PSs) (essential ingredients in PDT) aggregate easily owing to their lipophilic properties. The aim of this study was synthesise PS (methyl pheophorbide a, MPa) design biocompatible lipid-based nanocarrier improve its bioavailability pharmacological effects. MPa-loaded nano-transfersomes were fabricated by sonication. characteristics synthesised assessed. effects PDT evaluated 1,3-diphenylisobenzofuran...
Adenosine (AD), which is used for treating wrinkles, exhibits poor skin permeation. The aim of the present study was to develop a cross-linked silicone-based cellulose elastomer as an elastic artificial treatment biocompatible lipid-based nano-carrier enhancing permeation AD, and formulation consisting carrier incorporated in skin. AD-loaded solid lipid nanoparticles (SLNs) were prepared using double-emulsion method. Particle characteristics mechanical properties SLNs skin, respectively,...
Itraconazole (ITZ) is an anti-fungal agent generally used to treat cutaneous mycoses. For efficient delivery of ITZ the skin tissues, oil-in-water (O/W) cream formulation was developed. The O/W base designed based on solubility measurement in various excipients. A physical mixture and also prepared as a control evaluate effects solubilized state vitro deposition behavior ITZ. Polarized light microscopy differential scanning calorimetry demonstrated that fully formulation. exhibited...
Cancer is a devastating disease and major human health concern. Various combination treatments have been developed to combat cancer. To obtain superior cancer therapy, the objective of this study was synthesize purpurin-18 sodium salt (P18Na) design P18Na- doxorubicin hydrochloride (DOX)-loaded nano-transferosomes as photodynamic therapy (PDT) chemotherapy for The characteristics DOX-loaded were assessed, pharmacological efficacy P18Na DOX determined using HeLa A549 cell lines. nanodrug...
Cancer is one of the most significant threats to human health. Following surgical excision, chemotherapy an effective strategy against remaining cancer cells. 4-hexylresorcinol (4-HR) has anti-cancer properties and exhibits hydrophobicity-induced aggregation in blood that trouble with targeted tumor delivery cellular uptake drug. The purpose this study encapsulate 4-HR into solid lipid nanoparticles (SLNs) enhance its effect by avoiding facilitating uptake.
The study aimed to assess the skin hydrating effect of hydrogels containing serine‐loaded solid lipid nanoparticles (SLN) prepared with lipids having high affinity stratum corneum (SC) and polysaccharide‐rich reed ( Phragmites communis ) root extract (RRE).
