Article Abstract
The purpose of the study was to develop an SNEDDS to improve the solubility and bioavailability of pitavastatin. The solubility of pitavastatin in different oils, surfactants, and co-surfactants was determined and a pseudo-ternary phase diagram was constructed. The SNEDDS was characterized by zeta-sizer, zeta-potential, FTIR, DSC, and TGA. Release and permeation of pitavastatin from the SNEDDS was studied for 12 and 24 h, respectively. The lipolysis test, RBC lysis, effect on lipid profile, and pharmacokinetics were studied. The SPC3 formulation showed a 104 ± 1.50 nm particle size, a 0.198 polydispersity index (PDI), and a -29 zeta potential. FTIR, DSC, and TGA showed the chemical compatibility and thermal stability. The release and permeation of pitavastatin from SPC3 was 88.5 ± 2.5% and 96%, respectively. In the lipolysis test, the digestion of SPC3 yielded a high amount of pitavastatin and showed little RBC lysis. The lipid profile suggested that after 35 days of administration of the SNEDDS, there was a marked decrease in TC, LDL, and triglyceride levels. The SNEDDS of SPC3 showed an 86% viability of Caco-2 cells. Pharmacokinetics of SPC3 showed improved values of C, T, half-life, MRT, AUC, and AUMC compared to the reference formulation. Our study demonstrated that the SNEDDS effectively enhanced the solubility and bioavailability of a BCS class II drug.

Metal ions play a vital role in the health of the modern human body, but deficiencies in mineral elements have created health risks worldwide. However, mineral supplements currently available on the market are very limited due to poor solubility, low bioavailability, and the possibility of adverse effects on the gastrointestinal tract. In contrast, protein-derived metal-chelating peptides have received a lot of attention because of their stability, safety, and very high bioavailability.

Nimodipine (NMP), a poorly water-soluble small-molecule agent, demonstrates notable therapeutic limitations in addressing cerebral vasospasm secondary to subarachnoid hemorrhage (SAH). Owing to its inherent physicochemical properties characterized by low oral bioavailability, rapid elimination half-life, and extensive first-pass metabolism, conventional formulations necessitate frequent dosing regimens to sustain therapeutic plasma concentrations. These pharmacological challenges collectively result in suboptimal patient adherence, marked plasma concentration fluctuations, and recurrent vascular irritation.

Phytosterols are a class of natural steroids found in various plants. Commercially available phytosterols (PS) are primarily extracted from the deodorized distillate of soybean oil and consist predominantly of β-sitosterol with smaller amounts of stigmasterol and campesterol. Numerous studies have consistently demonstrated the significant lipid-lowering activity of PS.

Vitiligo, a chronic autoimmune disorder characterized by the presence of depigmented skin patches, remains a therapeutic challenge due to its multifactorial pathogenesis and the absence of highly effective treatment options. Although the exact etiology of vitiligo is not fully understood, factors such as genetic factors, oxidative stress, autoimmunity, and inflammation are implicated in the destruction of melanocytes. Current therapeutic strategies primarily focus on modulating immune responses and alleviating oxidative stress.
