Albendazolum (ABZ) is a BCS class II drug. It has challenging biopharmaceutical properties, which include poor solubility and dissolution rate. These properties have laid the ground for developing a supersaturated self-nanoemulsifying drug delivery system (S-SNEDDS) to form oil-in-water nanoemulsion to improve the oral bioavailability of ABZ. Based on the ABZ solubility, emulsifying ability, and stability after dispersion in an aqueous phase, an optimal self-nanoemulsifying drug delivery system (SNEDDS) consisting of oleic acid, Tween 20, and PEG 600 (X:Y:Z, w/w) was identified, having 10% (w/w) hydroxypropyl methylcellulose (HPMC) E15 lv as its precipitation inhibitor. The optimized system possessed a small mean globule size value (89.2 nm), good dispersion properties (polydispersity index (PDI): 0.278), and preserved the supersaturated state of ABZ. S-SNEDDS was transformed into solid supersaturated self-nanoemulsifying drug delivery systems (SS-SNEDDS) using microcrystalline cellulose as a solid material. The developed S-SNEDDS were characterized for globule size, pH, turbidity, differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and flow properties. The data obtained from the results suggest that this S-SNEDDS formulation can enhance the solubility and oral bioavailability of ABZ for appropriate clinical application.

Abiraterone acetate, a prodrug of abiraterone, is an effective antiandrogen for treating metastatic prostate cancer. However, its poor aqueous solubility restricts oral bioavailability to under 10% in fasted conditions. Additionally, its pharmacokinetics are significantly influenced by food intake, leading to variable exposure that can impact treatment safety and efficacy.

Dasatinib (DASA), a potent second-generation multitarget kinase inhibitor marketed as Sprycel® (Tablet), is limited by poor oral bioavailability (14-24 %) and dose-related gastrointestinal side effects. A supersaturable self-nanoemulsifying drug delivery system (su-SNEDDS) designed to enhance DASA's solubility, sustain supersaturation, and improve oral bioavailability. The su-SNEDDS formulation comprises DASA, an oil, surfactant, co-surfactant, and polyvinylpyrrolidone (PVP) K30 as a precipitation inhibitor (PI).

This study aimed to investigate the in vitro performance of self-nanoemulsifying drug delivery systems (SNEDDSs) of Ornidazole (ORD), a poorly water-soluble drug. Self-nanoemulsifying drug delivery systems of ORD were prepared using various oils, non-ionic surfactants, and/or water-soluble co-solvents and assessed visually/by droplet size measurement. Equilibrium solubility of ORD in the anhydrous and diluted SNEDDS was conducted to achieve the maximum drug loading.

Thermoresponsive self-nanoemulsifying drug delivery systems (T-SNEDDS) offer a promising solution to the limitations of conventional SNEDDS formulations. Liquid SNEDDS are expected to enhance drug solubility; however, they are susceptible to leakage during storage. Even though solid SNEDDS offers a solution to this storage instability, they introduce new challenges, namely increased total dosage and potential for drug trapping within the formulation.
