Formulation, characterization, pharmacokinetics and antioxidant activity of phloretin oral granules.

Phloretin (PHL), a flavonoid of the dihydrogen chalcone class, is reported to have low oral bioavailability due to its poor solubility and absorption. A common approach to enhance the solubility of such flavonoids is solubilization in a polymeric or lipidic matrix which would help in enhance dissolution rate and solubility. Accordingly, in the current study PHL was dissolved in Gelucire® 44/14 by melt-fusion technique and the viscous semisolid melt was adsorbed on a solid carrier to obtain free flowing granules.

A concise summary of powder processing methodologies for flow enhancement.

The knowledge of powder properties has been highlighted since the 19th century since most formulations focus on solid dosage forms, and powder flow is essential for various manufacturing operations. A poor powder flow may generate problems in the manufacturing processes and cause the plant's malfunction. Hence these problems should be studied and rectified beforehand by various powder flow techniques to improve and enhance powder flowability.

Insights on the Critical Parameters Affecting the Probiotic Viability During Stabilization Process and Formulation Development.

Probiotics have gained a lot of interest in recent years as an alternative as well as adjuvant therapy for several conditions owing to their health benefits. These live microorganisms have proven efficacy for treating gut disorders, inflammation, bacterial vaginosis, hepatic and depressive disorders, and many more. There are conventional as well as non-conventional formulations available for the delivery of probiotics with the latter having fewer regulatory guidelines.

Thermodynamic aspects of the preparation of amorphous solid dispersions of Naringenin with enhanced dissolution rate.

Amorphous ternary solid dispersions of poorly water-soluble Naringenin (NRG) in Poloxamer 188 (POX) and Neusilin US2 (NSL) were prepared in a Hot- Melt Extruder (HME) using the principle of Low-Temperature Solubilization (LTS). Before HME, the NRG-POX solid-state interaction was investigated using Flory Huggins (F-H) theory. Construction of the composition-phase diagram showed Gibbs free energy to be negative close to the melting temperature of NRG, indicating a miscible system.
