Preparation, characterization, and in vitro cytogenotoxic evaluation of a novel dimenhydrinate-β-cyclodextrin inclusion complex.

Dimenhydrinate (DMH), used to alleviate motion sickness symptoms such as nausea, vomiting, dizziness, and vertigo, encounters limitations in oral pharmaceutical formulations due to its poor water solubility and bitter taste. Our research hypothesized that inclusion complexation with β-cyclodextrin (β-CD) might address these drawbacks while ensuring that the newly formed complexes exhibit no cytotoxic or genotoxic effects on peripheral blood mononuclear cells (PBMCs). Inclusion complexes were prepared using the kneading method and the solvent evaporation method.

Sweeteners in Orodispersible Films: How Much is too Much?

Four natural sweeteners (sucrose, xylitol, fructose, and isomalt) were selected to examine the influence of their qualities and amounts on the characteristics of orodispersible films. Sodium carboxymethylcellulose (2% w/w) was utilized as the film-forming polymer and 1% w/w glycerol as a plasticizer. Films were produced through the solvent casting method, rendering them suitable for convenient application in community or hospital pharmacy settings.

Development and Characterization of Cationic Nanostructured Lipid Carriers as Drug Delivery Systems for miRNA-27a.

Although miRNA-27a has been identified as a promising candidate for miRNA mimic therapy of obesity, its application is limited due to enzymatic degradation and low membrane permeation. To overcome these problems, we developed cationic nanostructured lipid carriers (cNLCs) using high-pressure homogenization and used them as non-viral carriers for the anti-adipogenic miRNA-27a. Cargo-free octadecylamine-containing NLCs and miRNA/cNLC complexes were characterized regarding particle size, size distributions, zeta potential, pH values, particle topography and morphology, and entrapment efficacy.

Quality by Design-Based Development of Solid Self-Emulsifying Drug Delivery System (SEDDS) as a Potential Carrier for Oral Delivery of Lysozyme.

For many years, researchers have been making efforts to find a manufacturing technique, as well as a drug delivery system, that will allow for oral delivery of biopharmaceuticals to their target site of action without impairing their biological activity. Due to the positive in vivo outcomes of this formulation strategy, self-emulsifying drug delivery systems (SEDDSs) have been intensively studied in the last few years as a way of overcoming the different challenges associated with the oral delivery of macromolecules. The purpose of the present study was to examine the possibility of developing solid SEDDSs as potential carriers for the oral delivery of lysozyme (LYS) using the Quality by Design (QbD) concept.

A Critical Assessment of Extemporaneous Formulations for Proton Pump Inhibitors: The Importance of Proper Vehicle Selection.

Objective: To examine the influence of vehicles on the stability of extemporaneous suspensions of proton pump inhibitors (PPIs), to single out the formulation most suitable for children, providing appropriate evidence and arguments.

Methods: A review was performed of data identified from Medline, Embase, Science Direct, as well as public digital archive PubMed, including reference texts, related to the field of stability testing of extemporaneous PPI suspensions.

Results: Fourteen selected formulations of extemporaneous suspensions are presented and discussed.
