The Application of Nano Drug Delivery Systems in Female Upper Genital Tract Disorders.

The prevalence of female reproductive system disorders is increasing, especially among women of reproductive age, significantly impacting their quality of life and overall health. Managing these diseases effectively is challenging due to the complex nature of the female reproductive system, characterized by dynamic physiological environments and intricate anatomical structures. Innovative drug delivery approaches are necessary to facilitate the precise regulation and manipulation of biological tissues.

Co-Processed Crystalline Solids of Ivermectin with Span 60 as Solubility Enhancers of Ivermectin in Natural Oils.

Despite being discovered over five decades ago, little is still known about ivermectin. Ivermectin has several physico-chemical properties that can result in it having poor bioavailability. In this study, polymorphic and co-crystal screening was used to see if such solid-state modifications can improve the oil solubility of ivermectin.

Combining Chemical Permeation Enhancers for Synergistic Effects.

Currently, macromolecular drugs such as proteins are mainly administered by means of injections due to their low intestinal epithelial permeability and poor stability in the gastrointestinal tract. This study investigated binary combinations of chemical drug absorption enhancers to determine if synergistic drug absorption enhancement effects exist. Aloe vera, Aloe ferox and Aloe marlothii leaf gel materials, as well as with N-trimethyl chitosan chloride (TMC), were combined in different ratios and their effects on the transepithelial electrical resistance (TEER), as well as the transport of FITC-dextran across Caco-2 cell monolayers, were measured.

Paracellular drug absorption enhancement through tight junction modulation.

Introduction: Inclusion of absorption-enhancing agents in dosage forms is one approach to improve the bioavailability of active pharmaceutical ingredients with low membrane permeability. Tight junctions are dynamic protein structures that form a regulated barrier for movement of molecules through the intercellular spaces across the intestinal epithelium. Some drug absorption enhancers are capable of loosening tight junctions and thereby facilitate paracellular absorption of drug molecules.

S-nitrosylation and attenuation of excessive calcium flux by pentacycloundecane derivatives.

A novel series of polycyclic amines, containing nitrogen monoxide donating moieties, were synthesised and tested for calcium channel and N-methyl-D-aspartate receptor modulating activity. The synthesised compounds were classified into two groups, based on their nitrogen monoxide donating moieties: unsaturated nitro compounds (1, 2 and 3) and nitro esters, or nitrates (4, 5 and 6). The nitrates were obtained via the reaction of hydroxyl functionalities with thionylchloride nitrate.
