Objective: This study was conducted with four objectives in mind, including: (1) characteristics of self-medication; (2) storage of drugs at home; (3) factors associated with storage of drugs at home; and (4) comparison of the level and sources of knowledge between over-the-counter (OTC) and prescription-only (POM) medication consumers.
Methods: A cross-sectional survey was conducted in 2007 using a semi-structured questionnaire on 300 clients of 21 drugstores (from a total of 214 drugstores in the city of Tabriz, Iran).
Results: The highest demand for drugs was for analgesics (from OTC drugs) and antibiotics (from POM drugs). Of 325 requests for medications by 300 customers of drugstores in Tabriz, aged 15 years or higher, 50.8% (165 requests) were for OTC drugs and 49.2% (160 requests) were for POM drugs, twenty-five cases requested both OTC and POM medications. There were 246 customers (82%) who reported that they stored drugs at home. Physicians were reportedly the most common source of information about medications, while the highest-quality information was obtained from pharmacists.
Conclusion: The frequency of home storing of medications was very high in this study. Customers, especially the lower education groups, had very little information about the side effects of drugs and differentiation of OTC and POM medications. Wayward use of antibiotics was very high among the drugstore clients. It seems that the information provided by the pharmacists can be one of the most effective ways for advancing the level of knowledge among the consumers of medications.

Enhancing drug solubility through competitive adsorption on silica nanosurfaces with ultrahigh silanol densities.

We develop a technology based on competitive adsorption between drug molecules and water, specifically designed to address the critical issue of poor drug solubility. By specially engineering silica nanosurfaces with ultrahigh densities of silanol, we significantly enhance their affinity for both drug molecules and water, with a notably greater increase in water affinity. Such surfaces can effectively adsorb a variety of drug molecules under dry conditions.

Natural enzymes are a class of biological catalysts that can catalyze a specific substrate. Although natural enzymes have catalytic activity, they are susceptible to the influence of external environment such as temperature, and storage requirements are more stringent. Since the first discovery of magnetic FeO nanoparticles with peroxidase-like activity in 2007, the research on nanoenzymes has entered a rapid development stage.

Magnetoliposomes containing magnetite, soy lecithin, stigmasterol, and beta-sitosterol of the mean size minor than 160 nm were obtained by a scalable and green process using autoclave and sonication without organic solvents. The formation, size of the liposome, linkage, and encapsulation of the magnetite were evaluated by Cryo-TEM. The stability of magnetoliposomes after storage for 6 months at 4 °C was improved by liposome size, the ability of soy lecithin to preserve the magnetite phase against oxidation, pH, polydispersity index, and zeta potential.

The study involves the modification of a non-conventional starch isolated from the under-utilized variety of Chinese water chestnut (CWC (Eleocharis tuberosa) and integrating it to fabricate stabilized and curcumin-enriched Pickering emulsions with enhanced bioavailability, thermal stability, and retention of encapsulated curcumin. A time-efficient, semi-dried esterification method was used to prepare modified amphiphilic starches using 3, 6, or 9 % (w/v) octenyl succinic anhydride (OSA) and characterized through degree of substitution (DS), contact angle, particle size, scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and in-vitro digestibility. Moreover, Pickering emulsions were formulated using CWCS-OSA at 3 %, 6 %, or 9 % concentrations to serve as a carrier for curcumin to improve its water solubility and storage stability.

Amorphous solid dispersions (ASDs) are widely recognized for their potential to enhance the solubility of poorly water-soluble drugs, with factors such as molecular mobility, intermolecular interactions, and storage conditions playing critical roles in their performance. However, the influence of preparation methods on their performance remains underexplored, especially regarding their supersaturation performance. To address this gap, the present study systematically investigates ASDs of ibuprofen (IBU, used as a model drug) prepared using two widely utilized techniques (solvent evaporation, SE, and melt-quench cooling, M-QC).
