  • Hydrotrope dynamics: unraveling solubility pattern and correlation of benzimidazole using response surface methodology expert system

    Journal of Dispersion Science and Technology, 2025
    Solubilizing drugs in liquid and semisolid environments typically involves the use of cosolvents or surfactants. In contrast, the utilization of hydrotropic agents, which are small hydrophilic organic compounds like sodium salicylate or sodium benzoate, has been less explored in the field of pharmaceutical formulations. However, particularly in the context of topical dosage forms, hydrotropic solubilization can present valuable alternatives for enhancing solubility. One challenge in employing hydrotropic solubilization has been the unpredictability of its effectiveness with different drug molecules. In the current study, three different hydrotropes namely sodium salicylate, sodium benzoate, and pyrogallol were chosen to test the solubility enhancement of benzimidazole drug. Optimization of solubility was proceeded with Central Composite Design obtained from RSM expert system. It was noticed from the results that sodium salicylate had performed the best compared to the other two chosen hydrotropes. This was also reexamined using two models namely modified Apelblat model and polynomial model. The thermodynamic studies were assessed and it had reconfirmed the acquired solubility study results. The minimum and maximum hydrotrope concentrations of sodium salicylate required were 0.4 and 2.25 mol/L, respectively. The solubility enhancement factor was also remarkably high for sodium salicylate with 36.91 ± 0.07. With careful selection of the appropriate hydrotropic agent, the solubility of poorly soluble drug, benzimidazole has been significantly improved.

    Resveratrol, a stilbenoid polyphenol compound found in the skin and seeds of black grapes, which is supposed to have biological activity as an anti-inflammatory, anti-tumor, and anti-aging agent. Low oral bioavailability of resveratrol is determined by its low solubility in water. To overcome this, a biocompatible solubilization method is used to intensify the solubility of resveratrol. Hydrotropes (solubilizing agents) such as sodium caprylate, and sodium benzoate under a wide range of concentrations (0‒3 mol/L) and temperature (303–333 K) were used to study the aqueous solubility of resveratrol. It is observed that the solubility of resveratrol is enhanced by 16 times in the presence of sodium caprylate as hydrotrope. Thermodynamic properties like entropy, Gibbs free energy, and enthalpy were determined, and the solubilization process was found to be entropy-driven.

    Effective treatment and management of wastewater and solid waste are the major challenges growing at an alarming rate in today's world. The aim of the present study was to find the feasibility of utilizing agro-based waste (groundnut foliage) as a low cost adsorbent for dye laden waste water treatment.
  • Tribal plants and their inborn antimicrobial activities

    The importance of medicinal plants in traditional health-care practices provides clues to new areas of research and in the biodiversity of conservation. Right from the beginning, the documentation of traditional knowledge, especially on the medicinal uses of plants, has provided many important drugs for the modern day. Even today, this area holds much more hidden treasure as almost 80% of the human population in developing countries depend on plant resources for health care. Keeping this in view, the present study was initiated to document the traditionally used tribal plants and their inborn antimicrobial activity which is enhanced on the synthesis of noble metal nanoparticles.
