AI Article Synopsis
- Research focused on creating granules that mask the bitter taste of diphenhydramine hydrochloride (DPH) for easy consumption in instant jelly forms.
- The study found that ι-carrageenan was the most effective polymer for suppressing the bitterness of DPH due to its unique structure and interactions with the drug.
- The resulting instant jelly formulation, made with ι-carrageenan, met texture specifications for patients who struggle with swallowing, while effectively reducing the bitterness of the medication.
Article Abstract
This study developed easy-to-consume bitter taste-masking granules for the preparation of instant jelly formulations. Composite granules containing diphenhydramine hydrochloride (DPH) and polymers were prepared via spray drying. The taste-masking effect on DPH was evaluated with acceptable linearity between DPH concentration and intensity of bitterness using an electronic tongue sensor. The results indicated that ι-carrageenan could provide the greatest suppression effect on the DPH bitterness among the polymers selected for preparing spray-dried particles (SDPs). The thixotropic index (TI) of ι-carrageenan was higher than that of the other polymers. In addition, two sulfate groups per two galactose molecules in one unit of ι-carrageenan improved interaction with DPH. Compared to κ-carrageenan, the electrostatic interaction with DPH may be stronger. Easy-to-consume SDPs with ι-carrageenan were used to prepare instant jelly formulations. The instant jelly formulation containing DPH with ι-carrageenan (3.0%) met the criteria for texture properties (hardness, adhesiveness, and cohesiveness) for patients with difficulty swallowing, as specified by the Consumer Affairs Agency. Furthermore, instant jelly enhanced the bitter taste suppression of DPH. Overall, using spray-dried granules with ι-carrageenan, this technique for preparing instant jelly formulations is simple and inhibits the bitter taste of drugs, contributing to the development of oral dosage forms suitable for patients of all ages.

Dynamic silicone hydrogel gauze coatings with dual anti-blood adhesion mechanism for rapid hemostasis and minimal secondary damage.

Hemostatic materials that can rapidly control bleeding without causing secondary damage or sharp pain upon removal are receiving increasing demands in acute trauma treatments and first-aid supplies. Here, we report the development of a dynamic silicone hydrogel coating on medical gauze to enable rapid hemostasis and synergistic anti-blood adhesion properties. The silicone hydrogel can spontaneously form oriented cross-linked structures on fibrous medical gauze through a solution-processing method to achieve macroscopic superhydrophobicity with microscopic surface slipperiness, resulting in excellent anti-blood adhesion with the on-wound peeling force at ~0 millinewton.

The emergence of drug-resistant bacteria poses significant challenges in wound treatment. Antimicrobial photodynamic therapy has emerged as an effective approach to eliminating bacteria by inducing oxidative stress without causing drug resistance. Here, we developed a natural hyaluronic acid (HA)-gallic acid (GA) conjugation-based hydrogel combined with herbal photosensitizer-caffeic acid (CA), which exhibits self-healing ability, shape adaptability, biodegradability, and robust tissue adhesion.

Enhancing the sensory appeal of jasmine instant tea, particularly its aroma, poses a significant challenge due to the loss of volatile organic compounds during conventional processing. This study introduces a novel approach to address this issue through the application of microencapsulation techniques, aimed at preserving these key aromatic elements. Our investigation focused on the encapsulating agents gelatin, acacia gum, carboxymethylcellulose (CMC), and maltodextrin, chosen for their compatibility with the volatile organic compounds of tea.
