Abstract

Usnic acid, a secondary metabolite of lichen Usnea sp., has several pharmacological activities, but it is poorly soluble in water. This study aimed to improve the solubility and dissolution rate of usnic acid loaded in mesoporous silica SBA-15 at a mass ratio of 1:1. and evaluate its physical stability. Physicochemical characterization was carried out via the nitrogen adsorption desorption isotherm, differential scanning calorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, and powder X-ray diffraction (PXRD). Usnic acid-loaded SBA-15 was stored at 40 °C with various relative humidities (RH) and then analyzed by PXRD for the physical stability. Usnic acid adsorbed well in the pores of SBA-15, as shown by a decrease in the volume pore and surface area of SBA-15 according to the nitrogen adsorption. Moreover, usnic acid-SBA-15 showed a decrease in the degree of crystallinity according to PXRD analysis and no melting point based on DSC analysis. The FTIR spectrum of usnic acid–SBA-15 corresponds to the spectra of each raw material. The solubility of usnic acid increased 5.15 times after adsorbed on SBA-15. The dissolution rate also showed a significant increase (p < 0.05) from 19.51% to 84.27%. Usnic acid–SBA-15 was relatively stable at RH 75%. Thus, the adsorption of usnic acid on SBA-15 can increase its solubility, dissolution rate, and physical stability.

Abstract

Ketoprofen is a non-steroidal anti-inflammatory drug (NSAID) whose formulation options are limited due to its low dissolution rate in aqueous media. This research aimed to enhance the solubility of ketoprofen in distilled water and to compare the anti-inflammatory and analgesic effects of its resulting multicomponent crystal with tromethamine. The binary phase diagram of ketoprofen-tromethamine was created across molar ratios ranging from 1:9 to 9:1. The multicomponent crystal comprising ketoprofen and tromethamine in the selected ratio was synthesized using a solvent drop grinding method and subjected to further characterization for thermal properties, crystallinity, chemical groups, and morphology. The dissolution rate assessments were evaluated in CO2-free distilled water. Pharmacological analyses examined the anti-inflammatory and analgesic effects of the multicomponent crystal. The binary phase analysis identified the 5:5 (1:1) molar ratio as optimal in forming a multicomponent crystal. Thermograms and diffractograms revealed crystalline alterations attributed to a new crystalline phase. The new multicomponent crystal exhibited approximately 2.7 times higher dissolution rate after 30 minutes, outperforming pure ketoprofen. Pharmacological assessments demonstrated superior analgesic effects of the multicomponent crystal. In summary, the ketoprofen-tromethamine cocrystal in 1:1 molar ratio offers enhanced dissolution rate and provides better analgesic activity than ketoprofen alone.
