Abstract

Pada penetitian ini pembentukan kokristal asam usnat-N-methyl-D-glucamine bertujuan untuk meningkatkan kelarutan dan laju disolusi asam usnat serta uji efektivitasnya dalam kadar IL-8 pada tikus inflamasi. Kokristal asam usnat–N-methyl-D-glucamine dibuat dengan perbandingan 1:1 ekuimola dengan metode penguapan pelarut menggunakan etanol. Karakterisasi sampel dilakukan dengan difraksi sinar-X, Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR), dan Scanning Electron Microscopy (SEM). Evaluasi kokristal yang dilakukan mencakup uji kelarutan, uji laju disolusi, dan penentuan kadar interleukin-8 (IL-8) pada tikus inflamasi. Uji kelarutan dilakukan menggunakan pelarut air suling bebas CO2 sedangkan uji laju disolusi menggunakan media air suling bebas CO2 0.25% (b/v) sodium lauril sulfat (SLS), kedua larutan uji dianalisis menggunakan spektrofotometer UV-Vis. Pemeriksaan IL-8 tikus inflamasi menggunakan metode ELISA. Hasil karakterisasi difraksi sinar-X menunjukkan profil difraktogram yang berbeda dari komponen penyusun yang mengindikasikan terbentuknya fase kokristal. Hasil termogram DSC menunjukkan adanya puncak endotermik baru yang berbeda dengan kedua komponen penyusun. Spektrum FT-IR menunjukkan terjadinya pergeseran bilangan gelombang pada spektrum kokristal dibandingkan spektrum asam usnat dan N-methyl-D-glucamine. Analisis SEM menunjukkan perubahan morfologi partikel. Kelarutan dan laju disolusi kokristal meningkat secara signifikan (P<0,05) sebanyak 24 kali dan 23 kali dibandingkan dengan senyawa asam usnat murni. Kokristal dapat menurunkan kadar IL-8 pada tikus inflamasi yang setara dengan aktivitas antiinflamasi asetosal (P<0,05). Disimpulkan bahwa koristal asam usnat - N-methyl-D-glucamine dapat meningkatkan kelarutan, laju disolusi, dan menurunkan kadar IL-8 tikus inflamasi.

Abstract

Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID), one of the oxicam group. It is categorized as Biopharmaceutical Classification System class II, as its low solubility and high permeability. The aims of this research were to enhance the solubility and dissolution rate of tenoxicam by its modification into a co-amorphous phase with meglumine at a molar 1:1 ratio. The co amorphous form of tenoxicam-meglumine was prepared by a solvent drop grinding method, and characterized by thermal analysis using differential scanning calorimetry (DSC), solid phase by powder X-ray diffraction (PXRD), identification of functional group by Fourier-transform infrared (FT-IR) spectroscopy, and morphology by polarized light microscopy (PLM) and scanning electron microscopy (SEM). The solubility test was conducted in water, whereas the dissolution test was performed in 0.1 N HCl solution and water. The DSC thermogram demonstrated a decrease in the endothermic peak of the co-amorphous tenoxicam-meglumine. The PXRD diffractogram revealed a reduction in the peak intensity of the X-ray diffraction, which formed a halo pattern. The FT-IR spectroscopy analysis indicated the formation of the co-amorphous system. The co-amorphous of tenoxicam-meglumine solubility’s increased by 42.71-fold as compared to intact tenoxicam. The co-amorphous tenoxicam meglumine exhibited a dissolution rate of 92.71% and 100% in 0.1 N HCl and distilled water, respectively, after 60 minutes, and resulting in separate increases in dissolution efficiency by 3.05 and 9.12-times in 0.1 N HCl and distilled water. In summary, the formation of the co-amorphous phase of tenoxicam and meglumine successfully enhanced the solubility and dissolution of tenoxicam.

Abstract

Ticagrelor is a triazolopyrimidine antiplatelet agent with poor water solubility. Ticagrelor was incorporated into mesoporous silica SBA15 in this study to evaluate its physical stability and improve its solubility and dissolution rate. TEOS was employed as a silica precursor and Pluronic P123 as a template to synthesize SBA-15. Ticagrelor was loaded into SBA-15 at a mass ratio of 1:1. Physicochemical characterization was conducted using nitrogen adsorption-desorption isotherm analysis, powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC), fourier-transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). Ticagrelor solubility and dissolution were tested using distilled water as the medium. To evaluate the physical stability, Ticagrelor-SBA-15 was stored in a climatic chamber at 75% RH and 40°C for a month and analyzed using PXRD. Physicochemical characterization indicated efficient adsorption of ticagrelor into the SBA-15 pores, resulting in an amorphous form of solid material. Meanwhile, solubility and dissolution rate testing showed respective increases of 1.33 times and 1.74 times with significant differences (p<0.05) while maintaining its physical stability after storage for one month. Based on this study, it can be concluded that the incorporation of  mesoporous SBA-15 significantly enhances ticagrelor’s solubility and dissolution rate while maintaining stability.

Abstract

Indonesia is an important country that produces essential oils that are widely used in fragrance cosmetic products. The use of local essential oils for cosmetics needs to be introduced to the youth generation with the aim that they do not just become consumers. Youth organisations in Kerinci have many activities to improve their skills and abilities for a better future. Collaboration between the university and the youth organisation was achieved by providing training on doing cosmetic product training on making cosmetic products. The product uses essential oils called body mist. Nowadays, the youth still know very little about the manufacturing process of cosmetics products. To provide further benefits, this community service activity collaborated with BBPOM in Padang, West Sumatra, to explain cosmetic safety and the registration process of cosmetic products. With this series topic in this training and outreach-related cosmetics, it is hoped that it can increase business ideas for young people who are members of the Sakti Alam Kerinci Organisation.

Abstract

Gliclazide (GLI), a sulfonylurea-class antidiabetic drug, exhibits poor aqueous solubility, limiting its bioavailability. This study aimed to enhance gliclazide’s solubility and dissolution rate by adsorbing it into mesoporous silica SBA-15 and amine-functionalized SBA-15 (SBA-15-A). SBA-15 was synthesized using Pluronic® P123 as a template and tetraethyl orthosilicate (TEOS) as the silica precursor, while 3-aminopropyltriethoxysilane (APTES) was used to introduce amine functional groups. Gliclazide was loaded into SBA-15 and SBA-15-A at a 1:3 mass ratio. The materials (GLI, SBA-15, SBA-15-A, GLI-SBA, and GLI-SBA-A) were characterized using nitrogen adsorption-desorption isotherms, differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and powder X-ray diffraction (PXRD). Characterization revealed that the pore diameters of SBA-15 and SBA-15-A were 6.079 nm and 5.483 nm, respectively. FT-IR confirmed the interaction between gliclazide and the mesoporous carriers. SEM and TEM analysis showed crystalline gliclazide and rod-shaped morphologies for the mesopores samples. DSC and PXRD results indicated that most of the gliclazide had been converted to an amorphous form. Solubility testing over 24 hours showed that GLI-SBA and GLI-SBA-A improved gliclazide solubility by 1.375- and 2.334-fold, respectively, compared to pure gliclazide. Dissolution testing in distilled water revealed a 6.033-fold and 3.887-fold increase in the release rate at 5 minutes for GLI-SBA and GLI-SBA-A, respectively. Both solubility and release rate improvements were statistically significant (p <0.05). These findings suggest that amine functionalization of SBA-15 effectively enhances the solubility and dissolution rate of gliclazide.

Abstract

Aceclofenac is a phenylacetic acid derivative classified as a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain caused by inflammation. It has potential for topical application through a transdermal delivery system. One promising approach is the use of liquid crystals as carriers in transdermal dosage forms. This study aims to develop a simple liquid crystal cream formulation for aceclofenac, using glyceryl monostearate as a mesogen and Pluronic as a stabilizer. The aceclofenac liquid crystal cream was characterized using Polarized Light Microscopy (PLM), Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy (ATR-FTIR), and Differential Scanning Calorimetry (DSC). Evaluations included drug release, permeation, viscosity, flow properties, zeta potential, and freeze-thaw stability. The optimal formulation consisted of oil: glyceryl monostearate–Pluronic P123: water in a 5:15:80% ratio. PLM results showed birefringence and a lamellar phase texture. FTIR analysis confirmed no new chemical bonds, while DSC indicated a reduced melting point and increased enthalpy of fusion. The release and permeation of aceclofenac after 6 hours were 27.849 ± 0.5479 µg/cm² and 21.093 ± 0.5761 µg/cm², respectively—higher than non-liquid crystal preparations. The cream exhibited thixotropic flow behavior, a zeta potential of -50.8 mV, and remained stable after six freeze-thaw cycles. In coclusion, Aceclofenac can be formulated into a liquid crystal cream with glyceryl monostearate as a mesogen, showing a birefringent lamellar phase that enhances its release and permeation
