Abstract

The purpose of this work was to explore the formation of ketoprofen-malonic acid cocrystal by solvent evaporation method. Early detection of cocrystal formation was conducted by hot stage microscopy and solid-liquid phase diagram. Cocrystal were prepared by solvent evaporation method by using isopropyl alcohol as solvent. Characterization of cocrystal was done by Powder X-Ray Diffractometry (PXRD), Differential Scanning Calorimetry (DSC), Fourier Transform Infrared (FTIR) Spectroscopy and Scanning Electron Microscopy (SEM). The results of hot stage microscopic and solid-liquid phase diagram indicated formation of ketoprofen-malonic acid cocrystal. PXRD and DSC measurements showed stoichiometric ratio of cocrystal ketoprofen-malonic acid (2:1). The ketoprofen-malonic acid cocrystal had melting point at 86.2 °C and unique peaks of PXRD pattern at 2θ of 6.1°, 17.8°, 23.2° and 28.6°. FTIR spectra indicated the formation of cocrystal due to interaction of C=O ketone group of ketoprofen with MA molecule. SEM images show that ketoprofen-malonic acid cocrystal have multi-shaped particles with rough surfaces.

Abstract

The aim of the study was to improve the in-vitro dissolution rate of quercetin (Qu) using cocrystallization of quercetin. Cocrystals of quercetin (Co Qu) were produced with malonic acid (Ma) as coformer at ratio 1:2 using solvent evaporation method. Cocrystals quercetin-malonic acid (Co Qu-Ma) was characterized using Differential Thermal Analysis (DTA), Powder X-Ray Diffraction (PXRD), Scanning Electron Microscope (SEM), and Fourier Transforms Infrared Spectrophotometer (FTIR) and in-vitro dissolution study. A new endothermic peak at 277.9 °C was shown from the thermogram. Diffractogram of Co Qu-Ma showed a new diffraction peak at 2θ 9.81, 12.99, and 19.80°. Microphotograph showed that Qu and Ma exhibited a columnar-shaped and a pebble-shaped crystal, respectively, and FTIR wavenumber of O-H functional group of quercetin was shifted from its original position at 3411 to 3428 cm-1 in the physical mixture (pm) of Qu-Ma and 3418 cm-1 in Co Qu-Ma, respectively. The physicochemical characterizations using DTA, PXRD, SEM and FTIR indicated that Co Qu-Ma were successfully obtained through solvent evaporation method. The in-vitro dissolution rate of Co Qu-Ma was 95.30% at 60 min. Cocrystals effectively increased dissolution rate and dissolution efficiency in comparison to the pure quercetin and physical mixture of quercetin-malonic acid.

Abstract

Atorvastatin calcium is a statin drug used for antihypercholesterolemic. The oral bioavailability of atorvastatin calcium is relatively low because it is poorly soluble in water. The low oral bioavailability of the drug causes a decrease in its therapeutic effectiveness. This study aimed to increase the solubility of atorvastatin calcium through the formation of co-amorphous solids and evaluate its activity as antihypercholesterolemic. Atorvastatin calcium was prepared into co-amorphous solids with a maleic acid coformer using the spray drying method. Solids characterization was carried out using Powder X-Ray Diffraction (PXRD), Differential Scanning Calorimetry (DSC), Fourier Transforms Infra Red (FTIR), and Scanning Electronic Microscopy (SEM). The solubility test was carried out using the shaking method, while the evaluation of antihypercholesterolemic was carried out in vivo in experimental animals. The results of the analysis of diffractograms, thermograms, FTIR spectra, and micrograph images showed that the atorvastatin calcium-maleic acid solids prepared by spray drying were a co-amorphous solid. The atorvastatin calcium-maleic acid co-amorphous solids had a greater solubility in water (p<0.05) when compared to pure atorvastatin calcium. However, the in vivo antihypercholesterolemic activity results in experimental animals showed that the cholesterol-lowering activity of the atorvastatin calcium-maleic acid co-amorphous solidswas not significantly different (p>0.05) with pure atorvastatin calcium. This phenomenon is thought to be because atorvastatin calcium from co-amorphous solids in solution is more present as a charged fraction, affecting the permeability and absorption process.

Abstract

The Co-crsytal formation ketoconazole (KTZ) - succinic acid (SA) has been performed by molar ratio (1:1) using milling method (grinding).. Milling is done using Planetary Ball mill PM 200 MA-type tool, Retsch with 75 rpm milling speed. The physical mixture of KTZ and AS molar ratio (1:1) was prepared in the absence of a dry grinding solution with milling time of 5, 15, 30, 45 and 60 min at a constant velocity. The milling results are seen by using powder X-ray diffraction (PXRD) at an angle (2θ = 7.8o). From the results of X-ray powder diffraction there is an increase in the percentage of crystalline (% w/w). The result of the grinding time curve with the percentage of crystal (%w/w), the result that the percentage of crystalline (% w/w) increases linearly with increasing milling time (min) based on the maximum intensity data of each milling time by the line equation (y = 0.690x + 51.09) and correlation coefficient r = 0.9905. As conclusion, based on kinetic formation of cocristal with milling method obtained for slope value = 0,690 % cocrystall (%b/b)/min.

Abstract

Curcumin (CUR) is a polyphenolic compound that exhibits potent anti-inflammatory activity. However, only a tiny amount of CUR is absorbed during oral administration, which is because CUR is difficult to dissolve in water. The aim of the research was to increase the solubility of CUR through the cocrystallization technique using isonicotinamide coformer (INIC) by solvent evaporation. Cocrystal characterization was carried out using a powder X-ray diffractometer (PXRD), a differential scanning calorimeter (DSC), a Fourier transform infrared spectrometer (FTIR), and a scanning electron microscope (SEM). Solubility was evaluated using the shaking method, while the anti-inflammatory activity test was carried out using the carrageenan induced mouse leg edema method. The resulting CUR-INIC (1:1) cocrystal has a diffractogram with new diffraction peaks of 2theta at 15.00, 16.22, and 22.89◦ compared to the individual diffractograms of CUR and INIC. In the cocrystal, CUR and INIC form intermolecular interactions of hydrogen bonds, resulting in a new solid phase with a melting point of 160.1◦C. The solubility of the CUR-INIC cocrystal in water was 73.1±0.23 ug/mL, which increased 14 times compared to the solubility of initial CUR, which was only 5.05±0.07 ug/mL. The CUR-INIC cocrystal showed a percentage of edema inhibition in mice (5 hours) 130% more potent than that of initial CUR. Therefore, CUR-INIC cocrystals can be used to improve CUR solubility to obtain more excellent anti-inflammatory effects.

Abstract

Tingkat pelanggaran siswa pada SMA Negeri 1 Purwosari dari tahun ke tahun terus bertambah dengan berbagai macam pelanggaran yang dilakukan. Selama ini pencatatan poin pelanggaran yang dilakukan oleh guru BK (Bimbingan Konseling) menggunakan buku tatib yang dimiliki oleh sekolah. Pengendalian pada pelanggaran yang dilakukan masih belum dapat dilakukan secara optimal karena guru BK (Bimbingan Konseling) tidak dapat dengan mudah menentukan tingkat tertinggi pelanggaran yang dilakukan oleh siswa. Karena itulah sebuah sistem pencatatan poin pelanggaran siswa pada sekolah sangat diperlukan untuk mengetahui tingkat ketidak disiplinan para siswa dalam lingkungan sekolah. Sistem informasi tersebut juga dapat menghasilkan informasi tersebut secara efektif dan efisien. Sistem pencatatan pelangaran ini menggunakan metode penjumlahan dari tiap komponen pelanggaran yaitu komponen sikap dan perilaku, komponen kerajinan dan komponen kerapian, sehingga nanti didapatkan jumlah point dari tiap siswa beserta sanksi yang didapat dan jumlah statistik pelanggaran yang dilakukan oleh siswa. Dengan demikian sistem pencatatan poin pelanggaran ini dapat menjadi pendukung keputusan bagi guru BK yang memberi penilaian terhadap pelanggaran siswa di lingkungan sekolah.
