Abstract

Etoricoxib (ETX) is a selective COX-2 anti-inflammatory drug classified in BCS class II. This study aims to enhance the dissolution rate of etoricoxib through a combination of co-crystal formation and ball milling conducted in-situ and ex-situ. Optimization was done by varying milling times and types of stabilizers, including Tween 80 (ETX-OXA-BM-T), Poloxamer 188 (ETX-OXA-BM-P), and a combination of Tween 80-sodium lauryl sulfate (SLS) (ETX-OXA-BM-T-S). In-situ experiments yielded a very low yield (<10%) and failed to produce co-crystals, thus deeming them unsuitable for continuation. Meanwhile, the ex-situ process showed more potential, leading to further evaluation using Differential Scanning Calorimetry (DSC), Powder X-Ray Diffractometry (PXRD), and Scanning Electron Microscope (SEM). DSC analysis showed endothermic peaks at 130°C for ETX and around 179 - 180°C for ETX-OXA and its derivatives. PXRD diffractograms for ETX-OXA and its derivatives exhibited similar peaks, differing from ETX. SEM analysis indicated that ETX-OXA-BM-T with 60 minutes of milling resulted in nanometer-sized particles, while the use of Poloxamer 188 and the combination of Tween 80-SLS produced particle sizes > 1 µm. ETX-OXA-BM-T showed the highest increase in solubility in all media. The dissolution results of ETX-OXA-BM-T showed improvement in phosphate buffer pH 6.8, while no significant differences were observed in pH 1.2 and 4.5 buffers. This study demonstrates that the combination of co-crystal formation and ex-situ ball milling is a potential approach to enhancing the dissolution rate of etoricoxib.

Abstract

Tablet production is a very intricate process influenced by numerous process variables or parameters. This study aimed to identify the critical processing variables that affect Critical Quality Attributes (CQAs) of vitamin C film-coated caplets utilizing a statistical experimental design. A two-level complete factorial design with two central points was used to examine the process parameters that posed the greatest risk to CQAs. The process variables investigated included mesh size and duration for the lubrication process, as well as speed and main thickness for compression. Statistical results showed that mesh number, lubrication time, and their interaction significantly affect flow rate, Hausner ratio, and compressibility index. Higher mesh number and longer duration improved flow properties; lower main thickness significantly increased core caplet hardness; and lower dissolution rates were observed at higher compression speeds. Based on this study, it can be concluded that mesh number and lubrication time only significantly affected the bulk quality attributes but did not have a significant impact on the quality attributes of vitamin C caplets. On the other hand, the parameters of the compression process, such as speed and main thickness, greatly impacted the quality attributes of vitamin C caplets. In this study, the use of mesh number 20 with 7 minutes of lubrication, and a speed of 17 rpm with a main thickness scale of 2.00 were determined as the optimal process parameters. The optimal process parameters for the lubrication and compression processes were obtained from statistical analysis of the response data.

Abstract

Vitamin C dalam bidang kosmetik memiliki banyak manfaat termasuk sebagai antioksidan. Akan tetapi sediaan vitamin C mudah teroksidasi dan mengalami perubahan warna sehingga perlu ditambahkan penstabil yang mampu menjaga kestabilan vitamin C selama pemakaian dan penyimpanan. Penelitian ini bertujuan untuk mengetahui pengaruh hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer  dan natrium metabisulfit  terhadap karaktiristik emulgel vitamin C serta menentukan formula emulgel yang optimum melalui pendekatan Design of Experiment (DOE) dengan metode  Simplex Lattice Design. Hasil penelitian menunjukkan bahwa variabel konsentrasi hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer  dan natrium metabisulfit  memberikan pengaruh yang signifikan terhadap viskositas (P<0,05), pengujian kesukaan aroma (P<0,05), pengujian tekstur (P<0,05) dan kestabilan formula (P<0,05). Akan kedua bahan tersebut tetapi tidak berpengaruh secara signifikan terhadap nilai pH (P>0,05). Formulasi optimum dihasilkan dengan penambahan adalah 2,305% hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer  dan 0,194 % natrium metabisulfit  dengan nilai desirability 0,633. Formula ini  memenuhi kriteria sediaan yang cukup baik, namun perlu dilakukan perbaikan aroma untuk meningkatkan penilaian kesukaan.

Abstract

Etoricoxib merupakan salah satu golongan anti inflamasi selektif COX-2 yang diklasifikasikan dalam BSC kelas II. Pada penelitian ini dilakukan usaha peningkatan kelarutan etoricoxib melalui metode dispersi padat dengan menggunakan Kollidon® VA 64. Percobaan ini diawali dengan uji pendahuluan untuk mencari optimasi perbandingan antara etoricoxib dengan Kollidon® VA 64. Setelah dilakukan uji didapatkan perbandingan ETO-KOL-3 (1:3) adalah yang optimal. Kemudian dilakukan pembuatan dispersi padat dengan menggunakan metode penguapan pelarut yang terbagi tiga yaitu pengeringan pelarut pada suhu ruang, pengeringan pelarut dengan laju pemanasan dan pengeringan pelarut dengan Spray Drying. Hasil dispersi padat kemudian dikarakterisasi dengan Powder X-Ray Diffractometry (PXRD), Differensial Scanning Calorimetry (DSC) dan Scanning Electron Microscope(SEM). Hasil PXRD dari ETO-KOL-3-SR, ETO-KOL-3-SE dan ETO-KOL-3-SD memiliki derajat kristalinitas sebesar 37,62, 36,72 dan 35,55. Hasil DSC ETO-KOL-3-SR, ETO-KOL-3-SE dan ETO-KOL-3-SD memiliki Tg sebesar 72,78, 80,87 dan 88,48°C. Hasil SEM ETO-KOL-3-SR dan ETO-KOL-3-SE memiliki bentuk lempeng irregular tetapi ETO-KOL-3-SD memiliki bentuk spherical. Hasil disolusi ETO-KOL-3-SR, ETO-KOL-3-SE dan ETO-KOL-3-SD pada media dapar fosfat pH 6,8 memiliki persen disolusi 53,39±0,34 %, 63,05±0,24% dan 72,60±0,19%.

Abstract

The electrospinning method has been used successfully to make polyvinylpyrrolidone nanofiber containing Anredera cordifolia leaves (BLE). The research methods used were qualitative and pure experiment method. Polyvinilpirolidone nanofibers containing BLE were prepared with three mass variations of the polyvinylpyrrolidone (% w/w), namely 12%, 10%, and 8% w/w, respectively. The results of the macroscopic photo show that the fiber structure looks white for PVP nanofibers and yellow for PVP/BLE nanofibers. The fiber morphology was analyzed using SEM and the results showed that PVP and all PVP/BLE nanofibers were like a continuous strand of crossbars with a diameter of 590 – 1190 nm. The decrease in the concentration of the PVP polymer led to a reduction in the diameter of the resulting nanofibers. The coefficients of variance (ε), of the PVP, BLE1, BLE2, and BLE3 nanofibers were 0.06, 0.09, 0.11, and 1.22, respectively. The physicochemical structure of the nanofibers was evaluated using XRD and FTIR. The chemical analysis (FTIR) showed that there was a molecular interaction between Anredera cordifolia leaves extract and polyvinylpyrrolidone in the form of hydrogen bonds. The physics analysis (XRD) shows the effect of the electrospinning process, which is to change the structure of BLE crystals to semi crystals. The application of PVP/BLE nanofiber for wounds dressing

Abstract

Bromo acid dye (Red 21) recently gained attention in the production of color-changing cosmetics. The critical aspect in the development of cosmetic products using this dye group is the compatibility of its oil vehicles. The compatibility of bromo acid dyes with oil vehicles is determined by several parameters such as the dye solubility in the oils, clarity of the mixture, and the ability to change color when the pH of the solution is adjusted to match the skin’s pH. Therefore, this study conducted the compatibility study by examining the ability of 27 oil samples to dissolve Red 21. The ability of a vehicle to dissolve a compound is influenced by the polarity of the vehicle. Hence, a correlation was established between the relative polarity of oils and their ability to dissolve Red 21. The results showed that the water-oil interfacial tension was negatively correlated (r = -0.64) with Red 21 solubility in the oil. From this research, the water-oil interfacial tension represented the relative polarity of the oil and was considered sufficient to predict the compatibility of the oil with Red 21. In addition, hydrocarbon and silicone oils are not compatible with Red 21.
