Abstract

Dengue hemorrhagic fever (DHF) is a serious mosquito-borne disease caused by the dengue virus, most often transmitted by the bite of female Aedes aegypti mosquitoes. In Indonesia, the number of DHF cases has steadily increased since the disease was first reported, underscoring the urgent need for effective treatments. This study used in silico methods to explore the potential of three bioactive compounds from Cinnamomum zeylanicum i.e. cinnamaldehyde, α-terpineol, and chavicol as inhibitors of the dengue virus NS2B/NS3 protease and evaluated their drug-likeness and potential toxicity. The compounds sourced from the NADI database were compared with panduratin A as a positive control. Molecular docking was performed using the Molecular Operating Environment (MOE) 2023.0901 software, and drug-likeness and toxicity predictions were performed using SwissADME and Protox-II. Among the tested compounds, α-terpineol exhibited the strongest potential to inhibit NS2B/NS3, while all three met the standard drug-likeness criteria. Notably, α-terpineol demonstrated the most favorable safety profile compared to cinnamaldehyde, chavicol, and panduratin A.

Abstract

Fenofibrate acid is a fibrate drug with high permeability but low water solubility, resulting in limited bioavailability. Solid dispersion using hydrophilic carriers is one strategy to increase solubility. The objective of this study was to improve the solubility of fenofibric acid by converting it into a solid dispersion system using PEG 6000 as a carrier. Preparation of solid dispersion systems by the melting method. The fenofibric acid PEG 6000 weight ratios were F1 (1:1), F2 (1:3), and F5 (1:5). Physicochemical characterization of the solid dispersions included DSC, PXRD, FTIR, and SEM tests, as well as dissolution and bioavailability tests with the determination of pharmacokinetic parameters. Characterization results show that fenofibric acid with PEG 6000 as a carrier still exhibits a crystalline phase but with reduced intensity, resulting in increased solubility and dissolution rate. Dissolution test show that solid dispersion F3 (1:5) dissolves faster (78.7%) than pure fenofibric acid (53.2%). after 60 minutes. Pharmacokinetic parameter determination tests showed no significant difference between pure fenofibric acid and solid dispersion. Solid dispersion of fenofibric acid with PEG 6000 as a carrier can improve the physicochemical performance and dissolution rate of fenofibric acid but pharmacokinetic parameters did not differ significantly.

Abstract

Penyimpanan obat merupakan salah satu bagian penting dalam pengelolaan perbekalan farmasi yang bertujuan menjaga mutu, keamanan, serta ketersediaan obat agar tetap layak digunakan. Penyimpanan yang baik juga berperan dalam mencegah kerusakan, kehilangan, penyalahgunaan, dan memudahkan proses pencarian maupun pengawasan sediaan farmasi. Penelitian ini bertujuan untuk mengetahui gambaran penyimpanan obat di Apotek “X” Kota Pekanbaru Tahun 2026 berdasarkan Petunjuk Teknis Standar Pelayanan Kefarmasian di Apotek. Metode penelitian yang digunakan adalah observasional dengan pendekatan deskriptif. Pengumpulan data dilakukan melalui wawancara dan observasi langsung terhadap sistem penyimpanan obat di apotek. Data yang diperoleh dianalisis secara deskriptif dan disajikan dalam bentuk tabel. Hasil penelitian menunjukkan bahwa penyimpanan obat di Apotek “X” telah menggunakan rak atau etalase sebagai tempat penyimpanan. Penataan obat dilakukan berdasarkan urutan alfabetis, bentuk sediaan, dan indikasi obat. Obat yang mengandung prekursor disimpan secara terpisah dari golongan obat lainnya. Suhu penyimpanan obat disesuaikan dengan ketentuan yang tertera pada kemasan, sedangkan obat dengan penyimpanan khusus ditempatkan di dalam kulkas. Sistem pengeluaran obat menggunakan metode First Expired First Out (FEFO). Namun, masih ditemukan ketidaksesuaian pada penyimpanan obat Look Alike Sound Alike (LASA) dan high alert yang masih disimpan berdekatan dengan obat lain serta belum seluruhnya diberi label khusus. Penyimpanan obat kedaluwarsa telah dilakukan secara terpisah sebelum dimusnahkan.
