[ Description ]
Dalam sistem penghantaran obat (drug delivery system), kemampuan untuk mengontrol ukuran, morfologi dan drug release suatu partikel obat merupakan hal yang mendasar. Karakterisitik obat yang unggul sangat penting untuk memastikan jumlah bioaktif yang dihantarkan sesuai dengan yang diperlukan oleh tubuh. Penelitian ini bertujuan untuk memperoleh mikro-komposit zat terapeutik-polimer dengan teknologi Particles from Gas-Saturated Solutions (PGSS). Telah dipelajari pengaruh tekanan dan temperatur operasi dalam saturation vessel dari penambahan PLA dalam pembentukan struktur komposit zat terapeutik-polimer. Ketoprofen dan PEG 6000-PLA disaturasi terlebih dahulu dengan bantuan fluida-CO2 superkritis kemudian diekspansikan melalui nozzle. Mikropartikel yang terbentuk kemudian dianalisa morfologinya dengan menggunakan Scanning Electron Microscopy (SEM) serta dianalisa ukuran dan distribusi ukurannya dengan menggunakan particle counter. Selain itu dilakukan uji drug loading untuk mengetahui perolehan kembali ketoprofen hasil mikronisasi, dan drug release untuk mengetahui efek pembentukan mikropartikel komposit terhadap performa penghantaran. Pada penelitian ini diperoleh kesimpulan bahwa tekanan saturation vessel berpengaruh pada variasi struktur komposit yang keluar dari nozzle. Diameter rata-rata komposit yang dihasilkan antara 4,53-79,42 µm. Sedangkan uji drug loading menunjukkan efisiensi drug loading untuk komposit berkisar antara 62,08-97,15%. Dan uji drug release menunjukkan bahwa komposit ketoprofen-PEG 6000-PLA memiliki laju disolusi lebih tinggi dibandingkan dengan ketoprofen tanpa mikronisasi, pada komposisi 1:3 5% PLA/PEG, 1:8 5% PLA/PEG dan 1:8 10% PLA/PEG, sedangkan uji drug release yang menunjukkan bahwa komposit ketoprofen-PEG 6000-PLA memiliki laju disolusi lebih rendah dibandingkan dengan ketoprofen tanpa mikronisasi, pada komposisi 1:3 10% PLA/PEG, 1:5 5% PLA/PEG, 1:5 10% PLA/PEG.
Alt. Description
In drug delivery systems, the ability to control the size, morphology and drug release of a drug particle is fundamental. Superior characteristics of the drug is vital to ensure the amount of bioactive delivered in accordance with that required by the body. This study aims to obtain micro-therapeutic agent-polymer composite technology with particles from Gas-Saturated Solutions (PGSS). Have studied the influence of pressure and temperature vessels operating in the saturation of the addition of PLA in the formation of the composite structure of polymer-therapeutic agent. Ketoprofen and PEG 6000-PLA are saturated advance with the help of supercritical fluid-CO2 and then expanded through a nozzle. Microparticles are formed and then analyzed the morphology using Scanning Electron Microscopy (SEM) and analyzed the size and size distribution using a particle counter. In addition to drug-loading test was conducted to determine the recovery of ketoprofen micronisation results, and drug release to determine the effects of the formation of composite microparticles on delivery performance. In this study the conclusion that the pressure vessel saturation effect on the variation of composite structures is out of the nozzle. Average diameter of the resulting composites between 4.53 to 79.42 μm. While loading the drug test showed the efficiency of drug loading for the composites ranged from 62.08 to 97.15%. And the drug release test showed that the composite ketoprofen-PEG 6000-PLA has a higher dissolution rate compared with ketoprofen without micronisation, at 1:3 composition of 5% PLA / PEG, 1:8 5% PLA / PEG 1:8 and 10% PLA / PEG, whereas the drug release test showed that the composite ketoprofen-PEG 6000-PLA has a lower dissolution rate compared with ketoprofen without micronisation, at 1:3 composition of 10% PLA / PEG, 1:5 5% PLA / PEG, 1:5 10% PLA / PEG.
