STUDI IN-VITRO IBUPROFEN TERSALUT ALGINAT-KITOSAN
Abstract
ABSTRAK: Kompleks alginat-kitosan digunakan sebagai material pembawa obat ibuprofen yang dibuat dengan menggunakan metode emulsi water in oil (W/O). Karakterisasi dilakukan terhadap kompleks yang telah dibuat. Karakterisasi dilakukan untuk mengetahui panjang gelombang maksimum, morfologi enkapsulasi, dan efisiensi enkapsulasi. Uji disolusi terhadap berbagai variasi konsentrasi kompleks alginat-kitosan dilakukan untuk mengetahui efek pelepasan ibuprofen tersalut alginat-kitosan. Hasil penelitian menunjukkan serapan maksimum terjadi pada ? = 221,8 nm. Keseragaman pori yang berukuran kecil, sebaran yang merata dan efisiensi enkapsulasi yang paling baik = 87,19% ditunjukkan pada Alg-Chi dengan perbandingan 8:2. Hasil uji disolusi menunjukkan pelepasan maksimum ibuprofen terjadi pada menit ke-15.

ABSTRACT: Alginate-chitosan complex is used as a carrier material for ibuprofen which is made using the water in oil (W/O) emulsion method. Characterization is carried out on complexes that have been made. Characterization was carried out to determine the maximum wavelength, morphology of encapsulation and encapsulation efficiency. Dissolution test on various concentrations of alginate-chitosan complex was carried out to determine the effects of alginate-chitosan coated coating ibuprofen. The results showed the maximum absorption occurred at ? = 221.8 nm. Small pore uniformity, even distribution and the best encapsulation efficiency = 87.19% is shown in Alg-Chi with a ratio of 8:2. Dissolution test results showed the maximum release of ibuprofen occurred at 15 minutes.
