- Interactive mixtures give advantages for the mixtures containing low dose drug such as prednisone as it guarantee homogeneity, stability and increase the dissolution of prednisone. Flowability and compactibility of the interactive mixtures are relatively good, it can be directly compressed to produce tablet. The addition of lubricant / glidant of Mg stearat , talc or their mixture as the cohesive materials to the prednisone-granule interactive mixtures produce prednisone- granule-lubricant/ glidant which affect the tablet properties such as disintegration time and release of the drug. Based on these matter, a study was done to examine effect of Mg stearat, talc or their mixtures to the disintegration time and dissolution of prednisone interactive mixtures tablet. For the investigation of these effects, experiments were done using optimization approach based on simplex lattice design with Mg stearate and talc as the independent variable. The experiments data were implemented into the equation relation to the simplex lattice design : Y= a(A) + b (B) + ab (A) (B). Based on the coefficient value of the disintegration time and drug dissolution equations, profiles are made, lubricant/glidant effects on the disintegration time and drug dissolution can be analyzed. Magnesium stearate cause prednisone interactive mixtures disintegration time tablet are more longer than talc, although the affect interaction is relativity more little. Magnesium stearate compared with talc gives C30 value and DE-60, although the interaction gives affect relativity more little.
- Campuran interaktif memberikan keuntungan untuk campuran yang mengandung obat berdosis rendah seperti prednison, karena dapat menjamin homogenitas, stabilitas serta mempercepat disolusi obatnya. Sifat alir dan kompaktibilitas campuran relatif baik, sehingga dapat dibuat tablet secara kempa langsung. Penambahan bahan pelicin magnesium stearat, talk atau campurannya sebagai material kohesif pada campuran interaktif prednison-granul akan menghasilkan campuran interaktif prednison-granul-pelicin, akan berpengaruh pada sifatsifat tablet seperti waktu hancur serta pelepasan obat yang dikandungnya. Berdasarkan hal tersebut dilakukan penelitian untuk mengetahui pengaruh magnesium stearat, talk atau campurannya terhadap waktu hancur dan disolusi tablet campuran interaktif prednison. Untuk mengetahui pengaruh tersebut dilakukan percobaan dengan pendekatan optimasi berdasarkan simplex lattice design dengan variabel bebasnya magnesium stearat dan talk. Data percobaan diimplementasikan ke dalam persamaan terkait simplex lattice design yaitu Y = a (A) + b (B) + ab (A) (B). Berdasarkan nilai koefisien dalam persamaan untuk waktu hancur tablet dan disolusi prednison kemudian dibuat profilnya, dapat dianalisa pengaruh masing-masing bahan pelicin terhadap waktu hancur tablet dan disolusi obatnya. Magnesium stearat menyebabkan waktu hancur tablet campuran interaktif prednison lebih lama daripada talk, sedangkan pengaruh interaksinya relatif kecil. Magnesium stearat dibandingkan dengan talk memberikan nilai C30, dan DE-60 yang lebih besar, sedangkan interaksinya memberikan pengaruh yang relatif kecil.
