Dissolution Profile of Sustained Release Tablet of Diclofenac Sodium Using Metolose 90 SH 4000 Matrix

Natrium diklofenak (Na-diklofenak) adalah obat anti inflamasi non steroid yang umumnya digunakan untuk penderita radang sendi. Namun, waktu paruh yang pendek sekitar 1-2 jam menyebabkan obat diberikan berulang kali dalam interval waktu yang pendek untuk pemberian secara oral. Oleh karena itu, tujuan penelitian ini yaitu memformulasi Na-diklofenak tablet sustained release menggunakan metolose 90 SH 4000 sebagai matriks. Untuk melihat pengaruh metolose 90 SH 4000 terhadap profil disolusi Na-diklofenak tablet sustained release, metolose 90 SH 4000 ditambahkan dengan perbandingan 0% (F0), 5% (F1), 10% (F2), 15% (F3), 25% (F4). Tablet Na-diklofenak dibuat dengan metode granulasi basah. Hasil disolusi menunjukkan formula F0, F1, F2 dan F3 dapat dicapai dalam waktu 120, 240, 300 dan 480 menit, berturut-turut, namun F4 tidak mencapai disolusi selama 480 menit. Bedasarkan USP 26, hanya F3 yang memenuhi syarat disolusi tablet sustained release.Diclofenac sodium (Na-diclofenac) is a non-steroidal anti-inflammatory drug that is commonly used for arthritis patients. However, its short half-life time which is about 1-2 hours causes the drug should be administered repeatedly over a short time interval for oral administration. Therefore, the purpose of this study was to formulate a sustained release tablet of diclofenac sodium with metolose 90 SH 4000 as the matrix. In order to see the influence metolose 90 SH 4000 to the dissolution profile of diclofenac sodium tablet, metolose 90 SH 4000 was added with a ratio of 0% (F0), 5% (F1), 10% (F2), 15% (F3), 25% (F4). The tablets was prepared by wet granulation method. The dissolution results showed the formula F0, F1, F2, and F3 can be reached within 120, 240, 300, and 480 minutes, respectively. Meanwhile, F4 did not reach the dissolution for 480 minutes. According to the USP 26, only F3 qualified the dissolution of sustained release tablet
