Abstract

Rosuvastatin calcium is a salt form of rosuvastatin with antilipidemia activity. Rosuvastatin Calcium classified in class two of Biopharmaceutics Clasification System (BCS) has low solubility in water (17.96 mg / L) and high permeability. Based on this, rosuvastatin calcium needs to be formulated appropriately in order to produce high bioavailability and maximum therapeutic effect. The bioavailability of BCS 2 drug is determined by the dissolution rate of the drug in gastrointestinal fluid so that a technique is needed in formulating the drug. This study aims to develop a formulation technique for rosuvastatin calcium tablets through liquisolid technique and formation of inclusion complexes with β-cyclodextrin in order to increase the rate of dissolution. Tablet formulation with liquisolid technique was made with a concentration of 10% rosuvastatin calcium in propylene glycol, with a ratio of US2® (carrier) and Aerosil 200 (coating) made with a ratio of 10: 1 and 20: 1. In addition to the formulation with liquisolid technique, formulations were also carried out with the complex inclusion technique of rosuvastatin calcium-β-cyclodextrin using kneading method and freeze drying method with a mol ratio of 1: 1 and 1: 2. The liquisolid system and inclusion complexes formed were characterized using FTIR and SEM. Characterization results indicated changes in the form of polymorphous rosuvastatin calcium. Tablet formulations were made by direct compression using a liquisolid system and an inclusion complex equivalent to 10 mg of rosuvastatin calcium. Based on the results of the ANOVA statistical test and further LSD tests showed that calcium rosuvastatin tablets made with liquisolid and inclusion complexes can increase the dissolution rate compared to pure rosuvastatin calcium tablets and inovator rosuvastatin calcium tablets. The highest dissolution rate was produced by liquisolid R20: 1 tablet at 60 minutes at 85.53 ± 1.02% in an enzyme-free simulated gastric fluid dissolution medium and 110.02 ± 1.71% in an enzyme-free simulated intestinal fluid dissolution medium.

Abstract

Kurkumin merupakan senyawa aktif yang memiliki berbagai manfaat farmakologis, namun keterbatasan kelarutannya dalam air menjadi pertimbangan dalam pengembangan sediaan, salah satunya dengan menggunakan basis effervescent. Penelitian ini bertujuan untuk mengevaluasi potensi inkompatibilitas antara kurkumin dan beberapa eksipien effervescent, yaitu asam sitrat, asam tartrat, dan natrium bikarbonat. Metode penelitian meliputi uji homogenitas, organoleptik, mikroskopik, kadar air (LOD), kristalinitas, dan sifat termal. Campuran dibuat dengan perbandingan 1:1 menggunakan mixer selama 10 menit dengan kecepatan 60 rpm. Hasil menunjukkan adanya variasi dalam homogenitas, perubahan fisik, kadar air, dan karakteristik termal pada masing-masing campuran. Secara umum, campuran kurkumin dengan asam tartrat dan natrium bikarbonat menunjukkan kestabilan yang relatif baik dibandingkan dengan campuran yang mengandung asam sitrat, yang menunjukkan beberapa perubahan selama penyimpanan. Kesimpulan penelitian menunjukkan bahwa asam tartrat merupakan basis effervescent yang paling kompatibel untuk formulasi sediaan kurkumin, sedangkan asam sitrat menunjukkan potensi inkompatibilitas.
