ANALISIS SUKRALFAT PASCAKALSINASI UNTUK OBAT SITOPROTEKSI PADAMUKOSA LAMBUNG. Telah dilakukan sintesis dan karakterisasi bahan sukralfat untuk obat sitoproteksi pada mukosa lambung. Sukralfat merupakan garam aluminium dari sukrosa sulfat. Pada suasana perut kosong, obat ini membentuk pasta kental yang secara selektif mengikat ulkus/luka yang stabil antara molekul obat dengan protein pada permukaan ulkus. Sukralfat dikalsinasi pada suhu 100°C, 300°C dan 500°C. Tujuan yang ingin
dicapai pada penelitian ini adalah mengetahui dan memahami pengaruh suhu kalsinasi terhadap kemampuan sukralfat dalam menetralisasi dan mempertahankan pH lambung, juga dapat meningkatkan kualitas mukoadhesif dari sukralfat tersebut. Karakterisasi sampel meliputi analisis fasa dan derajat kristalinitas, uji kemampuan menetralkan asam, uji kemampuan mempertahankan pH lambung, dan uji mukoadhesif. Disimpulkan bahwa bahan sukralfat yang memiliki kemampuan menetralisasi dan mempertahankan pH lambung tertinggi serta mempunyai kualitas mokoadhesif yang baik adalah sukralfat yang dikalsinasi pada suhu 100°C dengan karakteristik mengandung fasa Bayerite dan fasa diaspore, derajat kristalinitas sebesar 65,46%, memiliki kemampuan menetralkan asam sebesar 17,44786 (nilai UPH XVII), mampu mempertahankan pH ≥ 3 selama 33 menit, dan memiliki kualitas mukoadhesif yang baik. Sehingga diharapkan dapat lebih efektif digunakan sebagai obat sitoproteksi pada mukosa lambung.
ABSTRACT
ANALISYS OF SUCRALFATE MATERIAL FOR THE DRUG OF GASTRIC MUCOSAL CYTOPROTECTION. The synthesis and characterization of sucralfate material for the drug of gastric mucosal cytoprotection has been performed. The sucralfate is an aluminum salt of sucrose sulfate. In the atmosphere of an empty stomach, the drug will form a thick paste selectively. And bind to the ulcer/wound stablily between the drug molecules to proteins on the surface of the ulcer. The sucralfate calcined at 100°C, 300°C, and 500 °C. The purpose of this study was know and understand the influence of calcination temperature on the ability to neutralize and Sucralfate in maintaining gastric pH, may also improve the quality of Sucralfate is mucoadhesive. The characterization of samples included analysis phase and the degree of crystallinity, acid
neutralizing capacity test, test of the ability to maintain gastric pH, and test mucoadhesive. We concluded that the sucralfate material that has the ability to neutralize gastric pH and maintain the highest quality and have a good mokoadhesif is the sucralfate is calcined at a temperature of 100°C with the characteristics of the phase contain Bayerite and diaspore phase, the degree of crystallinity of 65.46%, has the ability to neutralize the acid at 17, 44786 (UPH value XVII), capable of maintaining pH ≥ 3 for 33 minutes, and have a good mucoadhesive quality. Thus, the sucralfate was expected to be more effectively used as a drug of gastric mucosal cytoprotection.
