Simultaneous adsorption of chlordimeform and zinc on montmorillonite
The competitive adsorption of the cationic pesticide chlordimeform and the heavy metal zinc on montmorillonite was studied. For different concentrations of Zn used, chlordimeform decreases (in relation to Zn-free treatments) when the pesticide is adsorbed simultaneously with the metal, but increases when Zn is adsorbed previously to chlordimeform. When comparing the Ko values chlordimeform is s...
متن کاملSolid Sirolimus Self-microemulsifying Drug Delivery System: Development and Evaluation of Tablets with Sustained Release Property
The clinical application of sirolimus (SRL) as an immunosuppressive agent is largely hampered by its narrow therapeutic range. This study focused on developing SRL tablets with a sustained release profile for better safety. SRL was highly water insoluble and its solubility has been efficiently enhanced by preparing self-microemulsifying drug delivery system (SMEDDS). The SRL-SMEDDS was physical...

متن کاملPreparation of Sustained-Release Matrix Tablets of Aspirin with Ethylcellulose, Eudragit RS100 and Eudragit S100 and Studying the Release Profiles and their Sensitivity to Tablet Hardness
A sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. In this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (EC), Eudragit RS100 (RS), and Eudragit S100 (S) were prepared by direct compression. The release behaviors were then studied in two co...
