Excipients are materials added along with therapeutic agents; and incompatibility between excipients and therapeutic agents affect the final outcome of the product. Aspirin is an ester and is prone to hydrolysis. This study focus on the effect of magnesium stearate as an excipient on stability of aspirin in granules. For that an accelerated degradation study was done on aspirin-magnesium stearate containing granules. For that, aspirin containing granules were sequentially mixed with increasing...

Water-soluble polymers with high viscosity are frequently used in the design of sustained-release formulations of poorly water-soluble drugs to enable complete release of the drug in the gastrointestinal tract. Tablets containing matrix granules with a water-soluble polymer are preferred because tablets are easier to handle and the multiple drug-release units of the matrix granules decreases the influences of the physiological environment on the drug.

As an essential formulation component for large-scale tablet manufacturing, the lubricant preserves tooling by reducing die-wall friction. Unfortunately, lubrication also often results in adverse effects on tablet characteristics, such as prolonged disintegration, slowed dissolution, and reduced mechanical strength. Therefore, the choice of lubricant and its optimal concentration in a tablet formulation is a critical decision in tablet formulation development to attain low die-wall friction...
