Aggregation or coagulation of drug particles in a parenteral suspension can pose a serious threat to product quality, particularly for products that require extended shelf life. In the worst case, aggregation can lead to the formation of a nonresuspendable sediment, known as caking. Controlling physical stability is difficult because of the complexity of this phenomenon. This article gives an overview of the factors that were found to be the most important in our search to improve the physical stability of a pharmaceutical suspension.
