Abstract:
Obtaining an elegant finished pharmaceutical product remains a problem when salt concentration is high, protein concentration is low, and particularly when both conditions are combined. We propose a simple approach to develop a robust lyophilized formulation in the presence of salt and at low protein concentration. We combine this with a commercially viable lyophilization cycle that can serve as a starting point for many protein-based pharmaceutical products. In this manner the formulator scientist, even with little experience, can develop a robust and visually acceptable lyophilized product. In addition, this platform allows the production of placebo vials with no visual differences compared to the active product.

Some polymorphic crystals possess lower aqueous solubility than their amorphous counterparts, leading to incomplete absorption. For instance, the oral suspension of Chloramphenicol, which...
