The stabilizers are added in the formulation to prevent this. To make the formulation isotonic. When these are formulafion as vehicles,then formulations should not be diluted with water as precipitation may occur. The stability of the drug substance is another critical point that a formulator can face during the development of the formulation.

Sunday, November 20, Chelating agents are compounds that can form complexes with metal ions, and in so doing inactivate the catalytic activity of the metal ions in the oxidation process. Parenteral preparations are sterile and pyrogen-free formulaation intended to be administered directly into the systemic circulation in human or animal body.

With regards to solutions and emulsions, the drug substances should be soluble and parentefals soluble during the entire shelf-life of the drug products.
