Parenteral administration is the introduction of a nutrient, drug or other substance into the body rather than through the digestive tract. Unlike oral or rectal administration, the introduction of drugs into the body via parenteral administration poses greater risks. Parenteral suspensions are dispersed, heterogeneous systems containing insoluble drug particles and are dosage forms containing low solubility drugs. The suspension form improves the solubility and stability of the drug, and the sulfonated form has a larger surface area. Parenteral suspensions have a longer onset of action compared to solutions. Most parenteral suspensions are designed for intramuscular or subcutaneous administration.
Parenteral suspensions of poorly water-soluble salts for intramuscular injection maintain therapeutic drug concentrations over a long period of time. In vitro drug dissolution tests are a prerequisite for assessing batch-to-batch differences and for ensuring drug release during formulation development. CD Formulation offers specific services including the following:
Performance testing of suspensions.
Data reporting and analysis.
