Fast Compatibility Check by Means of DSC and SuperPosition

by

Drug-excipient compatibility studies constitute an important phase in the development stage (pre-formulation) of dosage forms. They provide information whether physicochemical interactions happen between API (active pharmaceutical ingredient) and excipients. Differential scanning calorimetry (DSC) and thermogravimetry (TGA) are fast and easy-to-use methods to get first information about drug-excipient compatibility. For that, DSC and/or TGA measurements are … Read more

Drug-Excipient Compatibility Check

by

Drug-excipient compatibility studies are an important part during the development of a new formulation. They ensure that no interaction occurs between drug and excipients that could affect the properties, stability, efficacy of the active ingredient. Thermal Analysis is used for rapid assessment of physicochemical interactions.

The Phenomenon Polymorphism – A Major Impact on Drug Performance

by

The term polymorphism comes from the Greek, “poly” meaning “multiple” and “morph” meaning “form”. Used in different areas as programming or biology, it designates the ability of a variable, of an object, of a gene to take on multiple forms. In the pharmaceutical industry, polymorphism refers to the ability of a material to exist in … Read more

Compatibility of Drug and Excipient: Faster and Easier By Means of Thermal Analysis and SuperPosition

by
DSC in Pharma R&D

Compatibility refers to harmony in a relationship, but is also an important term in science, be it in medicine where only a compatible organ can be transplanted to a recipient, or in computing to refer to software packages that can be used together. This concept is also well-known in the pharmaceutical field: Two components (e.g., … Read more
