Raw material identification or incoming goods inspection is of paramount importance for the quality and safety of drug products, wherever chemical substances are used in the pharmaceutical industry – maybe as an educt of chemical reactions or as a basis for further processing.
Differential Scanning Calorimetry (DSC) offers a quick and easy way to determine the purity of crystalline substances. Only one measurement with a few milligrams of sample is needed. Read here how it works!
The increasing number of product recalls in recent months has again made us aware how important the purity of drug ingredients is. Differential scanning calorimetry (DSC) is able to quickly analyze the absolute purity of chemical compounds within a single run, without the need for a reference standard.
Paracetamol (acetaminophen) is the most commonly used medication for pain and fever in both the United States and Europe. However, it is not worth getting a headache when you think about its physicochemical properties. Thermal analysis, and especially differential scanning calorimetry (DSC), is of great help.
From the chemical point of view, diamonds are just made of carbon. The phenomenon that chemical elements can occur in different forms within the same phase, i.e., in different structural modifications, is called allotropy. Due to the relationship between crystal modification and melting point, Differential Scanning Calorimetry (DSC) is ideally suited to discriminate between different polymorphic forms. A more general term for chemical compounds is polymorphism.
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.
How does temperature and humidity influence the quality, stability and efficacy of pharmaceuticals? Thermal Analysis provides first information.
The thermal stability of a substance is closely related to the shelf-life of pharmaceutical products. Here, the thermal stability of diclofenac sodium (anti-inflammatory) is determined by means of thermogravimetry.
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 moreThe Phenomenon Polymorphism – A Major Impact on Drug Performance
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 moreCompatibility of Drug and Excipient: Faster and Easier By Means of Thermal Analysis and SuperPosition
