What is the Origin of Novel Excipients?

The designation 'Novel' signifies that the excipient is new to the regulatory landscape or has a new proposed application, while 'Excipient' denotes the inactive carrier substance. This terminology is critical in regulatory science, distinguishing these materials from the well-characterized, older cohort of inactive ingredients.

What is the Mechanism of Novel Excipients?

Novel excipients operate by interacting with the active drug molecule or the biological environment in ways conventional excipients cannot, perhaps by forming inclusion complexes to protect sensitive biologics like certain peptide hormones from degradation. Their mechanism of action centers on improving the physicochemical properties of the final dosage form to achieve superior bioavailability or controlled release kinetics. Rigorous toxicological assessment is required to ensure these new materials do not induce unforeseen adverse physiological responses or endocrine disruption.

Novel Excipients

Meaning

Novel Excipients are substances introduced into pharmaceutical formulations that have not been previously approved or widely utilized in marketed drug products, requiring extensive qualification studies before clinical use, particularly for sensitive delivery systems like peptide hormone injections. These new components are often designed to enhance solubility, improve stability, or facilitate targeted delivery of the active therapeutic agent. Their introduction pushes the boundaries of drug formulation science.
