Basics: Excipients Used in Nonsterile Compounding, Part 1

Area of Science:

• Pharmaceutical Sciences
• Drug Delivery
• Formulation Development

Background:

• Pure drug substances are rarely administered directly due to various limitations.
• Formulation into dosage forms is essential for efficacy, safety, stability, and patient compliance.
• Dosage forms contain active drug substances alongside pharmaceutical ingredients, known as excipients.

Purpose of the Study:

• To introduce the concept and necessity of pharmaceutical excipients in drug formulation.
• To provide an overview of the categorization of excipients based on their functions.
• To set the stage for detailed discussions on specific excipient characteristics and applications in future publications.

Main Methods:

• Review of fundamental principles in pharmaceutical formulation.
• Classification of pharmaceutical excipients based on their roles in dosage forms.
• Identification of key considerations in drug substance formulation.

Main Results:

• Drug substances necessitate formulation into dosage forms for practical administration.
• Pharmaceutical excipients are crucial components of these formulations, varying widely in type and function.
• Excipients are typically categorized based on their intended use within a dosage form.

Conclusions:

• Understanding excipient categories is vital for effective pharmaceutical formulation.
• The complexity of excipients requires systematic study for optimal drug product development.
• This overview serves as a foundation for in-depth analysis of excipients in subsequent publications.
