Application

Design takeaway

How to apply

When developing new topical formulations, begin by defining the CQAs, then use DoE to understand how formulation and process variables impact these CQAs, and finally, establish control strategies to maintain quality throughout manufacturing.

Project actions

01When designing a product, think about what makes it 'work well' (CQAs) and how to control those things.
02Use experiments (like DoE) to test different ideas and find the best way to make your product.

Method & Evidence

AimTo systematically review the application of Quality by Design (QbD) principles in the development of topical semisolid formulations, focusing on Critical Quality Attributes (CQAs), Design of Experiments (DoE), and control strategies.

MethodSystematic Review

ProcedureA systematic search of PubMed and Google Scholar was conducted using predefined Boolean queries to identify studies reporting the application of QbD to topical semisolids, detailing CQAs, DoE, and control strategies.

ContextPharmaceutical product development, specifically topical semisolid formulations (creams, ointments, gels).

Variables

IVApplication of QbD principles (CQAs, DoE, control strategies)

DVBioequivalence, product quality, scalability, regulatory compliance

CVType of topical formulation (creams, ointments, gels), specific drug being delivered, manufacturing scale.

Strengths & Limitations

Strengths

+Comprehensive review of a critical development methodology.
+Focus on a specific, complex product type (topical semisolids).

Limitations

The complexity of QbD can be challenging to fully implement in a limited design project scope. The availability of advanced statistical software for DoE might be a constraint.

Reliability & validity

The reliability of the review depends on the quality and consistency of the studies included. Validity is enhanced by adhering to PRISMA guidelines for systematic reviews.

Think critically

How might the principles of QbD be adapted for non-pharmaceutical products where 'bioequivalence' is not a direct concern, but product consistency and performance are critical?

Design Principles

"Proactively define and control critical quality attributes throughout the product development lifecycle using systematic experimental design and robust control strategies."

For designers and engineers developing pharmaceutical products, QbD offers a proactive approach to ensure product quality and regulatory compliance. By understanding and controlling critical parameters early in the design process, it mitigates risks associated with complex formulations like creams and ointments, leading to more reliable and effective treatments.

What This Means for Your Design

Using a structured approach called Quality by Design (QbD) helps make sure that creams and ointments for skin work consistently and are the same every time they are made.
