6 Steps to Ensure Robust Design & Performance of Hydrophilic Matrices

November 14, 2019

Quality by Design (QbD) is a systematic approach to pharmaceutical development. It means designing and developing formulations and manufacturing processes to ensure predefined product quality.1 In the case of hydrophilic matrix tablets, using hypromellose as the rate-controlling polymer, it is critical to consider the variability in properties of the polymer2 in addition to the variabilities in API properties and processing conditions.

Keep the following 6 steps in mind when implementing a QbD strategy to ensure the robust design and performance of your hydrophilic matrices.

1. Consider material attributes (MA)

Variations in viscosity, particle size and hydroxypropyl substitution levels (% HP) of the rate-controlling polymer can impact drug release performance of the matrix formulation. Ensure proactive risk assessment of these MAs to ensure robust matrix formulation design and performance.

2. Optimize formulation design

Lower formulation risk and improve productivity in the development phase, with a first-time-right approach. By optimizing the formulation in early design phases, manufacturers can avoid costly mistakes in downstream processes.

3. Tap into prior knowledge and expertise

Consult us for case studies, technical knowledge, and recommendations. Leveraging outside resources for formulation and polymer expertise will undoubtedly speed up development processes.

4. Implement a manufacturing control strategy

Manage drug product risk using process trend data to generate a manufacturing control strategy.  Limited manufacturing variability of hydrophilic matrix systems will lead to less product rejection and reduced waste.

5. Mitigate regulatory risks

Manage regulatory burden, minimize recalls and compliance actions. Meet first cycle regulatory requirements and reduce supplemental submissions, increasing speed to market.

6. Secure your supply chain

Suppliers should have a thorough business continuity plan and ideally multiple manufacturing sites to deliver security of supply, reduce operational risk, and provide consistent quality and availability of key materials globally.
