A novel lipid-containing co-processed excipient significantly improves acetaminophen powder flowability and tablet mechanical properties. This excipient demonstrates superior performance over RetaLac® in overcoming API processing challenges.
Area of Science:
- Pharmaceutical Technology
- Materials Science
Background:
- Direct compression for tablet manufacturing is limited by poor active pharmaceutical ingredient (API) flowability and compaction.
- Co-processed excipients offer a solution to enhance API processability.
Purpose of the Study:
- To evaluate a novel lipid-containing co-processed excipient for improving acetaminophen (API) properties.
- To compare the novel excipient's performance against a commercial co-processed excipient, RetaLac®.
Main Methods:
- Flowability tests and comprehensive tableting property evaluation.
- Utilized USP-recommended compression characterization and dynamic compaction analysis.
- Assessed tablet tensile strength, compression, detachment, and ejection stresses.
Main Results:
- The novel excipient exhibited superior flowability with acetaminophen compared to RetaLac®.
- Acceptable tablet tensile strength (>1 MPa) was achieved with 30% acetaminophen using the novel excipient.
- The novel excipient showed a significantly higher ability to overcome API adhesiveness, indicated by lower compression, detachment, and ejection stresses.
Conclusions:
- The novel lipid-containing co-processed excipient effectively enhances the tableting properties of acetaminophen.
- This excipient presents a promising alternative for overcoming processing challenges associated with cohesive and viscoelastic APIs.
- Compression speed and dwell time are critical factors for achieving optimal tablet mechanical properties with viscoelastic APIs.
