Solution Overview

Problem

Daprodustat tablets require enhanced mechanical strength to withstand handling and storage without crumbling, while maintaining suitable disintegration for oral administration, as existing formulations struggle with tensile strength and friability.

Innovation Solution

An immediate release tablet formulation of daprodustat with a tablet tensile strength of at least 1.7 MPa, achieved by compaction pressures between 200 to 290 MPa, and optimized using a non-solvated crystalline form of daprodustat without glidants in the compartment, ensuring robustness and effective disintegration within 45 minutes.
