Rate-dependent mechanical properties of dry blended pharmaceutical powder formulations for tabletting applications

► Mechanical properties of pharmaceutical powder formulations were determined. ► These properties such as bulk modulus and compression index increased with pressure. ► At 10 MPa/min, bulk modulus increased with the binder content. ► At 10 MPa/min, spring-back and compression index decrease with the binder content. ► The powder formulations were rate-dependent.
