What to Look for in Statistical Software


By Mark J. Anderson, Principal, Stat-Ease, Inc.

Statistical methods are becoming increasingly important for the pharmaceutical industry. The FDA and other regulatory and standard-setting organizations are moving swiftly to establish Quality by Design (QbD) guidance relevant to the needs of pharmaceutical manufacturing. The FDA suggests the use of design of experiments (DoE) because “it provides a structured, organized method for determining the relationship between factors affecting a process and the response of that process.”

Optimizing Design of Experiments for Fluid Bed Coating


Upsher-Smith Laboratories (Minneapolis, Minn.) faced a problem with a fluid bed coating process that produced inconsistent results. Many of the coating parameters interacted with each other, so conventional one-factor-at-a-time (OFAT) experiments were unable to resolve the issue. Sarah Betterman, scientist for Upsher-Smith, used design of experiments (DoE) to determine how the key coating process parameters affect dissolution, the critical response.
