Hold Time Validation: purpose and scope
Hold-time studies support justified manufacturing holding periods. The WHO reference below primarily addresses non-sterile solid dosage forms; it excludes API and biological manufacture and cleaning-validation hold times.
Holding conditions
Define containers and environmental conditions.
Sampling plan
Specify sampling intervals and quantities.
Tests and acceptance criteria
Select relevant quality tests and justified limits.
Results and conclusions
Evaluate observations, trends and deviations.
Review after changes
Assess whether changes require further studies.

For QA, QC, production and validation teams.
Hold time validation protocol
Check the proposed conditions, sampling and limits.
Hold time validation report

Common questions
How do protocols and reports differ?
Protocols plan the study; reports document results and conclusions.
Is there one hold time for every product?
Holding periods need evidence for the specified product and conditions.
Does a template validate a hold time?
An approved study and its evaluated results provide the supporting evidence.
