Procedure:-
The
following statistical techniques / tools are being used in the plant.
A) Sampling Plan for Incoming Materials & Product
For the sampling of incoming goods and produced batches American military standard MIL-STD 105 – E is being used to take the representative samples for inspection / testing of raw materials, packaging components and finished products. Acceptance levels are defined on the basis of these plans and reports are generated for each sample and analysis.
In process
Inspection Data
Physical parameters of liquid injections, Liquid
syrup, Tablets, Capsules and dry powder injections are checked during the
operation at predefined frequencies. Results are plotted on pre-printed trend
charts (range charts) are provided with upper and lower allowable limits.
Trends are
reviewed regularly during the process by production and IPC staff and are
finally reviewed by QC Department before final release.
Finished
Products (Active Potency data analysis by Line Graph)
Results of
active ingredient’s assay are plotted for each batch on graph sheet to analyze
the trend of batch wise product quality.
These plotting are reviewed in GMP committee and quality
council meetings. The observations are discussed & appropriate corrective
and preventive actions are identified for improvement.
This
statistical technique is applied for the data analysis in
a)
Liquid Injectable Volume data in QC Lab.
b)
Powder Injectable drug weight data in QC Lab
c)
Weight Variation data of OSD (Tablets & Capsules)
forms in QC Lab.
d)
Liquid Syrup Volume data in QC Lab
e)
Analytical method validation in QC Lab.
f)
Process Validation in Production
Standard deviations calculated to
establish consistency of the relevant process / method.
