What Is Line Clearance?
Line clearance is the activity or process which ensures that the area, line, or equipment is free from residues, and labels of previous products and is ready for dispensing,manufacturing,printing or packaging activity.
What We Check During Line Clearance?
During line clearance, QA officers check that all the area and equipment are properly cleaned/washed and there is no leftover of the previous product.
The following main points are checked,
- Area/equipment Identification
- Calibration Record
- Temperature
- Humidity
- Differential Pressure
- Log Books Record

What Is Documentation?
All types of written material used in pharmaceutical industries including procedures, SOPs, work instructions, etc are known as documentation.
What Is Good Documentation Practice GDP?
Good documentation practice or GDP is the collection of standards or internationally accepted guidelines that are used for creating documents & record keeping and it helps for data integrity.
What Is ALCOA?
ALCOA is used for good documentation practices and stands for,
- Attributable
- Legible
- Contemporaneous
- Original
- Accurate
What Is SOP?
SOP is the standard operating procedure and it is written instruction about how a task or activity will be performed.
Read Details
What Is SCP?
SCP is a standard cleaning procedure & is a written document that contains all the instructions regarding the cleaning procedure of equipment, utility, or facility.
What are The Types Of Cleaning?
There are 3 types of cleaning in the pharmaceutical industry which are given as below
- Major Cleaning
- Minor Cleaning
- Shift End Cleaning
What Is Change Control?
Change control is a documented system in pharmaceutical industries to control & regulate any changes in the existing system.
Is Change Control Required For New Area Or Equipment?
Most people in the pharmaceutical industry think that change control is only generated when we change any old procedure or equipment but the reality is that it is also generated whenever we want to add any new equipment or facility.
Types Of Changes
Changes May be of two types
- Planned Changes
- Unplanned Changes
What Are Inprocess Checks?
In-process checks are the tests/activities which are performed during the period when a specific activity i.e manufacturing, filling, printing,labeling or packaging is running and is not finished.
These checks are performed to ensure that all the required standards are met during a specific operation.
Examples Of Inprocess Checks?
Following are some examples of in-process checking for various operations.
For Granulation
LOD
Granule size
For Compression
Hardness
Weight Variation
For Coating
Weight Gain
Color uniformity
For Filling
Volume Checking
Clarity Checking
For Printing
Embossing Pattern
For Blistering
Sealing

- Reciprocating Disc
Which Equipment Is Used For Disintegration Tests?
The equipment which is used for checking Disintegration time is known as Basket Rack Assembly.
How Many Tablets Are Used For Disintegration Tests?
First, we take 6 tablets for the disintegration test & if one or two tablets fail to disintegrate we repeat the test with 12 more tablets. The test is considered pass if 16 out of 18 tablets disintegrate in a specified time.
Define Friability?
Percentage weight loss is known as friability.
Which Equipment Is Used For Friability Tests?
Roche friabilator is used for checking the friability of tablets.
For Which Types Of Tablets Do We Perform Friability Tests?
Friability test is performed for core or uncoated tablets.
It is not performed for coated tablets because polymers in coting formulations give strength to the tablets.
At Which Height Tablets Fall during Friability Test?
Tablets fall at a height of 6 inches during the friability test.
What Is The Acceptance Criteria for Friability Test?
Not more than 1%
What Is The Formula To Calculate Tablet Friability?
Tablet friability is calculated by using the following formula,
Initial Weight(W1) – Final Weight(W2)÷ Initial Weight(W1) × 100
