Mottling- unequal colour distribution of a tablet.
Capping- Partial or complete separation of a tablet top or bottom crowns.
Lamination- Separation of tablets into two or more layers.
picking- Because of adhesion to the punch faces, Localized portion missing on the surface of the tablet.
Sticking- Adhesion of tablet localized portion to the punch faces resulting in rough and dull appearance.
It is the time required for the Tablet / Capsule to break into particles, the disintegration test is a measure of the time required under a given set of conditions (Temperature) for a group of tablets/capsules to disintegrate into particles.
Cycle of shaft holding the tube basket limit is 29-32 cycles per minutes and distance covered by shaft basket is 50-60 mm and beaker temperature is 35 to 39 º C.

Friability is defined as the percentage of weight loss of powder from the surface of the tablets due to mechanical action and the test is performed to measure the weight loss during transportation.
Friability (%) =W1– W2/W1X100
Where,
W1 = Weight of Tablets (Initial / Before Tumbling) &
W2 = Weight of Tablets (After Tumbling or friability)
Limit : Friability (%) = Not More Than 1.0 %
Tablets with individual weight equal to or less than 650 mg then take the sample of whole corresponding to as near as 6.5 gram equivalent and tablets with individual weight more than 650 mg then take sample of 10 whole tablets to perform friability test. Tablets must be de-dusted prior to and after use.
The action of proving that any equipment or process work correctly and consistently and produces the expected result. Qualification is part of, but not limited to a validation process, i.e. Installation Qualification (IQ), Operation Qualification(OQ) and Performance Qualification (PQ).
The act of planning, carrying out and recording the results of tests on equipment to confirm its capabilities and to demonstrate that it will perform consistently as intended use and against predefined specification.
A requirement specification that describes what the equipment or the system is supposed to do, thus containing at least a set of criteria or condition that have to meet.
Detailed design & functional specifications shall be taken from the supplier for a particular piece of equipment / instrument / system / facility. The same shall be prepared by User & reviewed by Engineering & Quality Assurance. Based on the specifications, URS document shall be prepared
Consecutive meaning following closely with no gap or following one after another without interruption.
The number of batches to be taken under validation depends upon the risk involved in the manufacturing Critical process parameters & critical Quality Attribute so depends upon that manufacturer have to choose the number of batches to be validated.
If we will consider less than two batches then the data will not be sufficient for evaluation of and to prove reproducibility of data between batch to batch variation & if we consider more than three batches it can increase the time & cost of manufacturer which usually not preferred.
Generally if we will require quality in the First batch, then it is accidental (co-incidental), Second batch quality is regular & third batch quality is Validation or Confirmation.
Statistical evaluation cannot be done by considering two points, because two points always draw a straight line so minimum three points required for comparison of data.
Part I is GMP for Factory Premises and Part II is GMP for Plant & equipment’s.
Any unwanted event that represents a departure from approved processes or procedures or instruction or specification or established standard or from what is required. Deviations can occur during manufacturing, packing, sampling and testing of drug products.
Examples of Deviations: Temperature and RH of area goes out of limit during manufacturing, Typographical error observed in approved documents, Standard operating procedure not followed, Breakdown of equipment, Spillage of material during unloading, Instrument calibration results goes out of limit etc. Deviations are of three types Minor, Major and Critical
It is a Approved Procedure which is taken to change in any documents, Standard operating procedures, Specification, Process parameters and change in batch size etc. Change control is raised by user department as per requirement and finally the change control is approved by Quality assurance. Change control can be raised through software or through manually.
After Final approval of change control the changes can be made in documents and change control can be closed after completion of required action plan which is mentioned in the Change control form.
Change controls are of two types i.e Major and Minor.
A Site Master File (SMF) is a document that describes the structure of the organization which includes the site, the manufacturing activities carried out, the facility and premises, number of employee with their Qualification, Production system, Quality Control System and also details of the quality management system which are in place.
It contains General information about the plant, Quality System, Personnel, Premises and Equipments, Production system, Documentation, Quality Control system, Self Inspection and site inspection history etc.
A Validation Master Plan is a document that summarizes the firm’s/organizations overall philosophy, intentions and approach to be used for establishing performance adequacy. It provides information on the firms/organizations validation work programme and defines details of and timescales for the validation work to be performed, including a statement of the responsibilities of those implementing the plan.
It contains the validation policy, Process & Cleaning validation, Qualification & Requalification, Computer validation, Utility validation & Qualification, Vendor Qualification , Temperature mapping, Change control, Deviation, Risk Assessment, Standard Operating procedure, Training, Area Qualification, calibration and Preventive maintenance & closure of VMP etc. VMP Shall be updated yearly.
An appropriately identified sample that is representative of each batch that shall be retained is known as control sample. These are also referred as retention or reference sample.
The control sample shall be collected at the initial, middle and at the end of packing operation of the batch and the details of the total pooled quantity collected shall be entered in the respective Batch Packing Records with sign, date & sample collection time.
The control sample should consist of twice the quantity required for complete analysis and Sample quantity shall be decided on the basis of specifications given by Quality Control.
Control sample shall be collected for Raw material, Packing Material and Finished Products
It is a documented evidence which provides us the assurance that a cleaning procedure is consistently removing product residue from equipment.
Three batches shall be taken for Cleaning validation After the Cleaning procedure for the equipment’s are validated, periodic monitoring / Cleaning verification shall be done once in year on worst case product
The product selected from a group of products that represents a greater risk of carry over the residue of previous product to next product manufactured using the same equipment by virtue of its solubility, Cleanability, Permitted daily dosage exposure, toxicity or a combination of these factors, therapeutic dose, etc.
It is the case or condition where there is a chances of Product failure.
Line clearance is a process which provides a high degree of confidence or assurance that the said line or area is free from any unwanted residue or left over of previous processing’s before proceeding for next process. Quality assurance has to provide Line clearance before the start of any activity whether it is batch to batch change over and Product to product change over.
Line clearance shall be given by Quality Assurance at Raw material Dispensing stage, Manufacturing stage, Packing stage and in Quality Control before start of any activity.
Water system validation has been categorized into 3 phases: Phase I, Phase II and Phase III.
Phase I Requires a 2 – 4 weeks (14 days minimum) testing period in order to monitor the system deeply.
Phase II is continuity of previous phase i-e phase I, it carries the sampling plan same as previous phase plan & it also facilitates the monitoring of system for 2 – 4 weeks (30 days) period.
In phase III sampling locations and frequency reduced as compared to previous phases. Phase III represents that the water system shows reliable under control attainment over such a long time period & Phase III typically runs for one year after the satisfactory completion of phase II.
A product recall is a request from a manufacturer to return or removal of a marketed product after the discovery of safety issues or product defects that might endanger the consumer or put the maker/seller/ manufacturer at risk of legal action.
Mock means Make a Duplicate or exact copy of something.
Mock recalls are routine exercises conducted by manufacturers, processors, distributors and other various trading partners in the supply chain to assess or verify their recall procedures and responsiveness and to train the recall team.
