This SOP is applicable for the Production Area of  XX Pharmaceuticals Limited.

Definitions / Abbreviation:

[][]N/A.

Responsibilities:

[][]The Roles and Responsibilities are as follows:

Operator

[][]To follow the laid down procedure

Executive, Production

[][]To monitor and check the cleanliness of area

Manager, Production

[][]To implement this correctly

Manager, Quality Assurance

[][]To approve the Document

Procedure:

Precaution :

[][]Do not clean/disinfect the area when the process is running.
[][]Keep the cleaning agents at the designated place only with proper labels.
[][]Ensure that after usage the wet mops are washed and hanged in hanger in cleaner store &allowed to dry. Ensure other cleaning tools are also hanged in hanger after use.
[][]After use of cleaning agent wash hands, feet and fingers thoroughly with soap & plenty of water.
[][]Ensure that during cleaning all the product containers are closed.
[][]Check and ensure that disinfectant solution prepared is not stored for use for the next day and the residue is discarded by pouring into drain.
[][]At least two different disinfectants are to be used alternatively on weekly basis.
[][]Do not mop the floor after keeping ‘Cleaned’ equipment in clean equipment storage room.

Cleaning Tools / Agents

[][]Portable vacuum cleaner
[][]Cloth & wiper
[][]Potable water and Purified water
[][]Glass Cleaning agent: ‘Clear View’ (Brand Name)
[][]Disinfectant Savlon (Cetrimide + Chlorhexidine Gluconate) / Dettol (Chloroxylenol) / Clotec (Hypochloride).

Preparation of 2.5 % v/v Savlon/ Dettol/Clotec

[][]To make 10 L disinfectant solution take 0.250 L Cetrimide + Chlorhexidine Gluconate/ Chloroxylenol / Hypochloride in freshly collected purified water to make up volume up to 10 L.
[][]Stir well to mix the solution properly.
[][]Prepare the disinfectant solution separately in separate bucket for use in different floor.
[][]Maintain the ‘Disinfectant Solution Preparation Record’ (Annexure – I).

Product to Product Cleaning Procedure (Type – A Cleaning) for Production Area

[][]Type – A cleaning is defined as cleaning procedure followed during product to product changeover.
[][]If the unit/equipment is used for same product it has to be cleaned after 72 hours.
[][]Place the status label ‘TO BE CLEANED’ (As per Form No. SOP/QCOM/008/XI) in the Area.
[][]Clean the ceiling, walls, outer surface of light fixtures, supply diffusers (SD) and return grills (RG) first with portable Vacuum cleaner to remove loose dust using a platform trolley, then with wet mop.
[][]Clean the machine/equipment in Production area as per SOP.
[][]Clean the doors, compressed air lines and other service lines with dry cloth.
[][]Clean the glasses with ‘Clear View’ solution and wipe.
[][]Clean the control panels, electrical wires with dry cloth.
[][]Clean toolbox, Batch Manufacturing Record table, log books, SOP holders, hygrometer, stool / chair with dry cloth.
[][]Clean the floor first with dry mop, then with potable water and mop with disinfectant solution. Finally clean with purified water.
[][]Ensure after inspection for absence of any residue of previous product. If any residue of previous product or extraneous matter is found, re-clean the area using above procedure until the area is free of any residue/ extraneous matter.

[][]Remove ‘TO BE CLEANED’ and affix ‘CLEANED’ (As per Form No. SOP/QCOM/008/IX) label in the cleaned area after approval from Quality Compliance.
[][]Record the cleaning activity in ‘Room Cleaning Log Book’ (Annexure – II).

Frequency of Cleaning

[][]During product to product change over.
[][]After 3 days or 72 hours from the date of use of the equipment or area. If any batch is running and 72 hours time exceeds during the batch running period, cleaning shall be done after the batch is finished. If 72 hours time exceeds after cleaning and the equipment or area is not used, use the equipment or area after performing B-type cleaning.

Batch to Batch Cleaning (Type-B Cleaning) for Production area

[][]Type – B cleaning is defined as cleaning procedure followed during batch to batch changeover of a
same product.
[][]Place the equipment status label ‘PARTIALLY CLEANED’ (As per Form No. SOP/QCOM/008/X) in the area.
[][]First clean the floor, ceiling, walls, outer surface of light fixtures, supply diffusers (SD), return grills, (RG) doors and equipment with portable vacuum cleaner to remove the loose dust. [][]Finally clean the floor with wet mop.
[][]Remove ‘PARTIALLY CLEANED’ and affix ‘CLEANED’ (As per Form No. SOP/QCOM/008/IX) label in the area.
[][]Record the cleaning activity in Room Cleaning Log Book.
[][]Frequency of Cleaning
[][]During batch to batch change over

[][]Cleaning at the End of Day’s Operation
[][]Clean external parts of the machine, and operating panel with dry cloth.
[][]Clean the floor first with dry mop, then with potable water and mop with disinfectant solution. Finally clean with purified water.

Annexure:

Annexure I – Disinfectant Solution Preparation Record.
Annexure II – Room Cleaning Log Book.

Pan granulation mechanism, what do you mean by it?

Pan granulation mechanism: The mechanism of granulation process mainly divided into Dry Granulation and Wet Granulation. The formation of granules by Dry Granulation and Wet Granulation is totally different.

The conversion of powder to dry granules bed is totally different based of the machine used in granulation process, same as for Wet Granulation Process. The method of formation of granules in pan granulation mechanism can be described in different ways-

Pan granulation mechanism

Nucleation

In the presence of liquid/water a liquid bridges form an intact mass due to particle contact and adhesion which act as nuclei for further growth of granules. Presence of liquid, powder go through the stages act as nuclei.

Transition

The nuclei can be formed in two ways-One way is- where a single particle can be added to the nuclei and another is two nuclei can be add themselves and the resulted two nuclei reshape by the agitation of podwer bed.

Ball Growth

The resulting powder will grow in time to time and size increase of this spherical granules look like a ball. The ball growth process produces large granules, some this is too much large to use in pharmaceutical purposes. The spheronizing equipment like planetary mixer facilitate some degree of ball growth activities.

The ball growth process can be divided into four classes, stated here-

Coalescence

Two or more granules join together to form a larger granule.

Breakage

Granules are fragmented in to several parts and this parts joint in to another granules and form a layer over the existing granules.

Abrasion Transfer

When granules beds are facing agitation then attrition occur to the materials from granules, then this abraded materials attached/adhere to the other granules increase their size.

Layering

When we add one separate amount of powder to a granules bed then this powder adhere/attached to the granules form a granules layer over the surface and increase the granule size.
