Keep ¼ valve of Colloid mill opened till uniform particle size is achieved.

Mix the batch, Fill the Tubes and also perform the primary packing of Tubes at temperature

not more than 25⁰ C and Relative Humidity not more than 40.

Prepare the batch in 2 lots of same size i.e. 2 ´ 350 kgs.

Prepare second lot only after the completion of first batch.

Prepare the second lot in the same manner repeating the procedure of lot one and send

the sample for bulk testing.

Yield:

Expected Practical Yield is 28000  +2% Tube.

Packing Details:

Transfer the cream from storage tank to Semiautomatic Aluminium Tube Filling &

Crimping Machine and start filling and then Crimping of the tubes as per its SOP.

Pack the filled tubes in unit carton.

Pack such 12 tubes in each outer carton.

Seal the outer carton with cello tape.

Pack the 30 outer cartons in specified corrugated box to give a pack size of 30 x 12 x 25 Tubes.

Seal the each corrugated box with adhesive tape and label it properly by affixing the specified label

MANUFACTURING PROCESS (For 350 kg): 

PREPARATION OF GEL:

Add 211 kg of water to the Water Vessel. Operate the machine as per its SOP.

Under constant stirring add 0.350 kg of Methyl Paraben Sodium, 0.875 kg of Propyl

Paraben Sodium, 0.350 kg of E.D.T.A., 0.700 kg of Sodium Metabisulphite and 6.385 kg

of Carbopol- 934 to the same vessel and allow the stirring to achieve uniform smooth gel.

Heat 7.700 kg of Ceto Macrogol – 1000, 6.300 kg of Liquid Paraffin Light and 3.500 kg of Stearic

Acid in Steam Heat Wax Melting Vessel by operating it as per its SOP at temperature 60⁰ C.

Filter the melted base in step no. 2 through Stainless Steel Sieve no. 100 and transfer to the

mixing vessel. Start the machine as per its SOP.

Dissolve 4.263 kg of Diclofenac Diethyl Ammonium in 35.00kg of Isopropyl Alcohol and filter it

and transfer to the bulk batch.

Transfer 17.500 kg of Propylene Glycol to the bulk batch and mix thoroughly for 15 minutes.

Take 38.500 kg of Methyl Salicylate in another Planetary Mixer and add 18.375 kg of Menthol

to it. Operate this Planetary Mixer as per its SOP and mix till the menthol dissolves completely.

Transfer the dissolved solution of Menthol and Methyl Salicylate to the bulk batch.

Mix the whole batch for 60 minutes till uniform cream is achieved.

Send the sample to Quality Control Department for bulk testing.

After approval from Quality Control Department, transfer the cream to the storage tank.

IN-PROCESS CONTROLS: 

The following in-process controls should be maintained during the processing:

Check Raw materials used for manufacturing purpose are all approved materials and have

‘Released’ labels fixed on it.

All weighed Raw materials should be counter-checked by Assistant Manufacturing Chemist.

If any discrepancy is noticed, it should be immediately brought to the notice of Production

Pharmacist and QC/QA Manager.

Physical characteristics of Raw material like colour, odour, and consistency are checked

before compounding.

The total weight of bulk ointment / cream should be checked in the presence of

Assistant Manufacturing Chemist and record the same in Batch Manufacturing Record.

pH of the bulk should be checked and it should be with in specified limits.

Bulk sample should be sent for analysis to Quality Control Department before starting

the filling and sealing stage.

While the tube filling operation is on, the Assistant Manufacturing Chemist should check

weight of net filled quantity per tube at the interval of 30 minutes by checking the tare

weight of empty tube and gross weight of the filled tube. Record for the same should

be kept in Batch Manufacturing Record.

The ‘fill weight’ of ointment or cream per tube should not be less than the labelled amount.

Limit for Weight Variation:  Weight claimed on the carton + 200 mg

Manufacturing Chemist will also ensure that the crimping of the filled Aluminium tubes,

sealing of plastic tubes is appropriate and embossing of batch number and manufacturing

date is conspicuous. Also the quality of embossing will be controlled by adjusting pressure

exerted by the jaws, so that pinholes are not developed on the embossed letters/numbers.

The inner and outer cartons should be checked thoroughly for proper batch coding.

Manufacturing Chemist and Production Pharmacist should randomly check that the correct no.

of inner cartons are being packed in each outer cartons and also the correct number of outer

cartons in each shipper is exactly the same as that shown in proof.

Intimation should be sent to Quality Control Department for finished product sampling and testing.

After the completion of filling and packaging, the coded cartons should be accounted for and

rejected printed material should be destroyed in the presence of QC/QA Manager. Maintain

the destruction of the same in the Batch Manufacturing Record.

It will be ensure that filling or packaging equipment has been properly cleaned.

Filling or packaging of next product should be commenced only after getting the

‘Line Clearance’ of the previous product, from the IPQA.
