  • Manufacturing Procedure :
    • Manufacturing procedure in brief comprise of following steps:
      • Step – I:-MILLING : Mill Citric Acid Monohydrate through comminuting mill fitted with 5 mm perforated sieve at hammer forward orientation and at medium  speed and sift through   vibro sifter fitted with sieve of mesh size 100 & divide in two lots (2.0 + 1.0 kg).
      • Step – II:-SIFTING : Sift Dextromethorphan Hydrobromide and Chlorphenamine Maleate complex , Phenylephrine Hydrochloride complex, Mannitol , Silica, Colloidal Anhydrous, Indion 294 ,  Talc, Magnesium Stearate, Croscarmellose Sodium, Pharmaburst B2 through Vibro Sifter fitted with sieve of mesh size 40 collect the sifted material in IPCs.
      • Step – III:-SIFTING : Sift  Sunset Yellow Colour Lake through Vibro Sifter fitted with sieve of mesh size 100 collect the sifted material in IPCs.
      • Step – VI:Take Citric Acid Monohydrate (2.0 kg) from step- I and manually mix with the bulk of step – III  for 2-3 minutes.
      • Step – V:DRY MIXING : Perform dry mixing  of  materials of step – II & step -IV  in Blender’s bin. ( mix for  10 minutes at 6 rpm)
      • Step – VI:SLUGGING : Slug the mass of step – V in Roll-Compactor, adjust and record Feed screw rate (rpm) and speed of rollers (rpm) and weigh the slugs.
      • Step – VII: DESLUGGING : Mill the mass of step – VI by Multimill/ Comminuting mill fitted with 3.0 mm Screen at knife forward orientation and at slow speed
      • Step – VIII: SIFTING :Sift the milled mass through Vibro Sifter fitted with sieve of mesh size 16 and pass the retention through comminuting mill fitted with 3.0 mm Screen at knife forward orientation and at slow speed , repeat the above process till all the material of step- VII passed through sieve of mesh size 16 .
      • Step – IX:SIFTING :
      • a) Sift the material of step – VIII through Vibro Sifter fitted with sieve of mesh size                         60,collect and weigh the retention.
      • b) If the retention of step IXa is more than or equal to  80 % proceed for lubrication step.

If the retention percentage is less than 80 % then repeat process  steps (7.1.6 to 7.1.8) for  retention  until retention  % is equal or more than  80 % ,if it is equal or more  80 % then directly proceed for next  step

  • Step – X:SIFTING/LUBRICATION OF GRANULES :
  • a) Sift Colour Lake of Sunset Yellow through Vibro Sifter fitted with sieve of mesh size 100
  • b) Sift Silica, Colloidal Anhydrous , Orange Flavour , Aspartame, Talc, Magnesium Stearate, Croscarmellose Sodium  through Vibro Sifter fitted with sieve of mesh size 40.
  • c) Geometrically mix Citric acid monohydrate of step -I with step -X a&b manually for 3-5 minutes.
  • d) Geometrically mix the granules  of step X c with step – IX then transfer  the bulk  to Blender’s Bin and    Blend for 10 minutes at 6 rpm.
  • Step – XI: WEIGHING :Weighing of lubricated granules is done  by using a calibrated balance and calculate the actual  .
  • SAMPLING : Inform to IPQA Department through In-process Analytical Request  to collect the sample of blended granules of step – XI, IPQA personnel  send the sample to Quality Control Department for testing as per In-process Specification.
  • Step – XII:COMPRESSION : After getting approval from IPQA Department, compress the lubricated blend of step XI, into tablets of required specification using 37 station compression machine fitted with round  dies, plain punches  (12.00 ± 0.05 mm).

                                                  COMPRESSION PARAMETERS

Critical Process Steps and Process Parameters for Validation with Justification:

Process Step Process Parameters Justification
DISPENSING % RH & Dispensing aids Influence the stability and manufacturing of product
SIFTING Sieve size, sifting time and integrity of sieve. To evaluate the sifting time during sifting process
DRY-MIXING Dry-mixing time, and Blending rpm. After completion of sifting, the process of dry mixing is evaluated for Homogeneity of drugs through sampling of the mixed blend after 10 minutes at 6 rpm. Blending is done using Conta Blender.  This process step is evaluated for adequate blending time assessment through the determination of blend uniformity analysis of samples collected from different location. It can influence both the content uniformity & assay of product.
SLUGGING Feed screw rate (rpm), Speed of rollers (rpm). To record and evaluate the variability of critical process variables for process step of slugging to achieve granules of desired properties.
DESLUGGING/ MILLING Feed rate of slugs. Milling speed, Blade orientation and Screen size. Effective deslugging is achieved by adjusting the feed rate to 10.0 kg/ 10-20 minutes.
SIFTING Sieve size, sifting time and integrity of sieve. To record and evaluate the variability of critical process variables during sifting.
LUBRICATION/ BLENDING Blender speed (rpm) and Blending time etc. After addition of sifted Post granulation ingredients to the granules; blending is  done using Conta Blender. This process step is evaluated for adequate blending of the lubricant by sampling of the blended granules from different locations from the blender bin after 8 minutes of blending at 6 rpm. The assessment is taken through the determination of blend uniformity analysis in samples collected from different locations. The blend to be monitored for Bulk Density & Tapped Density, angle of repose, Compressibility Index and Hausner Ratio on the composite sample collected after  10  minutes at 6 rpm to determine the flow properties of the blended granules. Sampling is done by using suitable sampling thief.
COMPRESSION  Machine Speed, Description, Average Weight, Uniformity of Weight, Diameter Thickness, Disintegration time, Uniformity of dispersion, Hardness, Friability etc. Tablets are Compressed using 37 Station Double Rotary Compression Machine. This process is evaluated through sampling the compressed tablets from both sides (left & right) produced at different intervals (Start, Middle and towards the end of compression). Samples are checked for the determination of Description, Average Weight, Uniformity of Weight, Diameter Thickness, Disintegration time, Uniformity of dispersion, Hardness, Friability against the established specifications at IPQA Laboratory

Compressed tablets are subjected for the determination of Uniformity of dosage units (by content uniformity & Dissolution.

One composite sample is subjected for complete analysis as per the established
