Procedure
- Mixing:
- Pass Metoprolol Succinate and MCCPH102, Empress SR through 60 # in sifter and aerosil in #40 sifter
- mix it insuitable blender for 15 mins.
- Binder Preparation and Binding:
- Dissolve PVPK30 in IPA and prepare clear solution
- Now bind the Premix using binder prepared in Step 1 and if necessary add additional IPA to get a wet mass ,
- Pass the weight mass through #12 sieve to get uniform wet granules and dry it at inlet temp of 40o c
- Now size the granules using #30 to get dry granules
- Lubrication:
- Collect the dried granules in blender
- Sift the material Talc, EmpressSR, Mg Stearate and Aerosil with #60 sieve.
- Mix the lubricants in Dried granules and compress the tablet with following parameter
- Mixing:
