Pharmaceutical formulation process

The manufacturing processes of drugs differ on the basis of their sources of origin or medium use.  Different approaches of formulations and manufacturing are used for different groups of drugs. 



Basically, the formulation process involves the blending of the different bulk drug constituents in pre-determined proportions. The production of solid drugs, such as tablets, involves mixing/milling, drying and table ting. The manufacturing operations of capsules include powder mixture preparation, filling of powder into gelatin capsule and sealing. A liquid formulation such as syrup involves basically mixing and filling. The manufacture of sterile drugs like vials and ampoules includes, in addition to basic formulation operations, sterilization process.
