Herein we introduce an innovative process for preparation of directly compressible API and excipient agglomerates for extended release formulation of a highly water soluble drug, demonstrated with metformin HCl. Metformin is poorly compressible and currently employs wet granulation for tablet manufacturing, resulting in long cycle times. We have co-processed metformin HCl with hydroxypropyl methylcellulose (HPMC) and sodium carboxymethlycellulose (NaCMC) in solvent medium to generate...

Co-processing is currently of interest in the generation of high-functionality excipients for tablet formulation. In the present study, comparative analysis of the powder and tableting properties of three co-processed starches prepared by three different methods was carried out. The co-processed excipients consisting of maize starch (90%), acacia gum (7.5%) and colloidal silicon dioxide (2.5%) were prepared by co-dispersion (SAS-CD), co-fusion (SAS-CF) and co-granulation (SAS-CG).

Mannitol is a frequently used diluent in the production of tablets due to its non-hygroscopic character and low drug interaction potential. Although the δ-polymorph of mannitol has superior tabletability in comparison to α- and β-mannitol, the latter are most commonly used because large-scale production of δ-mannitol is difficult. Therefore, a continuous method for production of δ-mannitol was developed in the current study. Spray drying an aqueous solution of mannitol and PVP in a ratio...
