Optimisation of the composition and production of mannitol/microcrystalline cellulose tablets

Mixtures of mannitol and microcrystalline cellulose (MCC) were investigated on a small-production scale by granulation in a high-shear mixer and compression into tablets. For both excipients only a few cases of incompatibilities with active ingredients are known. Tablets with only MCC as the filler excipient have mostly inferior strength and tablets of only mannitol disintegrate slowly. However, a combination of both excipients resulted in sufficiently rapid disintegrating tablets with acceptable strength. The composition of the tablet mixture and the process of tablet manufacturing were optimised using statistical techniques. Next to the effects of the amounts of MCC and hydroxypropylcellulose (HPC) in the composition, the effects of the amount of water and the granulation time were evaluated. For the production of tablets both the effects of moisture content in the granules and compression force were studied. Simultaneous optimisation of crushing strength, disintegration time and ejection force of the tablets was carried out to find optimal regions in the design space for these tablet properties. In conclusion, mannitol/MCC mixtures can be considered as an interesting alternative in case classical excipients cannot be selected in formulation development, due to chemical incompatibilities with active ingredients or inferior physical characteristics.

New method of preparing high-porosity rapidly saliva soluble compressed tablets using mannitol with camphor,a subliming material

Compressed tablets of a water-soluble material, prepared using mannitol, did not rapidly dissolve in water since it is difficult for water to penetrate into the tablets due to their low porosity. To increase the porosity of the tablets which are prepared by direct compression using mannitol, we developed a novel method whereby camphor, a subliming material, is removed by sublimation from compressed tablets prepared using a mixture of mannitol and camphor. A high porosity was achieved due to the formation of many pores where camphor particles previously existed in the compressed mannitol tablets prior to sublimation of the camphor. These compressed tablets which have high porosity (approximately 30%) rapidly dissolved within 15 s in saliva in the mouth. We developed a direct compression method for the preparation, using mannitol and camphor, of a meclizine (antidinic agent) tablet with high porosity which dissolves rapidly in saliva.

Change in porosity parameters of lactose, glucose and mannitol granules caused by low compression force

The change in porosity parameters, i.e., total pore volume, porosity percentage and pore volume size distribution of lactose, glucose and mannitol granules caused by compression with a low force was investigated. In compression, fragmentation of lactose and glucose granules increased total pore volume and porosity percentage, whereas the total pore volume and porosity percentage of mannitol granules was clearly decreased. This was due to the highly porous structure of mannitol granules, which densified easily in compression. Lactose and glucose granules were shown to resist deformation more. The pore volume size distributions of lactose and glucose tablets showed that large pores ( > 14 μm) decreased in size. For mannitol tablets, the large pores vanished and simultaneously the small granule pores ( < 14 μm) reduced in size. The features of the pore structure of granules were detected in the pore volume size distributions of compressed tablets. Mercury porosimetry, assisted by scanning electron microscopy, was shown to be an adequate method to evaluate the deformation of granules in compression.

Development of manufacturing method for rapidly disintegrating oral tablets using the crystalline transition of amorphous sucrose

The industrial manufacturing of rapidly disintegrating oral tablets with a sufficient tensile strength was investigated. The manufacturing method of the tablets involved the crystalline transition of amorphous sucrose that was produced in the process of fluidized bed granulation of mannitol using sucrose solution as a binder. The aim of this article was to clarify the usefulness of amorphous sucrose formed during the granulation for the rapidly disintegrating oral tablets manufacturing, and to investigate the effects of crystalline transition of the amorphous sucrose in granules on the characteristics of the resultant tablets prepared by this crystalline transition (CT) method. The X-ray diffraction measurement and thermal analysis showed that amorphous sucrose was effectively formed in granules consisting of 95% mannitol and 5% sucrose when the granulation was performed on the condition of water content of 4%. The tensile strength of tablets comprised of the granules, which were compressed before the crystallization of amorphous sucrose, increased remarkably after storage, because new internal solid bridges were formed in the tablets as a result of the crystallization. We conclude that rapidly disintegrating oral tablets can effectively be manufactured by the CT method using the granules obtained by the fluidized bed granulation method.
