Definitions

  • the present invention relates to resinates of Tofacitinib, fast disintegrating and or quick release pharmaceutical compositions comprising the said resinates and process for the preparation of resinates and compositions.
  • Oral dosage forms containing Tofacitinib have bitter taste. Therefore these are provided in coated form, preferably film coated. Bitter taste of Tofacitinib does not support its use without coating. Fast disintegrating and or quick release taste masked oral dosage forms of Tofacitinib are not available. Therefore there is a need to provide fast disintegrating and or quick release taste masked oral dosage forms containing Tofacitinib.
  • Taste masking is also done by various other means such as formation of new salt, various types of coatings, resinates and inclusion complexes. Rapid melt, Fast melt or quick disintegrating techniques also enable oral dispersion of compositions. Each of these methods is associated with peculiar disadvantages which are method specific.
  • the resin has to be drug compatible. It has to be drug specific otherwise desirable drug release profile may not be achieved. Formulating a stable composition is an important aspect in drug development. Composition in which an improper resin is used can jeopardize drug stability and or drug availability for absorption. Therefore formation of appropriate resinate is a problematic, complicated and challenging process.

  • Tablets produced by Freeze drying technology have high cost of production, besides sensitive to humidity. Their soft, fragile nature renders them unsuitable for conventional blister packing. Useful only for low dose water soluble drugs, poor stability at higher temperature and humidity and very poor physical resistence are additional disadventages. Claritin, Reditab, Dimetapp, Zofran, Lorazepam, Loperamide and few more products are available based on Zydis Tecnology, freeze drying technology.
  • Tablets produced by Molding lack mechanical strength. These often get eroded and damaged during handling or opening the blister pack. Increasing hardness results into undesirable effect on disintegration. Improvement of mechanical strength and disintegration is possible but with huge investments. Orally disintegrating or fast dissolving tablets produced by other technologies necessitate use of robotic techniques such as robotic pick and pack type of packaging systems which are costly.
  • Dysphagia or difficulty in swallowing, is common among all age groups and is more pronounced in infants, small age and geriatric populations. It is also prominent in physically challenged, elderly institutionalized individuals. Swallowing with water is a difficult task for them.
  • Solid dosage forms that can be dissolved in water or suspended in the mouth, promote easy swallowing and are highly desirable for the pediatric, geriatric population and for other patients who prefer the convenience.
