In an animal model of complete Freund's adjuvant-induced arthritis, the tofacitinib citrate controlled-release formulation (TCRF) was examined. We examined the impact of TCRF on FCA-induced arthritis in rats, as well as weight alterations and changes in haematological and biochemical indicators. In contrast to the control group, the paw volume reduced and the animals' overall weight increased normally in the TCRF-treated animals, despite the fact that their body weight increased in the FCA-induced arthritis rats. An effective treatment for arthritis-induced haematological and biochemical abnormalities in arthritic rats was found to be TCRF at doses of 2.5, 5, 7, and 10mg/kg/p.o. At both the early and late stages of FCA-induced arthritis, the effects of treating arthritis-prone rats with TCRF showed significant reductions in rat paw edoema volume as well as a restoration of normal haematological and biochemical parameters.

The goal of the project is to use the quality-by-design (QbD) method to create and optimise Tofacitinib citrate matrix tablets with controlled release excipients. The drug's physicochemical parameters, reference product characterisation, QTPP (Quality Target Product Profile), and CQAs were used to start product development (Critical Quality Attributes). Hypromellose (Methocel K100 premium LV CR), Polyethylene Oxide (SentryPolyox WSR N80 LEO), and Magnesium Stearate were used as formulation variables and were optimised together. The complete factorial design of experiment (DOE) with three centre points was used to investigate traditional monolithic controlled release matrix tablets. Using Design-expert12 programme, dissolution was assessed as CQA. At acidic pH, hypromellose with a higher viscosity grade provides a regulated release pattern by retaining the integrity of the medication and preventing rapid drug release. Due to the nonionic nature of the polymer, drug release from the polymer matrices is pH independent. Present monolithic controlled release matrix system the extensive degradation of Tofacitinib Citrate in the acidic condition can be avoided with desired in-vitro drug release.
