Abstract
Objective: The objective of this study was to develop and optimize a microflora-triggered colon targeted sustained-release dosage form using Gum Ghatti (GG) and Hydroxypropyl Methylcellulose (HPMC K100).
Methods: GG and HPMC K100 were used to prepare microflora triggered colon targeted sustained- release dosage form. For evaluation, two different tablets comprising metoprolol succinate and mesalamine as an active ingredient were used with the objective of developing a platform technology for various categories of drugs. The tablets were coated with Eudragit® L100 and Eudragit® S100 to provide enteric coating and evaluated for hardness, thickness, friability, weight variation, disintegration, and drug content. in vitro release studies for the prepared tablets were carried out mimicking the physiological transit time. Further, the effects of microflora were evaluated using rat cecal content.
Results: The in vitro dissolution profile of coated matrix tablets showed that 86.03±0.43% of metoprolol succinate and 80.26±0.67% of mesalamine were released at the end of 12 h. The ex vivo dissolution profile of coated matrix tablets showed that 96.50±0.27% of metoprolol succinate and 92.58±0.39% of mesalamine were released at the end of 12 h in the presence of rat ceacal content. The developed formulation was stable when subjected to the standard ICH stability study conditions.
Conclusion: The result of this study showed that gum ghatti together with hydroxypropyl methylcellulose could be successfully used for the preparation of microflora-triggered colon targeted matrix tablets.
Keywords: Gum ghatti, matrix tablet, mesalamine, metoprolol succinate, sustained release, oral drug delivery.

Emerging Nanotherapeutics for Mitigation of Neurodegenerative Disorders
Conditions affecting the central nervous system (CNS) present a significant hurdle due to limited access of both treatments and diagnostic tools for the brain. The blood-brain barrier (BBB) acts as a barrier, restricting the passage of molecules from the bloodstream into the brain. The most formidable challenge facing scientists is ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
