Abstract
Objective: Present work focuses on the use of tamarind gum to develop a drug delivery system making combined use of floating and pulsatile principles, for the chrono-prevention of nocturnal acid breakthrough. Method: The desired aim was achieved by fabricating a floating delivery system bearing time – lagged coating of Tamarindus indica seed polymer for the programmed release of Famotidine. Response Surface Methodology was the statistical tool that was employed for experiment designing, mathematical model generation and optimization study. A 32 full factorial design was used in designing the experiment. % weight ratio of tamarind gum to ethyl cellulose in the coating combination and the coating weight were the independent variables, whereas the lag time for drug release and the cumulative % drug release in 330 minutes were the observed responses. Key findings: Results revealed that both the coating composition and the coating weight significantly affected the release of drug from the dosage form. Conclusion: The optimized formulation prepared according to the computer generated software, Design-Expert® deciphered response which were in close proximity with the experimental responses, thus confirming the robustness and accuracy of the predicted model for the utilization of natural polymer like tamarind gum for the chronotherapeutic treatment of nocturnal acid breakthrough.

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
