Abstract
Helicobacter pylori reside in the gastric mucus layer and at the mucus-epithelial cell interface wherein access of antimicrobial drug to the infection site is restricted both from the stomach and from the gastric blood supply. The aim of the present study was to develop pectin or gellan gum blended sodium alginate microspheres in order to eradicate gastric Helicobacter pylori. The percentage drug release and mucoadhesion were decrease on increasing the calcium chloride in the formulation dispersion. Curing time significantly effected encapsulation efficiency and was not affected % drug content, % buoyancy, and particle size and drug release. The efficacy of the optimized formulation was evidenced by absence of amplified bacterial gene in treated stomach tissue of Mongolian gerbils as observed using in polymerase chain reaction. The results demonstrate that the developed formulation of Am has potential to eradicate Helicobacter pylori by targeted and prolonged retention at gastric mucosa.

Advances of natural products, bio-actives and novel drug delivery system against emerging viral infections
Due to the increasing prevalence of viral infections and the ability of these human pathogens to develop resistance to current treatment strategies, there is a great need to find and develop new compounds to combat them. These molecules must have low toxicity, specific activity and high bioavailability. The most suitable ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
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
