Abstract
Capsicum fruit is used for treating skeletomuscular disorders as a counterirritant analgesic around the globe. But its concentration-dependent irritation and concomitant withdrawal of therapy by the patients hampers its therapeutic usefulness. In the present study, a novel nanolipid approach based on elastic phospholipid vesicles was employed to encapsulate a semipurified extract of Bhut Jolokia for topical drug delivery application. The working hypothesis was that encapsulation of irritant extract into nanolipid vesicles may prevent the initial rejection of formulation and the elastic vesicles may facilitate deeper skin penetration over a shorter time period. Surface response methodology was adopted to study the effect of selected independent formulation variables on dependent variables like vesicle size and entrapment efficacy. The prepared formulations were characterized for various physicochemical parameters. The efficacy of the newly developed nonolipid vesicle formulation loaded with semipurified extract of Bhut Jolokia was tested on carrageenan and formaldehyde-induced inflammation as well as Freund’s adjuvant-induced arthritis model. The novel formulations were tested on human volunteers in a Phase I clinical trial and were found to be acceptable. The study indicates that this strategy holds immense potential for topical delivery of the bioactive from Bhut Jolokia and can pave the way for its clinical applications.

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
