Abstract
Background: The transdermal dosage forms presented a limited usage for a long time, for it was believed that the stratum corneum, the outermost layer of epidermis, made it impracticable the permeation of medications through the skin. Studies exploring this area came up with strategies to overcome this barrier; for example, creating a transdermal vehicle to facilitate the drug absorption.
Objective: This study aimed to evaluate a new transdermal vehicle through the comparison of its permeation profile and the profile of commercial products, using nimesulide and piroxicam, non steroidal anti-inflammatory drugs.
Methods: Four different products were evaluated: nimesulide and piroxicam compounded with the new vehicle (emulsion) and commercial nimesulide and piroxicam gels. Ex vivo permeation experiments using Franz-type diffusion cell equipment were conducted, using human skin as membrane. For evaluation of permeated active pharmaceutical ingredients concentrations, we performed quantification from the receptor solution, stratum corneum and viable epidermis + dermis, through high-performance liquid chromatography analyses.
Results: The new vehicle promoted increased permeation of active pharmaceutical ingredients through the viable epidermis and dermis, when compared to commercial products, but the stratum corrneum continued to keep the highest retention.
Conclusion: The innovative vehicle was capable of enhancing the transdermal absorption of active pharmaceutical ingredients from the compounded formulations, thus, demonstrating the capability thereof to improve the permeability of active pharmaceutical ingredients by transdermal use.
Keywords: Nimesulide, NSAIDS, permeation studies, piroxicam, stratum corneum, transdermal vehicle, viable epidermis.

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
