Abstract
Background: Periodontitis is a chronic inflammatory disease, which affects the supporting tissues of the teeth, and without proper treatment it may lead to tooth loss. Antibiotics - administered orally - have been widely used in the treatment of periodontitis. With the conventional administration routes, adequate drug levels cannot be reached in the periodontal pockets and oral application of antimicrobials could lead to side effects. Drug delivery systems containing antibiotics, administered at the site of infection, could possibly help eliminate pathogen bacteria and treat periodontitis.
Objective: The aim of the recent study was to create a locally swellable, biodegradable, biocompatible, mucoadhesive, lipophilic drug delivery system containing antimicrobial drugs which softens at body temperature, accommodate to the shape of the periodontal pocket and can provide extended drug release for at least one week.
Methods: During the formulation, thermoanalytical, consistency, wettability, swelling, degradation and drug release studies were applied to determine the ideal ratios of lipid bases, structure-building components and surface active agent concentrations.
Results and Discussion: The structure-building component cetostearyl alcohol appeared to be the most convenient, thanks to its wettability and mechanical properties, which led to controlled drug release. With the use of ideal concentrations of components (10% surfactant, 40% structure-building component, 32 % lipid base, 15% antimicrobial agent and 3% polymer), sustained drug release can be provided up to nearly 3 weeks.
Keywords: Lipid drug delivery, sustained drug release, swelling, degradation, periodontitis, periodontal pocket, antimicrobial therapy.

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
