Present review highlights the potential of nasal mucosa as an administration route for targeting the central nervous system, the brain. Targeted drug delivery seeks to concentrate the medication in the tissues of interest while reducing the relative concentration of medication in the remaining tissues. Thus improving efficacy of the drug and reducing side effects. The nasal mucosa when compared...

BACKGROUND The objective of this work was to review the literature concerning the distribution of topical therapeutics to the sinuses versus nasal cavity regarding: surgical state, delivery device, head position, and nasal anatomy and to provide evidence-based recommendations. METHODS A systematic review was conducted using Medline, EMBASE, and Cochrane databases to perform a Medical Subject ...

Parenteral administration of proteins/peptides requires repeated injections because of their extremely short biological half-life. Daily multiple injections are highly risky and require close medical supervision. Therefore, the delivery of proteins and peptides by routes other than parenteral route h s gained much attention in recent years. As a drug delivery route, nasal cavity offers several ...

Efficient vaccine delivery to mucosal tissues including mucosa-associated lymphoid tissues is essential for the development of mucosal vaccine. We previously reported that claudin-4 was highly expressed on the epithelium of nasopharynx-associated lymphoid tissue (NALT) and thus claudin-4-targeting using C-terminal fragment of Clostridium perfringens enterotoxin (C-CPE) effectively delivered fus...

The human nose has the potential to be an alternative route for the systemic delivery of a wide range of therapeutic agents. The richly supplied vascular nature of the nasal mucosa and its high drug permeation makes it a potential route for the administration of many drugs including proteins, peptides and vaccines. Nasal route is most suitable for those drugs which cannot be administered orally...

A time-course study was performed to assess lung concentrations and bioactivities of a fully human monoclonal antibody (mAb) targeting Pseudomonas aeruginosa (PA) flagella type b (LST-007) following intra-nasal administration. Intra-nasal administration of LST-007 (5 mg/kg) resulted in high mAb concentrations (11 μg/ml) within the bronchoalveolar lavage (BAL) fluid at 15 min post-administration...

BACKGROUND Inhaled nitric oxide (INO) has been used with heated and humidified high-flow nasal cannula (HFNC), nasal CPAP and several forms of noninvasive ventilation (NIV). This study was designed to evaluate the delivered dose of INO, level of NO2 generation, and effect of net gas delivery (addition of INO to the ventilator circuit--gas removed for sampling) on lung pressure at different NO d...

The aim of this paper is the preparation and characterization of drug delivery systems for a potential brain delivery by intranasal administration. It is possible to reach the central nervous system with alternative routes through which therapeutic agents can bypass the blood brain barrier: that is the nasal administration. Intranasal drug administration is non-invasive and it could be a promis...

BACKGROUND Despite the prevalence of rhinosinusitis that affects 10%-15% of the population, current inhalation therapy shows limited efficacy. Standard devices deliver <5% of the drugs to the sinuses due to the complexity of nose structure, secluded location of the sinus, poor ventilation, and lack of control of particle motions inside the nasal cavity. METHODS An electric-guided delivery sys...
