Book Description :

The olfactory neuroepithelium is the only part of the central nervous system that is exposed directly to the external environment. Therefore, it is the only non-invasive drug delivery route to the brain. Surface modification of PS nanoparticles with chitosan (C-PS), polysorbate 80 (P80-PS) and polysorbate 80+FCS (P80-FCS-PS) changed the toxicity and distribution of these nanoparticles in olfactory mucosae. In addition, a reduction in nanoparticle diameter from 200nm to 20nm increased nanoparticle mucosal penetration and possibly also their cellular toxicity. In vitro vertical Franz diffusion chamber and in vivo mouse models were adapted to investigate the transport of nanoparticles via the olfactory system. For the in vitro model, preliminary studies found that olfactory epithelium lined the caudal portion of the dorsal nasal turbinate in the porcine nasal cavity. To ensure the scientific validity of the diffusion chamber studies, it was necessary to prove that the experimental procedures themselves (without the addition of nanoparticles) had no effect on the mounted tissue. Therefore, viability and cellular morphology of the dissected olfactory epithelia were assessed prior to application of nanoparticles to tissues. Alamar BlueTM viability and histological findings showed that the diffusion chamber experiment did not affect the olfactory tissue when compared to samples that were not mounted on the apparatus. Citrate buffer (pH6.0) had significantly reduced the viability (PD, Isc and Alamar BlueTM) of the porcine olfactory epithelium compared to SNS buffer (pH7.4) but it did not kill it. Citrate buffer may have depleted the mucosal pH gradient in the epithelium. Overall both SNS buffered and citrate buffered porcine olfactory epithelia were suitable for nanoparticle transport studies in the vertical Franz diffusion cell. The in vitro and in vivo biological models showed surface modification had changed the distribution of nanoparticles within the epithelia. There was good agreement between particle losses from donor chamber, fluorescence microscopy images and stereology results that C-PS particles adhered to extracellular mucus to a greater extent compared to PS and P80-FCS-PS. P80-PS nanoparticles were taken into the nasal epithelial cells to a greater extent than C-PS. Nanoparticles were not transported to the receiver chamber in vitro or the olfactory bulbs in vivo. The size of the nanoparticles was also important. Fluorescence microscopy and stereology showed that greater numbers of 100nm PS and 100nm P80-FCS-PS were taken up into mouse olfactory epithelial cells compared to 200nm diameter equivalents. Larger particles may not have penetrated mucus as effectively as smaller ones. Bright field microscopy images of olfactory epithelia dismounted from the diffusion chamber apparatus after transport study with C-PS nanoparticles showed that these particles caused the greatest amount of cellular damage compared to PS, P80-PS and P80-FCS-PS systems. Greater damage was observed for progressively smaller particles. For example, 20nm C-PS may have accessed subcellular organelles such as mitochondria to cause cell death by oxidative stress. However, similar findings in the mouse model were not observed. It was hypothesised that, unlike the in vitro model, the mouse model may have been able to maintain a pH gradient across the mucous layer by neutralising the acidity from the citrate buffer using blood borne HCO3− ions. This would protect the epithelial cells by causing C-PS to aggregate in the mucus thereby preventing them from accessing the epithelial cells.

Book Description :

With the growing number of patients suffering from central nervous system (CNS) diseases a suitable approach for drug targeting to the brain becomes more and more important. This is a major problem in drug delivery research, due to the tight blood-brain barrier (BBB) that prevents the influx of xenobiotic compounds including drugs from the systemic circulation into the brain. The olfactory neurons, that allow humans and other species to smell, connect the brain and surrounding cerebrospinal fluid (CSF) with the open air that is inhaled via the nasal cavity. This anatomical observation raised the hypothesis that drugs may access the CNS directly following intranasal administration, thereby circumventing the BBB. However, the feasibility of this direct pathway for drug targeting to the brain and CSF is still under debate. One of the reasons is the used method of investigation reported in the literature on drug transport via the nose-brain/CSF route. The majority of these studies are animal studies using extreme experimental conditions, not comparable with the human situation when taking nasal drops or a nasal spray. In this thesis it has been demonstrated for rats that for a variety of drugs (hydrocortisone, estradiol, progesterone, melatonin, vitamin B12 analogue) the amount of the drug that enters the CSF is completely dependent on the amount of drug in the blood, after intranasal and after intravenous administration, and does not take place through the olfactory nerves. For melatonin and for the Vitamin B12 analogue results have been obtained that agree with those of studies using human patients.

Book Description :

Even though the direct nose-to-brain drug delivery has many clinical benefits, there are limited successes in delivering medication aerosols to the olfactory mucosa with standard inhalation devices. In this study, different delivery techniques were assessed in terms of their capacities to deliver drug aerosols to the olfactory epithelium. Specifically, the feasibility of electric field guidance of charged aerosols to the olfactory mucosa was evaluated in an image-based nose model both numerically and experimentally. Multi-sectional nasal cast replicas were fabricated using a 3-D printer to measure the olfactory deposition rates and visualize the deposition distributions. An intranasal deposition test platform was developed that comprised an electric field guidance system, a dry powder charging device, and a point-release nozzle. Numerical simulations were conducted using both ANSYS Fluent and COMSOL. We demonstrated that it is feasible to control charged particles inside the human nose use an external electric field. Both the point-release technique and electric field guidance of drug particles are essential in attaining optimal olfactory doses. Consistent deposition patterns were achieved between in vitro experiments and computational simulations. Future investigations are warrnated for further improvements of olfactory delivery through refining the particle generation, charging, and releasing, and navigation systems.

Book Description :

The development of new CNS drugs is notoriously difficult. Drugs must reach CNS target sites for action and these sites are protected by a number of barriers, the most important being the blood –brain barrier (BBB). Many factors are therefore critical to consider for CNS drug delivery, e.g. active/passive transport across the BBB, intra-brain distribution, and central/systemic pharmacokinetics, to name a few. Neurological disease and trauma conditions add further complexity because CNS barriers, drug distribution and pharmacokinetics are dynamic and often changed by disease/trauma. Knowledge of all these factors and their interplay in different conditions is of utmost importance for proper CNS drug development and disease treatment. In recent years much information has become available for a better understanding of the many factors important for CNS drug delivery and how they interact to affect drug action. This book describes small and large drug delivery to the brain with an emphasis on the physiology of the BBB and the principles and concepts for drug delivery across the BBB and distribution within the brain. It contains methods descriptions for studying drug delivery, routes and approaches of administering drugs into the brain, the influence of disease, and drug industry perspectives. Therewith, it contributes to an in-depth understanding of the interplay between brain (patho)-physiology and drug characteristics. Furthermore, the content is designed to be both cutting-edge and educational, so that the book can be used in high-level training of academic and industry scientists with full references to original publications. ​

Book Description :

The nasal route has primarily been used to deliver drugs for the treatment of local diseases such as nasal infections, nasal congestion and allergies. The nasal route can also be used as a non-invasive alternative route to deliver drugs systemically when a rapid onset of action and/or avoidance of hepatic metabolism are desired. Moreover, there is a growing interest in the use of this route for direct transport of drugs from the nose to the brain. Most of the drugs that have been studied for nasal delivery are either small molecules which are lipophilic enough to passively diffuse through the nasal epithelia or macromolecules where bioavailabilities less than 1% are clinically effective and acceptable. This study focused on identifying carrier proteins or transporters in the nasal mucosa that could improve the absorption of specific drug substrates across the nasal respiratory and olfactory epithelia. The presence of drug transporters in the nasal mucosa of humans and commonly used animal models were investigated. DNA microarray results for nasal samples from humans and two commonly used models, mice and rats, were obtained from GenBank and were analyzed in collaboration with the University of Iowa Center for Bioinformatics and Computational Biology. While cow tissues are frequently used in in-vitro nasal permeability analyses, there is limited information available in GenBank for this species. Both DNA microarray analysis and RT-PCR were performed on bovine nasal explants to determine transporter expression. Good agreement between the microarray and RT-PCR results was observed. While human and three animal species commonly used as models in nasal drug delivery research (mouse, rat, and cow) show similar patterns of expression for several transporters, interspecies differences in the level of expression were observed. Therefore, the expression level of transporters remains a factor to consider when translating results obtained using animal models to humans. The nucleoside transporter family was selected for further evaluation of the potential to improve the nasal absorption of substrates. Nucleoside transporters are integral proteins responsible for mediating and facilitating the flux of nucleosides across cellular membranes; they are also known to be responsible for the uptake of nucleoside analog drugs such as anti-cancer and anti-viral agents. RT-PCR and Western blotting were used to verify the presence of two transporter subtypes, ENT1 and CNT3, in the bovine nasal respiratory and olfactory mucosa. The expression level of both transporters in the respiratory mucosa was comparable to that in the olfactory mucosa. Using immunohistochemistry, ENT1 and CNT3 were found to be localized primarily at the apical surface of the nasal epithelial cells. This indicates that the nasal epithelium likely absorbs exogenous nucleosides for intracellular uses such as nucleic acid synthesis and regulating other cellular activities. The contribution of the nucleoside transporters to the permeation of a nucleoside analogue drug, alovudine, across the nasal epithelia was also studied. The transport of alovudine showed a non-linear increase with increasing donor concentration over the range of 50 to 3000 μM which suggests that nucleoside transporters play a role in its uptake. Polarized transport was not observed suggesting that the facilitative nature of ENT1 plays a major role in alovudine transport. S-(4-nitrobenzyl)-6-thioinosine (NBMPR), an ENT1 inhibitor, incompletely decreased alovudine permeability across the nasal mucosa. This demonstrates that at least one transporter, ENT, plays a significant role in the uptake of this nucleoside drug across the nasal mucosa.
