Intranasal creatine administration increases brain creatine level and improves Barnes maze performance in rats

open access: yesBrain Research Bulletin, 2023
While skeletal muscle creatine levels can be enhanced by exogenous creatine supplementation, the elevation of brain creatine levels with oral creatine administration remains a challenge due to a lack of effective transportation of creatine through the ...

Utility of a Novel Micro-Spraying Device for Intranasal Administration of Drug Solutions to Mice

open access: yesPharmaceutics, 2023
Intranasal administration has attracted attention as a means of delivering drugs because it bypasses the blood–brain barrier. However, conventional intranasal administration of drug solutions to mice using the micropipette method (MP method) is ...

Intranasal administration of collagenase develops cerebral microbleeds and vascular dementia in mice: In vivo pilot study

open access: yesBrain Hemorrhages, 2023
Objective: To establish a new animal model of lobar cerebral microbleeds (CMBs), we examined whether intranasal administration of collagenase induced CMBs in young mice which did not have hypertensive pathologic features. Methods: We used thirty-two male

Intranasal Administration of N-acetyl-L-cysteine Combined with Cell-Penetrating Peptide-Modified Polymer Nanomicelles as a Potential Therapeutic Approach for Amyotrophic Lateral Sclerosis

open access: yesPharmaceutics, 2022
Intranasal administration is a promising route for direct drug delivery to the brain; its combination with nanocarriers enhances delivery. We have previously shown that intranasal administration combined with PEG-PCL-Tat (a nanocarrier) efficiently ...

Intranasal Vaccination With Recombinant Antigen-FLIPr Fusion Protein Alone Induces Long-Lasting Systemic Antibody Responses and Broad T Cell Responses

open access: yesFrontiers in Immunology, 2021
A simple formulation is urgently needed for mucosal vaccine development. We employed formyl peptide receptor-like 1 inhibitory protein (FLIPr), an FcγR antagonist secreted by Staphylococcus aureus, as a vector to target ovalbumin (OVA) to dendritic cells

Intranasal administration of acetylcholinesterase inhibitors [PDF]

open access: yesBMC Neuroscience, 2008
This short review outlines the rationale, challenges, and opportunities for intranasal acetylcholinesterases, in particular galantamine. An in vitro screening model facilitated the development of a therapeutically viable formulation. In vivo testing confirmed achievement of therapeutically relevant drug levels that matched or exceeded those for oral ...
