The nasal administration route has been studied for the delivery of active molecules directed to the Central Nervous System, thanks to the anatomical connection between the nasal cavity and the brain. Dimethyl fumarate is used to treat…

The exponential growth of nanotechnology has focused on therapeutic pursuits, notably for brain disorders. Nanocarriers have submicron particle sizes, typically around 500 nm. Over the past few years, interest in nanostructured lipid…

The nose-to-brain (N2B) pathway has garnered attention because it transports drugs directly into the brain. Although recent studies have suggested the necessity of selective drug administration to the olfactory region for effective N2B drug…

Crossing the Blood Brain Barrier constitutes a challenge in drug administration to the brain. In this context, nose-to-brain delivery is explored as an alternative route in the treatment of central nervous system disorders, and…

Central nervous system (CNS) disorders, such as psychiatric disorders, neurodegeneration, chronic pain, stroke, brain tumor, spinal cord injury, and many other CNS diseases, would hugely benefit from specific and potent peptide…

The administration of drugs to the central nervous system (CNS) is primarily controlled by the blood-brain barrier (BBB), a structure that prevents the passage of foreign compounds from the blood to the brain's extracellular fluid. Although…

Purpose: While developing huperzine A (HupA) to explore new approaches to treating Alzheimer’s disease (AD), intranasal administration was proposed as an alternative route to deliver drugs into the brain. This study aimed to prepare…

Phenytoin is a low aqueous solubility antiepileptic drug, but its phosphate ester prodrug fosphenytoin is soluble, although less permeable. In a previous study, the intranasal administration of aqueous-based formulations of fosphenytoin led…

Nasal administration offers a possibility of delivering drugs to the brain. In the present work, nasal drug delivery systems were designed based on cationic Eudragit® EPO (EPO) and anionic Eudragit® L100–55 (L100–55) methacrylate…

Nasal route of administration offers a unique opportunity of brain targeted drug delivery via olfactory and trigeminal pathway, providing effective CNS concentrations at lower doses and lower risk for adverse reactions compared to systemic…
