Article Abstract
Background: Intranasal administration is among the most effective alternatives to deliver drugs directly to the brain and prevent first-pass metabolism. Venlafaxine-loaded liposomes are biocompatible carriers that enhance transport qualities over the nasal mucosa.
Objective: This research aimed to develop, formulate, characterize, and observe the prepared formulation.
Methods: The formulation was developed using the thin-film hydration technique. The response surface plot interrelationship between three independent variables are lipid, cholesterol and polymer and four dependent variables such as particle size, percentage entrapment efficiency, and percentage drug release were ascertained using the Box-Behnken design.
Results: The drug-release chitosan-coated liposomes were reported to have a particle size distribution, entanglement efficiency, and 84%, respectively, of 191 ± 34.71 nm, 94 ± 2.71% and 94 ± 2.71%. According to investigations, liposomes as a delivery system for the nasal route provided a more sustained drug release than the oral dosing form.
Conclusions: The intranasal administration of venlafaxine liposomal vesicles effectively enhanced the absolute bioavailability, retention time, and brain delivery of venlafaxine.

Inhaled and intranasal corticosteroids are widely used in the management of allergic respiratory diseases. Delayed drug hypersensitivity reactions to budesonide are a rare adverse drug reaction characterized by non-immunoglobulin E (IgE)-mediated clinical manifestations, including localized or systemic contact dermatitis, mucosal edema, and paradoxical worsening of pre-existing symptoms. However, such reactions are often underdiagnosed due to atypical presentations.

Neurocognitive disorders represent a significant global health challenge and are characterized by progressive cognitive decline across conditions including Alzheimer's disease, mild cognitive impairment, and diabetes-related cognitive impairment. The hippocampus is essential for learning and memory and requires intact neuroplasticity to maintain cognitive function. Recent evidence has identified the brain insulin signaling pathway as a key regulator of hippocampal neuroplasticity through multiple cellular processes including synaptic plasticity, neurotransmitter regulation, and neuronal survival.

Despite extensive research into Alzheimer's disease (AD), few therapeutic strategies have successfully addressed its core pathology at the synaptic level. Small peptides represent a promising class of therapeutic agents capable of modulating key molecular pathways involved in amyloid toxicity, tau hyperphosphorylation, and synaptic degeneration. Their unique ability to cross biological barriers, interact with intracellular targets, and be modified for enhanced stability positions them as viable candidates for next-generation treatments targeting cognitive decline in AD.

Multiple sclerosis is an autoimmune demyelinating disease, and its effective treatment is a great challenge. As a typical animal model for studying multiple sclerosis, experimental autoimmune encephalomyelitis (EAE) is characterized by inflammation, demyelination, gliosis and axonal loss. Thus, simultaneous regulation of neuroinflammation and remyelination may be a useful strategy against EAE.
