The review authors noted that research into the potential brain benefits of GLP-1 medications needs more research but are optimistic about the future of these drugs in how they may boost brain health.
Drug delivery to the brain is the process of passing therapeutically active molecules across the blood–brain barrier into the brain.This is a complex process that must take into account the complex anatomy of the brain as well as the restrictions imposed by the special junctions of the blood–brain barrier.
The drugs that remain in the passage after mucociliary clearance, enter the brain via three pathways: (1) Olfactory nerve-olfactory bulb-brain; (2) Trigeminal nerve-brain; and (3) Lungs/ Gastrointestinal tract-blood–brain [35] The first and second methods involve the nerves, so they use the neuronal pathway and the third is via systemic ...
This route of administration is often used to bypass the blood-brain barrier because it can prevent important medications from reaching the central nervous system. This injection method is widely used in diseased mice models to study the effect of drugs, plasmid DNA, and viral vectors on the central nervous system.
A large study published in Nature Medicine reviewed the effects of GLP-1 drugs like Ozempic and Mounjaro on 175 different health outcomes. The findings show benefits for brain and heart health ...
Scientists have found a way to help Alzheimer’s drugs seep inside the brain faster — by temporarily breaching its protective shield. “Our goal is to give patients a head start,” by ...
Antimuscarinics are also used as anti-parkinsonian drugs. In parkinsonism, there is imbalance between levels of acetylcholine and dopamine in the brain, involving both increased levels of acetylcholine and degeneration of dopaminergic pathways (nigrostriatal pathway). Thus, in parkinsonism there is decreased level of dopaminergic activity.
The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study showed that most blood concentrations in breastfed infants of mothers taking carbamazepine, oxcarbazepine, valproate, levetiracetam, and topiramate were quite low, especially in relationship to the mother's level and what the fetal level would have been ...
