Drug delivery to the brain. 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.
Dopamine ( DA, a contraction of 3,4- d ihydr o xy p henethyl amine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. Dopamine constitutes about 80% of the catecholamine content in the brain.
The chemoreceptor trigger zone ( CTZ) is an area of the medulla oblongata that receives inputs from blood -borne drugs or hormones, and communicates with other structures in the vomiting center to initiate vomiting. The CTZ is located within the area postrema, which is on the floor of the fourth ventricle and is outside of the blood–brain ...
