Yes
Yes, dopamine can cross the blood-brain barrier.
Netilmicin does not cross the blood-brain barrier.
Large molecules, such as proteins and most drugs, cannot easily cross the blood-brain barrier.
Insulin does crosses the blood brain barrier. Insulin crosses the blood brain barrier through the process of receptor-mediated transcytosis.
Yes. Valium (diazepam) does indeed cross the blood brain barrier. It is one of the more lipophilic of the benzodiazepine medications.
Acetohexamide crosses the blood-brain barrier, which is why it is not prescribed to patients who might show sensitivity to this action.
It is water soluble...
The blood barrier is located in the brain. It is known as the blood brain barrier and is located in the middle of the ventricular system. It keeps many substances from being able to cross into the brain.
Meningitis, by definition, is an inflammatory process of the meninges, which constitute the blood brain barrier (BBB). Inflammation makes the blood brain barrier more permeable to chemicals, such as antibiotics. Under normal circumstances, penicillin does not cross the BBB very well, but when inflamed, it can cross more readily.
Antidepressants, alcohol, cocaine
Yes. Atropine is a tertiary amine and is able to cross the BBB.
Examples of antibiotics that can cross the blood-brain barrier include penicillin, ceftriaxone, and meropenem. These antibiotics are often used to treat bacterial infections in the central nervous system (CNS) such as meningitis and brain abscesses. It is important for these antibiotics to effectively penetrate the blood-brain barrier to reach the site of infection in the brain and spinal cord.
