Ceftriaxone, sold under the brand name Rocephin, is a third-generation cephalosporin antibiotic used for the treatment of a number of bacterial infections. [4] These include middle ear infections, endocarditis, meningitis, pneumonia, bone and joint infections, intra-abdominal infections, skin infections, urinary tract infections, gonorrhea, and pelvic inflammatory disease. [4]
They also have a greater resistance to β-lactamases than the third-generation cephalosporins. Many can cross the blood–brain barrier and are effective in meningitis. They are also used against Pseudomonas aeruginosa. [citation needed] Cefiderocol has been called a fourth-generation cephalosporin by only one source as of November 2019. [33]
The blood–brain barrier (BBB) is a highly selective semipermeable border of endothelial cells that regulates the transfer of solutes and chemicals between the circulatory system and the central nervous system, thus protecting the brain from harmful or unwanted substances in the blood. [1]
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.
In comparison to the known gut microbiome, a brain microbiome would likely have several orders of magnitude fewer microbes. [2] Microbes would not necessarily need to reproduce to maintain a population within the brain, but would only need to leak through the blood-brain barrier at a low level. [2]
This route is also used to introduce drugs that fight certain infections, particularly post-neurosurgical. Typically, the drug is given this way to avoid being stopped by the blood–brain barrier, as it may not be able to pass into the brain when given orally. Drugs given by the intrathecal route often have to be compounded specially by a ...
The blood–brain barrier (BBB) is protected by a network of blood vessels and tissue that shields it from harmful substances. This protection also stops anti-cancer drugs from getting to the brain. To treat brain tumours and other brain related diseases, [ 2 ] [ 3 ] blood–brain barrier disruption is needed for the anti-cancer drugs to be ...
The blood brain barrier (BBB) has historically proved to be a very difficult obstacle to overcome when aiming to deliver a drug to the brain. In order to overcome the difficulties in delivering therapeutic levels of drug past the BBB, drugs had to either be lipophilic molecules with a molecular weight below 600 Da or be transported across the BBB using some sort of cellular transport system.
