A cerebral vasodilator is a drug which acts as a vasodilator in the brain. [1] [2] They are used to improve blood flow in people with cerebrovascular insufficiency and to treat neurological disorders secondary to this condition. [2] A number of different cerebral vasodilators exist.
These drugs increase the permeability of the blood–brain barrier temporarily by increasing the osmotic pressure in the blood which loosens the tight junctions between the endothelial cells. By loosening the tight junctions normal injection of drugs through an [IV] can take place and be effective to enter the brain. [ 8 ]
Piracetam is thought to increase cell membrane permeability. [24] [25] Piracetam may exert its global effect on brain neurotransmission via modulation of ion channels (i.e., Na +, K +). [20] It has been found to increase oxygen consumption in the brain, apparently in connection to ATP metabolism, and increases the activity of adenylate kinase ...
Cerebral blood flow (CBF) is the blood supply to the brain in a given period of time. [8] In an adult, CBF is typically 750 millilitres per minute or 15.8 ± 5.7% of the cardiac output. [9] This equates to an average perfusion of 50 to 54 millilitres of blood per 100 grams of brain tissue per minute. [10] [11] [12]
The therapy involves breathing pure oxygen in a chamber with above-normal air pressure. Some treatments are endorsed by medical experts, but not all. Hyperbaric oxygen therapy is touted as ...
Struggling, restlessness, and seizures can increase metabolic demands and oxygen consumption, as well as increasing blood pressure. [31] [36] Analgesia and sedation are used to reduce agitation and metabolic needs of the brain, but these medications may cause low blood pressure and other side effects. [10]
