Sodium channel blockers are also used as local anesthetics and anticonvulsants. [5] Sodium channel blockers have been proposed for use in the treatment of cystic fibrosis, [6] but current evidence is mixed. [7] It has been suggested that the analgesic effects of some antidepressants may be mediated in part via sodium channel blockade. [8]
Sodium channel inhibitors are used as both antiepileptics and antiarrhythmics, as they can inhibit the hyper-excitable tissues in a patient. [22] Introducing specific sodium channel blockers into a tissue allows for the preferential binding of the blocker to sodium channels, which results in an ultimate inhibition of the flow of sodium into the ...
An epithelial sodium channel blocker is a sodium channel blocker that is selective for the epithelial sodium channel. An example is amiloride , which is used in the treatment of hypertension . [ 1 ]
This is a list of neurosteroids, or natural and synthetic steroids that are active on the mammalian nervous system through receptors other than steroid hormone receptors. It includes inhibitory , excitatory , and neurotrophic neurosteroids as well as pheromones and vomeropherines .
Carbamazepine is a sodium channel blocker. [37] It binds preferentially to voltage-gated sodium channels in their inactive conformation, which prevents repetitive and sustained firing of an action potential. Carbamazepine has effects on serotonin systems but the relevance to its antiseizure effects is uncertain.
Because Liddle phenotype usually involves an upregulation of ENaC channels, leading to retention of sodium and water and to hypokalemia, amiloride is useful as an ENaC channel inhibitor due to its promotion of sodium excretion and its potassium-sparing effects, restoring potassium to normal levels. [13]
It is a calcium channel blocker of the dihydropyridine type. [2] Nifedipine is taken by mouth and comes in fast- and slow-release formulations. [2] Common side effects include lightheadedness, headache, feeling tired, leg swelling, cough, and shortness of breath. [2] Serious side effects may include low blood pressure and heart failure. [2]
Steroidogenesis inhibitors are analogous in effect and use to antigonadotropins (which specifically inhibit gonadal sex steroid production), but work via a different mechanism of action; whereas antigonadotropins suppress gonadal production of sex steroids by effecting negative feedback on and thereby suppressing the hypothalamic–pituitary ...
