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]
For example, TTX can bind and inactivate voltage-gated sodium channels, despite the fact that TTX is much larger and chemically different than sodium ions. Given the disparities in size and chemical properties between TTX and a sodium ion, this is an example of structure being used to block usually specific channels.
Disopyramide (INN, trade names Norpace and Rythmodan) is an antiarrhythmic medication used in the treatment of ventricular tachycardia. [2] It is a sodium channel blocker and is classified as a Class 1a anti-arrhythmic agent. [3] [4] Disopyramide has a negative inotropic effect on the ventricular myocardium, significantly decreasing the ...
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.
Beta-blockers with intrinsic sympathomimetic activity: acebutolol, pindolol; Some common side effects include increased airway resistance for non-selective beta-blockers, exacerbation of peripheral vascular diseases, and hypotension [15] Beta-blockers are contraindicated in patients with second- or third-degree atrioventricular block.
Benzonatate was first made available in the United States in 1958 as a prescription medication for the treatment of cough in individuals over the age of 10. [24] [25] There is a variety of prescription opioid-based cough relievers, such as hydrocodone and codeine, but have unwanted side effects and potential of abuse and diversion. [22]
