Sodium Channel Blockers: Types, Benefits, and Side Effects
2024年10月21日 · Sodium channel blockers are medications that help reduce abnormal electrical activity in the heart. They can also lower the risk of severe complications such as stroke or...
Sodium channel blocker - Wikipedia
Sodium channel blockers are drugs which impair the conduction of sodium ions (Na +) through sodium channels. [1] The following naturally-produced substances block sodium channels by binding to and occluding the extracellular pore opening of the channel:
Class I Antiarrhythmics (Sodium-Channel Blockers)
Sodium-channel blockers comprise the Class I antiarrhythmic compounds according to the Vaughan-Williams classification scheme. These drugs bind to and block fast sodium channels that are responsible for rapid depolarization (phase 0) of fast-response cardiac action potentials.
Antiarrhythmic Drugs: Types, Uses and Side Effects
Class I, sodium channel blockers: These drugs prevent sodium from getting through cell membranes. This can slow electrical impulses in the heart muscle. Examples include disopyramide, flecainide, mexiletine, propafenone and quinidine.
Sodium Channel Blockers - DrugBank Online
A class of drugs that act by inhibition of sodium influx through cell membranes. Blockade of sodium channels slows the rate and amplitude of initial rapid depolarization, reduces cell excitability, and reduces conduction velocity. An anti-anginal drug …
Class I antiarrhythmics: Sodium channel blockers - Osmosis
We’ll focus on class I antiarrhythmics which are further broken down into 1a, 1b, and 1c. All three groups work on Na+ channels in the cardiac myocytes, so class I medications are also called Na+ channel blockers.
17.2 Class I: Sodium Channel Blockers - Pharmacology for ...
Class I antidysrhythmic drugs are known as sodium channel blockers. They block sodium channels in conduction tissue and myocytes. Sodium channels are responsible for the depolarization of cardiac cells, and blocking these channels leads to slower conduction and a longer refractory period between impulses.
Mechanism of sodium channel block by local anesthetics ...
Local anesthetics, antiarrhythmics, and anticonvulsants include both charged and electroneutral compounds that block voltage-gated sodium channels. Prior studies have revealed a common drug-binding region within the pore, but details about the binding sites and mechanism of …
Sodium Channel Blocker - an overview | ScienceDirect Topics
Sodium channel blockers are used as primary therapy or adjunctive treatment of processes such as trigeminal neuralgia (TN), CRPS, PDN, radicular extremity pain, chemotherapy-induced peripheral neuropathy, and PHN.
Sodium channel blockers for the treatment of neuropathic pain
Drugs that block voltage-gated sodium channels are efficacious in the management of neuropathic pain. Accordingly, this class of ion channels has been a major focus of analgesic research both in academia and in the pharmaceutical/biotechnology industry.
