antiarrhythmic agent

Antiarrhythmic agent-1 (example I), functioning as an antiarrhythmic agent and an IKr potassium channel blocker (IC 50 <1 μM), effectively inhibits cardiac arrhythmias.

Droxicainide is an antiarrhythmic agent, [used] to treat irregular heartbeats.

Gallopamil (Methoxyverapamil) inhibits acid secretion in a concentration-dependent manner with an IC50 of 10.9 μM. Gallopamil is a potent antiarrhythmic and vasodilator agent. Gallopamil (Methoxyverapamil), a methoxy derivative of Verapamil, is a phenylalkylamine calcium antagonist.

Bidisomide (SC40230) is an agent of class I antiarrhythmic.

(-)-Sparteine sulfate pentahydrate ((-)-Sparteine Sulfate) is a class 1a antiarrhythmic agent and sodium channel blocker capable of chelating bivalent calcium and magnesium.

Procaine hydrochloride (Novocaine HCl) is the hydrochloride salt form of procaine, a benzoic acid derivative with local anesthetic and antiarrhythmic properties. Procaine binds to and inhibits voltage-gated sodiumchannels, thereby inhibiting the ionic flux required for the initiation and conduction of impulses. In addition, this agent increases electrical excitation threshold, reduces rate of rise of action potential and slows nerve impulse propagation thereby causing loss of sensation.

Propafenone (Propafenonum) is only found in individuals that have used or taken this drug. It is an antiarrhythmia agent that is particularly effective in ventricular arrhythmias. It also has weak beta-blocking activity. The drug is generally well tolerated. The electrophysiological effect of propafenone manifests itself in a reduction of upstroke velocity (Phase 0) of the monophasic action potential. In Purkinje fibers, and to a lesser extent myocardial fibers, propafenone reduces the fast inward current carried by sodium ions, which is responsible for the drugs antiarrhythmic actions. Diastolic excitability threshold is increased and effective refractory period prolonged. Propafenone reduces spontaneous automaticity and depresses triggered activity. At very high concentrations in vitro, propafenone can inhibit the slow inward current carried by calcium but this calcium antagonist effect probably does not contribute to antiarrhythmic efficacy.

Lidocaine hydrochloride (Lignocaine hydrochloride) is a local anesthetic and cardiac depressant used as an antiarrhythmic agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.

Dofetilide (UK 68789) is a sulfonamide class III antiarrhythmic agent and potassium channel blocker. Dofetilide selectively blocks cardiac ion channels of the rapid component of the delayed rectifier potassium current Ikr. This antiarrhythmic agent prolongs cardiac action potential duration and effective refractory period due to delayed repolarization without affecting conduction velocity. This results in a normal sinus rhythm. Dofetilide is used in the treatment of atrial fibrillation and flutter.

(+)-Sparteine ​​is a quinoline alkaloid extracted from Scotch broom, a sodium channel blocker and a class 1a antiarrhythmic agent. It competitively inhibits the activity of nicotinic acetylcholine receptors in nerve cells and is a ganglionic blocking agent.

Quinidine is a stereoisomer of the antimalarial agent quinine and a class Ia antiarrhythmic agent. for the treatment of abnormal heart rhythms and also malaria.

N-Acetylprocainamide (NAPA), the N-acetylated metabolite of Procainamide, is a Class III antiarrhythmic agent, while procainamide is a Class Ia antiarrhythmic drug.

Nadolol is a non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities. Nadolol competitively blocks beta-1 adrenergic receptors located in the heart and vascular smooth muscle, inhibiting the activities of the catechola

Modecainide is metabolite of Encainide, is an antiarrhythmic agent.

Prifuroline is an agent of antiarrhythmic.

Tocainide hydrochloride, a sodium channel blocker, inhibits the sodium channels in the pain-producing foci in nerve membranes. It is an orally effective antiarrhythmic agent, structurally and pharmacologically similar to lidocaine [1][2].

Hydroquinidine ((+)-Hydroquinidine) is an organic compound, used as an antiarrhythmic agent.

Lubeluzole (dihydrochloride) acts as a neuroprotective agent by blocking neuronal voltage-gated sodium channels and also affects cardiac sodium channels, exhibiting both tonic and blocking effects. This compound is considered promising in the research of antiarrhythmic agents.

Rilozarone has been evaluated as a coronary vasodilator and antiarrhythmic agent.

Nupafant, as an HCl salt, functions as an antiarrhythmic agent.

Tosifen exhibits a relatively weak hypoglycemic effect. It also possesses potential pharmacological activities as an antianginal and antiarrhythmic agent.

Lignocaine N-oxide is a metabolite of Lidocaine, which is an antiarrhythmic and anesthetic agent.

Quinidine is an antiarrhythmic agent. Quinidine is a potent, orally active, selective cytochrome P450db inhibitor. Quinidine is also a blocker of K + channel with an IC 50 of 19.9 μM. Quinidine has potential to be used for malaria research [1] [2] [3].

Aprindine HCl is a Class 1b antiarrhythmic agent used to manage ventricular and supraventricular arrhythmias. In one study, it delayed atrial fibrillation more than digoxin did. It has shown effectiveness when given orally.
