Propafenone Hydrochloride

Описание

Propafenone hydrochloride is a class I anti-arrhythmic agent with basic local anaesthetic and membrane-stabilizing properties. Some P-adrenergic blocking action has also been described. Propafenone decreases the depolarization velocity and slows conduction in the His-Purkinje system with resultant increase in the PR interval and the QRS complex. Propafenone is used in the treatment of paroxysmal supraventricular tachycardias and ventricular arrhythmias.
Propafenone should not be used in uncontrolled cardiac failure, severe obstructive pulmonary disease or marked hypotension. Propafenone may worsen myasthenia gravis.

Использование

Propafenone hydrochloride is a class IC antiarrhythmic agent used for the management of severe ventricular and supraventricular arrhythmias. It has beta-blocking and weak calcium channel blocking properties, as well as some negative inotropic activity. Propafenone is in a class of medications called antiarrhythmics. It works by acting on the heart muscle to improve the heart's rhythm.

Использование

Sodium channel blocker. Antiarrhythmic (class IC)

Определение

ChEBI: Propafenone hydrochloride is a hydrochloride that is the monohydrochloride salt of propafenone. It is a class 1C antiarrhythmic drug with local anesthetic effects, and is used in the management of supraventricular and ventricular arrhythmias. It has a role as an anti-arrhythmia drug. It contains a propafenone(1+).

Фармакокине?тика

Propafenone hydrochloride (Rythmol(R)) is similar in action to flecainide. It reduces the fast inward sodium current in Purkinje fibres and to a lesser extent in myocardial fibres. Unlike other class l drugs, propafenone has mild B-blocking effects. This may contribute to its overall effects on the conduction system. lt is also believed to have calcium channel-blocking effects, which may contribute to its mild negative inotropic effects.
