About classes I and II antiarrhythmic medication (and digoxin)?
Hi, two to three quick questions about class I and II's. Thanks
s I works on Na channel. What's a good example?
Class II are like beta blockers eg. metoprolol, propranolol. What channels do they work on?
Class III work on K channels eg. sotalol, amiodarone
Class IV are calcium channel blockers eg. diltiazem, verapamil.
Beta blockers block the norepinephrine & epinephrine from reacting with the receptors in the heart, simply.
Digoxin isn't in a class, it is miscellaneous because it is a cardiac glycoside.

Anti-arrhythmic drugs feat to control disturbances of the heart's rhythm.
* Amiodarone is very effective but it has side effects including headache, flushing, dizziness, and stomach upsets.
opafenone is used to treat intermittent or raging atrial fibrillation where the heart beats fast and irregularly and may lea to heart downfall. Its use is usually avoided in patients with asthma or chronic lung disease.
* Digoxin is used to treat atrial fibrillation. The drug slows the heart, relieving the symptoms of breathlessness and palpitation, but does not restore its regularity- additional treatment may be needed for this.
Beta blockers-- Lower blood pressure by decreasing the amount of blood pumped by the heart and by lowering the heart rate.
Beta-blockers control the speed and force of heart beat by blocking the action of harmons such as adrenaline that make the heart beat faster and more tirelessly. They are effective in preventing angina. They can also lower raised blood pressure, lessen the risk of further heart attacks and help control abnormal heart rhythms.
dness or fatigue may also be experienced.
