How does dofetilide work?
Dofetilide belongs to a class of medications known as antiarrhythmic drugs specifically a class III antiarrhythmic agent. It works by blocking certain electrical channels in the heart, which helps to restore and maintain a normal heart rhythm.
The main way dofetilide works is by blocking certain potassium channels in the heart. These channels, known as rapid delayed rectifier potassium channels, play a crucial role in the repolarization of cardiac cells. By blocking these channels, dofetilide prolongs the action potential duration and refractory period of the heart.
By prolonging the action potential duration, dofetilide helps to restore a regular rhythm in the heart. It does this by preventing certain abnormal electrical signals or impulses from rapidly firing and causing chaotic rhythms. This allows the heart to beat in a more coordinated and regular manner.
Forms of dofetilide available
Dofetilide is available in the form of oral capsules.
Dosage of dofetilide
The dosage of dofetilide may vary depending on the individual’s condition, medical history, and response to the medication. It is important to follow the recommended dosage instructions provided by the healthcare provider.
Directions for dofetilide use
Dofetilide should be taken exactly as directed by the healthcare provider. The medication is usually taken orally, with or without food. It is important to take dofetilide consistently and continue the prescribed treatment course.
Warnings and precautions for dofetilide
- Dofetilide may cause certain side effects, including changes in heart rhythm, dizziness, and chest pain. It may also increase the risk of life-threatening ventricular arrhythmias. Close monitoring is necessary during treatment
- One of the major concerns with dofetilide is the risk of a type of abnormal heart rhythm called torsades de pointes. Certain medications can increase this risk when taken together with dofetilide
- If you have impaired renal function or your creatinine clearance falls below a certain threshold, taking dofetilide may be contraindicated. Additionally, if you have hypokalemia (low potassium levels), low magnesium levels or long QT syndrome, it is important to consult with your healthcare provider before starting dofetilide treatment. These pre-existing conditions can affect the safety and effectiveness of this medication in managing heart rhythm disorders
- It is important to inform your healthcare provider about all the medications you are taking, including prescription drugs, over-the-counter medications, and herbal supplements. They can evaluate the potential adverse effects and make necessary adjustments to your treatment plan to ensure the safety and effectiveness of the medications
Drug interactions with dofetilide
Some examples of medications that can interact with dofetilide include:
- Taking dofetilide with other cardiovascular or antiarrhythmic drugs such as digoxin, and verapamil can increase the risk of developing abnormal heart rhythms
- Cimetidine and trimethoprim-sulfamethoxazole can increase the levels of dofetilide in the blood, potentially leading to an increased risk of side effects
- Diuretic medications such as furosemide and hydrochlorothiazide can lower potassium levels in the body. Low potassium levels can increase the risk of developing abnormal heart rhythms when combined with dofetilide
- Macrolide antibiotics, such as erythromycin and clarithromycin, can interact with dofetilide and increase the risk of abnormal heart rhythms
- Antifungal medications, such as ketoconazole and itraconazole, can interact with dofetilide and increase the risk of abnormal heart rhythms
- Certain selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants can interact with dofetilide and increase the risk of abnormal heart rhythms
Use of dofetilide during pregnancy
The use of dofetilide during pregnancy should be carefully considered, and the potential risks and benefits should be discussed with a healthcare provider. The medication is generally not recommended during pregnancy unless the potential benefits outweigh the risks.
Use of dofetilide while breastfeeding
It is not known whether dofetilide passes into breast milk. The use of dofetilide while breastfeeding should be discussed with a healthcare provider, considering the potential risks and benefits for the mother and the infant.
Possible side effects of dofetilide
In clinical trials common side effects of dofetilide may include dizziness, headache, and abnormal taste sensations.
Serious side effects are possible but less common:
- Dofetilide can cause a lengthening of the QT interval, which is a measurement of the electrical activity in the heart. QTC (QT prolongation) can increase the risk of a dangerous heart rhythm called torsades de pointes, which can lead to fainting or even sudden cardiac arrest
- In some cases, dofetilide can trigger ventricular tachycardia, a rapid and potentially life-threatening heart rhythm originating from the lower chambers of the heart. This condition requires immediate medical attention
Similar drugs to dofetilide
Other antiarrhythmic medications used for the treatment of irregular heart rhythms include amiodarone, sotalol, and flecainide.
