What Is Sotalol?

Sotalol medication for dogs is a prescription oral heart drug used in dogs, cats and horses to treat abnormally rapid or dangerous heart rhythms (arrhythmias) which may be due to the presence of heart disease.

It is usually prescribed by veterinarians with the diagnosis of the type of arrhythmia-atrial fibrillation (affecting the upper chambers) or ventricular tachycardia (affecting the lower chambers) and the underlying cause.

Treatment aims at normalizing the heart rhythm and enhancing overall cardiac performance by making the heart rhythm more normal and stable.

This is an antiarrhythmic drug that is a Class III with a beta-blocker action, i.e. it acts in several ways. It reduces the rate of electrical conduction in the heart, increases the refractory period and prevents the movement of potassium within heart cells and also diminishes heart response to stress hormones such as adrenaline.

All these effects contribute to decreasing the heart rate, normalizing the rhythm, and mitigating the danger of severe cardiac events, enabling the heart to pump the blood more effectively and supply oxygen to the whole body.

Sotalol is administered either alone but can be combined with other heart drugs to provide more effective control of arrhythmias. It is FDA-approved to be used in people under various names such as Betapace® and Sotylize® but it is not specifically approved to be used in animals.

Rather, veterinarians do prescribe it as an extra-label (off-label) drug which is a normal and legal procedure when treating animals. Since off-label use can be different than labeling, it is important to take the advice of your veterinarian.

A veterinarian can prescribe a compound form of sotalol dosage in other cases, particularly when a pet cannot swallow standard tablets, where a particular dose level is required, or sensitivity to a particular ingredient.

These are tailor-made formulations that are made by licensed pharmacists or veterinarians according to specific needs, but not approved by the FDA. Veterinary advice should be followed properly and medication monitored and taken correctly to ensure successful and safe treatment.

How Sotalol Dosage Works in Dogs

Sotalol dose for dogs is a dual-action heart medication that functions as both a Class III antiarrhythmic (potassium channel blocker) and a beta-blocker, they assist in managing life threatening heart rhythm issues in dogs.

It stabilizes the heart electrical activity, helps slow down or stop abnormal or rapid heartbeats and is common in veterinary cardiology.

The major mechanisms of action of sotalol:

• Closes potassium channels in the heart, increasing the electrical reset time (refractory period) to stop abnormal rhythms occurring again.
• Normalizes heart rhythm by enhancing the flow of electrical signals in the heart.
• Reduces the effect of stress hormones such as adrenaline by slowing down heart rate by its beta-blocker effect.
• Enhances the efficiency of the heart as a whole, which enables the blood to circulate better.

Veterinary use:

• Off-label common in dogs and cats which is a normal and legal veterinary practice.
• Believed to work well with the irregular or fast heart beats (arrhythmias)
• Particularly useful in conditions such as arrhythmogenic right ventricular cardiomyopathy (ARVC) especially in Boxer dogs.

Possible Side Effects & Risks of Sotalol in Dogs

In dogs, sotalol dosage for dogs may trigger various side effects, mild or severe, therefore, close attention should be paid to the treatment. Most dogs will not react to the drug but some might develop an apparent change in energy, appetite or heart rate.

Some of the common side effects are:

• Fatigue (low energy) and loss of energy.
• Weakness and loss of balance.
• Reduced appetite
• Vomiting, nausea and occasionally diarrhea.

Serious risks and cardiovascular:

• Slow heart rate (bradycardia)
• Fainting, collapse or dizziness.
• Having trouble breathing or coughing.
• Exacerbation of the heart failure (use with caution)
• Serious but rare abnormal rhythm (torsades de pointes)

Immediately you should call your veterinarian:

• Severe lethargy, weakness or collapse.
• Very slow pulse or fainting.
• Difficulty breathing, coughing.
• Weakness, dizziness (signs of low blood pressure).
• Symptoms of worsening heart failure (fatigue, more difficult breathing)

Risk factors – NOT to be used in a dog that:

• Are allergic to sotalol
• Suffers asthma, heart block or has a slow heart rate to begin with.
• Have uncontrolled congestive heart failure or in shock.

Should be used with care in dogs which:

• Has controlled congestive heart failure.
• Have diabetes, kidney disease or hyperthyroidism.
• Pregnant/lactating.

In the case that there are any strange symptoms, they should consult with the veterinary as soon as possible. The effects of this short-acting drug are usually short lived (less than 24 hours) but can last longer in dogs with liver or kidney diseases.

Dosage & Administration Guidelines for Sotalol Dosage for Dogs

Sotalol dosage administration to dogs should be done under medical guidance as it is a strong cardiac drug that is administered to regulate irregular heartbeats. Safety and effectiveness require proper timing, consistency and following instructions.

Dosage guidelines:

• Possibly: in certain emergency situations: may begin at 1-1.5 mg/kg TID (three times a day), then can be changed to twice day (BID).
• Common tablet strengths: 80 mg, 120 mg, 160 mg, and 240 mg

Administration instructions:

• Normally administered on a 12 hour basis to maintain a regular heart rate.
• To be taken on an empty stomach (at least 1 hour before or 2 hours after meals) in order to be best absorbed.
• May be administered along with a light snack in case of stomach upsets.

Important safety guidelines:

• Do not come to an abrupt halt–tapering gradually under the supervision of a veterinarian is needed to prevent dangerous arrhythmias.
• Do not change the dose without the doctors.
• In case of a missed dose, take it as soon as possible, but omit it when within a 24-hour time span of the next dose – never take two doses.

Drug Interactions & Contraindications of Sotalol in Dogs

Sotalol drug for dogs is capable of interacting with many drugs and therefore, it is important to tell your veterinarian all the drugs, supplements or herbal products your dog is on before starting treatment. These periods may predispose to low heart rate (bradycardia), low blood pressure (hypotension) or irregular heartbeats.

There are common drug interactions which include:

• Other antiarrhythmics (e.g. mexiletine, amiodarone, lidocaine) and digoxin
• Calcium channel blockers and clonidine.
• Antacids
• Some antibiotics like azithromycin, clarithromycin and erythromycin and fluoroquinolones.
• NSAIDs, fluoxetine and diuretics.
• Tricyclic antidepressants, phenothiazines, cyclobenzaprine and sympathomimetics.
• Cisapride and methimazole
• Phenylpropanolamine (not recommended)
• Insulin (should be closely monitored in diabetic pets)

Sotalol medication can also have an influence on the level of sugar and it can disrupt glucose or insulin tolerance test.

Contraindications and precautions:

• Not to be used in dogs with severe uncontrolled heart failure, asthma, a great deal of heart block or very slow heart rate (except when a pacemaker is implanted)
• Should be used with care in dogs that have kidney disease because it might need to be altered.

Special care and veterinary attention are essential in order to prevent severe adverse effects of drug interactions or underlying diseases.
