Sotalol Canon
Sotalol Canon Uses, Dosage, Side Effects, Food Interaction and all others data.
Sotalol Canon is a non-cardioselective beta-blocker. It increases sinus cycle length, slows heart rate, decreases AV nodal conduction and increases AV nodal refractoriness. It also prolongs AV monophasic action potentials. However, it lacks intrinsic sympathomimetic and membrane-stabilising properties.
Sotalol Canon is a competitive inhibitor of the rapid potassium channel. This inhibition lengthens the duration of action potentials and the refractory period in the atria and ventricles. The inhibition of rapid potassium channels is increases as heart rate decreases, which is why adverse effects like torsades de points is more likely to be seen at lower heart rates. L-sotalol also has beta adrenergic receptor blocking activity seen above plasma concentrations of 800ng/L. The beta blocking ability of sotalol further prolongs action potentials. D-sotalol does not have beta blocking activity but also reduces a patient's heart rate while standing or exercising. These actions combine to produce a negative inotropic effect that reduces the strength of contractility of muscle cells in the heart. Extension of the QT interval is also adversely associated with the induction of arrhythmia in patients.
Hyperglycemia is a greater risk for non insulin dependant diabetics than insulin dependant diabetics. Beta blockers inhibit insulin secretion which may cause hyperglycemia in type II diabetes mellitus. The risk of hypoglycemia is higher in insulin dependant diabetes than non insulin dependant diabetics. Beta blockers decrease secretion of insulin, which may mask hypoglycemia in an insulin dependant patient. Beta blockers also increase glucose uptake into cells which may prolong or potentiate hypoglycemia.

Uses
Arrhythmias, Cardiac arrhythmias, Supraventricular and ventricular arrhythmias
Sotalol Canon is also used to associated treatment for these conditions: Atrial Fibrillation, Flutter, Atrial, Severe ventricular arrhythmias
How Sotalol Canon works
Sotalol Canon inhibits beta-1 adrenoceptors in the myocardium as well as rapid potassium channels to slow repolarization, lengthen the QT interval, and slow and shorten conduction of action potentials through the atria. The action of sotalol on beta adrenergic receptors lengthens the sinus node cycle, conduction time through the atrioventricular node, refractory period, and duration of action potentials.
Dosage
Sotalol Canon dosage
Oral (Adult)-
Supraventricular and ventricular arrhythmias: Initial: 80 mg/day in 1 -2 divided doses, increase gradually every 2-3 days. Usual: 160-320 mg/day in 2 divided doses. Max: 640 mg/day.
Life-threatening ventricular arrhythmias: 480-640 mg/day.
Acute arrhythmias: 20-120 mg, may repeat 6 hrly if needed.
For programmed electrical stimulation (to test antiarrhythmic efficacy): Initial: 1.5 mg/kg, then 0.2-0.5 mg/kg/hr infusion
Side Effects
Dyspnea, Dizziness, Fatigue, Bradycardia, Chest pain, Palpitation, Weakness, Lightheadedness, Nausea/vomiting, Edema, Headache, Sleep disturbances, Abnormal ECG, Diarrhea, Extremity pain, Hypotension, Mental confusion, Congestive heart failure, ltching/rash, Syncope, Anxiety, Depression, Torsades de pointes or new ventricular tachycardia / fibrillation in patients with supraventricular arrhythmia, Peripheral vascular disorders, Impotence, Proarrhythmic effect, Torsades de pointes with history of sustained ventricular tachycardia, Catechol hypersensitivity after abrupt withdrawal, Increased insulin requirement in diabetics
Toxicity
Patients experiencing an overdose may present with bradycardia, congestive heart failure, hypotension, bronchospasm, and hypoglycemia. Larger intentional overdoses may present as hypotension, bradycardia, cardiac asystole, prolonged QT interval, torsade de pointes, ventricular tachycardia, and premature ventricular complexes. Stop administering sotalol and observe the patient until the QT interval returns to normal and the heart rate rises above 50 beats per minute. Hemodialysis may help lower plasma concentrations of sotalol as it is not bound to plasma proteins. Bradycardia and cardiac asystole may be treated with atropine, other anticholinergic drugs, beta adrenergic agonists, or transvenous cardiac pacing.. Second or third degree heart block may be treated with a transvenous cardiac pacemaker. Hypotension may be treated with epinephrine or norepinephrine. Bronchospasm may be treated with aminophylline or a beta-2 agonist, possibly at higher than normal doses. Torsade de pointes may be treated with DC cardioversion, transvenous cardiac pacing, epinephrine, or magnesium sulfate.
The oral LD50 for rats is 3450mg/kg, intraperitoneal LD50 for rats is 680mg/kg, oral LD50 for mice is 2600mg/kg, and intraperitoneal LD50 for mice is 670mg/kg.
Pregnant rabbits given 6 times the maximum recommended human dose showed an increase in fetal death and maternal toxicity, while rats given 18 times the maximum recommended human dose had an increased number of fetal resorptions. Sotalol Canon is present in human breast milk so patients taking sotalol should not breast feed.
Sotalol Canon has not been found to be carcinogenic. No studies have been performed regarding mutagenicity or clastogenicity. In animal studies, sotalol was not associated with a reduction in fertility aside from smaller litter sizes.

Sotalol Canon Alcohol interaction
[Moderate]
Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation.
Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.
Caution and close monitoring for development of hypotension is advised during coadministration of these agents.
Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs.
Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
Sotalol Canon Cholesterol interaction
[Moderate] Beta-adrenergic receptor blocking agents (aka beta-blockers) may alter serum lipid profiles.
Increases in serum VLDL and LDL cholesterol and triglycerides, as well as decreases in HDL cholesterol, have been reported with some beta-blockers.
Patients with preexisting hyperlipidemia may require closer monitoring during beta-blocker therapy, and adjustments made accordingly in their lipid-lowering regimen.
Sotalol Canon multivitamins interaction
[Moderate] ADJUST DOSING INTERVAL: Concurrent administration with calcium salts may decrease the oral bioavailability of atenolol and possibly other beta-blockers.
The exact mechanism of interaction is unknown.
In six healthy subjects, calcium 500 mg (as lactate, carbonate, and gluconate) reduced the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of atenolol (100 mg) by 51% and 32%, respectively.
The elimination half-life increased by 44%.
Twelve hours after the combination, beta-blocking activity (as indicated by inhibition of exercise tachycardia) was reduced compared to that with atenolol alone.
However, during a 4-week treatment in six hypertensive patients, there was no difference in blood pressure values between treatments.
The investigators suggest that prolongation of the elimination half-life induced by calcium coadministration may have led to atenolol cumulation during long-term dosing, which compensated for the reduced bioavailability.
It may help to separate the administration times of beta-blockers and calcium products by at least 2 hours.
Patients should be monitored for potentially diminished beta-blocking effects following the addition of calcium therapy.
