Sotalol compositions and uses of the same
The present invention provides oral solutions containing sotalol hydrochloride which advantageously avoid swallowing while providing with improved stability. The present invention also relates to methods of using the oral solutions for treatment of diseases and disorders, such as delay in reoccurrence of atrial fibrillation/atrial flutter and/or ventricular arrhythmias.
1. A method of treating ventricular arrhythmia in a child in need thereof, comprising administering an oral solution comprising sotalol hydrochloride to the child,
wherein the oral solution is administered to the child in an initial dose of about 90 mg/m 2 per day.
2. The method of claim 1 , wherein the oral solution is administered to the child in a dose of about 30 mg/m 2 three times a day.
3. The method of claim 1 , further comprising a subsequent titration.
4. The method of claim 3 , wherein the titration is guided by clinical response, heart rate and QTc.
5. The method of claim 3 , wherein the initial dose is titrated to a maximum of 60 mg/m 2 three times a day.
6. The method of claim 3 , wherein at least 36 hours is allowed between dose increments to attain steady-state plasma concentrations of sotalol in the child with age-adjusted normal renal function.
7. The method of claim 1 , wherein the child is age 2 or older.
8. The method of claim 1 , wherein the child is younger than 2 years old.
9. A method of delaying recurrence of atrial fibrillation/atrial flutter in a patient in need thereof comprising administering an oral solution comprising sotalol hydrochloride,
wherein the oral solution is administered in a dose of up to 160 mg sotalol hydrochloride once or twice daily.
10. The method of claim 9 , wherein the oral solution is administered in a dose of up to 160 mg sotalol hydrochloride once daily.
11. A method of treating ventricular arrhythmia or delaying recurrence of atrial fibrillation/atrial flutter in a patient in need thereof, comprising administering an oral solution comprising sotalol hydrochloride,
wherein the oral solution is prepared by admixing sotalol hydrochloride and one or more excipients with water.
12. The method of claim 11 , wherein the oral solution is prepared by completely dissolving the sotalol hydrochloride and optionally the excipients, in a solution.
13. The method of claim 11 , wherein the oral solution consists of sotalol hydrochloride, water, citric acid, sodium citrate, sucralose, sodium benzoate and optionally a flavoring agent.
14. The method of claim 11 , wherein the oral solution is substantially free of polymers.
15. The method of claim 11 , wherein the oral solution is stable for greater than about 4 months.
