Identifiers on file: NDC 71335-1189, application ANDA207428, label effective 20260611. It is one of 12 FDA drug label records sharing the active ingredient SOTALOL HYDROCHLORIDE. This page reproduces the FDA-approved label text so you can check what a product is, who makes it and how it is supplied before discussing it with a pharmacist or prescriber.

Across FDA labelling, products containing SOTALOL HYDROCHLORIDE are most often described in connection with: sotalol hydrochloride, ventricular arrhythmias, antiarrhythmic indicated, treatment life, premature contraction, life-threatening documented, tachycardia limitation, enhance survival. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1. INDICATIONS AND USAGE Sotalol Hydrochloride Tablets are an antiarrhythmic indicated for: the treatment of life threatening ventricular arrhythmias ( 1.1 ) Limitations of Use Avoid use in patients with asymptomatic ventricular premature contraction ( 1.1 ) 1.1 Life-Threatening Ventricular Arrhythmias Sotalol Hydrochloride Tablets are indicated for the treatment of life-threatening, documented ventricular arrhythmias, such as sustained ventricular tachycardia (VT). Limitation of Use: Sotalol Hydrochloride Tablets may not enhance survival in patients with ventricular arrhythmias. Because of the proarrhythmic effects of Sotalol Hydrochloride Tablets, including a 1.5 to 2% rate of Torsade de Pointes (TdP) or new ventricular tachycardia/fibrillation (VT/VF) in patients with either non-sustained ventricular tachycardia (NSVT) or supraventricular arrhythmias (SVT), its use in patients with less severe arrhythmias, even if the patients are symptomatic, is generally not recommended. Avoid treatment of patients with asymptomatic ventricular premature contractions [ see Warnings and Precautions (5.2) .]

2 DOSAGE AND ADMINISTRATION Sotalol Hydrochloride Tablets: Initial dosage in adults is 80 mg twice daily. Increase the dose as needed in increments of 80 mg/day, every 3 days to a maximum 320 mg total daily dose ( 2.2 ) Pediatrics: Dosage depends on age ( 2.4 ) 2.1 General Safety Measures for Initiation of Oral Sotalol Therapy Withdraw other antiarrhythmic therapy before starting Sotalol Hydrochloride Tablets and monitor carefully for a minimum of 2 to 3 plasma half-lives if the patient's clinical condition permits [ see Drug Interactions (7) ]. Hospitalize patients initiated or re-initiated on sotalol for at least 3 days or until steady-state drug levels are achieved, in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring. Initiate oral sotalol therapy in the presence of personnel trained in the management of serious arrhythmias. Perform a baseline ECG to determine the QT interval and measure and normalize serum potassium and magnesium levels before initiating therapy. Measure serum creatinine and calculate an estimated creatinine clearance in order to establish the appropriate dosing interval (insert cross ref to renal dosing). Continually monitor patients with each uptitration in dose, until they reach steady state. Determine QT c 2 to 4 hours after every dose. Discharge patients on sotalol therapy from an in-patient setting with an adequate supply of sotalol to allow uninterrupted therapy until the patient can fill a sotalol prescription. Advise patients who miss a dose to take the next dose at the usual time. Do not double the dose or shorten the dosing interval. 2.2 Adult Dose for Ventricular Arrhythmias The recommended initial dose is 80 mg twice daily. This dose may be increased in increments of 80 mg per day every 3 days provided the QT c <500 msec [ see Warnings and Precautions (5.1) ]. Continually monitor patients until steady state blood levels are achieved. In most patients, a therapeutic response is obtained at a total daily dose of 160 to 320 mg/day, given in two or three divided doses (because of the long terminal elimination half- life of sotalol, dosing more than a two times a day is usually not necessary). Oral doses as high as 480-640 mg/day have been utilized in patients with refractory life-threatening arrhythmias. 2.4 Pediatric Dose for Ventricular Arrhythmias Use the same precautionary measures for children as you would use for adults when initiating and re-initiating sotalol treatment. For children aged about 2 years and older For children aged about 2 years and older, with normal renal function, doses normalized for body surface area are appropriate for both initial and incremental dosing. Since the Class III potency in children is not very different from that in adults, reaching plasma concentrations that occur within the adult dose range is an appropriate guide [ see Clinical Pharmacology (12.1 , 12.3 )] . From pediatric pharmacokinetic data the following is recommended: For initiation of treatment, 30 mg/m 2 three times a day (90 mg/m2 total daily dose) is approximately equivalent to the initial 160 mg total daily dose for adults. Subsequent titration to a maximum of 60 mg/m 2 (approximately equivalent to the 360 mg total daily dose for adults) can then occur. Titration should be guided by clinical response, heart rate and QT c , with increased dosing being preferably carried out in-hospital. At least 36 hours should be allowed between dose increments to attain steady-state plasma concentrations of sotalol in patients with age-adjusted normal renal function. For children aged about 2 years or younger For children aged about 2 years or younger, the above pediatric dosage should be reduced by a factor that depends heavily upon age, as shown in the following graph, age plotted on a logarithmic scale in months. For a child aged 20 months, the dosing suggested for children with normal renal function aged 2 years or greater should be multiplied by about 0.97; the initial starting dose would be (30 X 0.97)=29.1 mg/m 2 , administered three times daily. For a child aged 1 month, the starting dose should be multiplied by 0.68; the initial starting dose would be (30 X 0.68)=20 mg/m 2 , administered three times daily. For a child aged about 1 week, the initial starting dose should be multiplied by 0.3; the starting dose would be (30 X 0.3)=9 mg/m 2 . Use similar calculations for dose titration. Since the half-life of sotalol decreases with decreasing age (below about 2 years), time to steady-state will also increase. Thus, in neonates the time to steady-state may be as long as a week or longer. 2.5 Dosage for Patients with Renal Impairment Adults Use of sotalol in any age group with decreased renal function should be at lower doses or increased intervals between doses. It will take much longer to reach steady-state with any dose and/or frequency of administration. Closely monitor heart rate and QT c . Dose escalations in renal impairment should be done after administration of at least 5 doses at appropriate intervals (Table 1). Sotalol is partly removed by dialysis; specific advice is unavailable on dosing patients on dialysis. The initial dose of 80 mg and subsequent doses should be administered at the intervals listed in Table 1. Table 1: Dosing Intervals for treatment of Ventricular Arrhythmias in renal impairment Creatinine Clearance mL/min Dosing Interval (hours) > 60 12 30–59 24 10–29 36–48 < 10 Dose should be individualized 2.6 Preparation of Extemporaneous Oral Solution Sotalol Hydrochloride Syrup 5 mg/mL can be compounded using Simple Syrup containing 0.1% sodium benzoate (Syrup, NF) as follows: Measure 120 mL of Simple Syrup. Transfer the syrup to a 6-ounce amber plastic (polyethylene terephthalate [PET]) prescription bottle. An oversized bottle is used to allow for a headspace, so that there will be more effective mixing during shaking of the bottle. Add five (5) Sotalol Hydrochloride 120 mg tablets to the bottle. These tablets are added intact; it is not necessary to crush the tablets. The addition of the tablets can also be done first. The tablets can also be crushed if preferred. If the tablets are crushed, care should be taken to transfer the entire quantity of tablet powder into the bottle containing the syrup. Shake the bottle to wet the entire surface of the tablets. If the tablets have been crushed, shake the bottle until the endpoint is achieved. Allow the tablets to hydrate for at least two hours. After at least two hours have elapsed, shake the bottle intermittently over the course of at least another two hours until the tablets are completely disintegrated. The tablets can be allowed to hydrate overnight to simplify the disintegration process. The endpoint is achieved when a dispersion of fine particles in the syrup is obtained. This compounding procedure results in a solution containing 5 mg/mL of sotalol HCl. The fine solid particles are the water-insoluble inactive ingredients of the tablets. Stability studies indicate that the suspension is stable for three months when stored at 15°C to 30°C (59°F to 86°F) [see USP Controlled Room Temperature] and ambient humidity.

6 ADVERSE REACTIONS The most common adverse reactions (≥2%) for Sotalol Hydrochloride Tablets are: fatigue 4%, bradycardia (less than 50 bpm) 3%, dyspnea 3%, proarrhythmia 3%, asthenia 2%, and dizziness 2%. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Beximco Pharmaceuticals USA Inc. at 877-372-6093 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse reactions that are clearly related to sotalol are those which are typical of its Class II (beta-blocking) and Class III (cardiac action potential duration prolongation) effects and are dose related. Ventricular Arrhythmias Serious Adverse Reactions In patients with a history of sustained ventricular tachycardia, the incidence of Torsade de Pointes during oral sotalol treatment was 4% and worsened VT was about 1%; in patients with other less serious ventricular arrhythmias the incidence of Torsade de Pointes was 1% and new or worsened VT was about 0.7%. Incidence of Torsade de Pointes arrhythmias in patients with VT/VF are shown in Table 3 below. Table 3: Percent Incidence of Torsade de Pointes and Mean QTc Interval by Dose For Patients With Sustained VT/VF Daily Dose (mg) Torsade de Pointes Incidence Mean QTc highest on-therapy value (msec) 80 0 (69) 463 (17) 160 0.5 (832) 467 (181) 320 1.6 (835) 473 (344) 480 4.4 (459) 483 (234) 640 3.7 (324) 490 (185) >640 5.8 (103) 512 (62) ( ) Number of patients assessed Table 4 below relates the incidence of Torsade de Pointes to on-therapy QT c and change in QT c from baseline in patients with ventricular arrhythmias. It should be noted, however, that the highest on-therapy QT c was in many cases the one obtained at the time of the Torsade de Pointes event, so that the table overstates the predictive value of a high QT c . Table 4: Relationship Between QTc Interval Prolongations and Torsade de Pointes On-Therapy QT c Interval (msec) Incidence of Torsade de Pointes Change from Baseline in QT c (msec) Incidence of Torsade de Pointes <500 1.3% (1787) <65 1.6% (1516) 500-525 3.4% (236) 65-80 3.2% (158) 525-550 5.6% (125) 80-100 4.1% (146) >550 10.8% (157) 100-130 5.2% (115) >130 7.1% (99) ( ) Number of patients assessed Table 5: Incidence (%) of Common Adverse Reactions (2% in the Placebo group and less frequent than Sotalol Hydrochloride Tablets groups) in a Placebo-controlled Parallel-group Comparison Study of Patients with Ventricular Ectopy Body System/Adverse Reaction (Preferred Term) Placebo Sotalol Hydrochloride Total Daily Dose N=37 (%) 320 mg N=38 (%) 640 mg N=39 (%) CARDIOVASCULAR Chest Pain 5.4 7.9 15.4 Dyspnea 2.7 18.4 20.5 Palpitation 2.7 7.9 5.4 Vasodilation 2.7 0.0 5.1 NERVOUS SYSTEM Asthenia 8.1 10.5 20.5 Dizziness 5.4 13.2 17.9 Fatigue 10.8 26.3 25.6 Headache 5.4 5.3 7.7 Lightheaded 8.1 15.8 5.1 Sleep Problem 2.7 2.6 7.7 RESPIRATORY Upper Respiratory Tract Problem 2.7 2.6 12.8 SPECIAL SENSES Visual Problem 2.7 5.3 0.0 The most common adverse reactions leading to discontinuation of Sotalol Hydrochloride Tablets in trials of patients with ventricular arrhythmias are: fatigue 4%, bradycardia (less than 50 bpm) 3%, dyspnea 3%, proarrhythmia 3%, asthenia 2%, and dizziness 2%. Incidence of discontinuation for these adverse reactions was dose related. One case of peripheral neuropathy that resolved on discontinuation of Sotalol Hydrochloride Tablets and recurred when the patient was rechallenged with the drug was reported in an early dose tolerance study. Pediatric Patients In an unblinded multicenter trial of 25 pediatric patients with SVT and/or VT receiving daily doses of 30, 90 and 210 mg/m 2 with dosing every 8 ours for a total of 9 doses, no Torsade de Pointes or other serious new arrhythmias were observed. One (1) patient, receiving 30 mg/m 2 daily, was discontinued because of increased frequency of sinus pauses/bradycardia. Additional cardiovascular AEs were seen at the 90 and 210 mg/m 2 daily dose levels. They included QT prolongation (2 patients), sinus pauses/bradycardia (1 patient), increased severity of atrial flutter and reported chest pain (1 patient). Values for QT c 525 msec were seen in 2 patients at the 210 mg/m 2 daily dose level. Serious adverse events including death, Torsade de Pointes, other proarrhythmias, high-degree A-V blocks, and bradycardia have been reported in infants and/or children.
