WARNING: ASTHMA-RELATED DEATH

Long-acting beta2-adrenergic agonists (LABA) increase the risk of asthma-related death. Data from a large placebo-controlled US study that compared the safety of another long-acting beta2-adrenergic agonist (salmeterol) or placebo added to usual asthma therapy showed an increase in asthma-related deaths in patients receiving salmeterol. This finding with salmeterol is considered a class effect of LABA, including formoterol, the active ingredient in Oxis Turbuhaler Inhalation Solution. The safety and efficacy of Oxis Turbuhaler in patients with asthma have not been established. All LABA, including Oxis Turbuhaler, are contraindicated in patients with asthma without use of a long-term asthma control medication .

4 CONTRAINDICATIONS

All LABA, including Oxis Turbuhaler, are contraindicated in patients with asthma without use of a long-term asthma control medication. .

  • All LABA, including Oxis Turbuhaler, are contraindicated in patients with asthma without use of a long-term asthma control medication. (4)

5 WARNINGS AND PRECAUTIONS

  • Do not initiate Oxis Turbuhaler Inhalation Solution in acutely deteriorating patients.
  • Do not use for relief of acute symptoms. Concomitant short-acting beta2-agonists can be used as needed for acute relief. (5.2)
  • Do not exceed the recommended dose. Excessive use of Oxis Turbuhaler Inhalation Solution, or use in conjunction with other medications containing long-acting beta2-agonists, can result in clinically significant cardiovascular effects, and may be fatal. (5.3, 5.5)
  • Life-threatening paradoxical bronchospasm can occur. Discontinue Oxis Turbuhaler Inhalation Solution immediately. (5.4)
  • Use with caution in patients with cardiovascular or convulsive disorders, thyrotoxicosis, or with sensitivity to sympathomimetic drugs. (5.6, 5.7)

5.1 Asthma-Related Deaths


Data from a large placebo-controlled study in asthma patients showed that long-acting beta2-adrenergic agonists may increase the risk of asthma-related death. Data are not available to determine whether the rate of death in patients with COPD is increased by long-acting beta2-adrenergic agonists.

A 28-week, placebo-controlled US study comparing the safety of salmeterol with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in patients receiving salmeterol (13/13,176 in patients treated with salmeterol vs. 3/13,179 in patients treated with placebo; RR 4.37, 95% CI 1.25, 15.34). The increased risk of asthma-related death is considered a class effect of the long-acting beta2-adrenergic agonists, including Oxis Turbuhaler Inhalation Solution. No study adequate to determine whether the rate of asthma related death is increased in patients treated with Oxis Turbuhaler Inhalation Solution has been conducted. The safety and efficacy of Oxis Turbuhaler in patients with asthma have not been established. All LABA, including Oxis Turbuhaler, are contraindicated in patients with asthma without use of a long-term asthma control medication. .

Clinical studies with formoterol fumarate administered as a dry powder inhaler suggested a higher incidence of serious asthma exacerbations in patients who received formoterol than in those who received placebo. The sizes of these studies were not adequate to precisely quantify the differences in serious asthma exacerbation rates between treatment groups.

5.2 Deterioration of Disease and Acute Episodes

Oxis Turbuhaler Inhalation Solution should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition. Oxis Turbuhaler Inhalation Solution has not been studied in patients with acutely deteriorating COPD. The use of Oxis Turbuhaler Inhalation Solution in this setting is inappropriate.

Oxis Turbuhaler Inhalation Solution should not be used for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. Oxis Turbuhaler Inhalation Solution has not been studied in the relief of acute symptoms and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled short-acting beta2-agonist.

When beginning Oxis Turbuhaler Inhalation Solution, patients who have been taking inhaled, short-acting beta2-agonists on a regular basis should be instructed to discontinue the regular use of these drugs and use them only for symptomatic relief of acute respiratory symptoms. When prescribing Oxis Turbuhaler Inhalation Solution, the healthcare provider should also prescribe an inhaled, short-acting beta2-agonist and instruct the patient how it should be used. Increasing inhaled beta2-agonist use is a signal of deteriorating disease for which prompt medical attention is indicated. COPD may deteriorate acutely over a period of hours or chronically over several days or longer. If Oxis Turbuhaler Inhalation Solution no longer controls the symptoms of bronchoconstriction, or the patient’s inhaled, short-acting beta2-agonist becomes less effective or the patient needs more inhalation of short-acting beta2-agonist than usual, these may be markers of deterioration of disease. In this setting, a re-evaluation of the patient and the COPD treatment regimen should be undertaken at once. Increasing the daily dosage of Oxis Turbuhaler Inhalation Solution beyond the recommended 20 mcg twice daily dose is not appropriate in this situation.

5.3 Excessive Use and Use with Other Long-Acting Beta2-Agonists

As with other inhaled beta2-adrenergic drugs, Oxis Turbuhaler Inhalation Solution should not be used more often, at higher doses than recommended, or in conjunction with other medications containing long-acting beta2-agonists, as an overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs.

5.4 Paradoxical Bronchospasm

As with other inhaled beta2-agonists, Oxis Turbuhaler Inhalation Solution can produce paradoxical bronchospasm that may be life-threatening. If paradoxical bronchospasm occurs, Oxis Turbuhaler Inhalation Solution should be discontinued immediately and alternative therapy instituted.

5.5 Cardiovascular Effects

Oxis Turbuhaler Inhalation Solution, like other beta2-agonists, can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic and/or diastolic blood pressure, and/or symptoms. If such effects occur, Oxis Turbuhaler Inhalation Solution may need to be discontinued. In addition, beta-agonists have been reported to produce ECG changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression. The clinical significance of these findings is unknown. Therefore, Oxis Turbuhaler Inhalation Solution, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

5.6 Coexisting Conditions

Oxis Turbuhaler Inhalation Solution, like other sympathomimetic amines, should be used with caution in patients with convulsive disorders or thyrotoxicosis, and in patients who are unusually responsive to sympathomimetic amines. Doses of the related beta2-agonist albuterol, when administered intravenously, have been reported to aggravate preexisting diabetes mellitus and ketoacidosis.

5.7 Hypokalemia and Hyperglycemia

Beta-agonist medications may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to produce adverse cardiovascular effects . The decrease in serum potassium is usually transient, not requiring supplementation. Beta-agonist medications may produce transient hyperglycemia in some patients.

Clinically significant changes in serum potassium and blood glucose were infrequent during clinical studies with long-term administration of Oxis Turbuhaler Inhalation Solution at the recommended dose.

5.8 Immediate Hypersensitivity Reactions

Immediate hypersensitivity reactions may occur after administration of Oxis Turbuhaler Inhalation Solution, as demonstrated by cases of anaphylactic reactions, urticaria, angioedema, rash, and bronchospasm.

6 ADVERSE REACTIONS

Long acting beta2-adrenergic agonists such as formoterol increase the risk of asthma-related death .

Most common adverse reactions (>2% and more common than placebo) are diarrhea, nausea, nasopharyngitis, dry mouth, vomiting, dizziness, and insomnia (6.2)


To report SUSPECTED ADVERSE REACTIONS, contact Mylan Specialty L.P. at 1-800-429-7751 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1 Beta2-Agonist Adverse Reaction Profile

Adverse reactions to Oxis Turbuhaler Inhalation Solution are expected to be similar in nature to other beta2-adrenergic receptor agonists including: angina, hypertension or hypotension, tachycardia, arrhythmias, nervousness, headache, tremor, dry mouth, muscle cramps, palpitations, nausea, dizziness, fatigue, malaise, insomnia, hypokalemia, hyperglycemia, and metabolic acidosis.

6.2 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.

Adults with COPD

The data described below reflect exposure to Oxis Turbuhaler Inhalation Solution 20 mcg twice daily by oral inhalation in 586 patients, including 232 exposed for 6 months and 155 exposed for at least 1 year. Oxis Turbuhaler Inhalation Solution was studied in a 12-week, placebo- and active-controlled trial and a 52-week, active-controlled trial (463 subjects treated with Oxis Turbuhaler Inhalation Solution). Patients were mostly Caucasians (88%) between 40-90 years old (mean, 64 years old) and had COPD, with a mean FEV1 of 1.33 L. Patients with significant concurrent cardiac and other medical diseases were excluded from the trials.

Table 1 shows adverse reactions from the 12-week, double-blind, placebo-controlled trial where the frequency was greater than or equal to 2% in the Oxis Turbuhaler Inhalation Solution group and where the rate in the Oxis Turbuhaler Inhalation Solution group exceeded the rate in the placebo group. In this trial, the frequency of patients experiencing cardiovascular adverse events was 4.1% for Oxis Turbuhaler Inhalation Solution and 4.4% for placebo. There were no frequently occurring specific cardiovascular adverse events for Oxis Turbuhaler Inhalation Solution (frequency greater than or equal to 1% and greater than placebo). The rate of COPD exacerbations was 4.1% for Oxis Turbuhaler Inhalation Solution and 7.9% for placebo.

Patients treated with Oxis Turbuhaler Inhalation Solution 20 mcg twice daily in the 52-week open-label trial did not experience an increase in specific clinically significant adverse events above the number expected based on the medical condition and age of the patients.

6.3 Postmarketing Experience

The following adverse reactions have been reported during post-approval use of Oxis Turbuhaler Inhalation Solution. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Anaphylactic reactions, urticaria, angioedema (presenting as face, lip, tongue, eye, pharyngeal, or mouth edema), rash, and bronchospasm

7 DRUG INTERACTIONS

  • Other adrenergic drugs may potentiate effect. Use with caution.
  • Xanthine derivatives, steroids, diuretics, or non-potassium sparing diuretics may potentiate hypokalemia or ECG changes. Use with caution. (5.7, 7.2, 7.3)
  • MAO inhibitors, tricyclic antidepressants and drugs that prolong QTc interval may potentiate effect on the cardiovascular system. Use with extreme caution. (7.4)
  • Beta-blockers may decrease effectiveness. Use with caution and only when medically necessary. (7.5)

7.1 Adrenergic Drugs

If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of formoterol may be potentiated .

7.2 Xanthine Derivatives, Steroids, or Diuretics

Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of adrenergic agonists .

7.3 Non-potassium Sparing Diuretics

The ECG changes and/or hypokalemia that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of beta-agonists with non-potassium sparing diuretics.

7.4 MAO Inhibitors, Tricyclic Antidepressants, QTc Prolonging Drugs

Formoterol, as with other beta2-agonists, should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, or drugs known to prolong the QTc interval because the effect of adrenergic agonists on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval have an increased risk of ventricular arrhythmias.

7.5 Beta-blockers

Beta-adrenergic receptor antagonists (beta-blockers) and formoterol may inhibit the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta-agonists, but may produce severe bronchospasm in COPD patients. Therefore, patients with COPD should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-blockers in patients with COPD. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Teratogenic Effects: Pregnancy Category C

Formoterol fumarate administered throughout organogenesis did not cause malformations in rats or rabbits following oral administration. However, formoterol fumarate was found to be teratogenic in rats and rabbits in other testing laboratories. When given to rats throughout organogenesis, oral doses of 0.2 mg/kg and above delayed ossification of the fetus, and doses of 6 mg/kg (approximately 1200 times the maximum recommended daily inhalation dose in humans on a mg/m2 basis) and above decreased fetal weight. Formoterol fumarate has been shown to cause stillbirth and neonatal mortality at oral doses of 6 mg/kg and above in rats receiving the drug during the late stage of pregnancy. These effects, however, were not produced at a dose of 0.2 mg/kg. Because there are no adequate and well-controlled studies in pregnant women, Oxis Turbuhaler Inhalation Solution should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Women should be advised to contact their physician if they become pregnant while taking Oxis Turbuhaler Inhalation Solution.

8.2 Labor and Delivery

There are no adequate and well-controlled human studies that have investigated the effects of Oxis Turbuhaler Inhalation Solution during labor and delivery.

Because beta-agonists may potentially interfere with uterine contractility, Oxis Turbuhaler Inhalation Solution should be used during labor only if the potential benefit justifies the potential risk.

8.3 Nursing Mothers

In reproductive studies in rats, formoterol was excreted in the milk. It is not known whether formoterol is excreted in human milk, but because many drugs are excreted in human milk, caution should be exercised if Oxis Turbuhaler Inhalation Solution is administered to nursing women. There are no well-controlled human studies of the use of Oxis Turbuhaler Inhalation Solution in nursing mothers.

Women should be advised to contact their physician if they are nursing while taking Oxis Turbuhaler Inhalation Solution.

8.4 Pediatric Use

Oxis Turbuhaler Inhalation Solution is not indicated for use in children. The safety and effectiveness of Oxis Turbuhaler Inhalation Solution in pediatric patients have not been established. The pharmacokinetics of formoterol fumarate has not been studied in pediatric patients.

8.5 Geriatric Use

Of the 586 subjects who received Oxis Turbuhaler Inhalation Solution in clinical studies, 284 were 65 years and over, while 89 were 75 years and over. Of the 123 subjects who received Oxis Turbuhaler Inhalation Solution in the 12-week safety and efficacy trial, 48 (39%) were 65 years of age or older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger adult patients, but greater sensitivity of some older individuals cannot be ruled out.

The pharmacokinetics of Oxis Turbuhaler Inhalation Solution has not been studied in elderly subjects.

10 OVERDOSAGE

The expected signs and symptoms with overdosage of Oxis Turbuhaler Inhalation Solution are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the signs and symptoms listed under ADVERSE REACTIONS. Signs and symptoms may include angina, hypertension or hypotension, tachycardia with rates up to 200 beats/min, arrhythmias, nervousness, headache, tremor, seizures, muscle cramps, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, hyperglycemia, hypokalemia, and metabolic acidosis. As with all inhaled sympathomimetic medications, cardiac arrest and even death may be associated with an overdose of Oxis Turbuhaler Inhalation Solution.

Treatment of overdosage consists of discontinuation of Oxis Turbuhaler Inhalation Solution together with institution of appropriate symptomatic and/or supportive therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of Oxis Turbuhaler Inhalation Solution. Cardiac monitoring is recommended in cases of overdosage.

The minimum lethal inhalation dose of formoterol fumarate in rats is 156 mg/kg (approximately 32,000 times the maximum recommended daily inhalation dose in humans on a mg/m2 basis). The median lethal oral doses in Chinese hamsters, rats, and mice provide even higher multiples of the maximum recommended daily inhalation dose in humans.

For additional information about overdose treatment, call a poison control center (1-800-222-1222).

11 DESCRIPTION

Oxis Turbuhaler (formoterol fumarate) Inhalation Solution is supplied as 2 mL of formoterol fumarate inhalation solution packaged in a 2.5 mL single-use low-density polyethylene vial and overwrapped in a foil pouch. Each vial contains 2 mL of a clear, colorless solution composed of Oxis Turbuhaler, USP equivalent to 20 mcg of formoterol fumarate in an isotonic, sterile aqueous solution containing sodium chloride, pH adjusted to 5.0 with citric acid and sodium citrate.

The active component of Oxis Turbuhaler Inhalation Solution is Oxis Turbuhaler, USP, a racemate. Oxis Turbuhaler is a beta2-adrenergic bronchodilator. Its chemical name is (±)-2-hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1-methylethyl]-amino]ethyl]formanilide fumarate dihydrate; its structural formula is:

Figure 2 Mean* FEV1 at Endpoint after 12 Weeks of Treatment

  • * Figures show least-squares means adjusted for baseline FEV1

Patients treated with Oxis Turbuhaler Inhalation Solution used less rescue albuterol during the trial compared to patients treated with placebo.

Examination of age (≥ 65 or younger) and gender subgroups did not identify differences in response to Oxis Turbuhaler Inhalation Solution. There were too few non-Caucasian subjects to assess differences in populations defined by race adequately.

In the 12 week study, 78% of subjects achieved a 15% increase from baseline FEV1 following the first dose of Oxis Turbuhaler Inhalation Solution 20 mcg. In these subjects, the median time to onset of bronchodilation, defined as 15% increase in FEV1, was 11.7 minutes. When defined as an increase in FEV1 of 12% and 200 mL, the time to onset of bronchodilation was 13.1 minutes after dosing. The median time to peak bronchodilator effect was 2 hours after dosing.

17 PATIENT COUNSELING INFORMATION

Asthma-Related Death

Patients should be informed that long acting beta agonist, such as Oxis Turbuhaler, increase the risk of asthma-related death. All LABA, including Oxis Turbuhaler, should not be used in patients with asthma without use of a long-term asthma control medication.

Acute Exacerbations or Deteriorations

Oxis Turbuhaler Inhalation Solution is not indicated for relief of acute symptoms, and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled, short-acting beta2-agonist (the healthcare provider should provide the patient with such medication and instruct the patient in how it should be used). Patients should be instructed to seek medical attention if their symptoms worsen despite recommended doses of Oxis Turbuhaler Inhalation Solution, if Oxis Turbuhaler Inhalation Solution treatment becomes less effective, or if they need more inhalations of a short-acting beta2-agonist than usual.

Appropriate Dosing

Patients should not stop using Oxis Turbuhaler Inhalation Solution unless told to do so by a healthcare provider because symptoms may get worse. Patients should not inhale more than the prescribed number of vials at any one time. The daily dosage of Oxis Turbuhaler Inhalation Solution should not exceed one vial twice daily (40 mcg total daily dose). Excessive use of sympathomimetics may cause significant cardiovascular effects, and may be fatal.

Concomitant Therapy

Patients who have been taking inhaled, short-acting beta2-agonists (e.g., albuterol) on a regular basis should be instructed to discontinue the regular use of these products and use them only for symptomatic relief of acute symptoms. Oxis Turbuhaler Inhalation Solution should not be used in conjunction with other inhaled medications containing long-acting beta2-agonists. Patients should be warned not to stop or change the dose of other concomitant COPD therapy without medical advice, even if symptoms improve after initiating treatment with Oxis Turbuhaler Inhalation Solution.

Common Adverse Reactions with Beta2-agonists

Patients should be informed that treatment with beta2-agonists may lead to adverse reactions that include palpitations, chest pain, rapid heart rate, increased or decreased blood pressure, headache, tremor, nervousness, dry mouth, muscle cramps, nausea, dizziness, fatigue, malaise, low blood potassium, high blood sugar, high blood acid, or trouble sleeping .

Instructions for Administration

It is important that patients understand how to use Oxis Turbuhaler Inhalation Solution with a nebulizer appropriately . Patients should be instructed not to mix other medications with Oxis Turbuhaler Inhalation Solution or ingest Oxis Turbuhaler Inhalation Solution. Patients should throw the plastic dispensing container away immediately after use. Due to their small size, the container and top pose a danger of choking to young children.
