Indications & Usage
1 INDICATIONS & USAGE Montelukast sodium tablets are a leukotriene receptor antagonist indicated for: Prophylaxis and chronic treatment of asthma in patients 15 years of age and older ( 1.1 ).

Acute prevention of exercise-induced bronchoconstriction (EIB) in patients 15 years of age and older ( 1.2 ).

Relief of symptoms of allergic rhinitis (AR): seasonal allergic rhinitis (SAR) in patients 15 years of age and older, and perennial allergic rhinitis (PAR) in patients 15 years of age and older.

Reserve use for patients who have an inadequate response or intolerance to alternative therapies ( 1.3 ).

Limitations of Use: Not indicated to treat an acute asthma attack ( 5.2 ).

1.1 Asthma Montelukast sodium tablets are indicated for the prophylaxis and chronic treatment of asthma in patients 15 years of age and older.

1.2 Exercise-Induced Bronchoconstriction (EIB) Montelukast sodium tablets are indicated for prevention of exercise-induced bronchoconstriction (EIB) in patients 15 years of age and older.

1.3 Allergic Rhinitis Montelukast sodium is indicated for the relief of symptoms of seasonal allergic rhinitis in patients 15 years of age and older and perennial allergic rhinitis in patients 15 years of age and older.

Because the benefits of montelukast sodium tablets may not outweigh the risk of neuropsychiatric symptoms in patients with allergic rhinitis [see Warnings and Precautions ( 5.1 )], reserve use for patients who have an inadequate response or intolerance to alternative therapies.

1.4 Limitations of Use Montelukast sodium is not indicated for the treatment of an acute asthma attack.
Adverse Reactions
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Neuropsychiatric Events [see Warnings and Precautions ( 5.1 )] Most common adverse reactions (incidence ≥ 5% and greater than placebo listed in descending order of frequency): upper respiratory infection, fever, headache, pharyngitis, cough, abdominal pain, diarrhea, otitis media, influenza, rhinorrhea, sinusitis, otitis ( 6.1 ).

To report SUSPECTED ADVERSE REACTIONS, contact Macleods Pharma USA, Inc., at 1-888-943-3210 or 1-855-926-3384 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 clinical practice.

In the following description of clinical trials experience, adverse reactions are listed regardless of causality assessment.

The most common adverse reactions (incidence ≥5% and greater than placebo; listed in descending order of frequency) in controlled clinical trials were: upper respiratory infection, fever, headache, pharyngitis, cough, abdominal pain, diarrhea, otitis media, influenza, rhinorrhea, sinusitis, otitis.

Adults and Adolescents 15 Years of Age and Older with Asthma Montelukast sodium has been evaluated for safety in approximately 2950 adult and adolescent patients 15 years of age and older in clinical trials.

In placebo-controlled clinical trials, the following adverse reactions reported with montelukast occurred in greater than or equal to 1% of patients and at an incidence greater than that in patients treated with placebo: Table 5: Adverse Reactions Occurring in ≥1% of Patients with an Incidence Greater than that in Patients Treated with Placebo Montelukast 10 mg/day (%) (n=1955) Placebo (%) (n=1180) Body As A Whole Pain, abdominal 2.9 2.5 Asthenia/fatigue 1.8 1.2 Fever 1.5 0.9 Trauma 1.0 0.8 Digestive System Disorders Dyspepsia 2.1 1.1 Pain, dental 1.7 1.0 Gastroenteritis, infectious 1.5 0.5 Nervous System/Psychiatric Headache 18.4 18.1 Dizziness 1.9 1.4 Respiratory System Disorders Influenza 4.2 3.9 Cough 2.7 2.4 Congestion, nasal 1.6 1.3 Skin/Skin Appendages Disorder Rash 1.6 1.2 Laboratory Adverse Reactions Number of patients tested (montelukast sodium and placebo, respectively): ALT and AST, 1935, 1170; pyuria, 1924, 1159.

ALT increased 2.1 2.0 AST increased 1.6 1.2 Pyuria 1.0 0.9 The frequency of less common adverse reactions was comparable between montelukast sodium and placebo.

The safety profile of montelukast sodium, when administered as a single dose for prevention of EIB in adult and adolescent patients 15 years of age and older, was consistent with the safety profile previously described for montelukast sodium.

Cumulatively, 569 patients were treated with montelukast sodium for at least 6 months, 480 for one year, and 49 for two years in clinical trials.

With prolonged treatment, the adverse reaction profile did not significantly change.

Adults and Adolescents 15 Years of Age and Older with Seasonal Allergic Rhinitis Montelukast sodium has been evaluated for safety in 2199 adult and adolescent patients 15 years of age and older in clinical trials.

Montelukast sodium administered once daily in the morning or in the evening had a safety profile similar to that of placebo.

In placebo-controlled clinical trials, the following reaction was reported with montelukast sodium with a frequency ≥ 1% and at an incidence greater than placebo: upper respiratory infection, 1.9% of patients receiving montelukast sodium vs.

1.5% of patients receiving placebo.

In a 4-week, placebo-controlled clinical study, the safety profile was consistent with that observed in 2-week studies.

The incidence of somnolence was similar to that of placebo in all studies.

Adults and Adolescents 15 Years of Age and Older with Perennial Allergic Rhinitis Montelukast sodium has been evaluated for safety in 3357 adult and adolescent patients 15 years of age and older with perennial allergic rhinitis of whom 1632 received montelukast sodium in two, 6-week, clinical studies.

Montelukast sodium administered once daily had a safety profile consistent with that observed in patients with seasonal allergic rhinitis and similar to that of placebo.

In these two studies, the following reactions were reported with montelukast sodium with a frequency ≥ 1% and at an incidence greater than placebo: sinusitis, upper respiratory infection, sinus headache, cough, epistaxis, and increased ALT.

The incidence of somnolence was similar to that of placebo.

6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of montelukast sodium.

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.

Blood and lymphatic system disorders increased bleeding tendency, thrombocytopenia.

Immune system disorders hypersensitivity reactions including anaphylaxis, hepatic eosinophilic infiltration.

Psychiatric disorders including, but not limited to, agitation, aggressive behavior or hostility, anxiousness, depression, disorientation, disturbance in attention, dream abnormalities, dysphemia (stuttering), hallucinations, insomnia, irritability, memory impairment, obsessive-compulsive symptoms, restlessness, somnambulism, suicidal thinking and behavior (including suicide), tic, and tremor [see Boxed Warning, Warnings and Precautions ( 5.1 )] Nervous system disorders drowsiness, paraesthesia/hypoesthesia, seizures.

Cardiac disorders: palpitations Respiratory, thoracic and mediastinal disorders : epistaxis, pulmonary eosinophilia Gastrointestinal disorders diarrhea, dyspepsia, nausea, pancreatitis, vomiting Hepatobiliary disorders Cases of cholestatic hepatitis, hepatocellular liver-injury, and mixed-pattern liver injury have been reported in patients treated with montelukast sodium.

Most of these occurred in combination with other confounding factors, such as use of other medications, or when montelukast sodium was administered to patients who had underlying potential for liver disease such as alcohol use or other forms of hepatitis.

Skin and subcutaneous tissue disorders angioedema, bruising, erythema multiforme, erythema nodosum, pruritus, Stevens-Johnson syndrome/toxic epidermal necrolysis, urticaria.

Musculoskeletal and connective tissue disorders arthralgia, myalgia including muscle cramps.

Renal and urinary disorders enuresis in children.

General disorders and administration site conditions edema.

Patients with asthma on therapy with montelukast sodium may present with systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition which is often treated with systemic corticosteroid therapy.

These reactions have been sometimes associated with the reduction of oral corticosteroid therapy.

Physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients [see Warnings and Precautions ( 5.5 )].
