Asthmatin 10
Rx

Montelukast is a selective leukotriene receptor antagonist with long duration of action. It inhibits the CysLT type-1 (CysLT1) receptor found in the human airway and on other pro-inflammatory cells. CysLTs have been correlated with the pathophysiology of asthma, including airway smooth muscle cells, airway edema and inflammatory process. CysLTs are released from the nasal mucosa after allergen exposure and are associated with symptoms of allergic rhinitis.

PRESCRIBING INFORMATION

Indications

  • For the prophylaxis and chronic treatment of asthma in adults and pediatric patients 12 months of age and older.
  • For prevention of exercise-induced bronchoconstriction (EIB) in patients 6 years of age and older.
  • For the relief of symptoms of seasonal allergic rhinitis in patients 2 years of age and older and perennial allergic rhinitis in patients 6 months of age and older.
  • Limitations of use: Asthmatin 10 is not indicated for the treatment of an acute asthma attack.

Dosage

  • Asthma
    Adult and adolescent patients 15 years of age and older: one 10 mg tablet.
    Pediatric patients 6 to 14 years of age: one 5 mg chewable tablet.
    Pediatric patients 2 to 5 years of age: one 4 mg chewable tablet or one packet of 4 mg oral granules.
    Pediatric patients 12 to 23 months of age: one packet of 4 mg oral granules.
    Safety and effectiveness in pediatric patients less than 12 months of age with asthma have not been established.
    Patients who miss a dose should take the next dose at their regular time and should not take 2 doses at the same time.
  • Exercise-induced bronchoconstriction (EIB)
    Adult and adolescent patients 15 years of age and older: one 10 mg tablet.
    Pediatric patients 6 to 14 years of age: one 5 mg chewable tablet.
    Safety and effectiveness in patients younger than 6 years of age have not been established.
    An additional dose of Asthmatin 10 should not be taken within 24 hours of a previous dose. Patients already taking Asthmatin 10 daily for another indication (including chronic asthma) should not take an additional dose to prevent EIB. All patients should have available for rescue a short-acting β-agonist.
    Daily administration of Asthmatin 10 for the chronic treatment of asthma has not been established to prevent acute episodes of EIB.
  • Allergic rhinitis
    Seasonal allergic rhinitis:
    + Adult and adolescent patients 15 years of age and older: one 10 mg tablet.
    + Pediatric patients 6 to 14 years of age: one 5 mg chewable tablet.
    + Pediatric patients 2 to 5 years of age: one 4 mg chewable tablet or one packet of 4 mg oral granules.
    Safety and effectiveness in pediatric patients younger than 2 years of age with seasonal allergic rhinitis have not been established.
    Perennial allergic rhinitis:
    + Adult and adolescent patients 15 years of age and older: one 10 mg tablet.
    + Pediatric patients 6 to 14 years of age: one 5 mg chewable tablet.
    + Pediatric patients 2 to 5 years of age: one 4 mg chewable tablet or one packet of 4 mg oral granules.
    + Pediatric patients 6 to 23 months of age: one packet of 4 mg oral granules.
    Safety and effectiveness in pediatric patients younger than 6 months of age with perennial allergic rhinitis have not been established.
    Patients who miss a dose should take the next dose at their regular time and should not take 2 doses at the same time.
    Using suitable dosage forms for each age is recommended.

Usage

Asthmatin 10 should be taken once daily.
For asthma, the dose should be taken in the evening.
For allergic rhinitis, the time of administration may be individualized to suit patient needs.
Patients with both asthma and allergic rhinitis should take only one tablet daily in the evening.
For prevention of EIB, administer a single dose of Asthmatin 10 orally at least 2 hours, before exercise.

Known hypersensitivity to any ingredient in the formulation.

Very common

  • Upper respiratory infection,
  • Hhypersensitivity reactions including anaphylaxis.

Common

  • Diarrhoea, nausea, vomiting;
  • Elevated levels of ALT, AST;
  • Rash;
  • Pyrexia.

Neuropsychiatric events

Serious neuropsychiatric (NP) events have been reported with use of Asthmatin 10. These postmarketing reports have been highly variable and included, but were 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 thoughts and behavior (including suicide), tic, and tremor.
NP events have been reported in adult, adolescent, and pediatric patients with and without a previous history of psychiatric disorder.
NP events have been reported mostly during Asthmatin 10 treatment, but some were reported after Asthmatin 10 discontinuation.
Because of the risk of NP events, the benefits of Asthmatin 10 may not outweigh the risks in some patients, particularly when the symptoms of disease may be mild and adequately treated with alternative therapies. Reserve use of Asthmatin 10 for patients with allergic rhinitis who have an inadequate response or intolerance to alternative therapies.
In patients with asthma or exercise-induced bronchoconstriction, consider the benefits and risks before prescribing Asthmatin 10.
Advise patients and/or caregivers to be alert for changes in behavior or for new NP symptoms when taking Asthmatin 10. If changes in behavior are observed, or if new NP symptoms or suicidal thoughts and/or behavior occur, advise patients to discontinue Asthmatin 10 and contact a healthcare provider immediately. In many cases, symptoms resolved after stopping Asthmatin 10 therapy; however, in some cases symptoms persisted after discontinuation of Asthmatin 10. Therefore, continue to monitor and provide supportive care until symptoms resolve. Re-evaluate the benefits and risks of restarting treatment with Asthmatin 10 if such events occur.

Acute asthma

Asthmatin 10 is not indicated for use in the reversal of bronchospasm in acute asthma attacks, including status asthmaticus. Patients should be advised to have appropriate rescue medication available. Therapy with Asthmatin 10 can be continued during acute exacerbations of asthma. Patients who have exacerbations of asthma after exercise should have available for rescue a short-acting inhaled β-agonist.

Concomitant corticosteroid use

While the dose of inhaled corticosteroid may be reduced gradually under medical supervision, Asthmatin 10 should not be abruptly substituted for inhaled or oral corticosteroids.

Aspirin sensitivity

Patients with known aspirin sensitivity should continue avoidance of aspirin or non-steroidal antiinflammatory agents while taking Asthmatin 10. Although Asthmatin 10 is effective in improving airway function in asthmatics with documented aspirin sensitivity, it has not been shown to truncate bronchoconstrictor response to aspirin and other non-steroidal anti-inflammatory drugs in aspirinsensitive asthmatic patients.

Eosinophilic conditions

Patients with asthma on therapy with Asthmatin 10 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 events 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. A causal association between Asthmatin 10 and these underlying conditions has not been established.

Excipient

Asthmatin 10 contains lactose. Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Use during pregnancy only when necessary.

Cautions should be exercised when taking the drug during lactation.

Montelukast is not expected to affect a patient’s ability to drive a car or operate machinery. However, in very rare cases, individuals have reported drowsiness or dizziness.
