Mast cell stabilizer; a pyranoquinoline dicarboxylic acid derivative.1 2 3 4 5 6 7 9 10 11 1 2 3 9 10 11

Uses for Tilade


Used as an adjunct in the overall management of mild to moderate bronchial asthma.1 2 3 4 5 9 10 11 a

For prophylaxis only; not indicated for reversal of acute bronchospasm, including status asthmaticus.a 1 9 10 (See Acute Bronchospasm under Warnings.)

Tilade Dosage and Administration


  • Initially, administer concurrently with patient’s existing maintenance dosages of β-adrenergic agonists, theophylline, and/or corticosteroids.a 1 2 4 5 Once clinical response is observed and asthma adequately controlled, gradual reduction in concomitant therapy may be possible.a 1 2 4 5


Oral Inhalation

Administer by oral inhalation using an oral aerosol inhaler.1

Shake inhaler well before use.1 8 Actuate aerosol inhaler 3 times prior to the initial use or if it has not been used for >7 days.a

Exhale slowly and completely, invert the inhaler, place the mouthpiece of the inhaler well into the mouth, and close the lips around it.8 Inhale slowly and deeply through the mouth while actuating the inhaler.8 Hold breath for 5–10 seconds, withdraw the mouthpiece, and exhale slowly.2 8

Avoid spraying in eyes.a

Clean inhaler twice weekly. Remove metal canister and cap and rinse plastic mouthpiece in hot running water. Allow to dry overnight in a warm place.a 8

Optimal therapeutic effect is dependent upon administration at regular intervals, even during symptom-free periods.a


Available as nedocromil sodium, dosage expressed in terms of the salt.a 1

The dose of nedocromil sodium is expressed as the amount delivered from the actuator of the inhaler per metered spray.a

Oral inhalation aerosol delivers 2 mg from the valve and 1.75 mg from the actuator per metered spray.a Each aerosol canister delivers ≥104 metered sprays.a 1

Pediatric Patients

Oral Inhalation

Children ≥6 years of age: 3.5 mg (2 inhalations) 4 times daily at regular intervals (14 mg/day).1

Less frequent administration may be effective if asthma is well controlled at this dose (e.g., patients only need occasional β-agonist therapy and are not experiencing serious exacerbations).a

Cautions for Tilade


Known hypersensitivity to nedocromil or any ingredient in the formulation.a



Acute Bronchospasm

Nedocromil is not a bronchodilator; do not use for reversal of acute bronchospasm, especially status asthmaticus.1 9 10 a

Use should generally be continued during acute exacerbations, unless patient becomes intolerant to use of inhaled dosage forms.a

Bronchospasm, possibly life-threatening, may occur immediately after administration.a If this occurs, discontinue nedocromil and institute alternative therapy.a

General Precautions

Concomitant Corticosteroid Dosage

Role of nedocromil as a corticosteroid-sparing agent in patients receiving oral or inhaled corticosteroids not defined.a Monitor patients closely if systemic or inhaled corticosteroids are reduced.a

Specific Populations

Common Adverse Effects

Unpleasant taste, coughing, pharyngitis, rhinitis, upper respiratory infection, dyspnea, bronchospasm, sinusitis, nausea, vomiting, headache, chest pain, fever, viral infection.a

Interactions for Tilade

No formal drug interaction studies to date.a

Tilade Pharmacokinetics



Absolute bioavailability is 8 and 17% for single and multiple inhaled doses, respectively.a


Full therapeutic effect may not be obtained for ≥1 week.a


Plasma Protein Binding



Elimination Route

Excreted principally in urine as unchanged drug.a


3.3 hours.a

Special Populations

Pharmacokinetics in children 6–11 years of age appear similar to those in adults.a



Oral Inhalation

Aerosol, Solution for Inhalation

2–30°C.a Do not freeze.a

Temperatures >120°F may cause aerosol canister to burst.a


  • Inhibits acute bronchoconstrictor response and delayed inflammatory response.a 1 2 6 9 10 11

  • In vitro, inhibits eosinophils, neutrophils, macrophages, mast cells, monocytes, platelets,a 1 2 3 9 10 11 histamine, leukotriene C4, and prostaglandin D2.a 1 2 3 5 6

  • Inhibits bronchoconstriction caused by sulfur dioxide, inhaled neurokinin A, various antigens, exercise, cold air, fog, and adenosine monophosphate.a

  • Exhibits no bronchodilator, antihistamine, or corticosteroid activity.a

  • Exhibits cough suppression resulting from inhibition of neuronal reflexes in airways.2 6 9 10

Advice to Patients

  • Importance of providing patient a copy of manufacturer’s patient information.a

  • Importance of adequate understanding of proper storage, preparation, disposal, and inhalation technique.a

  • Importance of adherence to dosing schedules, even during symptom-free periods, and of not changing dose unless otherwise instructed by a clinician.a

  • Importance of notifying physician immediately if symptoms do not improve or condition worsens.a

  • Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.a

  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs.a

  • Importance of informing patients of other important precautionary information.a (See Cautions.)
