What is Dilanyl?

Dilanyl injection is used to prevent bronchospasm in patients 12 years of age and older with asthma, bronchitis, emphysema, and other lung diseases.

Dilanyl belongs to the family of medicines known as bronchodilators. Bronchodilators are medicines that relax the muscles in the bronchial tubes (air passages) of the lungs. They relieve cough, wheezing, shortness of breath, and troubled breathing by increasing the flow of air through the bronchial tubes.

Dilanyl is available only with your doctor's prescription.

Uses of Dilanyl in details

Use: Labeled Indications

Asthma/Bronchospasm: Prevention and reversal of bronchospasm in patients ≥12 years of age with asthma and reversible bronchospasm associated with bronchitis and emphysema

Off Label Uses

Extravasation management, sympathomimetic vasoconstrictors

Data from a limited number of patients suggests that Dilanyl may be beneficial for the management of extravasation of sympathomimetic vasoconstrictors.

Dilanyl description

Dilanyl turbuhaler is a breath-activated, multiple-dose powder inhaler free from propellant, lubricant, preservative, carrier substances or other additives.

Dilanyl injection also contains the following inactive ingredients: Sodium chloride, HCl (for pH adjustment) and water for injections.

Dilanyl sulphate is 2-(tert-butylamino)-1-(3,5-dihydroxyphenyl)ethanol sulphate.

Dilanyl dosage

Tablet: Adults: Usual Dose: 1-2 tablets. Children 12-15 years: 1 tablet. All doses to be taken 2-3 times daily.

To be administered at approximately 6-hr intervals. In most patients, the optimum single dose is 2 tablets. In patients unusually sensitive to sympathomimetic amines, initiate treatment with 1 tablet 3 times a day. If adequate bronchodilation is not obtained, the dose may be increased to 2 tablets.

Syrup: Adults and Children >15 years: 10-15 mL (2-3 tsp). Children 7-15 years: 5-10 mL (1-2 tsp); 3-7 years: 2.5-5 mL (½-1 tsp); <3 years: Not recommended. All doses to be taken 3 times a day.

Nebulizing Solution: Dilanyl nebulizing solution is used with dilution.

Inhale 1 mL of solution containing Dilanyl sulfate 2.5 mg every 6 hrs (or 4 times in 24-hr period).

If the entire dose is not inhaled at 1 occasion, the solution is stable for 24 hrs in the reservoir of the nebulizer.

Note: The patient's inhalation technique should be checked regularly and the optimal dose of Dilanyl should be adjusted for each nebulizer. If the effect of the inhalation is reduced, the patient should seek medical care.

Nonselective blocking agents may partly or totally inhibit the effect of β-stimulants.

Directions for Use: 1. Pipette 1 mL of Dilanyl nebulizing solution from the bottle by using a calibrated medicine dropper provided in the pack, equivalent to Dilanyl sulfate 2.5 mg.

2. Drop the solution into an electric nebulizer and dilute it with normal saline solution 2 mL and start inhalation.

3. Repeat the same procedure every 6 hrs or 4 times in 24-hr period.

Dilanyl interactions

What other drugs will affect Dilanyl?

Drug Interactions

The concomitant use of Dilanyl with other sympathomimetic agents is not recommended, since the combined effect on the cardiovascular system may be deleterious to the patient

Monoamine Oxidase Inhibitors or Tricyclic Antidepressants: Dilanyl should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, since the action of Dilanyl on the vascular system may be potentiated

Beta-Blockers Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as Dilanyl, but may produce severe bronchospasm in asthmatic patients. Therefore, patients with asthma 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-adrenergic blocking agents in patients with asthma. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution

Diuretics The ECG changes and/or hypokalemia that may result from the administration of nonpotassium-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 coadministration of beta-agonists with nonpotassium-sparing diuretics.
