Action ⬆ ⬇

Inhaln: Inhibits cholinergic receptors in bronchial smooth muscle, resulting in decreased concentrations of cyclic guanosine monophosphate (cGMP). Decreased levels of cGMP produce local bronchodilation.
Local application inhibits secretions from glands lining the nasal mucosa.

Therapeutic effects:

Inhaln: Bronchodilation without systemic anticholinergic effects.
Decreased rhinorrhea.

Classifications ⬆ ⬇

Therapeutic Classification: allergy, cold and cough remedies, bronchodilators

Pharmacologic Classification: anticholinergics

Pharmacokinetics ⬆ ⬇

Absorption: Minimal systemic absorption (2% for inhalation solution; 20% for inhalation aerosol; <20% following nasal use).

Distribution: 15% of dose reaches lower airways after inhalation.

Metabolism/Excretion: Small amounts absorbed are metabolized by the liver.

Half-Life: 2 hr.

Patient/Family Teaching ⬆ ⬇

Explain purpose and side effects of medication to patient. Advise patient to read Patient Information before starting therapy. Instruct patient in proper use of inhaler, nebulizer, or nasal spray and to take medication as directed. Take missed doses as soon as remembered unless almost time for the next dose; space remaining doses evenly during day. Do not double doses.
Advise patient to notify health care provider of all Rx or OTC medications, vitamins, or herbal products being taken and to consult health care provider before taking other medications.
Advise patient that rinsing mouth after using inhaler, proper oral hygiene, and sugarless gum or candy may minimize dry mouth. Health care provider should be notified if stomatitis occurs or if dry mouth persists for >2 wk.
Inhalation: Caution patient not to exceed 12 doses within 24 hr. Patient should notify health care provider if symptoms do not improve within 30 min after administration of medication or if condition worsens.
- Explain need for pulmonary function tests before and periodically during therapy to determine effectiveness of medication.
- Caution patient to avoid spraying medication in eyes; may cause blurring of vision or irritation.
- Advise patient to inform health care provider if cough, nervousness, headache, dizziness, nausea, or GI distress occurs.
Nasal Spray: Instruct patient in proper use of nasal spray. Clear nasal passages gently before administration. Do not inhale during administration, so medication remains in nasal passages. Prime pump initially with 7 actuations. If used regularly, no further priming is needed. If not used in 24 hr, prime with 2 actuations. If not used for >7 days, prime with 7 actuations.
- Advise patient to contact health care provider if symptoms do not improve within 1–2 wk or if condition worsens.
- Advise patient if hypersensitivity reactions occur (anaphylaxis) to seek immediate medical assistance.
