Aerosol therapy can give immediate relief for bronchospasm. Drugs may also be given to loosen thick mucus in the bronchial tree. The major advantage of aerosal therapy is that it delivers the medications to their immediate site of action, thus reducing systemic adverse effects. To produce the same therapeutic action, an oral medication would have to be given at higher doses and would be distributed to all body tissues.

Nebulizers are small machine that vaporize a liquid drug into a fine mist that can be inhaled. often us ing a face-mask.

If the drug is a solid, it may be administered using a dry powder inhaler (DPl). A DPI is a small device that is activated by the process of inhalation to deliver a fine powder directly to the bronchial tree. Turbo halers and rota halers are types of DPis.

5

Metered-dose inhalers (MDls) are a third type of device commonly used to deliver respiratory medicines. MDis use a propellant to deliver a measured dose of drugs to the lungs during each breath. The patient times the inhalation to the puff of drug emitted from the MDI. Patients must be carefully instructed on the correct use of these devices because drug dose depends on their correct use. In add ition, swallowing medication that has been depoited in the oral cavity may cause the drug to be absorbed in the gatrointestinal (G I) tract, causing potential adverse effects

The primary goal of drug therapy for many respiratory disorders is to keep the airways open. Drugs include bronchodilators, which directly open the airways, and antiinflammatory drugs, which prevent their closure. Drugs may be used to act on excessive mucus blocking the airway., either by causing it to become thinner or by breaking up thick mucous plugs.

Regarding Inhaled Medications

When using MDis or DPis, allow an interval of at least 1 minute to pass between puffs.

When taking more than one respiratory medicine, take the bronchodilator first. This opens the airways and increases the effectiveness of the second medication.

Rinse the mouth thoroughly following inhaler use to reduce the oral absorption of inhaled medicines.

Take inhaled corticosteroids on a regular basis-not as needed. These medications are not used to stop acute asthma attacks.

Do not use decongestant nasal sprays for more than 2 or 3 days unless instructed to do so by a health care provider.

True

Regarding Bronchodilators

Avoid caffeine-containing foods and beverages if taking theophylline.

Immediately report any abnormalities in pulse rate, changes in blood pressure, or sensations of pa lpitations when taking beta-adrenergic stimulators.

True

12

Regarding Antihistamines and Decongestants

If taking antihistamines for the first time, avoid operating machinery or performing other tasks requiring alertness because drowsiness may occur.

Use hard candies, chewing gum, or ice chips to reduce the dry mouth caused by some decongestants and antihistamines.

Stop taking antihistamines and notify a health care provider if excessive sedation, wheezing, chest tightness, or bleeding/bruising occur.

Do not take OTC cold or allergy medicines containing antihistamines at the same time as prescription antihistamines.
