Chapter 37 bronchodilators and respiratory drugs

What is the most common side effect of decongestants sympathomimetic amines? An important distinction emerges regarding how these drugs are used in combination with other agents: What are the uses for acetylcysteine Mucomyst?

As noted, the use of oral theophyllines remains a third-line therapy in both the major obstructive lung diseases. Similarly, in COPD, many patients show responses to drugs on some occasions but not others.

Calverley, in Clinical Respiratory Medicine Fourth EditionUse of Bronchodilator Drugs in Clinical Practice The uses of bronchodilators in Chapter 37 bronchodilators and respiratory drugs diseases are considered elsewhere in this book.

Data on the use of bronchodilators in conditions such as bronchiectasis are much more limited, and although these drugs are widely prescribed in this context, their use is based largely on extrapolation from pharmacologic management of clinical entities such as asthma and COPD, for which much more information is available.

Accordingly, intravenous aminophylline is no longer recommended in patients who can use appropriate nebulized short-acting bronchodilator drugs. Evidence from metaanalysis of existing clinical trials shows no benefit in either setting from the use of aminophylline and is associated with a considerable risk of toxicity, especially when the patient has been receiving theophyllines as part of the regular medication regimen before intravenous therapy begins.

In general, the likelihood of a response falls as the baseline lung function worsens, along with the degree of clinical emphysemas. This information can be helpful as an adjunct to other diagnostic and clinical assessments but unfortunately cannot be relied on by itself as a guaranteed way of defining specific diseases.

Here the decision to add a combination inhaler is guided more by symptom severity and complications, as indicated in recent treatment guidelines. Glucocoritcoids, like fluticasone Flonase take weeks to take effect. Intravenous therapy is not appropriate with antimuscarinic drugs but has been widely used to deliver aminophylline for both asthma exacerbations and acute COPD for many years.

Mobilize mucus secretions in pulmonary infections, COPD 2. What are the 2 major changes to lungs with emphysema? In asthma, it is the within- and between-day variability in lung function that is more important than the acute response to a drug, although a return to normal lung function after a bronchodilator test on a day when lung function is impaired constitutes strong evidence for this diagnosis.

Tricyclic Antidepressants - increase effects Propanolol and Beta Blockers - excessive hypertension, decreased bronchodilation Methyldopa - decreased antihypertensive effect What is Rhinitis? They block the histamine already released from reaching the receptor sites When is the best time to administer loratidine Claritin Most effective given on an empty stomach 1 hr ac or 2 hrs pc What class is fluticasone Flonase, Flovent in?

The latter drug has the advantage that only 15 minutes is required before the patient can be retested, explaining its popularity in many laboratories. Aid to Diagnosis Bronchodilator reversibility testing is still widely performed in many laboratories. LABA treatment should not be used as monotherapy for this condition.
