Items in AFP with MESH term: Bronchodilator Agents
ABSTRACT: Boxed warnings, commonly referred to as 'black box' warnings, are issued by the U.S. Food and Drug Administration and featured in the labeling of drugs associated with serious adverse reactions. These safety concerns are typically identified through the Adverse Event Reporting System and the Office of Surveillance and Epidemiology, which evaluates postmarket safety findings. The most common type of warning is issued when there is a potentially serious adverse effect that must be carefully weighed against the potential benefit of the drug. Warnings are also issued to draw attention to dosing, monitoring requirements, and potential drug interactions. Boxed warnings have been issued recently for oral sodium phosphate bowel preparations, fluoroquinolone antibiotics, and salmeterol. Despite these highly publicized warnings, all of these medications remain viable treatment options with appropriate patient selection. Ultimately, physicians must decide whether to prescribe drugs with boxed warnings.
Management of COPD Exacerbations - Article
ABSTRACT: Exacerbations of chronic obstructive pulmonary disease contribute to the high mortality rate associated with the disease. Randomized controlled trials have demonstrated the effectiveness of multiple interventions. The first step in outpatient management should be to increase the dosage of inhaled short-acting bronchodilators. Combining ipratropium and albuterol is beneficial in relieving dyspnea. Oral corticosteroids are likely beneficial, especially for patients with purulent sputum. The use of antibiotics reduces the risk of treatment failure and mortality in moderately or severely ill patients. Physicians should consider antibiotics for patients with purulent sputum and for patients who have inadequate symptom relief with bronchodilators and corticosteroids. The choice of antibiotic should be guided by local resistance patterns and the patient's recent history of antibiotic use. Hospitalized patients with exacerbations should receive regular doses of short-acting bronchodilators, continuous supplemental oxygen, antibiotics, and systemic corticosteroids. Noninvasive positive pressure ventilation or invasive mechanical ventilation is indicated in patients with worsening acidosis or hypoxemia.
Acute Bronchitis - Article
ABSTRACT: Acute bronchitis is a lower respiratory tract infection that causes reversible bronchial inflammation. In up to 95 percent of cases, the cause, is viral. While antibiotics are often prescribed for patients with acute bronchitis, little evidence shows that these agents provide significant symptomatic relief or shorten the course of the illness. In a few small studies, bronchodilators such as albuterol have been found to relieve some symptoms of acute bronchitis. Increased attention is being given to the role of Chlamydia species in acute bronchitis and adult-onset asthma. Studies in progress may help to clarify the importance of these organisms in acute bronchitis and to determine whether early treatment can prevent or ameliorate asthma.
Effectiveness of Bronchodilators for Bronchiolitis Treatment - Cochrane for Clinicians
ABSTRACT: Patients with suspected food allergies are commonly seen in clinical practice. Although up to 15 percent of parents believe their children have food allergies, these allergies have been confirmed in only 1 to 3 percent of all Americans. Family physicians must be able to separate true food allergies from food intolerance, food dislikes, and other conditions that mimic food allergy. The most common foods that produce allergic symptoms are milk, eggs, seafood, peanuts, and tree nuts. Although skin testing and in vitro serum immunoglobulin E assays may help in the evaluation of suspected food allergies, they should not be performed unless the clinical history suggests a specific food allergen to which testing can be targeted. Furthermore, these tests do not confirm food allergy. Confirmation requires a positive food challenge or a clear history of an allergic reaction to a food and resolution of symptoms after eliminating that food from the diet. More than 70 percent of children will outgrow milk and egg allergies by early adolescence, whereas peanut allergies usually remain throughout life. The most serious allergic response to food allergy is anaphylaxis. It requires emergency care that should be initiated by the patient or family using an epinephrine autoinjector, which should be carried by anyone with a diagnosed food allergy. These and other recommendations presented in this article are derived from the Guidelines for the Diagnosis and Management of Food Allergy in the United States, published by the National Institute of Allergy and Infectious Diseases.
