Children may benefit from asthma prophylaxis using sodium cromoglicate or nedocromil sodium. 

Sodium cromoglicate is used for prophylaxis in asthma when there appears to be an allergic basis to the condition. Although its mechanism of action is not well understood, it appears to reduce the release of inflammatory agents from mast cells and so is useful in asthma prophylaxis, particularly in children. It is unlikely to be of value in COPD.

W ithin the past few years a number of new drugs have been introduced to treat respiratory disorders, such as bronchial asthma and disorders that produce chronic airway obstruction. This chapter discusses the bronchodilators, dragp that have been around for a long time but are still effective in specific instances, and the newer antiasthma drugs that have proven to be highly effective in the prophylaxis (prevention) of breathing difficulty. 

Zafirlukast and zileuton are used in the prophylaxis and treatment of chronic asthma in adults and children older than 12 years. Montelukast is used in the prophylaxis and treatment of chronic asthma in adults and in children older than 2 years.

Patients receiving these agents may notice improvement in 1 to 2 weeks, but maximal benefit may not be seen for 4 to 6 weeks. Cromolyn and nedocromil appear to be similar in efficacy to the leukotriene antagonists and theophylline for persistent asthma.18 Both agents are well tolerated with adverse effects limited to cough and wheezing. Bad taste and headache have also been reported with nedocromil. One dose of cromolyn or nedocromil prior to exercise or allergen exposure will provide effective prophylaxis for 1 to 2 hours. Cromolyn and nedocromil are not as effective as albuterol for prophylaxis of exercise-induced asthma. 

In patients with mild intermittent asthma, long-term control medications are not necessary, and patients should use a short-acting inhaled P2-agonist t° prevent or treat symptoms.2 This classification includes patients with exercise-induced asthma, seasonal asthma, or asthma symptoms associated with infrequent trigger exposure. Patients can pre-treat with two puffs of cromolyn or nedocromil prior to exposure to a known trigger. The treatment of choice for exercise-induced asthma is two inhalations of albuterol 5 minutes prior to exercise.1 Cromolyn and nedocromil are less effective than albuterol for prophylaxis of exercise-induced asthma. 

Anti-lice alcoholic preparations are considered more effective than aqueous preparations. However, alcoholic preparations are unsuitable for use in children and patients with asthma and eczema. Anti-lice preparations should not be used for prophylaxis because they are ineffective and may encourage the development of resistance. 

Zafirlukast is a leukotriene-receptor antagonist. Leukotriene-receptor antagonists are used for prophylaxis of asthma and should not be used to relieve an attack of acute severe asthma. 

Acetazolamide is a carbonic anhydrase inhibitor that reduces aqueous humour production and is therefore indicated in glaucoma to reduce the intraocular pressure. Salbutamol is a selective, short-acting beta2-agonist used as a bronchodilator in asthma. Tolbutamide is a short-acting sulphonylurea used in type 2 (non-insulin dependent) diabetes mellitus. Chlorpromazine is an aliphatic neuroleptic antipsychotic drug used in schizophrenia. Zafirlukast is a leukotriene-receptor antagonist that is indicated in the prophylaxis of asthma but should not be used to relieve acute severe asthma. 

Q53 Before initiating treatment with omalizumab, body weight and immunoglobulin E concentration need to be determined. Omalizumab is a monoclonal antibody administered by subcutaneous injection for the prophylaxis of allergic asthma. 

Beclometasone is a corticosteroid. Corticosteroids are used as prophylaxis in patients with asthma and therefore have no use in an acute attack. Bronchodilators acting as relievers are indicated for an acute attack. In asthma, patients are advised first to administer the bronchodilator, which acts very fast and then apply the corticosteroid, which has anti-inflammatory properties. 

Stabilization of mast cells. Cromolyn prevents IgE-mediated release of mediators, although only after chronic treatment. Moreover, by interfering with the actions of mediator substances on inflammatory cells, it causes a more general inhibition of allergic inflammation. It is applied locally to conjunctiva, nasal mucosa, bronchial tree (inhalation), intestinal mucosa (absorption almost nil with oral intake). Indications prophylaxis of hay fever, allergic asthma, and food allergies. 

Bitolterol Prophylaxis and treatment of bronchial asthma and reversible bronchospasm. May be used with or without concurrent theophylline or steroid therapy.
