Prophylactic drugs in the management of childhood asthma.

Recurrences of explosive, severe asthma in children can often be prevented by immunotherapy and constant surveillance of environmental and dietary control. In addition, judicious and preserving use of pharmaceuticals may be employed for prophylaxis in childhood asthma. These include cromolyn sodium by inhalation, beclomethasone dipropionate aerosols, round-the-clock methylxanthines and beta 2 adrenergic bronchodilator agents. Their application is discussed.
