Abstract

A method for converting pediatric patients from intravenous aminophylline to sustained-release oral theophylline was evaluated in eight asthmatic children. The administration of Theo-Dur tablets two hours before discontinuation of a continuous intravenous aminophylline infusion resulted in a peak rise of 5.6 +/- 3.0 micrograms/ml over steady-state serum theophylline concentrations. This method of conversion is acceptable in children with equivalent oral and intravenous doses of theophylline and serum theophylline concentrations less than 15 micrograms/ml. Children with steady-state theophylline concentrations greater than 15 micrograms/ml are likely to develop concentrations exceeding the therapeutic range using this conversion method.

Asthma

This feed focuses in Asthma in which your airways narrow and swell. This can make breathing difficult and trigger coughing, wheezing and shortness of breath.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
