A sustained release theophylline preparation: efficacy in childhood asthma with low serum theophylline levels

G S Rachelefsky et al. Ann Allergy. 1978 Apr.

Abstract

In a double-blind, crossover study a sustained release theophylline preparation was found to be effective and safe while controlling the symptoms and improving the measured pulmonary function of 16 chronic childhood asthmatics. Serum theophylline levels between 2.5 and 8.1 microgram/ml were adequate for control of clinical disease.
