Summary A double-blind, cross-over comparison of a new, rapidly dissolving tablet of theophylline (Nuelin®), with a standard aminophylline tablet (Theodrox®), and a tablet containing a combination of theophylline, ephedrine and hydroxizine (Marax®) was made during six 4-day periods of ambulatory treatment of 24 adults with moderately severe asthma. Nuelin (125 mg four times a day) and Theodrox (195 mg aminophylline, equivalent to 150 mg theophylline, four times a day) were equally effective in the treatment of asthma when daily records of peak expiratory flow (PEF), daily records of symptoms according to a questionnarie, or the number of isoprenaline puffs required to control symptoms, were used as measures of activity. During treatment with Marax, PEF was significantly higher than during treatment with the two theophylline preparations. Treatment with Marax was also associated with the lowest scores for respiratory symptoms and the smallest usage of additional isoprenaline aerosol, but the differences between treatments were not statistically significant. Side-effects, especially palpitations and tremor, were more common after Marax than after Nuelin or Theodrox. Recent pharmacokinetic studies have suggested that a further clinical trial of higher doses of Nuelin is required for complete evaluation of this preparation.
