This study found that 1.25 mg of fenoterol is an effective starting dose for nebulized asthma treatment. Higher doses offered minimal additional benefit and increased side effects in stable asthmatics.

Area of Science:

  • Pulmonology
  • Pharmacology

Background:

  • Asthma management requires effective bronchodilators.
  • Determining optimal drug dosage is crucial for balancing efficacy and safety.

Purpose of the Study:

  • To identify the optimal nebulized fenoterol dose for asthmatic patients.
  • To compare the efficacy and side-effect profiles of different fenoterol doses.

Main Methods:

  • A double-blind, placebo-controlled study involving 20 asthmatic patients.
  • Lung function was measured after administration of placebo and four fenoterol doses (0.5, 1.25, 2.5, 5 mg).

Main Results:

  • All fenoterol doses were significantly more effective than placebo.
  • Higher doses (2.5 mg, 5 mg) showed greater efficacy than 0.5 mg up to 3 hours.

  • No significant difference in efficacy was observed between the three highest doses.

    • Conclusions:

    • 1.25 mg of nebulized fenoterol is recommended as a starting dose for stable asthmatics.
    • Higher doses provide limited additional bronchodilation but increase side effects.
    • Severely ill patients may require higher doses where side effects are less critical.
