Stability of formoterol concentration in scalp hair of patients using maintenance formoterol therapy for asthma or COPD (INCTFISH)
The pilot study reveals a strong correlation between formoterol concentrations in segment one and two, indicating that drug levels remain stable in hair over a period of at least 3 months. While the study does not yet provide sufficient evidence to establish the utility of hair testing for monitoring formoterol adherence, it provides important directions for future research.
