A clinician’s guide to single vs multiple inhaler therapy for COPD

introduction: in the management of chronic obstructive pulmonary disease (COPD), inhalation therapy plays a pivotal role. however, clinicians often face the dilemma of choosing between single and multiple inhaler therapies for their patients. this choice is critical because it can affect treatment efficacy, patient adherence, and overall disease management. areas covered: this article examines the advantages and factors to be taken into consideration when selecting between single and multiple inhaler therapies for COPD. expert opinion: both single and multiple inhaler therapies must be considered in COPD management. while single inhaler therapy offers simplicity and convenience, multiple inhaler therapy provides greater flexibility and customization. clinicians must carefully evaluate individual patient needs and preferences to determine the most appropriate inhaler therapy regimen. through personalized treatment approaches and shared decision-making, clinicians can optimize COPD management and improve patient well-being. nevertheless, further research is required to compare the effectiveness of single versus multiple inhaler strategies through rigorous clinical trials, free from industry bias, to determine the optimal inhaler strategy. smart inhaler technology appears to have the potential to enhance adherence and personalized management, but the relative merits of smart inhalers in single inhaler regimens versus multiple inhaler regimens remain to be determined.
