Modern medicine has seen drastic shifts in its approach to patient care over the past decade. The practice of precision medicine is gaining importance due to the current expansion of our understanding of molecular mechanisms in disease pathology and the individual variabilities of the same. Mechanisms of asthma vary from person to person. The underlying pathology determines the response to treatment.

Tailoring therapy on an individual basis optimizes response. Traditional classification of asthma was primarily based on the symptoms alone. But better understanding of molecular mechanisms and its association with clinical features has led to an increasing implementation of phenotyping in the treatment of asthma. The responses to therapies vary with regard to age, triggering factors, underlying mechanism, presence or absence of airway remodeling and genetic make-up of the patient.…
