OSMOHALE is a pharmaceutical product designed to assist in the diagnostic evaluation of respiratory conditions, particularly those affecting the airway responsiveness such as asthma. It works by inducing a controlled temporary narrowing of the airways (bronchoconstriction) through the inhalation of a hyperosmolar solution. This process helps healthcare professionals assess the sensitivity and reactivity of the airways, which is crucial for diagnosing asthma, evaluating its severity, and monitoring the effectiveness of treatment strategies. OSMOHALE is typically administered in a clinical setting under the supervision of medical professionals to ensure safety and accuracy in the diagnostic process.
