Mechanism of action

Uniphyl Cr functions as a bronchodilator by inhibiting phosphodiesterase enzymes, which increases cyclic adenosine monophosphate (cAMP) levels. This relaxation of bronchial smooth muscles helps open constricted airways, facilitating easier breathing for patients with chronic respiratory conditions, and also has mild anti-inflammatory properties.
