Patient summary

Uniphyl CR is theophylline 400mg as a modified-release tablet rather than a capsule, for asthma and COPD. It inhibits the phosphodiesterase enzymes.

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.

Pregnancy and breastfeeding

Pregnancy: Use only if benefit outweighs risk. Breastfeeding: Exercise caution; may cause irritability in the infant.

Uniphyl CR is a controlled-release tablet containing theophylline, a standard treatment for managing asthma and chronic obstructive pulmonary disease. This medication helps open airways to improve breathing. The same active ingredient is also available under brand names like Nuelin SA and Slo-phyllin, available in 400mg tablet strengths.
