    Theophylline is a xanthine derivative.

    Mechanism of Action

    Theophylline relaxes bronchial smooth muscle by inhibition of the enzyme phosphodiesterase and suppresses airway responsiveness to stimuli that cause bronchoconstriction.

    Indications for Use

    Theophylline is used for the long-term management of persistent asthma that is unresponsive to beta agonists or inhaled corticosteroids.

    Adverse/Side Effects

    Theophylline can cause nausea, vomiting, CNS stimulation, nervousness, and insomnia.[1]

    Patient Teaching & Education

    Patients should be sure to take medications as prescribed at appropriate intervals. They should avoid irritants and drink fluids to help thin secretions. Patients will need serum blood levels tested every six to twelve months.[2]

    Now let’s take a closer look at the medication grid on theophylline in Table 5.14.[3], [4],[5]
