Theophylline is a xanthine derivative.<\/p>\n

Mechanism of Action: <\/strong>Theophylline relaxes bronchial smooth muscle by inhibition of the enzyme phosphodiesterase and suppresses airway responsiveness to stimuli that cause bronchoconstriction.<\/p>\n

Indications: <\/strong>Theophylline is used for the long-term management of persistent asthma that is unresponsive to beta-agonists or inhaled corticosteroids.<\/p>\n

Nursing Considerations: <\/strong>Nurses should remind patients that xanthine derivatives are not quick relief medications for asthma attacks. Due to potential CNS stimulation, administer this medication in the morning\u00a0 when possible.<\/p>\n

Side Effects\/Adverse Effects: <\/strong>Theophylline can cause nausea, vomiting, CNS stimulation, nervousness, and insomnia.[1]<\/sup><\/a><\/sup><\/p>\n
