Theophylline is a drug still used to reverse airflow obstruction associated with chronic lung diseases i.e. asthma, COPD, chronic bronchitis, and emphysema. It works by two mechanisms: smooth muscle relaxation (bronchodilation) in the bronchioles mediated by inhibition of phosphodiesterase III (PDE III) and suppression of the response of airways to stimuli by an unknown mechanism. Theophylline is also thought to increase contraction of the diaphragm muscles. Because of theophylline’s similarity in structure to caffeine, it produces a well-known caffeine-like side effect profile such as insomnia, nausea, and headache. Serious adverse effects can occur at higher doses especially in overdoses. Although used less frequently since the advent of alterative inhaled therapies, theophylline still maintains its place in therapy for those who need special consideration. Theophylline has also been used extensively in the veterinary population particularly for dogs.
