Theophylline is a drug primarily used to treat respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). It functions by relaxing the smooth muscles of the bronchial airways and opening up air passages, thus making it easier to breathe. Theophylline also suppresses the response of the airways to stimuli that trigger an asthmatic response.

Regular monitoring of theophylline levels in the blood is essential due to its narrow therapeutic index; this means that there's only a small difference between the drug's therapeutic level and toxic level. Therefore, it's crucial to ensure the right dosage of theophylline, avoiding too little (which wouldn't relieve symptoms) or too much (which could cause toxic effects).
