Aminophylline / Potassium Iodide
Aminophylline/Potassium Iodide is a combination bronchodilator and expectorant used to treat respiratory conditions characterized by airway constriction and excessive mucus production, such as chronic bronchitis and certain asthma presentations. The aminophylline component relaxes bronchial smooth muscles to widen airways, while potassium iodide helps thin and loosen respiratory secretions for easier clearance. This medication has become less commonly prescribed in modern practice due to the availability of safer alternatives and the need for careful therapeutic monitoring.

Used for respiratory conditions involving bronchoconstriction and thick mucus secretions, including chronic bronchitis, asthma, and emphysema. Typically considered when standard therapies are insufficient.
Aminophylline (a theophylline derivative) relaxes smooth muscles in the bronchial airways, widening passages and improving airflow. Potassium iodide acts as an expectorant, thinning respiratory secretions to facilitate their removal through coughing.
Requires monitoring of theophylline blood levels due to narrow therapeutic window. Iodine component is contraindicated in patients with thyroid disorders or iodine allergies. Multiple drug interactions exist, particularly with antibiotics, antifungals, and cardiovascular medications. May cause GI upset, tachycardia, or nervous system effects.
