The effect singly and in combination of methylprednisolone and troleandomycin (TAO) on methacholine sensitivity was studied in eight mildly asthmatic patients who did not require regular bronchodilator therapy. Neither drug alone nor in combination significantly altered the bronchial reactivity to methacholine.
