The pharmacokinetic profile of Sobrerol, a mucolytic drug, has been studied in patients with acute exacerbations of chronic bronchitis and dense sputum. In addition to measurement of serum and urine levels, the concentration in bronchial mucus was also examined, and their correlation was calculated. Mass fragmentographic analysis was used to assay free sobrerol and its principal urinary metabolites hydrated carvone and glucuronidated sobrerol. After the doses and administration routes used, there appeared to be accumulation of sobrerol in bronchial mucus. This is a feature of great interest and value for a drug which has the specific action of liquifying mucus.
