In a double-blind trial, 29 patients were treated for stable, chronic bronchitis with iodinated glycerol (Organidin, 60 mg four times daily; n = 16) or placebo (n = 13). The study consisted of a 2-week single-blind lead-in period, followed by a 6-week double-blind treatment period, and assessed a total of 50 response variables. In this set of patients, treatment with iodinated glycerol was associated with statistically significant (P < 0.05) and/or positive trend (P < 0.1) toward improvement in cough frequency, cough severity, difficulty in raising sputum, sputum thickness, sputum stickiness, forced expiratory flow at FVC25%-75%, cell concentration in sputum, and several measures of physician assessment of patient condition. Iodinated glycerol was well tolerated during the 6-week treatment period; no adverse effects were reported and no patient receiving iodinated glycerol withdrew from the study prematurely. In conclusion, this study demonstrates that iodinated glycerol, 60-mg tablets given in a total daily dose of 240 mg, is safe and effective therapy for reducing symptoms in patients with stable, chronic bronchitis.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed).

D003371	Cough	A sudden, audible expulsion of air from the lungs through a partially closed glottis, preceded by inhalation. It is a protective response that serves to clear the trachea, bronchi, and/or lungs of irritants and secretions, or to prevent aspiration of foreign materials into the lungs.	Coughs
