[Propranolol and pindolol in chronic obstructive lung disease (author's transl)]. 1976

W T Ulmer, and K Lanser

The effects of 5 mg pindolol and 100 mg propranolol on the airway resistance were compared with a placebo in an inter-individual double blind trial in eight patients with chronic obstructive lung disease. Six hours after drug administration the patients inhaled two puffs of fenoterol (0.4 mg) from a metered aerosol to test the reversibility of the bronchoconstrictive effect. Airway resistance and intrathoracic gas volume were measured by body plethysmography. Propranolol increased the airway resistance significantly (P less than 0.01). The highest increase with a mean of 44% was measured two hours after ingestion. After six hours the mean increase was still 18%. Pindolol showed a barely detectable, statistically insignificant bronchoconstrictive effect in comparison with the placebo. With regard to the circulatory effects 5 mg pindolol and 100 mg propranolol were aequipotent, propranolol had a more pronounced effect in lowering the pulse rate, pindolol in lowering the blood pressure. Fenoterol can reduce airway resistance even after beta-blockade, but the effect was more profound after the placebo than after the beta-blocker.

UI	MeSH Term	Description	Entries
D008173	Lung Diseases, Obstructive	Any disorder marked by obstruction of conducting airways of the lung. AIRWAY OBSTRUCTION may be acute, chronic, intermittent, or persistent.

D010869	Pindolol	A moderately lipophilic beta blocker (ADRENERGIC BETA-ANTAGONISTS). It is non-cardioselective and has intrinsic sympathomimetic actions, but little membrane-stabilizing activity. (From Martindale, The Extra Pharmocopoeia, 30th ed, p638)	Prindolol,LB-46,Visken,LB 46,LB46
D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.	Sham Treatment
D010993	Plethysmography, Whole Body	Measurement of the volume of gas in the lungs, including that which is trapped in poorly communicating air spaces. It is of particular use in chronic obstructive pulmonary disease and emphysema.

D011433	Propranolol	A widely used non-cardioselective beta-adrenergic antagonist. Propranolol has been used for MYOCARDIAL INFARCTION; ARRHYTHMIA; ANGINA PECTORIS; HYPERTENSION; HYPERTHYROIDISM; MIGRAINE; PHEOCHROMOCYTOMA; and ANXIETY but adverse effects instigate replacement by newer drugs.

D011674	Pulse	The rhythmical expansion and contraction of an ARTERY produced by waves of pressure caused by the ejection of BLOOD from the left ventricle of the HEART as it contracts.	Pulses

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). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic
