Antitussive effect of herbal medicine bakumondo-to: a case report.

Abstract: A 50 year-old woman with progressive systemic sclerosis accompanied by interstitial pneumonia complained of a dry cough. A variety of antitussive agents were given for the dry cough over a one year period, but her symptoms continued. However, when a herbal medicine Bakumondo-to was administered, her intractable dry cough subsided dramatically within 10 days. Bakumondo-to may be a good antitussive agent for interstitial pneumonia associated with a dry cough that is resistant to other antitussives.

Interaction of papaverine with the enalapril-induced cough in guinea pig

Abstract: Background Angiotensin Converting Enzyme Inhibitors (ACEIs) like enalapril are extremely effective in the treatment of hypertension and heart failure. One of the most important side-effects of these drugs which can lead to cessation of therapy is a persistant dry cough, induced because of increased bradykinin levels in the lung. Although antitussive alkaloids like codeine are effective in suppressing this cough, they too present a wide range of side-effects, most notably addiction. Objective In a previous work we were able to show that noscapine, a non-narcotic antitussive agent, was able to decrease enalapril induced cough in guinea pigs. In this work, papaverine, another non-narcotic alkaloid found in opium latex was tested in the guinea pig model for antitussive activity. Method Cough was induced in enalapril pretreated guinea pigs by forcing the animals to inspire capsaicin aerosol in an air-tight chamber. Coughs were recorded in control animals and in those which had received different doses of papaverine. Characteristic changes in chamber air pressure, were detected by a pressure transducer. Results . At low doses (0.5 and 0.25 mg/kg) papaverine was able to decrease enalapril induced cough. CONCLUSION. This effect was not mediated by the action of the drug on mu receptors and was only observed in animals treated with enalapril.
