molecules benztropine mesylate and deptropine citrate were selected for further validation and both potently inhibited sphere formation and self-renewal of BCSCs in vitro. Benztropine mesylate treatment decreased cell subpopulations with high ALDH activity and with a CD44+/CD24- phenotype. In vivo, benztropine mesylate inhibited tumor-initiating potential in a 4T1 mouse model. Functional studies indicated
A comparison of ipratropium bromide, deptropine citrate and placebo in asthma and chronic bronchitis. A new anticholinergic aerosol, ipratropium bromide, was compared in a double-blind cross-over trial with an established preparation, deptropine citrate, and placebo in 16 patients with defined asthma or chronic bronchitis. Ipratropium bromide produced a significantly greater and more rapid bronchodilation than did deptropine citrate or placebo in the doses used, and its effect was slightly greater in the asthmatic than in the chronic bronchitic group. No unwanted effects on secretion were seen with ipratropium bromide.
groups had the disposal of the asthma and COPD guidelines routinely distributed by the Dutch College of General Practitioners. We measured the average number of contacts, FEV 1 (forced expiratory volume), and peak-flow measurements per asthma/COPD patient per practice; and, the average number of antihistamine, cromoglycate, deptropine, and oral bronchodilator prescriptions per asthma/COPD patient per
