Forty-five patients with chronic obstructive pulmonary disease were studied to compare the acute effects of ipratropium bromide (60 µg), salbutamol (300 µg) and placebo (3 puffs) on the forced expiratory volume in 1 sec (FEV 1) and forced vital capacity (PVC). Ipratropium bromide produced a significantly greater improvement than salbutamol in both FEV1 and FVC at 15,60 and 180 minutes afte...

Therefore, the phytotoxicity of cetrimonium bromide was tested to evaluate its acute toxicity to plants and possible toxicity to other organisms and the ecosystem. Results: The germination rates of two test species, Lactuca sativa and Brassica campestris...
