Olodaterol / tiotropium
"A few weeks ago my physician gave me a sample of this to try since the Syymicort I had been using for more than 2 years was no longer as effective as it had been. I've been using this once a day now for about 3 weeks and have had considerable relief. It did take me a couple of days to get the hang of using this new style delivery system. It's really easy to push the delivery button before you get your mouth over the respimat properly ."
