People suffering from smoking-related lung disease are less likely to die if they take particular drug everyday.

Tiotropium is the only capable drug to improve the survival of patients with chronic obstructive pulmonary disease(COPD). The drug has been here for seven to eight years, but not been used as it is relatively expensive. Tiotropium drug lowered the people suffering COPD of dying by 16%. It also relieved their cough and breathlessness, which means improvements in their quality life.

The people suffering COPD had 14% fewer attacks of breathlessness a year and were 14% less likely to need hospitalisation for these attack.The functioning of their lungs has improved by 10%.

Most patient suffering COPD decline th expensive drug but continue using the cheaper ones which is shorter actings ones. So the COPD association had hold a symposium for doctors on telling COPD instead of asthma.
