Comments on subacute and long-term studies.
Long-term therapy with Duovent was always superior in comparison to the other drugs. An immediate efficacy with increasing levels until the 90th day was always obtained. There were no signs of tachyphylaxis and side effects were insignificant. Functional modifications were evident in the large and small airways.
