The present invention is directed to methods and compositions for treating pulmonary disease comprising delivering directly to a patient’s lungs a therapeutically effective amount of oxybutynin in combination with one or more pharmaceutically effective agents. At the decoding side, decoding operations are performed by using a principle corresponding to that at the coding side. For each field type, it is preferred to display a list of field contents within that type, filtered to remove repeated incidence of the same content. The enhanced gripping means are provided by a toothed gripping means or a friction enhancing means.
