Fig. 4From: Evaluation of systemic absorption and bronchodilator effect of glycopyrronium bromide delivered by nebulizer or a dry powder inhaler in subjects with chronic obstructive pulmonary diseaseComparison of GLY/eFlow versus GLY/DPI fully dose-normalized systemic exposure to glycopyrronium bromide. Note: Lower SD bars are missing where values are below zero; negative values cannot be displayed on a logarithmic scale. DPI, dry powder inhaler. GLY, glycopyrronium bromide. IV, intravenous.
