Changes of human plasma dopamine-beta-hydroxylase activity after intravenous administration of theophylline.
The intravenous administration of theophylline to ten healthy human subjects produced either an increase of circulating plasma dopamine-beta-hydroxylase or no change. The rise of plasma enzyme activity may reflect the increased peripheral catecholamine release induced by theophylline.
