Abstract
A series of cats, anaesthetized with chloralose, was given intravenously a sufficient quantity of mecamylamine to produce hypotension and a 50% neuromuscular block. Inhalation of carbon dioxide then produced a further depression of blood pressure and an increase in the neuromuscular blocking effect. It was shown that, following the administration of carbon dioxide, the plasma mecamylamine levels increased coincident with the increased pharmacological effects.
