AB  - l-ABT is a hypotensive agent; d-ABT produces a biphasic blood pressure response—a rise is followed by a fall. The rise results from epinephrine release. The exact mechanism for the hypotensive actions following d- and l-ABT is unknown. d- and l-ABT slow the heart slightly and decrease the amplitude of heart contractions. Suppression of nictitating membrane contractions evoked by postganglionic stimulation was noted following d- and l-ABT. These substances also blocked hypertension caused by stimulation of the hepatic nerve. d- and l-ABT potentiate muscle paralysis by d-tubocurarine. APMT produces moderate rises in blood pressure and occasionally some enhancement of gut activity. The significance of this relative lack of pharmacological response is discussed.
