### Other work

Ahlquist's other scientific work also includes the [pharmacology](/wiki/Pharmacology "Pharmacology") of the sympathetic [nervous system](/wiki/Nervous_system "Nervous system"). His research contribute to the discovery of [tolazoline](/wiki/Tolazoline "Tolazoline"), a substance with a completely different [chemical structure](/wiki/Chemical_structure "Chemical structure") than the adrenaline and noradrenaline and in 1958, [dichloroisoprenaline](/wiki/Dichloroisoprenaline "Dichloroisoprenaline") the first clinically useful beta\-blocker. It was discovered with his help that the [peristalsis](/wiki/Peristalsis "Peristalsis") is enhanced by [α\-adrenoceptors](/wiki/%CE%91-adrenoceptor "Α-adrenoceptor") and conversely inhibited by β\-adrenoceptors.

In his most recent essay in 1980, he looked back to the 1948 publication. The impact of the 1948 publication is evident by the number of times it has been cited (2766 times as of 2011\).
