By M. F. Cuthbert and K. Owusu-Ankomah


1. DL-1-(2-acetyl-4-n-butyramidophenoxy)-2-hydroxy-3-isopropylaminopropane hydrochloride (M & B 17803A) was given to four healthy volunteers in single oral doses of up to 300 mg. There were no subjective effects and no significant alterations in the heart rate, systolic and diastolic blood pressure in the seated position or in the forced expiratory volume or in the electrocardiogram within 6 h of the dose.
