It is concluded that delay of castor oil‐induced diarrhoea in rats allows a detailed characterization of aspirin‐like compounds, and that inhibition of prostaglandin biosynthesis is insufficient to suppress the intestinal effects of the oil.

The method is found to yield clear-cut data that are specifically related to drug discrimination learning without being possibly confounded by state dependent effects and the experimental procedure is designed so as to provide an appropriate measurement of operant response modulating drug effects.

Risperidone can be characterized as a potent D2 antagonist with predominant 5HT2 antagonistic activity and optimal pharmacokinetic properties.

The hypnotic effects of etomidate at very low dose levels in different laboratory animals are compared with the effects obtained in human subjects, in which successful induction of anaesthesia was obtained without producing any release of histamine and with only minimal effects on cardiovascular and respiratory functions.
