The possibility of a functional interdependence between central GABAA receptors and beta 2-adrenoceptors has been investigated using the ability of both types of agonist to potentiate the tic (head-twitch) response to 5-methoxy-N,N-dimethyltryptamine in the mouse. At a dose which selectively antagonised beta 1- but not beta 2-adrenoceptors, ICI 118,551 abolished the effects of single doses of muscimol, diazepam and pentobarbitone. Conversely, bicuculline abolished the potentiation caused by the beta 2-adrenoceptor agonist procaterol. Thus there is preliminary evidence that these two receptor types do show mutual interdependence.
