“2 When applied iontophoretically, pregnenolone sulphate, cyproterone , and norethindrone enhanced the actions of iontophoretically applied adenosine and failed to potentiate the depressant effects of adenosine 5′‐N‐ethylcarboxamide and γ‐aminobutyric acid.”
“3 Cyproterone acetate (50 μg kg−1) and progesterone (200 μg kg−1) administered intravenously enhanced the depressant actions of iontophoretically applied adenosine.”
