Influence of electric foot shock on pharmacokinetics of isosorbide dinitrate subcutaneously administered to rats.
The influence of emotional stress on the pharmacokinetics of isosorbide dinitrate (ISDN) administered s.c. to rats was studied. The plasma level of ISDN in emotionally stressed (ES) rats was the same as that in non-stressed control rats. However, the levels of its metabolites, 5-isosorbide mononitrate (5-ISMN) and 2-isosorbide mononitrate (2-ISMN), were markedly lower in ES rats than in the control rats. On the other hand, urine ISDN and 2-ISMN excretion rates were lower in ES rats than in the control rats. These observations suggest that the pharmacokinetics of ISDN administered s.c. is influenced by emotional stress such as foot shock.
