Comparisons between the antianesthetic action of dibutyryl cyclic AMP and analeptic drugs on amobarbital-induced narcosis in the rat.
The dose-related antianesthetic and antidotal property of dibutyryl cyclic AMP, devoid of toxic effects, imparts uniqueness to the nucleotide as an arousal agent. Of the analeptic drugs studied (d-amphetamine, picrotoxin, pentylenetetrazol, caffeine, theophylline, strychnine, ethamivan and doxapram), only picrotoxin demonstrated antianesthetic properties. However, picrotoxin was associated with severe toxicity at all dose levels tested. No analeptic drug is effective in reversing the central nervous system depression produced by sedative, hypnotic or tranquilizer drug overdosage.
