Effects of drugs affecting endogenous amines or cyclic nucleotides on ethanol withdrawal head twitches in mice.


1 Twenty-four hours after ethanol withdrawal, dependent mice exhibited frequent head twitching. Naive mice exhibited similar twitching 15 min after treatment with 5-hydroxytryptophan (5-HTP) or 6 h after alpha-methyl-p-tyrosine (AMPT).
