Abstract: | In a group of alcoholic patients salivary output was measured before stimulation, during anticipation of tasting lemon juice, and after stimulation with lemon juice. These measures were obtained twice a day (a.m.-p.m.). Either amitriptyline or a placebo had been administered to each patient. The dental-roll technique for measuring salivary output was demonstrated to be reliable over time. In patients who had received the placebo salivary output in anticipation of the taste of lemon juice demonstrated an extinction phenomenon. Amitriptyline inhibited this anticipatory response. No relationship between the subjective symptom of dry mouth and salivary output was found. The results are interpreted as indicating that amitriptyline inhibits welldeveloped conditional anticipatory responses and that the symptom of dry mouth probably occurs predominantly during the hours immediately preceding mealtimes. |
