Formerly Academic Unit of Human Psychopharmacology, Department of Psychological Medicine, Medical College of St Bartholomew's Hospital, London EC1A 7BE, Department of Psychological Medicine, University of Otago, New Zealand We studied the effect of single doses of the 5-HT1A agonist buspirone (10 mg and 20 mg) on food intake during the menstrual cycle of nine healthy women, none of whom were on a contraceptive pill. In a double-blind placebo-controlled trial, subjects were tested over three cycles, receiving one treatment per cycle. Within each cycle, they were tested at two time points; mid-follicular and late luteal. Food intake following 20 mg buspirone was significantly higher in the luteal phase, suggesting the possibility of pre-menstrually enhanced 5-HT receptor sensitivity.
