We investigated whether blood-to-cerebrospinal fluid (CSF) transfer of liraglutide occurs, and if so, whether it associates with clinical weight loss following liraglutide treatment in humans. We performed lumbar puncture and blood sampling in eight patients with type 2 diabetes (mean (range)): age 63 (54-79) years; actual body weight: 90 (75-118) kg treated with 1.8 mg liraglutide for 14 (5-22) months and with a treatment-induced weight loss of 8.4 (7-11) kg. We measured liraglutide in plasma and CSF with a radioimmunoassay specific for the N-terminus of the GLP-1 moiety of liraglutide. Mean plasma liraglutide was 31 (range: 21-63) nmol l(-1). The mean CSF-liraglutide concentration was 6.5 (range: 0.9-13.9) pmol l(-1).
