Abstract

Background/Aim:Liraglutide, a glucagon-like peptide-1 analog, induces weight loss. We investigated whether liraglutide affects gastric accommodation and satiation by measuring the intragastric pressure (IGP) during nutrient-drink consumption and using the barostat technique.Methods:Ten healthy volunteers (HVs) were tested after placebo, 0.3, 0.6 or 1.2 mg liraglutide administration. IGP was studied during intragastric nutrient-drink (1.5 kcal ml(-1)) infusion (60 ml min(-1)), while the HVs scored their satiation on a graded scale until maximal satiation. In a separate session, isobaric distentions were performed using the barostat with stepwise increments of 2 mm Hg starting from minimal distending pressure, although HVs scored their perception; gastric volume was monitored 30 min before and until 60 min after ingestion of 200 ml of nutrient drink. Data are presented as mean±s.e.m. comparisons were performed with ANOVA (P<0.05 was significant).Results:During nutrient-drink infusion, IGP decreased with 4.1±0.7, 3.0±0.4, 2.1±0.3 and 2.6±0.4 mm Hg (placebo, 0.3, 0.6 and 1.2 mg liraglutide, respectively; P<0.05). The maximum-tolerated volume was not different, except after treatment with 1.2 mg liraglutide (695±135 ml) compared with placebo (1008±197 ml; P<0.05); however, 1.2 mg liraglutide induced nausea in all volunteers. In the barostat study, liraglutide did not affect the perception or compliance, but significantly decreased gastric accommodation to the meal (168±27 vs 78.8±36.4 ml after treatment with placebo and 0.6 mg liraglutide, respectively; P<0.05).Conclusion:Although no effect on perception, compliance or satiation was observed, liraglutide inhibited gastric accommodation. Whether this effect is involved in the anorectic effect of liraglutide remains to be determined.
