What happens
Slowed absorption of acetaminophen
Interaction Deep Dive
Use of acetaminophen following lixisenatide administration may slow the absorption of acetaminophen due to delayed gastric emptying. While no change in acetaminophen Cmax or Tmax was observed with acetaminophen administration 1 hour before lixisenatide, acetaminophen Cmax decreased by nearly one-third and Tmax was delayed by about 2 hours with administration 1 and 4 hours after lixisenatide. If concomitant use of these agents is required, administer acetaminophen at least 1 hour before lixisenatide to avoid the delay in effect of acetaminophen1.
Why it happens (mechanism)
Delayed gastric emptying
Literature reports

a) Administration of a single dose of acetaminophen 1000 mg before or after lixisenatide 10 mcg did change acetaminophen AUC. When acetaminophen was administered 1 hour before lixisenatide, no effects on acetaminophen Cmax and Tmax were observed; however, when administered 1 and 4 hours after lixisenatide 10 mcg, Cmax of acetaminophen was decreased by 29% and 31%, respectively, and median Tmax was delayed by 2 and 1.75 hours, respectively 1.
