The Food and Drug Administration (FDA) has approved a supplemental New Drug Application (sNDA) for Movantik (naloxegol AstraZeneca) tablets.

The sNDA proposed changes including: information regarding the administration of crushed tablets mixed in water given orally or via nasogastric (NG) tube, the addition of severe abdominal pain and/or severe diarrhea to the Warnings and Precautions and Adverse Reactions sections, and a clarification to the effects of race on pharmacokinetics. 

The updated labeling for Movantik now states that for patients who are unable to swallow the Movantik tablet whole, the pill can be crushed to a powder, mixed with 4oz (120mL) of water and consumed immediately. The glass should be refilled with 4oz (120mL) of water, stirred and the contents consumed. Also, Movantik can be administered via a NG tube with specific instructions listed under Dosage and Administration.
