Metoclopramide appears to be a promising candidate for the treatment of patients with intractable hiccups, with mild adverse events. Metoclopramide nasal spray offers better symptom control than metoclopramide oral tablet in diabetic patients with symptoms of gastroparesis. Metoclopramide increases peristalsis of the jejunum and duodenum, increases tone and amplitude of gastric contractions, and relaxes the pyloric sphincter and duodenal bulb, while simultaneously increasing lower esophageal sphincter tone.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
