Ketamine for Mild to moderate pain
Adult weight-based dosing has a median of 0.3 mg/kg across 78 published protocols, with the middle half between 0.25 and 0.375.
1,335 rows are under review across the census and excluded from every number on this page. How that works.
Adult, weight-basedmg/kg
| min | p25 | median | p75 | max |
|---|---|---|---|---|
| 0.2 | 0.25 | 0.3 | 0.375 | 0.5 |
Values in mg/kg. One value per source (that source's median), so a document listing a drug five times still gets one vote.
