Abstract
The principal activity of the amides of ethanol-.beta.-aminophosphoric acid with active moieties having anti-inflammatory and analgesic activity (FANS) remains substantially unchanged but they have considerably lower toxicity particularly in terms of damage to the stomach. The method for their preparation is also described.
